Nortek Air Solutions has introduced 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. 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’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. It also 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.
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 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.
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).
