The WetBox evaporative cooler contains inbuilt evaporative cooling pads and 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.

An input is available to enable and disable cooling in the evaporative cooler. An output is offered to communicate the state of the 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 supply and extract fans are used to draw air through the cooler and building.

Alternative Options

EcoCooling WetBoxes are also available in a smaller size (up to 1,160m3/hr), please see the EcoCooling WetBox Small product page for more details.  Alternatively, if you are looking at an installation where there is no outside plant space, call our installations team for advice about plant rooms or have a look at our ECT internal evaporative cooler product ranges.

Installation Examples

The external EcoCooler evaporative cooling range is ideal for data centre and air handling installations environments which require closer temperature control. If you are looking for an active system (with an inbuilt fan) for industrial or warehouse cooling please see our EcoCooler product pages.
