The VA-M15MKII Warm Air Heater is a transportable unit, developed primarily to provide heating in tents or temporary, transportable buildings. The unit is designed to be placed outside the tent, with supply and return air ducted to the tent.
The VA-M15MKII heater operates on the in-direct fired (clean
air) principle thus insuring that no combustion products or fumes are
introduced into the occupied spaces. The forced air system provides for the
most rapid warm-up capability.
The VA-M15MKII heater is essentially self-contained, requiring only a source of external electric power and fuel. The unit will operate effectively on almost all diesel fuels. Appropriate fuels are supplied by the fuel hose assembly which may be connected to external jerry cans or drums.
The AC-M18 air conditioner is a portable unit developed primarily to provide air conditioning in temporary or transportable buildings or tents. It is a compact, light-weight aluminium unit built into a rigid steel frame.
The AC-M18 is designed for outside installation with ducted supply and return air. For field hospitals, where the need for filtration is higher than that of normal accommodation, a dual filtration system for the internal air path is available. The AC-M18 is also available as a split system for sealed applications (AC-M18 CBRN).
The function of the AC-M18 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.
The AC-M18 can be equipped with an electric heating coil to
provide heating for example for night time when temperatures can fall under
