ACM 18

Function

The ACM 18 Air Conditioner is a transportable unit, developed primarily to provide air conditioning in temporary or transportable buildings or tents. It is a small light weight unit made out of aluminium and built into a rigid steel frame. The unit is designed to be placed outside, with supply air and return air ducted to the tent. For field hospitals where a higher filtration than for normal accommodation is wanted, a dual filtration system for the internal air path is available.

The function of the ACM 18 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 of the tent 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 taken from the internal air to the outside atmosphere.

The ACM 18 can be equipped with an electric heating coil, to provide heating for example for night time when temperatures can fall under 20°C.

All sheet metal parts are protected against corrosion by a minimum 80 μm top coat.

Features

• Designed for optimal utilisation of a standard 20” ISO container (24 pcs.)
• The ACM 18 is built into a strong metal frame with insulated panels where relevant, powder coated.
• Top finish painting is standard sand colour
• Designed for air conditioning when the temperature is above 20°C. It can provide cooling at ambient temperatures up to +60°C. Option with built in heating will heat when ambient temperature is below 20°C.
• Scroll compressor for a high degree of reliability and low noise level.
• Automatic phase surveillance
• Environment-friendly R134a refrigerant.
• HP/LP pressostat switches ensuring long compressor lifetime.
• Controlled by a room thermostat placed inside the tent (accessory)
• G3 filtration of the internal air
• Dual filters in front of internal air intake as an option
