Frequently Asked Questions

What is a computer room air handler or CRAH unit?

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.

How does a CRAH unit work?

CRAHs play a vital role in maintaining the environmental conditions necessary for the optimal performance and longevity of data center equipment. They help prevent overheating, ensure proper air circulation, and contribute to the overall energy efficiency and reliability of the data center.

CRAC vs CRAH: What’s the difference?

CRAC (Computer Room Air Conditioner) units use direct expansion cooling with refrigerant to remove heat from data centers, while CRAH (Computer Room Air Handler) units use chilled water from an external chiller. CRAC systems are typically more efficient for smaller setups, whereas CRAH systems are preferred for larger facilities due to their scalability and efficiency in handling higher cooling loads.
