Thin Air Energy, a globally renowned provider of energy storage and LED lighting technology solutions, has announced two new breakthrough products in the COVID-19 era. The first product is TORCH UVc, a germicidal, anti-viral product that emits ultraviolet light in the UVc spectrum, where germs and viruses are killed. Germicidal and anti-viral products It has a novel feature, which is believed to substantially increase germ killing effectiveness. The second product is GEIGER UVc, which is a device used for measuring the instant intensity of UVc and accumulated dosing of UVc radiation. "Thin Air Energy is at the forefront of germicidal and anti-viral products for home and office use," said James Wiebe, CEO of Thin Air Energy, adding "These two new products provide an enormous benefit to the user, along with a simple way to measure the field strength and dose of UVc radiation." TORCH UVc TORCH UVc features a patent pending mode of operation, which modulates the UVc output TORCH UVc features a patent pending mode of operation, which modulates the UVc output in such a way that the efficacy may be substantially improved. This special enhanced kill feature of TORCH UVc may be enabled or disabled as desired by the user. If disabled, the product emits a conventional, continuous output of UVc. The product is designed with solid state LEDs and is not tube based. Consequently, the product will also last longer. TORCH UVc also includes another patent pending feature, a very bright white LED light, which flashes and alerts the user that the product is turned on and is potentially dangerous. This feature is more effective than the soft purple glow that many UVc devices emit. The flashing white LED light actively discourages users from looking into the UVc output. GEIGER UVc The GEIGER UVc allows users to easily measure the field strength of UVc radiation. GEIGER UVc measures the field strength of only UVc, ignoring UVa and UVb (which are commonly used in tanning salons and resin curing lights, and also potentially in fake UVc devices). GEIGER UVc also has great resistance to visible light as well. GEIGER UVc is the size of a key fob, and in addition to showing continuous UVc field strength (in milliwatts), it also measures the cumulative dosing, providing an LED alarm indication when 5,000 millijoules and then 30,000 millijoules of radiation have been detected. These dosing levels reflect dosing known to be effective for disinfection from published literature for certain germs and viruses. When the dosing level is achieved, a LED on GEIGER UVc turns on. Intensive R&D in product development Both products were designed with careful attention to a large number of published papers, including research and development that shows the improved germicidal efficacy of UVc when appropriately modulated. Our products are designed with science and are patent pending, state of the art, with improved safety and efficacy" "The internet is already filled with stories of fake UVc light sources that inadequately kill germs," James Wiebe said. He adds, "Social media is a plethora of cheap, featureless UVc devices of unknown strength and quality. Our products, in contrast, are designed with science and are patent pending, state of the art, with improved safety and efficacy." Products availability These products are available for pre-order on the official Thin Air Energy company website and through additional retailers in the coming months. The cost of raw UVc LEDS is rapidly rising in the current COVID-19 pandemic scenario, with prices being subject to change without notice.
Quality control, product performance and safety are topics which are being focused on more and more in a world driven by price competitiveness.

