The RLM Xtreme System from UV Resources offers installing contractors all of the UV-C lamp performance, monitoring and safety components in a single order. The multiple-SKU RLM Xtreme System streamlines ordering and provides facility managers and HVAC contractors with all of the elements necessary to install a comprehensive HVACR efficiency solution.

HVACR equipment

Designed for mid-to-large volume HVACR equipment, the Remote Lamp Mount (RLM) germicidal system offers the industry’s highest UV-C fluence (dosage) and is now available with four of the most popular fixturing components, including:

  • Integrated plug-and-play remote ballast,
  • Prewired 12V access door safety controller (required for UL 1995-compliance),
  • Lamp framing supports, and
  • Operation monitoring capability.

Ultraviolet irradiation levels

The system’s 360-degree high-output lamp generates up to twice the ultraviolet irradiation levels to kill and/or degrade the toughest microorganisms and organic matter, whether on a surface or airborne. Applying ultraviolet germicidal irradiation (UV-C) lamps downstream of HVACR cooling coils has been shown to improve IAQ, boost airflow and maximize heat-exchange efficiency, which can reduce energy use by up to 25 percent.

The RLM Xtreme System allows installers to easily overlap multiple lamps in scissor-like fashion offering unlimited lamp configurations by using one or two standard lamp lengths, rather than being constrained by installing fixtures end-to-end. Its LampHolder with LampClamp™ allows lamps to “slip-in” and click in place, while being held securely with a Lamp Compression Nut. 

The prewired plug-and-play controller automatically de-energizes the UV-C system

  • Integrated Plug-and-Play Remote Ballast - The UL-Listed, 120-277 volt power supply can be mounted up to 20-feet away from the lamp using a flexible metal conduit-protected wiring loom. The integrated plug-and-play X-Box remote power supplies and lamps are electronically matched to provide the highest output and longest life expectancy.
  • Prewired Safety Controller - The prewired 12V access door controller regulates up to six safety interlock switches/access door sensors via low-voltage connections (one is included with every X-Box). This new feature cuts installation time of the RLM Xtreme System by up to 50 percent.
    The prewired plug-and-play controller automatically de-energizes the UV-C system when any HVACR access point is opened, conforming with UL 1995 requirements. Prior to the prewired system, contractors would have to individually install 120-277V safety switches for each access point via conduit, increasing labor costs.
  • Lamp Framing Supports - Designed to speed installs, framing kits include all components needed to install UV lamp fixtures in an air handler plenum, including two ~60-inch, extruded aluminum vertical supports, ceiling gusset, levelling feet and all the hardware necessary for installation. The framing supports can accommodate multiple UV-C lamps and the vertical supports can be easily “spliced” together to accommodate larger plenums up to ~120-inches tall or cut on-site for smaller applications.
  • Electronic System Monitoring - The CU2™ lamp/power supply monitor provides a local visual indicator of each lamp/power supply’s functionality via green LED indicator lights. Additionally, each CU2 provides a 0-5V analog signal sent to building automation/ management systems.
    Operation of up to eight lamp and ballast combinations can be monitored for each AHU, and multiple CU2 monitors can be linked together in a daisy-chain sequence to verify as many individual UV-C fixtures as necessary. Likewise, multiple CU2 signals can be combined into one signal for output to a BMS using the UVRepeat™ accessory (not included).

Commercial or industrial HVACR environments

UV-C energy penetrates deep into the HVAC coil eliminating performance-robbing and odor-causing microbial build-up that can’t be reached by pressure washing or chemical treatment. In new HVACR equipment, the 254nm germicidal wavelength keeps cooling coil surfaces, drain pans, air filters, and ducts free from organic build up to maintain original heat-transfer efficiency capacity, airflow and IAQ.

The RLM Xtreme housing can be mounted up to 20-feet away from the lamp

In retrofit applications, UV-C eradicates accumulated organic matter and then prevents it from returning. This trifecta of boosting capacity, saving energy and lowering maintenance is driving more than nine-of-every-ten UV-C installations today. All of these system-enhancing efficiencies are discussed in greater depth in ASHRAE’s 2019 Handbook of HVAC Applications, Chapter 62.

