Greenhouse Megastore Evaporative Cooling Pads are a high-efficiency evaporative cooling media for greenhouses, warehouses, enclosed patios and many other spaces.
Why do you need evaporation cooling pads for your greenhouse?
- Greenhouses can get very hot due to their design. A cooling pad wets the air that passes through with water, cooling it down for a more stable temperature that makes it easier for plants to grow and for workers to toil away inside enclosed greenhouses.
- Our evaporative swamp cooler padding is built for long-lasting and low-maintenance service life. It's constructed with high-absorption cellulose virgin Kraft paper that has a density of 110 grams per square meter. The paper is treated with wetting additives and anti-rot agents for maximum efficiency and longevity.
- High-quality adhesives and rigidifying agents have been added to our pads for increased resistance to wear and tear. Additionally, the air inlet side of the cooling pads is dipped in specialized black plastic resin which helps reduce scaling and mineral buildup.
- Due to mineral buildup, it's recommended that you replace your greenhouse evaporative cooler pad every three to five years. Maintain or upgrade your greenhouse evaporative cooler with these premium single-side swamp cooler pads.
- The 12-inch-wide pads are available in multiple lengths and thicknesses to fit the evaporative systems we sell plus many others from leading manufacturers. Choose from many different sizes for the best fit in 5 or 25-pad package orders. Greenhouse cooling pads are sold with volume discount pricing for commercial and industrial clients.
- The amount of air moved by a fan is proportional to the negative pressure, even when the fan is spinning at full speed. This means that air refreshment doesn't come from the fan speed alone but the fan speed and negative pressure. Each fan has a diagram that shows how much power the fan can do with the negative pressure. Keep in mind when you're planning a ventilation system. Make sure that the fan capacity is calculated with enough negative pressure in mind.

How to maintain the cooling wet curtain?
- Use good water quality:The cooling effect of the cooling curtain is achieved by the circulating water through the wet curtain paper, absorbing the replacement air heat to reduce the air temperature, so the quality of the cooling wet curtain is very important, and better water quality must be selected. The PH of the circulating water is maintained between 6 and 9 (a PH of 7 is pure water). The PH value is too high or too low, it will damage the cooling wet curtain paper;
- Proper water level.The water level inside the cooling curtain sink should be set properly, if the water level is too high, the bottom of the cooling wet curtain paper will be soaked in water for a long time to become over-filled with water, which will affect the circulating water self-contained water system, but also shorten the service life of the wet curtain paper.
- Continuous drainage:Cooling wet curtain in the cooling time of the air, water will continue to evaporate and new water is constantly replenishment, in the water cycle process, salt and minerals are left behind, in order to reduce the formation of precipitation and scale, need an automatic drainage device, because the drainage rate is 5% to 10% of the evaporation rate, and the evaporation rate mainly depends on the hardness of water and air pollution level. The drainage rate under normal operation should be 20% of the maximum evaporation rate under poor conditions.
- Correct cleaning wet curtain system:
Cooling wet curtain paper will filter the dust in the air, long-term use, you need to clean the settled dust and dirt, you can spray with low pressure water vapor or gently wash the wet curtain paper, or use an electric fan along the corrugated cooling wet curtain paper diagonal blow to remove foreign matter and dust. It is also necessary to regularly clean the pool, pump inlet, filter and water pipe, etc., to remove the dirt inside the water circulation system. Remember not to use chemicals such as chlorine or other pungent smells to clean. - Shutdown maintenance:
The cooling wet curtain should be maintained regularly, at least at the end of each quarter, drain the water in the water pump, sink, water storage room and cooling wet curtain paper in the cooling wet curtain system. If some water remains in the system, it will accumulate, precipitate and produce algae, etc., which will block the pump, the water supply pipe orifice and the hole in the cooling wet curtain paper when the next time is used. In winter or when the cooling wet curtain system is not used for a long time, the surface of the cooling wet curtain should be covered with a layer of plastic film or cardboard to avoid dust and oil erosion of the cooling wet curtain paper.
