Features

Product Overview

Double-skin air handling unit adopts double-layer insulated panels to avoid cold bridge, reduce air leakage and heat loss. With modular design, it can be configured with filtration, cooling, heating and humidification sections. Featuring low noise, stable operation and easy maintenance, this AHU is widely used for cleanrooms, factories and commercial buildings to provide precise air treatment.

 

Construction and Design 

  • Outer Skin: Made of galvanized or pre-coated steel to resist outdoor and environmentaldamage.
  • Inner Skin: Made of galvanized or stainless steel for hygiene and smooth airflow.
  • Insulation Core: Filled with Polyurethane Foam (PUF) or rock wool (typically 25 mm to 50 mm thick) to stop heat loss.
  • Frame: Built using strong, extruded aluminum or stainless steel profiles.

Difference

Single layer skin AHU

The chassis of the device is a single piece made of aluminum, stainless steel, or GI material. It runs quietly, with airflow capacity limited between 500cfm and 30000cfm. This is an efficient device equipped with CHW/HW/DZ heat conduction coils, suitable for people looking for single-layer AHUs in Dubai. It is equipped with EU2 and 13 type filters, therefore it has special corrosion resistance.

 

Double skin AHU

The device is interconnected, in contrast to a single-layer AHU. Its design and layout are different. It adopts self-supporting aluminum extruded profiles. It is equipped with insulation boards ranging in thickness from 25mm to 45mm. It is also equipped with a double inclined drainage pan and a belt driven meandering blower.
They also have CHW, HW, and DZ coils, which work very well. They usually include insulation and flatness in the frame

Assembler section. They are equipped with air mixing chambers that can be operated manually or automatically.

 

The main difference between single-layer and double-layer AHUs

 

(1) Less noise

Due to the thicker shell plate used in the double-layer AHU, it is quieter and quieter than the single-layer AHU.

 

(2) Higher structural strength

Due to the reinforced frame structure of the double-layer AHU, it delivers better structural rigidity than the single-layer AHU.

 

(3) Save floor space

Due to the stacked upper and lower structure adopted by the double-layer AHU, it occupies less floor space than the single-layer AHU. With its compact stacked layout, the double-layer AHU is more suitable for projects with limited room floor area. Thanks to its reduced footprint, it helps cut civil construction space cost compared with the single-layer AHU.
