The YORK® Mission Critical Direct Evaporative Cooling (DEC) Air Handling Units (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 YORK® Mission Critical DEC units yield an ultra-efficient partial-power usage effectiveness (pPUE) of less than 1.1. This is achieved through use of the industry’s highest media efficiency, which extends free cooling operation hours.

Unlike most DEC AHUs, YORK® Mission Critical Air Handling Units 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:

  • Compact footprint that features reduced weight and size
  • Intelligent factory pre-configured controls – no field programming required
  • Commissioning via smart device – reducing time to start up
  • Staged control to optimize water utilization
  • Front-loading filters for ease of installation and speed of maintenance
  • N+1 fan redundancy to fulfill mission critical data center demands
  • Mobile Access Portal (MAP) service tool for configuration and management via Wi-Fi®
  • Built on tested and proven YORK® air handling product platform
  • Optional Smart building hub for 24/7 remote connectivity and notification
