Semi-hermetic compressors for air-conditioning applications
with R407C

Based on our currents semi-hermetic product range, with its outstanding advantages and features, there is now a compressor series available for the use with the refrigerant R407C with expanded fields of application.

Those compressors are especially suited for the application in mobile air-conditioning systems, such as railway air-conditioning.

Condensing pressures of up to 35 bar possible (approx. 74°C condensing temperature).

Special features

To ensure the reliable operation of the refrigerant R407C in countries with high ambient temperatures of up to 50°C, Bock compressors for R407C are approved for a maximum operating pressure of 35 bar. This corresponds to a condensing temperature of approx. 74°C and opens up completely new possibilities for the use of this refrigerant. To guarantee the highest possible operational safety, Bock uses its long experience with special compressors for other high pressure refrigerants that are already used thousands of times in many mobile and stationary applications.

The refrigerant R407C

Besides R407C, R410A is also considered a long-term replacement refrigerant for R22. In addition, it is an alternative to R134a. It is almost azeotropic and behaves like a single component refrigerant – the temperature glide is very small. Suitable refrigeration oils are ester oils, such as e.g. Fuchs Reniso SE55.
