EAW-DD Double Stack Dry Cooler

• 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

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.
