The YORK® Mission Critical Direct Evaporative Cooling (DEC) AHUs from Johnson Controls are designed to meet the specific needs for data centers. The units are offered in two sizes (250 kW and 500 kW) and in perimeter and rooftop configurations. The company says the YORK Mission Critical DEC units yield an ultra-efficient partial-power usage effectiveness (pPUE) of less than 1.1.
The AHUs are designed to meet phased data center expansion strategies. Optional direct expansion (DX) or chilled water cooling (CWC) coils allow for installation in diverse geographic locations while maintaining a low initial investment. Other design features include a compact footprint, intelligent factory preconfigured controls, commissioning via smart device, staged control to optimize water utilization, front-loading filters, and more.