When a visionary industrial designer turns his attention to the HVAC industry, it’s probably wise to take note. Recently, technology entrepreneur and philanthropist, Elon Musk expressed his vision for residential HVAC, based in part on a new heat pump his engineers designed for the Tesla Model Y electric compact sport utility vehicle. Efficient, quiet home HVAC system According to several reports, Musk seeks to build an efficient and quiet HVAC system for the home, piggybacking on the technology used to make heaters for the newest Tesla Model Y. It’s the first of Tesla’s electric cars to use a heat pump, which is more efficient than previous electric heating systems. Tesla’s previous vehicle models used resistance heating, which is a battery hog Tesla’s previous vehicle models used resistance heating, which is a battery hog. The new heat pump component, including a compressor/chiller and liquid cooled condenser, is designed to be more energy-efficient and provides a more reliable vehicle operation range in cold weather conditions. Model Y heat pump “The model Y heat pump is some of the best engineering I’ve seen in a while,” said Musk on Twitter, adding “[The] team did next-level work.” Musk would ‘love to do HVAC that’s quiet and efficient with humidity control and HEPA filter’ for the home. Tesla car-inspired temperature controls Musk stated that he imagines a full-home HVAC system that is inspired by and maybe linked with the temperature controls inside someone’s Tesla vehicle. The proposal is in line with Musk’s mission to accelerate the advent of sustainable energy. He said, “Reducing a home’s energy usage while deploying solar power capacity are complementary goals”. High-efficiency particulate air filters Tesla HEPA filters are about 10 times larger than a normal automotive cabin air filter Tesla already has experience with HVAC systems and high-efficiency particulate air (HEPA) filters used to clean the cabin air in their Model 5 and Model X vehicles. The Tesla HEPA filters are about 10 times larger than a normal automotive cabin air filter and about “100 times more effective,” according to the company. Tesla HEPA filters The filters remove at least 99.97% of the fine particulate matter and gaseous pollutants, as well as bacteria, viruses, pollen and mold spores. Tesla refers to the extreme level of air cleaning as ‘Bioweapon Defense Mode’. Among other benefits, the filtering system protected California drivers from smoke and kept the vehicles’ cabin air clean during the recent wildfires. Musk first mentioned home air conditioning systems about two years ago, alluding to a home HVAC system that is quiet and efficient with humidity control and a HEPA filter. HEPA filter in a home system “The use of a HEPA filter in a home system would be a ‘life changer’ for people with allergies”, says Musk. The growing popularity of home air purifier products supports the conclusion. Communication between a Tesla vehicle and a Tesla home climate system would allow an intelligent air conditioning system to ‘know’ exactly when a resident will get home and only cool the home as appropriate to save energy. Energy-efficient, high performance HVAC systems Musk has also questioned the wisdom of home air conditioner systems that make pure, fresh water Musk has also questioned the wisdom of home air conditioner systems that make pure, fresh water and then dump it on the ground. The HVAC market has had its share of innovation in recent years, as today’s more energy-efficient, quieter and better-performing systems can attest. Smart thermostats, climate control systems There has also been lots of development in the area of smart thermostats and climate control systems, with the results approximating what Musk envisions achieving with communications between his smart vehicles and smart home systems. But is it time to rethink the technologies again? There is certainly opportunity in the market for any systems that provide better, more sustainable performance, no matter where the ideas originate. Given Musk’s success envisioning a future of electric cars and lower-cost space travel (among other ideas), his thoughts on the future of the HVAC market are at least worth considering.
Google’s Nest smart thermostat is testing a new capability that will alert homeowners of problems with the operation of their HVAC systems based on artificial intelligence (AI) algorithms that analyze system performance. The technology will empower Nest Learning thermostats to provide ‘early warning’ of HVAC problems and even direct homeowners to a repair company. The new capability will involve measuring factors such as how long it takes to heat or cool a room. If the required amount of time changes, it likely reflects an underlying problem with a system’s operation. And because the system ‘learns,’ the analytics capabilities will improve over time as the system becomes more familiar with operational norms of a home HVAC system. Providing early warning Signing up for the report is easily performed through the Nest app in the ‘settings’ section Homeowners are notified by email of a suspected problem. To take advantage of the capability, Nest customers must sign up for the monthly Nest Home Report, which is an email that includes metrics on monthly power usage and ‘safety events.’ Signing up for the report is easily performed through the Nest app in the ‘settings’ section. Anyone who doesn’t want the HVAC alerts can opt-out and still receive the monthly report. In addition to providing early warning of problems, Nest is partnering with Handy, an online repair service, to direct users to HVAC professionals who can help diagnose and repair any heating or cooling problem. Handy is a ‘gig’ marketplace platform for connecting individuals in search of household services with pre-screened independent service professionals, including HVAC specialists. Nest will take note of the changes, whether related to a cooling or heating system, usually before the homeowner could notice the variations Independent service professionals There is a ‘seamless’ 60-second booking process, secure payment and a satisfaction guarantee. HVAC providers can register as a Handy Professional at the Handy website. Handy is not an employer but specializes in connecting independent service professionals with customers. During an initial test period, Nest users in 20 U.S. cities will have the ability to book a technician through the alert system, including Atlanta, Boston, Denver, Las Vegas and San Diego. The capability will be made available in additional cities across the United States over time. Alternatively, a homeowner could show the information from a Nest alert to their own HVAC technician or book through another service. According to Google, the new feature will send email alerts if ‘the Nest thermostat detects unusual or unexpected patterns,’ based on the thermostat’s historical data and current weather. Providing advance notification The alert system would be unlikely to provide advance notification if a major component were about the fail Nest will take note of the changes, whether related to a cooling or heating system, usually before the homeowner could notice the variations. Although the option can provide useful alerts to undiagnosed problems, Google emphasizes that it should not be used as a substitute for periodic checkups by HVAC professionals. Furthermore, the alert system would be unlikely to provide advance notification if a major component were about the fail. However, regular maintenance checks would ensure advance notification of any component on the verge of failure. Also, customers might not need to notify a professional of a problem, for example, if they know of an explanation for the changes, such as a door left open. The ‘early warning’ alerts are an additional feature of the smart Nest Learning Thermostat, which can save up to 12% on heating bills and 15% on cooling bills. It can also create a schedule based on comfort preferences and energy usage targets. The anomaly detection alerts are a natural extension of Nest’s predictive capabilities.
HVAC industry employees are included among “Essential Critical Infrastructure Workers During the COVID-19 Response” as designated by the U.S. Department of Homeland Security (DHS). The guidance memorandum states: “If you work in a critical infrastructure industry, as defined by the Department of Homeland Security … you have a special responsibility to maintain your normal work schedule.” The edict comes from the DHS Cybersecurity & Infrastructure Security Agency, whose goal is to provide a listing of essential workers to help state and local officials as they work to protect their communities. The list also seeks to inform critical infrastructure community decision-making to determine the sectors, sub-sectors, segments, or critical functions that should continue normal operations, appropriately modified to account for Centers for Disease Control (CDC) workforce and customer protection guidance. Business As Usual For HVAC Employees HVAC industry employees are included among “Essential Critical Infrastructure Workers During the COVID-19 ResponseSeveral sections of the March 19 document are relevant to the HVAC marketplace.

With the rise of veganism showing no signs of slowing down, plant-based meal provider, allplants decided to consolidate its seven sites into a single, central facility. When the contracting company, Forma London was presented with the challenge of sustainably fitting out the new building, it turned to Elta Fans to deliver an efficient ventilation solution. Vegan diets are becoming increasingly popular for a variety of different reasons, including health, climate change, and animal welfare. As plant-based diets become mainstream, there is a growing need for convenient, meat-free meals, and offering greater choice for consumers. Sustainable building solutions allplants set out to meet this demand, making delicious frozen meals and delivering them straight to customers’ doors. Its success derives from the passion of its two founders, JP and Alex, and has necessitated the consolidation of its multiple sites into one central facility. The new premises provided allplants the opportunity to fit out the building with sustainability at its core Moving to new premises provided allplants with the opportunity to fit out the building with sustainability at its core. All the desks, for example, are made from locally sourced, sustainable wood, but it was in the kitchen that the greatest challenge was posed. Forma London, a principal contractor based in the capital, was tasked with delivering the project. Combining construction expertise with eco and ethical credentials, the contractors began working on providing ventilation for the meal provider’s centerpiece, the development kitchen. Enhanced ventilation The kitchen is where the magic happens, allowing allplants to ensure the meals it produces are as tasty as possible. As specialists in microwavable food, the traditional ventilation set-up