1. Outdoor air is cooled by Evaporative Cooler (located outside) and discharged into greenhouse.
2. Hot air is exhausted through outlet shutters which operate automatically on pressure differential.
3. Temperature inside house can be as much as 10 to 15 degrees cooler than outdoor temperature with properly designed system.
4. Evaporative Cooler is controlled by thermostat.
5. System efficiency can be increased with the use of shade system. The fans will not have to work as hard to maintain the desired temperature.
6. Since this is a positive-pressure cooling system, you must have sufficiently sized outlets to exhaust air from the greenhouse. This is done by matching the CFM rating for the your evaporative cooler to the CFM rating for one or more outlet shutters. Click here to view our motorized outlet (inlet) shutters.

7. Match sizing data to Cooler Model CFM ratings from drop down list above.
