How It Works

Warm process fluid is circulated through the coil on the cooler

Cool ambient air is drawn across the coil drawing heat out of the fluid, rejecting it to the surrounding air.

Cooled process fluid is returned to the system reservoir.

When the ambient temperature is slightly above the desired process temperature, the cooler automatically switches to its adiabatic pre-cooling mode.

The pre-cooling media is wetted and as air is drawn across the wetted media water evaporates cooling the air before it reaches the coil.

In the adiabatic mode, the cooler can maintain fluid temperatures low enough to provide hydraulic and other process cooling even at ambient temperatures exceeding 95°F.

Control is automatic. The unit switches from dry to wet mode to minimize water use. The fan motor is equipped with a variable speed drive for maximum energy savings.

The coils drain to an indoor reservoir when cooling is no longer required.
