The eco-Air Double Stack V Series Dry Fluid Cooler is a high capacity dry cooler designed to maximize heat rejection capability for a given footprint.  The Double Stack units will help reduce total quantity of units required and installed footprint to optimize the layout on large projects where multiple smaller air-cooled units may be required.

Unlike other dry coolers currently on the market, the EVAPCO eco-Air Series units are 100% fully rated for dry performance. Every eco-Air unit is tested per CTI ATC-105DS and comes with EVAPCO’s exclusive 100% thermal performance guarantee, ensuring peace of mind in selecting the ideal cooling solution for your needs.

  • Runs 100% dry
  • Ranging in nominal heat rejection capacity from 2,750 MBH to 8,440 MBH
  • Type 304L stainless steel tubing as standard
  • Heavy gauge aluminum fins as standard
  • Simplified maintenance
  • NEMA belt drive

Double Stack Dry Principle of Operation


Hot process fluid enters the inlet header connections, shown in red.  Heat from the fluid dissipates through the coil tubes surface and out to the fins.  Ambient air is drawn in over the coil surface by the fan located at the top of the unit.  Heat from the process fluid transfers to the air and discharges to the atmosphere.  Cool process fluid exits the unit through the connections on the outlet headers shown in blue.
