Green Machine 4400 - Up to 65kWe
DESCRIPTION
ElectraTherm’s Green Machine produces fuel-free, emission-free power from low
grade waste heat using the Organic Rankine Cycle (ORC) and proprietary technology. The company’s proven, patented twin screw expander enables its heatto-power generating system to make electricity from waste heat instead of fossil
fuel. ElectraTherm’s Green Machine represents a dramatic change from radial
or axial turbine technologies, providing a more cost efficient, robust machine to
generate fuel-free and emission- free electricity from a variety of heat sources.
ElectraTherm’s twin screw expander offers distinct advantages for small-scale
ORCs. These advantages include a simple and compact design, low speed operation with the ability to handle heat input variations and dual phase flow of the
working fluid, significant part load capability, no gear box or oil pump, attractive
payback and proven technology.
