Model LG Series - Compressors for Synthetic Refrigerants Lg Series Low-Gwp

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 the decreasing viscosity of the oil.
