LG Compressors – Low GWP Refrigeration Compressor Technology
LG Compressors are designed for modern refrigeration applications requiring efficient, reliable performance with lower Global Warming Potential (GWP) refrigerants. The BOCK HG-LG series uses advanced suction gas-cooled compressor technology, combining proven engineering with features specifically developed for today’s HFO and HFC refrigerants.
The range is suitable for HFO refrigerants in safety class A2L as well as chlorine-free HFC refrigerants in safety class A1, providing flexibility across commercial and industrial refrigeration applications.
Designed for HFO and HFC Refrigerants
LG Compressors feature an optimised drive designed for demanding operation with HFO refrigerants, together with seal materials specifically suited to both HFO and HFC applications.
Key features include:
- Suitable for HFO (A2L) and chlorine-free HFC (A1) refrigerants
- Optimised drive for demanding HFO applications
- HFO and HFC-compatible seal materials
- Electronic motor protection for installation in an external switch cabinet
- Reliable oil pump lubrication
- Excellent running characteristics
- High levels of efficiency and reliability
- Service-friendly construction with replaceable drive motors
When operating at evaporation temperatures above +15°C, ester oil C85E must be used.
Efficiency-Optimised HG…e Technology
The efficiency-optimised HG…e models within the LG Compressors range incorporate technical improvements designed to enhance motor efficiency, gas flow and valve-system performance.
These developments help provide efficient compressor operation while maintaining the reliability, serviceability and high-quality engineering associated with BOCK refrigeration compressors.
