Features of Stirling engine

80 watts, 800 watts (current product), Cryo S 77K (new product)

3000 watts (planned) 5000 watts (planned)

80 watts,800watts

• Fully sealed engine with low engine noise (60Db)

• Realizes cogeneration power generation at low temperatures of 180 ° C to 600 ° C as well as cryogenic temperatures.

• High energy consumption efficiency (COP) capacity.

• Can generate electricity with propane gas, city gas or biomass

• 800 Watts (water-cooled, Power Factor 95%) –

• Reach -120 ° C in 10-20 minutes. Maximum temperature is -100 ℃

• 80 Watts (air-cooled, Power Factor 90%) –

• Achieve -60 ° C in 10-20 minutes, up to -80 ° C

• 25,000 hours continuous operation (7 years – 24 hours, operational)

• No maintenance required

• Clean energy (using helium gas as working gas)

• (No chlorofluorocarbons required and no damage to the ozone layer)
