Air Handling Unit (AHU) An Air Handling Unit (AHU) is used to re-condition and circulate air as part of a heating, ventilating and air-conditioning system.An Air Handling Unit (AHU) is used to re-condition and circulate air as part of a heating, ventilating and air-conditioning system.The basic function of the AHU is take in outside air, re-condition it and supply it as fresh air to a building. All exhaust air is removed, which creates an acceptable indoor air quality. Depending on the required temperature of the re-conditioned air, the fresh air is either heated by a recovery unit or heating coil, or cooled by a cooling coil.In buildings, where the hygienic requirements for air quality are lower, some of the air from the rooms can be re-circulated via a mixing chamber and this can result in significant energy savings. A mixing chamber has dampers for controlling the ratio between the return, outside and exhaust air. The AHU is a large metal box containing separate ventilators for supply and exhaust, heating coil, cooling coil, heating/cooling recovery system, air filter racks or chambers, sound attenuators, mixing chamber, and dampers.

AHUs connect to ductwork that distributes the conditioned air through the building, and returns it to the AHU.A heat/cooling recovery exchanger is normally fitted to the AHU for energy savings and increasing capacity.An AHU designed for outdoor use, typically on roofs, is also known as a rooftop unit (RTU).

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. 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 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.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.Installed on a common base frame, the single duct air handling unit has the following functions:​Installed on a common base frame, the dual duct air handling unit has the following functions:Alternatives are available on request.Find AHRI Certified® Central Station Air-Handling Unit Supply Fans. Related Standards:  430 (I-P)  and  431 (SI) Product-Specific Operations Manual 2016 AHU-DS1 (AHU Data Form) Complete this form for each AHU specification sheet verification request and send to Mary Opalka. A copy of the output sheet from the manufacturer’s Selection Rating Software must be submitted in conjunction with this form. All fields must be completed prior to submission. Only the supply fan performance (bhp and RPM) is verified. Please allow ten (10) calendar days for AHRI to conduct verification and respond to your request. The certification program includes: A Central Station Air-Handling Unit is factory-made encased assembly consisting of a fan or fans and other necessary equipment to perform one or more of the functions of circulating, cleaning, heating, cooling, humidifying, dehumidifying and mixing of air.

It shall not contain a source of cooling or heating other than gas or electric heat. The AHU shall have a maximum design external static pressure (ESP) greater than 1.0 in H2O [0.25 kPa]. While the ESP for a specific application may be less than 1.0 in H2O, any units generally capable of delivering greater than 1.0 in H2O ESP shall be considered to be an AHU. This certification program applies to supply fan ratings for plenum fans in a cabinet with a full face opening axial discharge, fan arrays in a cabinet, housed centrifugal fans, and axial fans. The rules and procedures for obtaining and maintaining certification are detailed in the Resources section above. The specific Standard listed above details the technical requirements for rating and publishing your product performance, the AHRI General Operations Manual (OM) details the program operational rules that are generic to all of AHRI’s certification programs and lastly, the Product-specific Operations Manual provides the operational rules that are specific to this program along with the required documents and fees.
