Screened Venting & Cooling all in one!
Evaporative air coolers, also called pad or swamp coolers, have proven to be the most effective cooling system for a greenhouse short of an air conditioner. It pumps water over the special cooling pads which lowers the temperature of air passing through them. A powerful blower pulls air through these pads and pushes the cooled air into the greenhouse. Hot air can be exhausted through roof vents or exhaust shutters and automated with one of our plug-in thermostats. The cooling pads also act as a filter and help keep out unwanted insects, dust, and pollen. Coolers have a 2 speed fan which can be used for ventilation with or without wetting the pads. Coolers come with Aspen pads and a water hose connection kit for constant water supply. Requires a standard 110/120 volt outlet.

How an Evaporative Swamp Cooler Works
Nature's most efficient means of cooling is through the evaporation of water. A simple example is the cooling you feel when stepping out of a swimming pool- the water evaporates quickly from your body, taking heat with it. Our coolers do essentially the same thing by drawing hot air through wet pads using a blower. As water evaporates from the pads, it takes heat from the air with it, resulting in up to 30 degree cooler air being discharged from the cooler.

Cooling Temperatures
An evaporative cooler will normally deliver air cooler than 80 degrees F. In addition, the constant air movement created by the cooler lowers the temperature perceived by room occupants - called the "effective temperature" - by an additional 4 to 6 degrees below actual air temperature. Finally, an evaporative cooler works best in the hottest time of the day. This is because relative humidity drops as temperature increases. For example, a morning relative humidity of 60 percent at 75 degrees will drop to only 31 percent when the afternoon temperature reaches 95 degrees.
