200–2000 kW (depending on gas pressure and composition). NOTE In the case of variation in gas flow demand, the TecJet 50 gas control valve is able to respond extremely quickly. The benefits of such fast response result in good engine behavior—low fuel consumption, accurate emission levels, and gas flow that completely matches load demand. -
