AC-M18 CBRN air conditioner for tent cooling.

The AC-M18 CBRN air conditioner is a portable unit developed primarily to provide air conditioning in temporary or transportable buildings or tents.

The AC-M18 CBRN is a compact, light-weight aluminium unit built into a rigid steel frame. The air conditioner is designed to operate on COLPRO applications with the evaporator module placed inside the shelter and the condenser module placed outside. The two modules are interconnected by refrigerant hoses and power cables.

The AC-M18 CBRN also operates with both modules placed outside with ducted supply and return air. A dual filtration system for the internal air path is available for selective filtration.

The function of the AC-M18 CBRN is based on a cooling circuit and two powerful fans. The evaporator section contains the evaporator and a radial fan which draws warm internal air through the cold evaporator and blows out the cooled air through the side or the top of the unit. The condenser section contains two condenser coils and a large axial fan returning the heat from the internal air to the outside.

HEPA filter unit
As a supplement to the AC-M18 CBRN aircon, a HEPA filter unit is available for use in clean room solutions. The HEPA filter unit can be fitted with different kinds of filters, depending on the actual requirements. Various filter types are available.

The HEPA filter unit is for external installation and it is mounted on top of the AC-M18 CBRN evaporator side, over the upper supply opening. The HEPA filter unit is designed for clean room solutions, such as field hospitals and workshops for sensitive equipment.

Up to four filters can be used in the air stream when mounting a HEPA filter unit on top of the AC-M18 CBRN (2 + 2 filters).

Wheel kit
A wheel kit is available as a basic add-on-solution which can be fitted to the AC-M18 CBRN on site without using any tools. Easily accessible handles lift the unit to transport mode and the AC-M18 CBRN can be transported and moved to the optimal position by one person. On sites where no forklift is available, the wheel solution enables rapid and easy deployment of the AC-M18 CBRN aircon.
