Air Handling Unit
Air Handling Unit

Air Handling Unit

Air handling units (AHU) are the lungs of any HVAC system. An air handling unit is a device used to regulate and circulate air as part of the heating, ventilation and air conditioning system. The AHU takes in outside air, reconditions (filtered and either heated or cooled) it and supplies it as fresh air to the air conditioned room. 

AHU’s for the marine and offshore industry

As our air handling units are used in the marine and offshore industry, it is essential that they are made of high-quality materials to withstand the extreme sea climate conditions. The AHU is made of galvanized steel or stainless steel and has an aluminum frame with double-walled panels made of galvanized steel (stainless steel as option). Explosion proof fan motors are available on request.

The casing

The air-handling unit has an aluminum frame with double-walled panels made of galvanized steel (stainless steel as option). The panels are internally insulated with thermal and acoustical insulation. Rock wool type: 223 cross-sections 25 mm.

Fan

The air-handling unit has a direct-driven or belt-driven centrifugal fan, depending on the required air quantity and air pressure. The air-handling unit can be provided with a plug fan to save space.

Air handling unit functions

Installed on a common base frame, the single duct air handling unit has the following functions:​

  • Filtering function with EU-class filter
  • Heating function with electrical heater or hot-water heating coil
