Heat pump Water to Water Screw WSHP

Mammoth MWH series of water to water WSHP Screw Units has met highest demands with the reliability, safety, and flexibility. With advantages of high efficiency, low noise, simple and convenient operation, and convenient installation and maintenance, they are widely used in the factories, stations, hotels, restaurants, villas, office building, high-grade residence, etc.

The source of Water to water type water source/geothermal screw heat pump is geothermal and underground water, assisted with the electricity power. The unit uses the high quality semi-hermetic double screw type compressor, which is characteristic of few revolution parts and vulnerable parts, high intensity, long life, easy to service; Each unit uses the highly efficient horizontal-type shell and tube condenser and evaporator, the heat exchanger has the special fin enhanced so the heat transfer efficiency is high. The control system with perfect protective measures can monitor the unit operating condition at any moment. Each water source heat pump unit is tested roundly at the test laboratory.

Mammoth offers a complete line of water to water WSHP Screw Units from 70 ton to 960 ton capacity (250 - 3500 kW).