of a commercial kitchen was far greater than what the site needed. Anthony Afram, Building Services Manager at Forma London, said “Balancing energy efficiency with performance output is a priority in any project, but given the nature of the client, this took on a whole new level of importance.” He adds, “The challenge of equipping the kitchen with the right ventilation was highlighted by the two bifurcated axial fans that we were originally quoted. These would have been perfect for a busy commercial kitchen, but for this application they were overkill. In terms of expense and performance, they would have been much more than required, and ultimately incurred far higher running costs than necessary.” Energy-efficient ventilation systems It isn’t just for the purposes of corporate social responsibility or an altruistic mindset that businesses must pay close attention to the energy credentials of their ventilation systems. Building Regulations and Ecodesign Directives obligate everyone in the supply chain, from manufacturer through to contractor, to select and supply ventilation with maximum levels of efficiency. This means that most commercial and industrial fans need to be provided with functionality that allows control over fan speed and power. Skyflow SSRL EC axial roof fans For allplant’s kitchen, this meant specifying a fan that was appropriate for a busy, but pollutant-low kitchen In the context of allplant’s kitchen, this meant specifying a fan that was appropriate for a busy, but pollutant-low kitchen. Owing to its position as the first ErP compliant low silhouette axial roof fan on the market, the decision was made to turn to Elta Fans’ Skyflow SSRL EC. Equipped with an EC motor with an integral potentiometer commissioning device as standard, the fan is ideal for environments such as a light commercial kitchen. Intuitive controls Anthony continues, “For applications such as this, where ventilation requirements may be variable, the ability to control fan speed through intuitive controls is vital. “It also highlights the importance of not over-specifying, as it can be all too easy to opt for the highest performance available, without consideration of the energy expenditure. “Elta Fans’ Skyflow SSRL is a great example of the energy saving possibilities associated with the latest ventilation technology. Opting for the most efficient products can make a significant contribution to the overall energy credentials of a building, and projects such as this illustrate what is possible.” Energy savings and sustainable HVAC system allplants is understandably concerned with sustainability, and the fitting out of its premises necessarily reflects this. However, it is important to be aware that its growth as a company shows the overall trend towards an environmentally-conscious society. As legislation is introduced to reflect this, those tasked with providing ventilation must ensure they opt for solutions that balance performance with optimum energy efficiency.
The task facing Donovan & Son’s, Inc., Plumbing/HVAC in Middletown, RI was to propose and install heating system boilers that allow the Preservation Society of Newport County to conserve on fuel costs, more closely match varying building heat loads, and coexist with the tremendously large water content of a gravity system. The historic mansions of Newport, RI are known for their elegance and remind its visitors of a bygone era of social and financial preeminence during the turn of the twentieth century in America. Cornelius Vanderbilt II, grandson of railroad industrialist Cornelius Vanderbilt (1794-1877) had the 70 room Italian renaissance inspired mansion built on the site of a wood-framed house which was destroyed by fire in 1892. gravity feed system The Breakers is now owned and operated by the Preservation Society of Newport County A year later, Architect Richard Morris Hunt, deployed an international team of craftsmen and artisans to create the mansion, which is considered to be the most elegant of the Newport summer cottages. The Breakers is now owned and operated by the Preservation Society of Newport County. The preservation society recently replaced an old inefficient boiler with two high efficiency model MPC9 boilers (up to 88.6% efficiency). The old boiler operated at minimal efficiency, especially during the spring and fall when the building demand only required partial load. The mansion, built during the dawn of electricity, used a gravity feed system with large 18-inch supply and return mains. This large supply and return mains divide up into a network of several smaller mains that feed scores of cast iron radiators hidden away in the walls of the structure. heat distribution system The radiation that heats The Breakers is built into the walls of the building and is for the most part out of sight. The heat distribution system consists of radiators lying horizontally in vertical structural chase ways throughout the building. Air connects upwards through these chase way-mounted radiators and is distributed into the rooms via ornately cut grilles in the marble walls allowing the system to exist without being seen. The task facing Donovan & Son’s, Inc., Plumbing/HVAC in Middletown, RI was to propose and install heating system boilers that allow the Preservation Society of Newport County to conserve on fuel costs, more closely match varying building heat loads, and coexist with the tremendously large water content of a gravity system. The boilers had to be installed as part of a