ElectraTherm Commissions 10 Green Machines on District Heating System in Europe

Waste Heat to Power Improves Gas Turbines Efficiency to Generate an Additional Half Megawatt

RENO, NV--(Marketwired - Aug 7, 2014) - ElectraTherm, a leader in distributed heat to power generation, commissioned 10 Green Machine 4400s in Levice, Slovakia in June 2014. ElectraTherm's Czech distributor, GB Consulting, facilitated the deployment of Organic Rankine Cycle (ORC) systems on a centralized district heating system in Slovakia as a means of increasing on-site efficiency and generating clean energy. To date, the site has accumulated over 12,000 hours and ElectraTherm's entire installed base has surpassed 230,000 hours (26 years) of runtime with 41 machines in the field.

ElectraTherm's Green Machine generates fuel-free, emission-free power from low temperature waste heat. The 10-machine installation utilizes the waste heat from two Rolls Royce gas turbines through a combined cycle. Exhaust from the turbines goes through a heat recovery steam generator, and lower temperature exhaust gas that cannot be utilized produces hot water to meet demand for heating on the municipality's district heating system. The remaining heat runs through ElectraTherm's Green Machines to generate clean energy and attain attractive feed-in-tariff incentives.

Hot water enters the Green Machine at between 77-116°C (170-240°F), where it heats a working fluid into pressurized vapor, using Organic Rankine Cycle (ORC) and proprietary technologies. As the vapor expands, it drives ElectraTherm's patented twin screw power block, which spins an electric generator and produces emission free power. Run in parallel, the Green Machines in Levice generate approximately 500 kWe.

While combined cycle gas turbines are widely used throughout Europe for power generation and district heating, this is the first application of its kind to utilize ElectraTherm's ORC technology for the lower temperature waste heat. The Green Machines help the site reach maximum efficiency levels through heat that would otherwise go to waste.

ElectraTherm's Green Machine generates power from waste heat on applications such as internal combustion engines, biomass, geothermal/co-produced fluids and solar thermal. ElectraTherm's product line includes units with 35, 65 and 110 kW outputs and offers stand alone or packaged solutions. Read more about Green Machine products at
