Screw Chillers (Heat Pumps)
Screw Chillers (Heat Pumps)

The Thunderbolt series of high efficiency inverter water screw heat pump units are the main products of Mammoth. The Thunderbolt series is equipped with the newly CMC800 Chinese touch screen intelligent control system. The units are available in a wide range of models and configurations to meet the needs of different customers. This series of units are energy efficient, stable and reliable, with a wide range of applications and simple maintenance. The Thunderbolt series can be used in comfort air conditioning, heat pumps, air conditioning + heat recovery and other applications where the heat recovery temperature can reach up to 65°C. This makes the Thunderbolt series widely used in a variety of energy-saving air conditioning and refrigeration systems.

Environmentally friendly and energy efficient
●  The whole series can meet the energy efficiency requirements of energy saving products;
● Semi-hermetic screw compressors optimized for HFC-134a refrigerant for efficient and reliable operation under different operating conditions;
● Flooded type evaporator for higher heat transfer efficiency;
● Less refrigerant charge for better environmental care;
● Adopting system flow automatic matching control and exhaust super-heat control ensure system efficiency;
● Electronic expansion valve throttling control ensures variable operating efficiency.
