Heliex’s screw expander systems have applications in any process that produces waste heat, including wet steam, from 150 up to 300 deg C and higher in certain circumstances. Important applications for it exist in electricity generation, petrochemical industries, glass and refractories, pharmaceuticals, food, brewing and distilling, paper production, biomass and land fill gas engines.

This is not an exhaustive list and industrial diesel engines and gas turbines, combined heat and power systems, geothermal power stations and processes utilising steam pressure reduction valves can all improve their energy economics through Heliex’s screw expander sets comprising expanders with outputs from 70 to 500kWe. The sets can be supplied in multiple installations for higher powers and as 2 stage installations for high pressure drops.
