• Low emissions
• Noiseless and vibration-free operation
• Special foundation is not required

The systems are based on external combustion engines put into operation by an external heat source due to temperature difference created by external heating and cooling sources. Heat can be supplied by an external heat source or generated by burning a wide range of fuels inside the combustion chamber.

The process results in rotation of the generator mounted on the engine, whereby energy is generated. There are no valves in the external combustion engine. It is hermetically sealed, and air is heated and cooled by means of hot and cold loop heat-exchangers. The process also generates heat which is used for combined power and heat production.

One packaged module-type system (2,5×0,9×2,0 m, 1800 kg) provides electric power to 38 kW and produces 65 kW-h of recovered heat, and has combined heat and power production system supplied in a special order. Total efficiency achieves 75%.

During combustion almost 100% of hydrocarbons are burnt with very low emissions. The systems are fully-automated and provide reliability and a long service life. They are low-maintenance, mounted on unprepared sites, run quietly and without vibration.
