Industrial Evaporative Cooling

Make Up Air: EC Series

We Make It Better

Have you ever noticed how cool it feels near a waterfall on a hot summer day? That’s evaporative cooling: the reduction in air temperature that occurs when water evaporates. Our customers, including the majority of Fortune 500 companies, are cooled efficiently using our patented evaporation cooling process. We provide engineering solutions internationally in every industry and environment.

Highest Air Purity

When air purity matters,nothing beats our patented Freshwater® Slinger design for evaporative cooling.

EC Series Make Up Air

The EC Series Make Up Air is available as a direct, indirect, hot-water, steam, electric coil and heat recovery modules.

Available from 2500 CFM to 100,000 CFM in the following blower modules:

  • DWDI Forward Curve Centrifugal
  • DWDI Airfoil Backward Curve
  • SWSI Backward Curve Plenum

Available in vertical and horizontal configurations
