Cooling the turbine inlet air - even by a few degrees - can increase power output substantially. To accomplish controlled cooling, turbine manufacturers around the world most often choose Donaldson evaporative coolers or chiller coils as enhancements on the inlet air filtration system.

Heavy fog often causes excessively high pressure drop in gas turbine air inlet systems. Now there's a solution - Donaldson D-Fogª coalescing filters.

D-Fog System Description.pdf

The Donaldson D-Salt™ Accessory Module removes a broad range of water-soluble contaminants, regardless of the ambient humidity or particle size, from the airstream feeding a gas turbine. The Donaldson D-Salt™ is a second stage of filtration that is used in conjunction with a conventional gas turbine air filter assembly. The first stage assembly can be either a static or pulse type system. D-Salt™ is placed downstream from the first stage filter and serves as a barrier to the migration of salt. It has proven to be effective in removing salt from the airstream without regard to the shape, size, or phase of the salt contaminant.
