Posted on Posted in Facilities Management

Consistent, well-planned  preventive maintenance of your air handling system, including your Air Handling Unit (AHU), ductwork and ventilation fans. is one of the most effective ways of saving energy and prolonging the life of your equipment.

What is an Air Handling Unit (AHU)?

An air handling unit, often called an AHU, is the composition of elements that is mounted in large, accessible box-shaped units called modules. It houses the appropriate ventilation requirements for purifying, air-conditioning or renewing the indoor air in a building or premises. Usually, it is installed on the roof of buildings.

The function of an AHU is to filter and treat air as well as to circulate it to where it needs to be. Typically, it is made up of a fan, heating and cooling coils, humidification equipment, filters and dampers. The treated air is circulated through the building space and returned to the unit by ductwork.

Additionally, it performs other functions including filtrating and controlling air quality, controlling air temperature, and monitoring relative humidity for indoor comfort.

AHU units are intended for places wherein the flow of people is large and natural ventilation is limited or for spaces that have high hygiene requirements.
