Learn what a computer room air handler (CRAH) is, how it works, and why a CRAH unit can be a smart component of data center HVAC systems.
Quick Facts
A Computer Room Air Handler (CRAH) is a cooling unit used to regulate the temperature and ensure optimal operating conditions for IT equipment. CRAH units are essential for cooling central IT infrastructure, ensuring stable and reliable operation of critical equipment. The CRAH unit is used in electrical rooms to cool power and network equipment in colocation and hyperscale data centers. The CRAH is also used in the white space and acts as supplemental cooling alongside chilled water systems.
Unlike computer room air conditioners (CRACs), a CRAH does not have its own internal compressor or refrigerant. Instead, it relies on a central chiller plant, such as a high-efficiency Trane air-cooled or water-cooled chiller, to supply chilled water.
There are several benefits to including CRAH units in your data center HVAC system:
For efficiency, scalability, and reliability, computer room air handlers are a critical component in data center cooling systems. To learn more about these units, contact your local Trane representative today!
