With more than 400,000 hours of operating experience in power generation applications around the world, Caldwell Energy systems offer proven performance, and are backed by a 3-year warranty. Most systems can be installed and running within 45 days.

Caldwell Energy’s team of highly-skilled engineers and fabricators design and manufacture its systems to exact specifications, using time-proven components. Depending on the project requirements, Caldwell Energy can also handle installation, start-up and ongoing maintenance, as well as supply critical aftermarket parts for all system needs.


Four types of Caldwell energy systems, all completely customizable

Caldwell Wet Compression Technology™

Direct injection of fog into the turbine compressor allows machine intercooling.

PowerFog® evaporative cooling

System of nozzles in the inlet airstream creates a fog of micro-fine droplets for evaporate cooling.

PowerChill® chiller-based turbine inlet cooling

Skid-mounted chillers come factory-assembled and can be pre-charged with refrigerant.

PowerStor® turbine inlet cooling with thermal energy storage

Ice or water is stored in an insulated tank to cool inlet air prior to a combustion turbine.
