Air Cooled Mini Chiller & Heat Pump

MAMMOTH MAC Air-Cooled Chillers & heat pumps are a product of the Mammoth commitment to offer quiet, reliable, energy efficient equipment-an approach incorporating high quality compressors, state-of-the-art coil design, and innovative packaging. MAC chillers are factory assembled and mounted on a heavy-gauge steel channel base. The base rails, supports and cabinetry are powder-coat painted. The base distributes the unit weight for roof loading. Varied and convenient installation is possible by virtue of the unit's small footprint. Using Sanyo's Scroll compressors tandems and triples provides four to six steps of capacity modulation depending on model size. Two compressors can run, depending on the load of the system, resulting in excellent part-load efficiency. Each refrigerant circuit has specially designed oil and gas equalization lines to control oil migration. These rugged hermetic compressors are constructed with an integral cast iron frame, cast iron scrolls, three Teflon impregnated bearings, and three oil filtration devices for each compressor. Condenser coils have internally enhanced seamless copper tubes arranged in a staggered row pattern.

The coils are mechanically expanded into McQuay lanced and rippled aluminum fins with full fin collars. A variety of optional coil material and coatings are available for corrosive atmospheres. An integral subcooler circuit provides subcooling to greatly reduce the possibility of liquid flashing. The external condenser coils are fitted with a protective wire mesh guard. Multiple direct drive dynamically balanced propeller fans operate in formed venture openings at low tip speeds for maximum efficiency and minimum noise and vibration. A heavy-gauge vinyl - coated fan guard protects each fan. Each condenser fan motor (including the optional OFSC fan motor) is Totally Enclosed Air Over, heavy-duty, 3-phase with permanently lubricated ball bearings and inherent overload protection. The evaporator is a compact, high efficiency, dual circuit, brazed plate-to-plate type heat exchanger consisting of parallel stainless steel plates.
