AHU Manufacturer

Trosten industries, a part of Bin Dasmal Group, being one of top air handling unit suppliers in the UAE has expanded its market reach to provide engineering solutions in the GCC Region, including Oman, KSA, Bahrain, Kuwait.  

Single skin and double skin air handling units regulate the temperature within the operating space with minimum utilization of electricity which in turn saves power.

Let us take a closer look at the differences between the single skin and double skin air handling unit and which one you could choose for your desired space. 

  • Single skin AHU

This device is composed of aluminum or stainless steel and operates without making a commotion. It features a robust, lightweight, and long-lasting HVAC supplement that is responsible for an efficient operation. It has standard panels that are typically 20/25 mm thick. 

The main advantage of single AHU’s is its simplicity in design and maintenance and reasonable cost. The purpose of this device is to collect outdoor air and consolidate it with the indoor air followed by cooling or heating it and letting it into the building premises. 

Single AHUs consist of an air handling unit that combines a heat source, cooling source and distribution ductwork. It can be wholly integrated where heating and cooling sources are detached. The integrated package is commonly installed in the ceiling and supplies the conditioned air into spaces with the same thermal zone.

  • Double AHU

Unlike single skin air handlers, this device is integrated and differs in structure. It is composed of a self-supported profile of extruded aluminum. It comprises insulated panels that are 25-45 mm thick and includes belt-driven curve blowers and dual sloping drain pan. They are equipped with air mixing chambers and can be manually or automatically controlled.

The main distinction between a single skin and double skin AHU is that the double skin is supplied with a cooling coil and connected with a compressing unit. This cooling coil is placed before the blower to cool the air that passes through the air handling unit. Trosten industries, a part of Bin Dasmal Group, has established itself as a certified HVAC equipment supplier in the UAE and provides premium quality AHUs for hospitals, laboratories, clean rooms and more.
