CyberCool CMU

Coolant Distribution Unit for seamless heat transfer in liquid cooling solutions

As the heat density of server racks continues to increase at a rapid pace, liquid cooling systems have gained widespread acceptance as an effective method of heat dissipation. The STULZ Coolant Distribution Unit CyberCool CMU is a central component in both direct liquid-to-chip cooling and immersion cooling solutions to maximize heat exchange within a limited footprint. This unit completely isolates
the facility water system (FWS) and technology cooling system (TCS) sides of the liquid cooling system and accurately controls the supply temperature and flow rate of the coolant while consuming minimal power.

Product Overview

At a glance Benefits Features Technical Data

Most important benefits

  • Supports Free Cooling throughout the year (ASHRAE W32 - W+ warm water cooling)
  • To enhance system compatibility, the unit offers a range of structural, electrical, and control options, including the flexibility to accommodate different liquids, power loads, and optional THDi filter

Most important features

  • Slightly oversized pipe diameter to increase watervolume and reduce pump power consumption
  • Variable-speed pumps ensure enhanced energy efficiency, especially under low loads, eliminating the need for liquid bypass
  • Optimized heat exchanger for the low temperature difference between the facility water system (FWS) and technology cooling system (TCS) circuits
