External WetBox – Large
90% more energy efficient than traditional refrigerant air conditioning
External WetBox – Large
The WetBox evaporative cooler contains inbuilt evaporative cooling pads.
The EcoCooler Wetbox should be used as part of a mechanical ventilation system or air handling solution with a paired supply and extract fan.They are designed to be externally mounted and the standard configuration is down flow, where air is supplied from the base of the cooler into the area that requires cooling.
Control
An output is offered to communicate the state of the cooler. An input is available to enable and disable cooling in the evaporative cooler.
Modes of operation
Cooling Mode
In cooling mode, the water circulation system is in operation and the cooling pads are wetted. The evaporation of water from the pads results in a reduction in air temperature. Additional extract and supply fans are used to draw air through the cooler and building.
