ElectraTherm, a leader in small-scale, distributed power produced from waste heat, surpassed 30,000 runtime hours on its Series 4000 Green Machine fleet. This is the first Organic Rankine Cycle (ORC) machine sized 30-65kWe to achieve this milestone. The Green Machineís extensive hours demonstrate robust, proven ORC technology as a viable means to increase efficiency and maximize power output.
ElectraThermís fleet consists of 17 commissioned machines; seven in North America and ten in Europe, with numerous installations in process. Applications vary from internal combustion engines to biomass boilers, geothermal/co-produced fluids and solar thermal.
ElectraThermís Green Machine generates fuel-free, emission free power from low temperature waste heat. Hot water enters the Green Machine at between 88-116įC (190-240įF), where it heats a working fluid into pressurized vapor, using ORC and proprietary technologies. As the low pressure vapor expands, it drives ElectraThermís patented twin screw power block, which spins an electric generator and produces up to 65kWe.
ďNothing speaks to proof of commercial viability better than runtime hours on machines in the field; the Green Machineís proof is in the numbers with recent installations achieving greater than 95% availability,Ē said John Fox, Chief Executive Officer of ElectraTherm. ďElectraThermís robust, patented technology gives a whole new value to low-grade waste heat.Ē
ElectraTherm (electratherm.com) will exhibit at Power Gen Europe in the Renewable Energy section, booth number 7D11. The event takes place June 12-14, 2012 in Cologne, Germany. ElectraThermís Series 4000 Green Machine ORC will be on display.
