M701J Series
The M701 J Series incorporates more than 40 years of gas turbine design, resulting in a high-capacity gas turbine for 50 Hz power generation. With state-of-the-art technologies, they operate at a turbine inlet temperature of 1,600°C.
The M701 JAC Series gas turbines adopt air cooling and advanced thermal barrier coating on the turbine blades. This gas turbine provides lower levels of NOx, CO2, UHC and VOC emissions. Replacing older coal-fired turbine technology with the new JAC can cut CO2 emissions by nearly 70 percent.
