Huadian, a power generation company located in China, upgraded the air inlet filtration system to the GTC synthetic cartridge filters on GT PG9171E engines and improved pressure drop and availability despite the high humidity levels.
After three years of operation the CamPulse GTC F9 cartridge gas turbine air filters helped improve power output, decrease filter replacement frequency, and save over $400 000 as a result of lower pressure drop.
