ElectraTherm Waste Heat Generator

The ElectraTherm Waste Heat Generator (WHG) captures waste heat from almost any geothermal or industrial source to generate fuel-free, emission-free electricity. Built on a skid, it's both modular and mobile, meaning it's easy to transport and install as a single unit or in a series. Automated control systems permit unattended operation resulting in low operation and maintenance costs.

The ElectraTherm Green Machine, installed at Southern Methodist University in 2008, is the world's first commercially viable WHG, using patented heat and pressure recovery technology that requires minimal heat (200 degrees F liquid) and is low cost, fuel-free and emissions-free. The system has exceeded expectations, reaching output well beyond its 50kW rating.

ElectraTherm Gas Pressure Reduction Generator

The ElectraTherm Gas Pressure Reduction Generator (GPRG) was developed for the oil and gas industry, to utilize the energy contained in the pressure drop of any gas to produce non-combustable, fuel-free, emission-free electricity. Built on a skid, it's both modular and mobile, meaning it's easy to transport and install. Automated control systems permit unattended operation resulting in low operation and maintenance costs.

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: 200° F
• 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

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.
• 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.
