AIR COOLED DIRECT EXPANSION UNITS (DXA)
The air cooled DX units extract heat from the room and transfer it to
theoutsideusing air cooled refrigerantheatexchangers (condensers).

WATER COOLED DIRECT EXPANSION UNITS (DXW)
In the DX water cooled units, the heat extracted from the room is
transferredto water via a stainlesssteel brazed plate exchanger within
the unit.
The cooling water may be fed from the mains supply or a well (open
circuit), or recycled in a closed loop cooled by external coolers.
Inthe latter case, an anti-freezemixture of water andethyleneglycol is
normallyused.
The water cooled units have the advantage that the refrigerant circuits
arechargedandsealedinthefactory.Thismakesinstallationextremely
simple,eliminatingtheneed for any site-installed refrigerant pipework.
