What is an air handling unit (AHU)?

An AHU is a system that conditions and circulates air to control temperature, humidity, and airflow within a facility.

How are AHUs used in data centers?

AHUs manage large air volumes to ensure stable consistent air conditions and support efficient cooling concepts.

What is the difference between an AHU and a CRAH unit?

A CRAH (Computer Room Air Handler) is a chilled-water cooling unit designed specifically for data center applications. An AHU (Air Handling Unit) is a customized air handling solution that can be configured for different cooling technologies and application requirements, including chilled water (CW) or direct expansion (DX) systems.

What is Free Cooling in air handling units?

Free Cooling uses outside air to reduce mechanical cooling operation and energy consumption.

Can AHUs be customized for specific projects?

Yes, STULZ offers custom air handling units tailored to individual project and site requirements.
