Air Handling Unit

An air handling unit (AHU) is a device used to regulate and circulate air as part of a HVAC system. It is widely suitable for medium or large commercial/industrial buildings, and can be installed conveniently on the roof, basement or floor of the building. AHUs uses a mixture of outside air and recirculated air from the building to filter, cool and heat. The energy recovery devices in the AHU transfer heat/moisture from exhausted air to supply air or vice versa, reducing energy usage while providing fresh air to the building.
