Compressor & Expander

A solution for every demand

Different applications need different solutions in terms of machine concepts and machine sizes. Regardless of if you want to compress or expand working fluids, OBRIST Engineering can offer the full service of technology selection and development of compressors and expanders.

OBRIST Engineering scroll technology

SCROLL

One of its main advantages is the superior noise level, which makes it especially suitable for hybrid and electric cars.

The Smooth Technology

For more than 15 years we have designed and developed various scroll compressors and expanders. The range goes from 4 to more than 200 cm³ per revolution, pressures from 80mbar to 140bar and various working fluids like Air, R744, Ethanol, and Propane. These days, hybrid and electric vehicles require highly efficient, low noise eScroll compressors from 48 to 800V.
