Low temperature heat-to-power ORC unit LT-180

The low-temperature module converts heat of hot water into electric power. This system suits a wide range of heat recovery applications such as biomass boilers, gas engines, geothermal sources, or industrial processes. Any heat flow with temperatures between 70°C and 120°C can be recovered with this system thanks to its two kinetic turbines.

In case of CHP, heat is delivered from an engine jacket cooling or from exhaust gases of a gen set to the ORC module via a preheater/evaporator unit, which cools the hot water in a primary circuit. Steam enters a twin-turbine device, the main unit of an ORC system, in which steam is cooled down. The released energy is converted into the rotation energy. After steam has passed through the turbine device, it enters a separator and then a condenser, where it condenses. The condensation heat of the working fluid is removed to an air-cooled condenser. ORC modules allow to increase electric power of a power plant to 8%.

Plug-and-play system as a single skid. From the client it's required a minimum of resourses to install, just a foundation, 2 pipes and a cable .
