Chilled Water Data Room Units

High-efficiency Cooling for Data Rooms — 79-220 kW (downflow), 66-206 kW (upflow), 85-525 kW (custom)

High-efficiency Data Room Units (DRU) are designed for high-density load areas where a large cooling duty is required from a compact footprint and to provide the reliability and redundancy required for data center cooling. Our data room units utilize FANWALL TECHNOLOGY® to provide even, efficient air supply and redundancy. Alternatively, the units can be fitted with speed controllable, electronically commutated (EC) fan/motor assemblies or ultra-high efficiency Permanent Magnet Motors.

Flexible options, including a range of sizes and cooling capacities, filter options, customized coils, and fully programmable controllers, mean you’ll get the perfect cooling solution for your data room.

Benefits & Features

Superior Energy Efficiency
  • FANWALL TECHNOLOGY features fans, motors, and controls that can achieve 7-9% higher efficiency than other fans in their size range.
  • Permanent magnet motors, which are typically 7% to 15% more efficient compared to NEMA Premium™ efficiency induction motors.
  • Custom heating and cooling water coils are designed and constructed for optimized efficiency in demanding applications.
Design Flexibility
  • Standard 79-220 kW (downflow) and 66-206 kW (upflow) cooling capacities. Custom 85-525 kW units are also available, providing flexibility to reduce the number of units, electrical and piping requirements, and indoor footprint devoted to computer room cooling.
  • Custom designed heating and cooling water coils in a range of sizes to meet your application requirements.
  • PerfectPleat 2” and 4” prefilters available in the optional filter section. Both sizes (Standard and High Capacity) are rated MERV 7 or MERV 8.
Industrial-grade Construction and Design
  • Optimized chilled water coil with low air and waterside pressure drop.
  • Longer filter life and reduced pressure drop due to larger filter area.
  • More efficient direct-drive fans with higher static pressure capability than EC fans.
  • Improved uniformity of airflow over coils and in velocity from plenum.
Unit Controller Options
  • Unit fitted with a fully programmable direct digital controller (DDC) or industrial PLC controller complete with touch screen display/user interface.
  • Options available for BMS interface via Modbus®, LonWorks® and BACnet® communications.
  • Controller monitors temperature and relative humidity and activates cooling humidification or dehumidification to provide precise and efficient conditioning of the supply air.
  • Multiple units can be networked together to provide group or run/standby control.
