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.
Wetted pads can be utilized for pre-cooling entering air, resulting in greater energy savings and increased capacity with minimal water use. This system is ideal for high dry bulb climates or high temperature applications. It features a once-through design with no water treatment required, no cold water basin or pump, and no drift.
Compared to traditional evaporative systems, the eco-Air series eliminates or significantly reduces water usage. Adiabatic models only use water when ambient conditions and load demand it. This leads to reduced expenses in purchasing, treating, and disposing of water. When used with the EVAPCO controls package, water conservation is optimized through proprietary PLC logic
.The eco-Air Series minimizes common issues like scaling, corrosion, and water-borne bacteria. As a once-through system, it requires no pump or basin, significantly lowering maintenance needs. Adiabatic pads also act as air filters, limiting debris buildup on the coil surface. Both AC and EC motors are enclosed, eliminating the need for greasing, belt adjustments, and fan balancing.
Available with Electronically Commutated (EC) or Alternating Current (AC) fan motor designs, the motors are pre-wired at the factory and connected to a common terminal box for quick installation. When integrated with the EVAPCO controls package, they support single-point power supply and full capacity control.
Highly efficient direct drive motors, VFD-ready, and suitable for severe-duty environments.
