In 1999 a great Dutch inventor/scientist, dr. Gus Witteveen, approached us with a really revolutionary idea for a highly energy-efficient microturbine. This turbine concept, not bigger than a fist, would meet the highest thermal efficiency in it’s class. Up to 40% was theoretically possible. This is astonishingly high for small turbines normally not exceeding a few percent. Most engineers didn’t believe it was possible because in small turbines all kind of drag & wear losses prevail. But Witteveen took another, unconventional, approach and after a few years succeeded. The feasibility tests were so promising that investors took over and a company MTT (Micro Turbine Technology) was erected. Now, after 15 years of technological and market development a succesfull product exists: EnerTwin.
The EnerTwin is a micro CHP (Combined Heat and Power) system where a boiler and a small power plant are combined in a single durable device. The heart of the EnerTwin is a micro turbine that drives a generator. The micro turbine delivers 3kW electrical power and 14.4kW thermal power for heating and hot tap water. Up to 19% thermal efficiency is reached (source: Micro Turbine Technology).
The EnerTwin is a cogeneration system based on this micro total energy turbine concept. Micro turbines offer great advantages in reliability, life and maintenance costs.
