CRAH is a vital part of any data center cooling system. Let’s go over what’s new in Trane’s computer room air handlers so you’ll be ready to upgrade your Seattle or Tacoma facility. We’ll also answer your questions about CRAH units before we go into the specs.
What is a CRAH unit?
A Computer Room Air Handler is a cooling unit to ensure your IT equipment stays at its optimal temperature for proper operation. This is necessary because computers generate a lot of heat and while they have built-in fans for cooling, they also need the entire room to be cool enough.
That’s where a CRAH unit comes in. It provides ample cooling power to keep the entire room at the right temperature and can be used for supplemental cooling along chilled water systems.
How does a CRAH unit work?
It helps maintain ideal environmental conditions for the best performance of your data center equipment, which also makes it last longer. Specifically, it prevents overheating, manages humidity, circulates air, and contributes to the overall energy efficiency of the data center.
What’s the difference between CRAC and CRAH?
Computer Room Air Conditioning (CRAC) uses refrigerants to cool the air. This is usually what is used in smaller setups or rooms and uses a lot of energy. CRAH is more energy efficient because it uses chilled water to cool the air. It’s more suitable for large-scale and/or high-performance data centers.
CRAC is common in older and smaller systems while CRAH is better if you need a solution for a large area that is more energy efficient.

Superior performance & temp control
Regulates temperature by removing the heat produced by servers and other equipment. This prevents overheating which often leads to equipment failure and data loss.
Energy efficiency & sustainability
Computer room air handler units are energy efficient, so they reduce the overall power consumption of a data center, which is vital for cost management and sustainability.
Scalability & flexibility
Built for growing data centers, CRAH units can easily be added to existing systems to manage an increased cooling load without problems.
Redundancy & reliability
CRAHs are often part of a redundant cooling system meaning that if one unit fails, others take on the load. This design is vital for maintaining uptime and reliability.
