INDUSTRIAL DIRECT AND INDIRECT/DIRECT EVAPORATIVE COOLING
Engineer designed to satisfy your design requirements.
Modular Components Cost Effectiveness
� Air Handling Modules in side, down or up � Competitive fi rst cost combined with substantial
discharge and single or dual inlet design. energy savings over refrigerated air units results in
quick payback. Plus, the simplicity of design allows
� Evaporative Media Modules with standard 8” or
low maintenance requirements.

2-STAGE INDUSTRIAL EVAPORATIVE COOLING The Indirect Cooling Module Indirect/Direct Evaporative Cooling Process Outside air is drawn into the ICM. A fan In the indirect cooling stage, entering air is cooled along a horizontal draws air through the inside of vertical fi ns humidity ratio line on the Psychrometric Chart (A to B) without adding (which have water running inside them). The moisture. In the next cooling stage, this air is further cooled along a new air picks up heat and is expelle
