EcoCoolers contain an inbuilt fan and evaporative cooling pads.  The evaporative coolers are designed to be externally mounted and should be used as part of a mechanical ventilation system with a paired extract fan.  The standard configuration is down flow, where air is supplied from the base of the cooler into the area that requires cooling.

Configuration Options

Down Flow (18,000m3/hr)        Side Flow (13,500m3/hr)         Top Flow (18,000m3/hr)

A 2-speed wall control is supplied as standard with the evaporative cooler, this is normally connected to a thermostat to give automatic control. There is also a facility to connect to a timer, humidistat and fire alarm contact. An internal relay is also available to drive an external fan. The controller provides an integrated commissioning and maintenance cleaning sequence which provides a fault alarm code. For more details on advanced controls options please visit our Controls(link) product page.

Modes of Operation:

Ventilation Mode: In ventilation mode, the water circulation system is not in operation.  The coolers supply fan is used to bring external ambient air into the building.


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.

Alternative Options

External EcoCoolers are also available in a smaller size (up to 12,000m3/hr), please see the ECP EcoCooler 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 product ranges.

Installation Examples

The external evaporative cooler range is ideal for industrial and commercial environments which require blanket or spot cooling. If you are looking for an external passive system for data centres or air handling systems please see our WetBox product page.
