DATA CENTER COOLING

The Munters advantage

Munters has a long-established reputation as the experts in energy efficient climate technology, providing customers around the world with industry-leading solutions since 1955. We are always focused on evolution and innovation, and this is especially apparent with our unique cooling media and modules designed for use in modern data centers.

Munters cooling solutions for data centers stand out and are designed to make data center cooling safer and more efficient – saving energy, water and space.

The difference in data center cooling

Data centers are an essential in our increasingly digital world, and the technology that stores all of this valuable information needs to operate in a certain type of climate. To provide that, Munters can offer outstanding solutions for cooling.

WET OR DRY PACKAGED SOLUTIONS – 100 TO 600 KW CAPACITY

Wet: Polymer Tube Heat Exchanger with Indirect Evaporative Cooling (Oasis®)

BENEFITS

  • 70-80% approach to ambient wet bulb for maximum “economizer cooling”
  • Reduce or eliminate mechanical cooling – peak PUE typically 1.25 or lower
  • Positively contains water to the scavenger side of heat exchanger
  • Polymer tubes flex during operation, shedding scale that forms during the evaporative process
  • Polymer and stainless steel heat exchanger construction minimizes corrosion and helps manage scale formation
  • Typically operates dry below 50°F reducing annual water consumption and eliminating freeze issues

Dry: Aluminum Plate or Heat Pipe Heat Exchanger with Sensible only Heat Transfer

BENEFITS

  • Waterless technology
  • 50-70% approach to ambient dry bulb for maximum “economizer cooling”
  • No moving parts for maximum reliability and minimum maintenance
  • Minimum filtration required for scavenger air (large HX plate spacing allows small particles to pass through)
  • Economizer savings available when ambient temperature is less than data
    center hot air return

DRY SPLIT SOLUTION – 400 KW CAPACITY

Thermosyphon Heat Exchanger (SyCool™ Split)

VIEW DETAILS

Thermosyphon heat exchangers move heat from the data center to ambient through the evaporation of liquid refrigerant in the SyCool CRAH, and condensing of the same refrigerant in the SyCool condenser. The CRAH is connected to the condenser with up to 500 ft (equivalent straight pipe length) of low pressure thermosyphon refrigerant piping. Heat is exchanged passively for “free cooling” of the data center when ambient conditions are favorable. A simplified version of the system is schematically shown below right.

  • Split system eliminates duct penetrations through the building envelope
  • No water consumption
  • Typical operation with up to 70% approach to ambient temperature for best in class free cooling Transitions to full DX only as ambient temperature approaches the hot air temperature from the servers
  • Low peak power
  • Thermosyphon piping is low pressure allowing time saving mechanical pipe joining systems such as Victaulic to be used
  • CRAH units can be installed side-by-side allowing maximum airflow required by higher density installations
