Mueller Environmental Designs “Kool Pak” evaporative cooler is custom designed to provide maximum cooling performance with 95 % to 98 % saturation efficiencies. The Mueller “Kool Pak” provides economical air cooling with low initial, operating and maintenance costs by capitalizing on the basic advantages of evaporative cooling.

Evaporative cooling involves heat and mass transfer by lowering the dry bulb temperature of air through the evaporation of water. It is an adiabatic process by which sensible heat of the inlet air is exchanged for the latent heat of water through evaporation. As inlet air passes through the wetted rigid media blocks, water evaporates absorbing energy while changing from liquid to vapor state, and removing heat from the inlet air, which lowers dry bulb temperature. This process increases the moisture content of the air, raising the inlet air saturation percentage.

The Kool-Pak evaporative cooler is heavy duty all welded construction and can be used for

• Gas Turbine inlet air cooling
• Reciprocating Engine air inlet cooling
• Generator and motor room cooling
• Total Area cooling
• Spot cooling
• Humidification