Easily Configurable

The RLM Xtreme housing can be mounted up to 20-feet away from the lamp making the complete install simple, quick and near fail-safe. Lamp holding and locating mechanisms simplify lamp positioning and securing.

With its highly efficient power supplies, powder-coated galvanized steel construction, the RLM Xtreme system can withstand the harshest commercial or industrial HVACR environments. Ideal for new or retrofit applications, the system can reduce system maintenance costs and downtime, energy use and airborne levels of noxious and infectious microorganisms, thus helping to improve overall indoor air quality.

HVAC Companies in the News as Cold Weather Pummels United States
HVAC Companies in the News as Cold Weather Pummels United States

Deadly cold weather recently made headlines in Texas, where wintry conditions knocked out power to around 4.5 million homes at one point. Power outages, combined with freezing conditions, sent Texans scrambling for home heating alternatives, such as generators and fireplaces, and to seek shelter in powered warming centers or businesses. Some resorted to living in running cars. Snow, ice and extreme cold have been widespread this year in the Mid-Atlantic and Northeast United States, too. At one point, 78 million Americans were under a winter weather alert, and more than 27 million were under a hard-freeze warning. More than 2,500 new records were set for lowest high temperatures. At least 38 people nationwide died from winter storms or frigid conditions. Additional Challenges for HVAC Industry For HVAC companies, the cold weather means more business, and additional challenges to serve their customers' needs. Local TV stations often turn to HVAC installers to provide commentary and insights about their surge in business brought on by Mother Nature.Sub-zero weather translated into below-freezing indoor temperatures for some HVAC customers In Lincoln, Neb., for example, sub-zero weather translated into below-freezing indoor temperatures for some HVAC customers whose furnaces were not running. Many of the systems had been badly maintained, operated inefficiently, and/or were beyond their life expectancy. “We’ve had some guys that have houses that their furnaces aren’t running, we’ve had some houses at 31 degrees, 34 degrees,” said John Henry’s HVAC Service Technician, Thaddeus Bertsch, interviewed by 10/11 KOLN News. Issues with Frozen Pipes "As [cold weather] goes on, we are starting to get more calls for frozen pipes," adds Keith Jackson with Jackson Plumbing, Heating, and Cooling, Decatur, Ala. "People have no water," he told WZDX Fox News. HVAC technicians stay extra busy working in the snow and dropping temperaturesAlso, outdoor heating and AC units were shutting down. The units were freezing up, and frozen rain and ice affected the operation of the outside condensers. The company had crews out trying to help people with frozen pipes across Decatur and beyond. HVAC technicians stay extra busy working in the snow and dropping temperatures. For instance, business tripled for Jarboe’s Heating, Plumbing and Cooling in Louisville, Ky. Field technicians were working longer hours because of heaters going out, reported WDRB News in Louisville. "As soon as the phones are open, they’re ringing" For two days in February, by nine o’clock in the morning, J.E. Shekell Inc. in Evanstan, Ind., already had received over 30 service calls. "As soon as the phones are open, they’re ringing,” said Jim Poag of J.E. Shekell Inc. A report by WFIE 14 News in EvanstanFrigid temperatures cause furnaces to work extra hard to keep houses warm highlighted how frigid temperatures cause furnaces to work extra hard to keep houses warm. Depending on how well they are maintained, and how old the machine is, it can sometimes be too much. “We’ve been getting a lot of calls, several, you lose count after a while, just trying to help as many people as we can right now. It’s probably about my seventh call of the day so, we’re out trying to help as many people as we can,” said John Hambleton of Lyerla Heating & Air, Joplin, Mo. Dangerous temperatures and winds Lyerla Heating and Air received 300 service calls in just two days on Feb. 15-16. Like many of the local media reports, KSN News in Wichita, Kan., emphasized the need to prevent untimely breakdowns by getting units serviced before dangerous temperatures and wind chills set in. Staff at Wiersgalla Plumbing & Heating, Eau Claire, Wis., says service calls had risen roughly 25% when the cold rolled in. Staff worked extended hours to fix broken heaters and frozen home exhausts. "Over the last week and a half, we've experienced an increase in calls obviously because of the cold," said Christina Wiersgalla, VP of operations for Wiersgalla Plumbing & Heating, Eau Claire, Wis., in a report by WQOW 18 News. Among the consequences of brutal winter weather are a greater appreciation of the work of HVAC companies and an opportunity to shine a spotlight on how they keep customers comfortable in their homes and businesses.

