Standard model of the high pressure (50bar) compressor series Compatible with natural refrigerants
Reciprocating Compressor [Single Stage] Open Type
HK-SERIES
A compressor compatible with ammonia heat pump systems
50bar high pressure design
High reliability
Achieved condensing temperature at 85 ℃ to operate with ammonia heat pump systems. This series can also be used for systems utilizing exhaust and waste heat.
From CO₂ cascades to ammonia heat pumps, these compressors are designed for a wide temperature range. This series can also be used for CO₂ hot gas defrost systems.
Since its production launch in 2004, the HK series has become the trusted model for many applications.
