Refrigeration Expert Info
Compared to standard HFC refrigerants, e.g. R404A and R134a, HFO refrigerants such as R455A or R1234ze place significantly higher demands on the compressors - in particular in terms of the engine, keyword emergency running properties.
The reason: HFO refrigerants have a significantly higher solubility in the oil, which leads to a strong reduction of the oil viscosity and thus increases the susceptibility to compressor damage. Therefore, the experienced Bock engineers used their experience in dealing with technically demanding refrigerants such as CO2 and hydrocarbons.
The result: the development of a special engine design for the new LG series. The compressors of this compressor type are "more insensitive" to decreasing viscosity of the oil.
LG compressor - More BENEFITS
- HFO refrigerants require special compressor technology: Long-term tests in various refrigeration applications internally and externally.
- Expert knowledge and decades of experience for:
- Robustness, Reliability
- Durability over the entire life cycle of a system
- More functional reliability
- LG compressors are a separate series based on the semi-hermetic, suction gas-cooled HG compressor range
- Optimized Driving Gear: more resistant compressors to decreasing oil viscosity
- Solution for low-GWP HFO refrigerants: only one compressor version for all common refrigerants
LG compressors from Bock offer individually plannable, economical refrigeration system construction and let and are configurated for future-proof refrigerants that safely and sustainably fulfil the requirements for the global phase down of F-gases (F-gas regulation, Kigali Amendment etc.).
HIGHLIGHT 2021: BOCK AIR-COOLED HA COMPRESSORS
NOW ALSO IN THE LG VERSION!
RELIABLE DEEP COOLING FROM THE COMPRESSOR SPECIALIST: HA-LG COMPRESSORS!
This means that our semi-hermetic air-cooled compressor is now available as a low-GWP version. The HA-LG compressor is direct-intake and the motor is air-cooled.
The combination of two ingenious BOCK development principles come together and provide an immense increase in performance and range of application.
