Adiabatic

The eco-Air Double Stack Adiabatic Fluid Cooler is a high capacity adiabatic 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. The adiabatic pre-cooling system with 2-stage operation as standard
minimizes water usage and can provide leaving water temperatures comparable to evaporative units. 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.

• Dramatically reduced water consumption
• 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
• AC/NEMA Belt drive

Eco-Air Solutions – Adiabatic Cooler by EVAPCO

Hot process fluid enters the inlet header connection, shown in red. Heat from the process fluid dissipates through the coil tubes surface and out to the fins. The adiabatic system involves fully wetting a fibrous pad located in front of the coil. Ambient air is drawn through the adiabatic pre-cooling pad by the fans located on top of the unit. The air is humidified as it passes through the adiabatic pad, decreasing the ambient dry bulb temperature within a few degrees of the ambient wet bulb temperature. This new air temperature is referred to as the depressed dry bulb. This pre-cooled air is then drawn through the tube and fin surface, offering a substantial increase in heat rejection capability. Heat from the process fluid transfers to the air and is discharged to the atmosphere. Cool process fluid exits the unit through the connections shown in blue.