century old high-mass gravity feed system. system injection piping MPC boilers have built-in return water temperature protection in the form of a return water mixing tube (RWMT) To do this, Donovan & Son’s converted the near boiler piping to a primary/secondary configuration consisting of a boiler room loop with boiler and system injection piping. The purpose of the boiler room loop was to create a buffer area where heated water from the boilers is no longer in direct contact with the cooler system return water as each boiler injects its heated water into the boiler room loop and in turn heated water from the boiler room loop is transferred into 18-inch supply and return mains, utilizing several small pumped connections. desired minimum temperature This configuration assists the flow of the gravity system to operate as it always has, by simply keeping the large system supply main hot and the boiler loop well above a desired minimum temperature. Such a large water volume in the system loop required that added consideration be given to boiler protection. MPC boilers have built-in return water temperature protection in the form of a return water mixing tube (RWMT). The RWMT protects the boiler from low return temperatures by distributing cool return water evenly throughout the length of the boiler, virtually eliminating concerns of thermal shock and providing balanced flow through each casting. Operating parameters for the MPC, with the RWMT, require a minimum 130ºF supply temperature, minimum 80ºF return temperature and a maximum of 80ºF ∆T. modulate supply water temperature Modular boiler systems provide redundancy if a mechanical device fails to operate during the winter months System operation is controlled by a Tekmar 264 boiler staging control allowing for two individual sets of high-low firing, or four stages of firing. The control also modulates supply water temperature based on outdoor air temperature fluctuations. Domestic hot water is generated using a Burnham Alliance indirect water heater which replaced a separate oil fired water heater. Staging the boilers, modulating the system set-point based on outdoor air temperature and installing the indirect water heater, all combined with the MPC’s high-efficient three-pass sectional design are key factors in reducing energy costs. A recent jobsite visit showed the outdoor temperature to be 38°F and the system water temperature at 155°F with one boiler sustaining the load on low fire. greatly reduced fuel costs The ultimate benefits of The Breakers’ new boiler system will be greatly reduced fuel costs and greater building comfort, by more closely matching the building heat load. Additionally, modular boiler systems provide redundancy if a mechanical device fails to operate during the winter months. The building can now be heated with as low as 25% of the total boiler capacity on the plentiful amount of moderate days that we encounter during the heating season. This will be a boiler system that will offer considerable payback for many years to come.

Two new Burnham model MPC™ high efficiency commercial boilers were recently installed by The Witmer Company of New Holland, PA in the historic ‘High Point’ Mansion located in Hershey, PA. The Model MPC boilers will provide space heating for the 22-room Mansion which was built in 1908 as the home of Milton and Catherine Hershey. Mr. Hershey was the founder of the Hershey Chocolate Company, now known as The Hershey Company. Today, ‘High Point’ Mansion serves as the headquarters location for the Hershey Trust Company which, among other things, oversees the continued philanthropic efforts that were founded by Milton Hershey. Exceptional heat transfer Two, five-section model MPC boilers were selected to provide heat for the building through a combination of 5 air handlers, 52 fan coils and commercial finned tube radiation. The MPC’s are well suited for the job with their unique 3-pass flue design and Return Water Mixing Tube, which translates into exceptional heat transfer as well as the ability to accept return water temperatures as low as 80°F. The MPC’s 4-inch insulation blanket insulates the boilers so well that the jackets stay cool to the touch The MPC’s are manufactured in nearby Lancaster, PA using BC25-HSi cast iron sections, which contain high levels of silicon for exceptional flexibility and heat transfer capabilities. Even at start-up a big difference could be noticed – the boiler room temperature had dropped 30-degrees from the previous boilers. The MPC’s 4-inch insulation blanket insulates the boilers so well that the jackets stay cool to the touch, and the boiler room at the Hershey Mansion is now a much more comfortable place to work. Heat distribution systems Heat transfer and high efficiency is only part of the equation in this new installation, with a variety of heat distribution systems and controls the MPC’s needed to integrate with an advanced control system. The power burners were ordered with the powerful new Burnham SBC™ – or Sage Boiler Control, which made the control portion of this job simple for the Witmer crew. The SBC’s control many of the boiler room functions such as outdoor reset, multiple boiler modulation, lead-lag boiler rotation, combustion air louvers, and pump controls, all without the need for additional control systems. And the SBC’s tie right into the existing building management system so the whole system works together to deliver comfortable, efficient heat throughout the beautiful historic Hershey Mansion.

