ElectraTherms Green Machine

produces fuel-free, emission-free

power from low to mid tem-

perature waste heat using the

Organic Rankine Cycle (ORC) and

proprietary technology. The com-

panys proven, patented twinscrew expander enables its Heat

to Power generating system to

make electricity from waste heat

instead of fossil fuel. Small and

robust, this clean technology can

operate with cold water or air

condensing to provide reliable

power output.

ElectraTherms twin screw

expander offers distinct ad-

vantages for small-scale ORCs.

These advantages include simpledesign, low speed operation, 3:1

turn down ratio, no gear box or

oil pump, attractive payback and

proven technology. ElectraTh-

erms Green Machine represents

a dramatic change from radial

or axial turbine technologies,

providing a more cost efficient,

robust machine to generate

emission-free electricity from

existing unused heat without

added fuel.

When youre talking about waste heat, every business, every

ndustry, is generating some sort of energy byproduct, some

ort of heat; its going up in smoke stacks and nobody is using it.

And the question is, can we capture that energy and use it in a

mart way? Thats what ElectraTherm is all about.
