What are High Temperature Heat Pumps (HTHPs)?

High-temperature heat pumps (HTHPs) efficiently generate heat between 85°C and 150°C+ (up to 200°C) by upgrading industrial waste heat or using advanced refrigerants. They bridge the gap between traditional heat pumps and boilers, providing sustainable, high-grade heat for industrial processes (drying, steam) and high-temperature hydronic heating systems.

How does HTHPs work?

Heat pump technology is a technology that transfers heat energy from low-grade heat sources to high-grade heat sources, and is a key technology for future energy conservation and carbon reduction.
