refrigerants
We are green
By company philosophy, OBRIST Engineering is focused on green, environmentally friendly solutions. Historically linked and well experienced, we developed many system and component solutions with R744 (carbon dioxide) as one alternative to chemical fluids. Beyond that, any other applications have strong focus on natural, green working fluids such as R290 (propane), ethanol and more.
The benefits of R744
R744 is climate neutral and its Global Warming Potential (GWP) is 1300 times lower than the common fluorocarbon refrigerant, R134a.
We have converted and built-up more than 50 development vehicles to R744.

- Supporting the R744 A/C System and Compressor from Daimler
- First series automotive R744 compressor worldwide
- Swivel joint technology (invented by us)
- Natural refrigerant with GWP:1
The benefits of R290
R290 has a low Global Warming Potential (GWP) of 3 making it one of the most climate-friendly and cost effective refrigerants on the market. It’s capacity to absorb heat is nearly 90% higher than R134 or R404 which results in quicker temperature recovery and lower energy consumption.
