Nortek™ Air Solutions introduces the CDU1200, a 1,200-kW coolant distribution unit (CDU) that’s the single most powerful, compact CDU on the planet, and the newest addition to its ServerCool™ data center liquid cooling product line. The CDU1200’s small 58 (d) x 35 (w)-inch (1,475 x 900-mm) footprint supplies an industry-first 1.2-MW of cooling capacity in a density of 14.6-ft2 (1.3-m2) that helps attain optimum power usage effectiveness (PUE). The CDU1200 is a perfect new construction or retrofit liquid cooling solution for high performance computing (HPC) and enterprise data centers, as well co-location, corporate network edge, government, research and other data center formats. Superior Pumping Power In an age where liquid cooling is required to support growing chip power densities, the CDU1200’s kW/ft2 capacity is unrivaled when directly compared to competitor products. The CDU1200’s compatibility with existing ServerCool CDU’s, such as the CD6 300-kW floor mount and the CD5 50-kW rack-mount, enables modular growth of existing systems. The CDU1200’s superior pumping power also allows it to be placed outside of the white space. The CDU1200 offers two redundant 15-hp stainless steel pumps with many energy-efficient features The CDU1200’s highly-efficient heat exchanger technology thermally transfers primary loop cooling to the secondary loop’s liquid cooling circuit for distribution to IT rack cold plates. The CDU1200 offers two redundant 15-hp stainless steel pumps with many energy-efficient features including electronically-commutated (EC) motors and variable frequency inverters that efficiently modulate optimum performance flow rates for the system’s 320-gpm (1,211-L/m) capacity. Liquid Cooling Control Experience System water purity is optimized with a standard 50-micron washable ultra filter/strainer and an optional ultraviolet (UV) light biological contaminant sterilization system. The CDU1200 has an onboard programmable logic controller (PLC)-based microprocessor using custom-written, proprietary software based on ServerCool’s decades of liquid cooling control experience. The unit’s control infrastructure features compatibility and plug-and-play connections with Modbus The system’s full instrumentation of triple-redundant pressure transducers and temperature sensors offer unprecedented pinpoint control and monitoring of vital statistics, such as primary and secondary loop discharge/return temperatures, data hall temperature and humidity, pump PSI and many other critical parameters. Operation parameters are accessed from the CDU1200’s user-friendly, seven-inch (17-cm) color LED touchscreen HMI or a remote monitor. The unit’s control infrastructure features compatibility and plug-and-play connections with Modbus, BACnet™ and other building automation system (BAS) protocols. Computer-Automated Testing System The CDU1200 has a narrow Delta-T temperature which helps facilitate eligibility for the Green500 supercomputers list. It’s rated nominally with a 90°F (32°C) primary and a 7.2°F (4°C) approach Delta-T and exceeds 2.5-MW capacity with an approach of 14.4°F (8°C). Nortek’s commitment to the CDU1200’s quality control and short lead times is illustrated by a newly-built state-of-the-art, dedicated production line established at Nortek Global HVAC’s world-class 350,000-square-foot (32,516-m2) Dyersburg, Tennessee., manufacturing facility. The Demand Flow Technology-certified plant uses quality control and reliability processes, such as multiple checkpoints each with the unit’s CAD drawings on a computer monitor. A 100-percent computer-automated testing system prevents human error. Dripless Smart Connector Accessories The CDU1200 design also includes: Requires less life space than a CRAC when converting a data center to higher cooling and higher density liquid cooling; Robotically welded, corrosion-resistant ASIS 316 stainless steel is used instead of some competitors’ plastic piping that potentially melts or leaks easily under higher pressures. Piping infrastructure is subjected to a stringent series of factory pressure and hydraulic quality control testing; Maintenance is minimal and requires only periodic filter/strainer checks; Modulating actuator valve can control dew point and prevent condensation; Compatible with all brands of chillers, evaporative coolers, cooling towers and other chilled water central plant formats; User-definable LED alarms for leak detection/prevention and performance criteria; Fixed flow meters on primary and secondary circuits; Two-year standard warranty–one of the industry’s longest; Optional manifolds and dripless smart connector accessories fit all cold plate piping configurations. ServerCool products are ISO-9001:2015-certified and backed by Nortek’s proven 20 years of mission critical experience, design and customer support.
From April 2019, Humidity Solutions based in Leatherhead will be sole UK distributor for the Vapac range of electrode boiler steam humidifiers. The knowledge and expertise of both companies combine to enable Vapac humidifiers to be offered to the market with a full package of support services. These include: Stock availability of standard units, consumables and spares Free design, site surveys and quotations Technical telephone support Servicing and maintenance Training and familiarization courses at the Leatherhead facility Nortek Global HVAC are confident that their partnership with Humidity Solutions will provide an even better customer service experience.
From February 2018, HVAC brands, Ambirad, Airbloc, Benson, and Reznor will be brought together under a single brand: Reznor. Each of these brands forms part of Nortek Global HVAC UK Ltd, and by combining their respective offerings, the business simplifies the customer experience by providing a single point of contact for all HVAC solutions. The HVAC brand transition coincides with a number of new product developments, and a portfolio that is now fully compliant with the Energy related Products (ErP) regulations. Delivering Superior Customer Experience Simon Parker, President and General Manager of Nortek Global HVAC UK Ltd’s Light Commercial Division heads up the Reznor brand in the UK and beyond. He comments: “We want to better serve our customers. By offering a diverse but cohesive portfolio, we can offer clarity for our customers by taking out complexity and portfolio duplications.” By unifying under the Reznor brand, we can commit to meeting our customers’ expectations" “We are focused on becoming a solution provider, rather than just a product supplier. By unifying under the Reznor brand, we can commit to meeting our customers’ expectations, delivering a superior customer experience, and building upon Reznor to become the preferred HVAC brand.” “The move to Reznor has been addressed with great care so that we do not create disruption,” explains Parker. “Existing warranties and maintenance contracts in the other brand names will be honored. Our customers will be notified about our strategic intent and how that will affect them. We believe it’s a positive move for all concerned.” ErP Compliant Product Offering With one dominant brand under Reznor, the company is looking to create economies of scale and to invest further in R&D to keep new products coming to market, as well as improving on customer service. Andrew Field will be Reznor’s dedicated National Sales Manager for the UK. He will lead a team of area sales and business development managers. Parker adds that specifying and buying Reznor products will be made easier with an updated online presence: “Moving from a multiple brand setting to a single leading brand for UK will be reflected into our online presence. We want to make it easier to do business with us, so we opted for a ‘pre-sales’ portal and a complimentary ‘post-sales’ portal to fully serve our site visitors. Both portals will reflect our renewed proposition, be fully up-to-date on our 2018 ErP compliant product offering, and be easily accessible via mobile technology.”