The Hawaiian Islands have a lot to offer – pristine beaches, natural beauty and friendly citizens. And now, with the help of Ruskin and its partner contractors, it also has a state-of-the-art middle school campus. In order to accommodate the continued growth of Kapolei, the Kapolei School District recently constructed a new middle school campus. Located on Hawaii’s most populated island, Oahu, the new Kapolei Middle School is a perfect example of how new architecture can be used to enhance and serve the community. “Our new school is designed to educate up to 1,600 students with multi-track schedules ensuring the community may continue to grow,” says Annette Nishikawa, Principal at the school. “We are pleased with our new facilities.” Protecting ventilation openings Working with a local architect, Mitsunaga & Associates, Inc., the district developed a design that includes Ruskin’s ELF520DD rain resistant and sight proof louvers. Located in the block wall and metal roofed structures of the administration, classroom and cultural center buildings, these louvers serve a dual purpose – to protect the ventilation openings against environmental elements and enhance the exterior of the campus buildings. Additional Ruskin louvers were used to protect the ground level openings of the unit ventilators for each classroom The design team used the horizontal lines of the louvers to highlight the canopy on the entrance of the cultural center and accent the gables on several buildings. Additional Ruskin louvers were used to protect the ground level openings of the unit ventilators for each classroom. The general contractor, Albert C. Kobayashi, Inc., coordinated construction of the campus. Building roofing and louver systems The building roofing and louver systems were installed by Quality Sheet Metal & Air Conditioning Company Limited. The project challenged Ruskin’s design and manufacturing team with a number of unique shapes and angles. To successfully meet the specifications, the ELF520DD louvers were precision fabricated to ensure it would fit each of the openings. “Ruskin’s attention to detail resulted in a seamless installation,” reports Roy Kawakami Jr. of Quality S/M & A/C Co. Ltd. Coordinating the louver portion of the project, Ruskin’s representative, Norman Wright Mechanical Equipment Corporation, Inc., worked closely with Quality S/M ensuring the quantities, sizes and types of louvers were correct. “The various shapes and changing opening dimensions as this project developed, kept us on our toes,” says Curtis Kenmostu, Norman Wright’s Hawaii Manager. “Ruskin’s timely response and complete and accurate CAD drawings eliminated potential installation problems.” Highly weather-Resistant Located on Hawaii’s Oahu Island, Kapolei Middle School was designed to blend with the natural beauty of the Pacific islands. When the school district expanded their middle school facilities, they chose the Ruskin ELF520DD rain resistant and sight proof louvers. Custom built to Hawaii’s ‘Second City’ district specifications, these specialty louvers are in a class of their own. In addition to being sight proof, they also protect ventilation opening from water penetration In addition to being sight proof, they also protect ventilation opening from water penetration. Coated with a highly weather-resistant KYNAR finish, these louvers enhance the school’s appearance and will give the school years of exceptional, maintenance-free service. To help create an island oasis for the students and faculty, exterior finishes and colors were chosen to complement the architecture of the neighborhood. Providing quality products “Ruskin’s computer matching automated finishing system eliminated the need for field finishing the louvers,” says Curtis. “All of the louvers include a 20-year warranted factory applied Kynar finish.” Protection of any HVAC openings in buildings challenges the architect for functionality and appearance. The Kapolei Middle School project is just one example of Ruskin’s commitment to meeting these challenges by providing quality products and excellent service. Ruskin continues to research new louver solutions like the recently released models to resist wind driven rain and hurricane force winds. With both horizontal and vertical blade louver designs, Ruskin louvers will enhance the exterior appearance of one's building without compromising performance. With more than 40 years of experience designing, testing and manufacturing louvers, Ruskin knows what it takes to deliver “real” solutions for current louver applications.
