CO2 transcritical and subcritical
Wide range of applications
CO2 specialists for small and large performance requirements
With their wide application limits and frequency ranges the gas cooled BOCK CO2 compressors offer suitable solutions for stationary and mobile applications.
All transcritical and subcritical CO2 compressors flexibly adapt their heating and cooling capacity to the requirements. Its wide range of applications enables
tailor-made, cost-saving solutions for the most diverse applications – and all this with the highest reliability and durability.
Bock CO2 compressors support the fulfilment of important energy and environmental protection requirements, such as the European F-Gas Regulation or the worldwide Kigali Agreement, and meet strict requirements of European standards and ASERCOM guidelines.
Even for small capacities, Bock relies on the proven oil pump for a reliable oil supply in the compressor - even under demanding conditions. The basis for this is a CO2-optimized driving gear design combined with proven BOCK compressor technology.

Transcritical: 4 sizes
19 displacement stages
LP/HP: 100 /150 bar
With their optimised efficiency, the gas-cooled semi-hermetic CO2 compressors achieve the highest EER/COP values within their range of applications - officially confirmed by ASERCOM (Association of European Refrigeration Component Manufacturers) certification for several displacement stages.
Further advantages of reciprocating compressors: highest reliability and durability.
Subcritical: 4 sizes
17 displacement stages
LP/HP: 40 (30) / 55 bar
LT series: 1 model
6 displacements
LP/HP: 100 /100 bar
The subcritical series is based on the advantages of the proven BOCK HG compressor technology, which has been holistically optimised to meet the requirements of CO2 operating conditions in low temperature applications.
For special specifications with high standstill pressures, the LT series was developed - available in the two motor versions ML and S for a wide frequency band and greater operating limits.
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 BOCKCO2 Tool and get an activation at: vap@bock.de
