Differences between regular AHU and Hygienic AHU

Commonly called an AHU, an air handling unit has now become essential in many residential and commercial areas like data centers, hospitals, laboratories, offices etc to cool the indoor environments. It consists of a large metal box containing a blower, heating or cooling elements, dampers, sound absorbers and filter racks. Trosten specializes in manufacturing hygiene units with different configurations built to promote higher levels of hygiene in hospital environments all across the GCC region.

 So, what are the differences between regular AHU and Hygienic AHU?

 An air handling unit (AHU) filters and controls air quality in the indoor space with its air purification filter. These filters are intended for spaces where natural ventilation is limited and there is a crowd of people walking in and out of the premises. These AHU’s collect air from outside, which is treated and distributed throughout the rooms after being recycled.

 It regulates the air conditioning and conditions the temperature so that the environment is set to a comfortable temperature.

It monitors the humidity levels and with heat recovery units AHUs can reduce the consumption of energy needed in an air conditioner. The indoor and outdoor air is mixed so that when the air comes in contact with the coil the temperature contrast is lower making the climate contribution also lower. Some components of an AHU are

 ●      Filter: It purifies the air and can be adjusted according to the air purity requirements to filter out bacteria, air pollutants and viruses.

●      Fan: This electromechanical system powers the air to expel unhygienic air from the AHU to the ducts.

●      Heat exchangers: These devices transfer temperature between two fluids - the coolant and the air which is then separated by a solid barrier. 

Hygienic Air Handling Units or Hygienic AHUs are used in industries that need to give importance to maintaining a sensitive sterile environment and maximise hygienic conditions. They are used in pharmaceutical and medical industries, operating theaters and food industries.

It provides greater efficiency than a regular AHU in terms of filtration and is installed to better manage the indoor environment while reducing energy consumption and avoiding the spread of bacteria. Its hygienic sound absorbers are placed in the AHU to reduce the dust particles in the ductwork.

Hygienic Air Handling Units are coated with stainless steel and are covered with special joining pieces and sheets to prevent water accumulations and present a straight and smooth surface.

Trosten offers high quality air handling units that elevate the performance of centralized heating, ventilation and air conditioning equipment for various industries.
