3000 watts (planned) 5000 watts (planned)

• 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)
