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 unit operates completely dry and modulates fan speed as necessary based on process temperature requirements and ambient conditions. When the unit can no longer maintain leaving water temperature set point in dry mode, the spray assist system is actuated. The spray system nozzles spray water away from the coil, cooling the entering air and increasing the heat rejection capability of the unit. The heat from the process fluid transfers to the cooled air and is discharged to the atmosphere. Cool process fluid exits the unit through the connections shown in blue.
Spray Assist System
- Ideal for high ambient dry bulb climates or high-temperature applications
- Copper tubing
- Tangential flow nozzles
- Once-through design
- No cold water basin or pump – eliminates winter operation concerns associated with evaporative equipment
Reduced or Eliminated Water Consumption
Compared to traditional evaporative systems, the eco-Air series will either eliminate or dramatically reduce water consumption. Spray models only use water when the ambient conditions and load require it. Reducing water consumption also reduces the ongoing expenses related with the cooling equipment such as purchasing, treating, and disposing of water. When the eco-Air spray models are used in conjunction with the EVAPCO controls package, water conservation is maximized based on proprietary PLC logic.
The eco-Air Series significantly reduces the maintenance traditionally associated with fully evaporative systems. The eco-Air Spray Cooler is designed as a once through system, meaning it has no pump and no basin to hold water, which further reduces the time required for maintenance. Both NEMA and EC motor options require zero routine maintenance. There are no bearings to grease, belts to adjust, or fans to pitch and balance.
Advanced Motor Technology
Available with Electronically Commutated (EC) or NEMA fan motor designs.
The motors on the eco-Air series are pre-wired at the factory to UL standards, reducing costs associated with field wiring. As standard, all units are wired to a common terminal box. Adding the EVAPCO controls package allows for both single point power supply and complete capacity control.
- Premium efficient direct drive
- Zero maintenance sealed bearings
