Evaporative cooling and humidification

The VapaWall wetted media from Vapac has been designed to provide humidification and evaporative cooling within an air-conditioning system. It can be used in data centres to deliver low-cost and reliable low-energy evaporative cooling or in an air-conditioning environment to provide humidification and supplement mechanical chillers for new installations, as well as retro-fit or refurbishments.

VapaWall has a cassette-based modular construction and can be built to suite any air handler. The wetted-media cassettes are constructed of an inorganic material supported above a stainless-steel water tank by a rigid frame.

The supply of water into the tank is controlled automatically via a solenoid inlet valve and optional inlet filters. A proportion of water is drained away to restrict mineral concentration.