Lessons From The Past: The Value Of Ventilation In A Pandemic
Lessons From The Past: The Value Of Ventilation In A Pandemic

If history truly repeats itself, might we learn lessons from the past – even lessons about managing a novel coronavirus that upends our way of life and changes the world forever? The most commonly cited parallel to the COVID-19 pandemic is the Spanish flu pandemic of 1918. Both diseases are caused by viruses that had not been seen before. In both cases, no one had immunity to a highly infectious germ that was spread through respiratory droplets. Both outbreaks occurred in multiple waves over several years. Furthermore, in both cases, it became clear that ventilation, fresh air, open spaces and sunlight are useful factors in promoting good health. Fresh Air Movement During the time of the Spanish flu, there were signs posted in buses and throughout New York that advised: "Keep your bedroom windows open [to] prevent influenza, pneumonia [and] tuberculosis." There was even a national campaign known as the “Fresh Air Movement,” calling for people to be outside more, and urging greater ventilation indoors. The movement included a kind of traveling show that spread the word about the “national poison,” which was the result of people breathing stale air inside closed rooms. These concerns predated by decades our enthusiasm for “indoor air quality.” In became common after 1918 to position radiators providing steam heat under open windows to combine warmth with fresh air, even on the coldest of days.   The Open-Air Treatment of Pandemic Influenza It was also common practice by 1918 to place the sick outside in tents or in specially designed open wards But the advantages of fresh air go back even further, as described in a 2009 article in the American Journal of Public Health (AJPH) titled “The Open-Air Treatment of Pandemic Influenza.” During the 1918 pandemic, as today, many cities banned public assembly, closed schools, isolated those infected and mandated the wearing of face masks. It was also common practice by 1918 to place the sick outside in tents or in specially designed open wards, according to the AJPH article. The practice dates back to English physician John Coakley Lettsom (1744-1815), who was among the first advocates of the “open-air method.” The 1800s saw emergence of tuberculosis sanitoriums, which treated the lung disease with a combination of fresh air, gentle exercise in the open, nutrition, and a minimum of medicines. Lack of ventilation Spending time in well-ventilated houses in the country became seen as superior to patients being confined to warm, badly ventilated rooms to protect them from the supposedly harmful effects of cold air. Lack of ventilation forced patients to breathe foul air, contaminated with germs, over and over. Research later confirmed the importance of measures to prevent influenza virus from spreading through buildings. Improvements in air-handling equipment, portable filtration units, and introduction of physical barriers and other partitions or doors also provided protection. These lessons were clear long before the advent of the novel coronavirus that causes COVID-19. Their successful deployment during the pandemic have further supported their value. importance of HVAC Although the COVID-19 pandemic caught the world off-guard, there were plenty of historical precedents However, lockdowns during the pandemic have also tended to keep the population closed up in buildings, sometimes with less-than-adequate ventilation and access to fresh air. In retrospect, some of those decisions seem regrettable.  Although the COVID-19 pandemic caught the world off-guard, there were plenty of historical precedents. Copious research over the years supported the best approaches to stemming the spread of the virus, although it took time for historical insights to work their way into the general practice implemented in the current pandemic. There is also historical precedent for the importance of HVAC in the current pandemic. Ventilation and fresh air have become higher priorities, as has the HVAC market’s role in providing a safer indoor climate with minimal disease spread.

