FlexSpray Dry Coolers

Features & benefits

The FlexSpray Cooling option can be added to single and double coil arrangements. The FlexSpray package is available in various combinations to suit your needs. The system can be fully integrated with step controls or a simple spray system to be controlled manually or by your choice. Existing units either Flex coil or competitors models can also be fitted with the FlexSpray system.

Basic operation, on a fully controlled unit, energizes the electromechanical valve system as the final step in the control sequence to reach the leaving water or refrigerant set point. With a VFD system, once all motors have reached full speed and the set point is not met with air only, the electromechanical valves energize and the spray comes on. The dead band range prevents the valve body from oscillating on and off and allows the spray to run to minimize thermal shocking. Using step control, the electromechanical valve system will energize after the last motor is energized and the set point triggers the valve to open.

FlexSpray selections can be made using the EAS CoilCalc selection program
