MOBILE CO2 COMPRESSOR
WITH INNOVATIVE "STAR" DRIVE DESIGN HR40 and HR60
The cylinders of the radial piston compressor are arranged in a star configuration around the crankshaft, resulting in an extremely compact compressor design that is perfectly matched to the natural refrigerant CO2 (R744) and mobile use.
The result for the user: Energy saving and LONGER RANGE
- No need for energy-consuming auxiliary heaters
- Up to 20% higher efficiency of the CO2 heat pump
- Approx. 40 % more vehicle range

SUSTAINABILITY IS IMPORTANT TO US:
BOCK USES R744 /CO2 AS REFRIGERANT!
CO2 is a natural refrigerant, environmentally friendly, inexpensive, compared with fluorinated refrigerants. It is colourless, non-flammable and non-toxic. CO2 is the basis for determining the CO2 equivalent of refrigerants.
R744 has a GWP value of 1 and is excluded from the so-called "Phase-Down-Zenario" (F-Gas-Regulation). From a weight of 5 tonnes CO2 equivalent, the leak test of a refrigeration system is mandatory. Therefore, the leak test is not required for refrigeration systems with R744 below a charge of 5 tonnes. If CO2 is released into the environment during service work, there is no need for costly refrigerant recovery.
Demanding factors are the high operating pressure of the refrigerant, the low critical point, dry ice formation when the temperature falls below the triple point and the very high standstill pressures. The requirements and component selection of the refrigeration system must be considered accordingly.
It's good to have an expert on hand here, or even a whole tool. Feel free to ask our experienced cooling experts in the field of CO2 or find out more about our BOCKCO2Tool and get an activation at: vap@bock.de