Change Environments Not Behaviors: How Active Air Filtration Can Help the UK Come Out of Lockdown Long-Term
Change Environments Not Behaviors: How Active Air Filtration Can Help the UK Come Out of Lockdown Long-Term

According to the latest statistics, Britain now has the highest daily COVID-19 death rate in the World, following an unfortunate record month of fatalities during January 2021. While UK Government is quick to defend this statistic, the fact remains that our country has been crippled by the SARS-CoV-2 virus, and now, as the population battles through yet another lockdown, it seems that the only 'way out’ is through widespread vaccination. impact of COVID-19 Though imperative, this strategy emphasizes the real challenge that Governments across the globe have faced in trying to control this virus; that reducing the transmission or ‘R rate’ is reliant on the behaviors of people. People who have lived with some form of restrictions for too long, people who are frustrated and tired of the impact COVID-19 has had on their businesses, and people who have simply lost trust in Government U-turns and last-minute decisions. What’s more, despite the best efforts of millions to comply with restrictions, the virus itself is one that is hard to contain, particularly with asymptomatic cases unknowingly passing it to others in key locations like supermarkets or via public transport. Regardless of this challenge, there is a solution that doesn’t rely on changing people’s behaviors, but rather in changing the environment in which people live, work and socialize. That solution is the implementation of Active Air Purification Technology. What Is Active Air Purification Technology? Active air purification technology is effective in every cubic cm of indoor air and surface space simultaneously and continuously Most air purification technologies are passive in that they can only have any effect when the air containing the pollutant comes into close proximity or passes through the unit. Examples of this are filtration, UV-C, and various PCO and ionization technologies. In other words, certain operational conditions must be met in order for them to be effective. Active air purification technology is not limited in this way and is effective in every cubic cm of indoor air and surface space simultaneously and continuously. This means pollutants, like viruses and bacteria, are instantly treated no matter where or when in the indoor space they are emitted or exposed which is significant in the context of COVID transmission. Whether required to mitigate microbials, allergens, or dangerous gases and VOCs, active technology offers a unique solution to destroying microbials instantly, offering a safer, cleaner, and more effective approach to air purification in domestic, commercial, and industrial environments. REME Air Purification Technology REME is an active air purification technology developed and patented 15 years ago by RGF Environmental Group, a COVID critical environmental innovator and manufacturer headquartered in the United States. Using no chemicals or harmful substances, REME comprises a number of known air purification technologies and sciences in one product. Its active capability works by producing and maintaining similar concentrations of hydrogen peroxide molecules as those found in the outdoor air and combines a process of bipolar ionization. When coming into contact with microbials, the naturally occurring ionized molecules break them down, destroy them and then revert them back to harmless water vapor and oxygen. The bipolar ionization effect causes other airborne particulates to agglomerate together causing them to become larger and heavier and drop out of their air or get captured in HVAC filters. RGF’s REME air purification technology produces 1 quadrillion ionized hydrogen peroxide molecules every second, quickly and safely killing any airborne virus or bacteria, including SARS-CoV-2 on a continuous basis. Its effectiveness has been verified by nationally accredited independent labs and testing bodies in the US and by other governments in numerous tests over two decades, with results also confirming a 99%+ inactivation for highly infectious viruses and bacteria, such as H1N1 or ‘Swine Flu’, SARS, Norovirus, MRSA and Bird Flu, just to name a few. Vaccinate Environments And People Air purification technology drives down the R rate for good by effectively vaccinating the air in which the virus circulates In understanding exactly how active air purification technology works and its capability to successfully destroy COVID-19, it’s clear that it presents an opportunity to drive down the R rate for good by effectively vaccinating the air in which the virus circulates. This strategy is already working its way through the United States with leading brands, like restaurant chain TGI Friday, installing active air purification technology across all establishments and has also caught the attention of renowned insurance market, Lloyds of London, which has installed the technology across all UK offices to ensure its 5,000 plus staff members can return safely to work. Improving the environment For nearly 12 months the world has been coping with COVID-19, describing it as an ‘unprecedented period’ where there is no clear end. However, in vaccinating both people and the environment in which it lives, the virus can be controlled once and for all. Ultimately, with a crippled economy, in excess of 100,000 deaths and a generation of children impacted by the closure of schools, now is the time to accelerate response and change the environments in which the virus circulates, not just the people.
