Direct Evaporative Cooling Process
MasterCool Evaporative Media
Direct evaporative cooling exchanges sensible heat for latent heat, 
MasterCool evaporative media is constructed 
and follows upward along a constant wet-bulb temperature line on the 
of special cellulose material, impregnated with 
insoluble anti-rot salts and rigidifying saturants.

Standard and Hi-Performance Models
The fl exibility of modular components allows selection of CFM and 
saturation effi ciencies producing the sensible heat capacities needed to 
meet design requirements. For 
many applications, our standard 
8” media continues to be an 
economical choice, with an 80% 
saturation effi ciency at 450 FPM. 
For more demanding design 
conditions, our 12” media offers 
90% effi ciency at around 450
