Inlet Air Fogging (Cooling) systems using Cat Pumps are common installations in power generation plants throughout the world. High-pressure ultra-pure deionized (DI) water is pumped through high-pressure atomizing nozzles placed in the gas turbine air intake. The nozzles create a fine mist that immediately evaporates – also referred to as flash evaporation – immediately cooling the incoming air. The cooler air increases the mass air flow to improve gas turbine efficiency. These systems are the most economical, efficient choice for gas turbine inlet fogging.

To avoid damage to the internal turbine components, the application uses ultra-pure de-mineralized water as pure as 18 MG/OHM. These aggressive water properties create a harsh environment for the pump and pumping accessories. We’ve worked closely with equipment manufacturers and service personnel at fogging sites to develop the longest-lasting pumps and accessories in the industry. This dedication to quality makes us the most specified brand in gas turbine inlet fogging applications worldwide.

With field-proven dependability in applications around the globe, Cat Pumps provides the best value for gas turbine inlet fogging systems.
