Our company’s products meet the most strict quality standards, occupational safety and environmental protection.
Heliex Power Ltd.
Heliex intends to be the World’s leader in steam screw expanders and their applications in the recovery of energy from industrial processes. The core technology is a novel rotary screw expander which recovers low-grade energy from steam and uses it to generate electricity. In some applications power can be generated where previously there was no economically viable opportunity to do so due to the temperature and wet steam conditions, for example from combustion engines and industrial furnace exhaust gas. The technology is also relevant to electricity generation in steam pressure let down systems, energy recovery indirectly in geothermal applications with high pressure and temperature water and intermediate/bottoming energy recovery from steam cycles.
Heliex expander systems are self-contained skid mounted generator sets incorporating G59 protection and designed to sit on normal factory floors or roadways without special foundations.
