Gen3 Electrical Compressor. Sanden International (Europe) GmbH Am Taubenbaum 35-37 Bad Nauheim, Germany, 61231 + 49 6032 8030 0 Company # HRB 113309. Sabroe high-pressure screw compressor units The unique Sabroe high-pressure compressor units are ideal for large site-built ammonia heat pump installations that condense at either 90°C or 72°C. They are also the ideal choice for larger CO 2 systems or low-temperature two-stage freezer installations, such as carbon dioxide-ammonia (R744-R717) cascade refrigeration systems. With several patents and the development of the first automotive R744 compressor in mass market, OBRIST can offer profound knowledge whether it’s mobile or stationary.

Sanden International (Europe) GmbH Am Taubenbaum 35-37 Bad Nauheim, Germany, 61231 BOCK is one of the world‘s technology and innovation leaders in the development of environmentally friendly, economical solutions in the field of refrigeration and air-conditioning technology, including heat pumps and heat recovery – with one of the world‘s largest portfolios of compressors for natural refrigerants such as CO2 (R744), hydrocarbons and other low-GWP refrigerants.

This example models a vapor-compression refrigeration cycle in which the high pressure portion of the cycle operates in the supercritical fluid region. The refrigerant is carbon dioxide (CO2), also called R744 in this application. The compressor drives the flow of CO2 through the cycle and raises the pressure above the critical pressure.

The properties of R744 affect how the refrigerant is applied (see post 3 of this series for more details): The high density of R744 compared to hydrofluorocarbons (HFCs) results in the requirement for less compressor displacement, typically 1/5th of that needed for R404A. R744 compressor racks The racks we design and manufacture include the types: CASCADE (subcritical cycle): with primary condensation circuit in R134a / R449A / R407F or through circuit with water / glycol mixture produced by a chiller TRANSCRITICAL: the configurations of the transcritical units start from the basic BOOSTER system with various implementations that can include parallel Combination of low side R744 / CO₂ and R134a high side systems into the one compact unit.
