The entire refrigeration circuit including the air cooled condensing section is contained within the unit, and all plumbing and wiring was done at the factory. The interior of the unit is also Heresite-coated to withstand the caustic pool environment. With a flat plate heat exchanger operating at up to 82.5% effectiveness, this one unit provides worry-free, year-round air conditioning while also minimizing operating cost.
