ElectraTherm Technology

ElectraTherm combines traditional components with patented, cutting-edge technology to create electricity from waste heat. ElectraTherm power systems use a closed-loop organic Rankine cycle (ORC) to create pressure by boiling EPA-approved chemical working fluids into gas. The gas expands in a one way system and turns a patented Twin Screw Expander, which drives a generator to ultimately put out electricity.

Historically, ORCs incorporating turbo-expanders have not been commercially viable in sizes less than 1MW. By replacing turbo-expanders with ElectraTherm's patented, robust, low-cost Twin Screw Expander, users benefit from short payback on systems that provide unattended operation and negligible maintenance.

ElectraTherm's technology:

  • Lowest heat requirement in the industry: 200º F
    • ElectraTherm Technology
  • Flexible and scalable from 25kW-1MW
  • One third the cost of turbine generators
  • Lowest operation and maintenance requirements in the industry
  • Non-combustion process
  • Zero toxic byproducts
  • Zero emissions
  • Zero fossil fuel requirements
  • Modular and mobile
  • Carbon neutral
Waste heat generator
No company currently produces equipment competitive to ElectraTherm's low temperature, small scale, fuel-free, emission-free power systems.

ElectraTherm's Twin Screw Expander

Our patented Twin Screw Expander provides the ideal solution in the arena of small-scale waste heat generation. The Twin Screw Expander:
  • Costs 10 percent of comparable turbo expanders.
  • Runs at roughly 1/10 the rotational speed of turbo expanders.
    • ElectraTherm Twin Screw Expander
  • Performs with less friction and greater lobe strength than any other twin screw rotor profile.
  • Operates free of expensive gear boxes and/or electronics needed for high speed turbine operation.
  • Enhances the cycle by admitting wet vapor to the closed loop system (impossible with turbines), enabling ElectraTherm's patented process lubrication system which eliminates the need for traditional oil pump, tank, lines and filter.
  • Is bullet proof, built to perform in caustic environments that severely damage high-speed turbines and turbo expanders.
