Turning heat into electricity: the key

More than 28 % electrical energy from the supplied heat flow

Our innovative generator modules absorb heat from a heat source and convert it directly into electrical power: sustainable, quiet and maintenance-free for up to 10,000 hours.

Building on Stirling engine technology, we invented the alphagamma® process, which, after more than two decades of research and development, represents a new standard in the field of heat engines. These tireless, long-running engines, featuring lubricant-free technology, offer high efficiency and allow for unprecedented flexibility in adapting to different heat sources.

The fast track to a micro CHP unit

The development of low-emission firing systems is a top priority for many companies. The integration of a Stirling generator module would require the burner or boiler control system to be adapted or redeveloped for testing phase, which would entail considerable expense.

Frauscher Motors supports the construction of a micro CHP unit based on a firing system provided by the customer with ready-to-use control modules. The functions include manual or automatic start of the Stirling module when heat is supplied, rectification of the generator current, charge control of the buffer battery and display of the most important operating values including safety functions.

This allows valuable insights to be gained right from the start for stable operation in series applications.

Principle illustration of a Stirling micro CHP unit

The generator unit’s heat exchanger absorbs thermal energy and, once a set temperature is reached, the module starts up automatically. The highly efficient synchronous generator immediately supplies three-phase alternating current, which is rectified by the control module and fed either to a suitable inverter (grid-connected operation) or to a storage battery (back-up or off-grid operation).

The generator unit also produces cooling capacity, which should be dissipated into the heatingsystem or other heat sinks. Precautions have been taken to deal with power cuts or other disruptions.

Safety note:

The Gen70xx series and Gen 500 series product ranges are intended exclusively for companies and research and training departments that have the relevant experience and technical approvals in the handling of hot gases, combustion technology, exhaust gas regulations and electrical control technology. We therefore ask for your understanding that we cannot respond to enquiries outside this specialist group.
