Stirling engine with alphagamma® technology:
pure energy paired with environmental benefits

Our Stirling engine with the new alphagamma® technology represents a future technology that stands for an essential component of our climate goals.

When used as an auxiliary power unit, our technology maintains the on-board power supply in parked vehicles and avoids environmental pollution from engines running on the stand.

Another goal of our research and development is the low-maintenance use and disposal of greenhouse gases in lean gas CHPs.

alphagamma® technology by frauscher

Our alphagamma® technology is the result of 20 years of development and basic research on alpha, beta and gamma stirling engines. Our solution combines alpha and gamma stirling engines.

The advantages are revolutionary: severely reduced piston and bearing forces ensure an extremely long maintenance-free life.
