Product Description

Pad and fan greenhouse cooling systems



1.Working Principal


Fans/wetting pad cooling system can decrease the temperature according to the principle of evaporation of water for cooling. System has high-quality wetting pads and the fans with big wind.

The core of cooling system is the wetting pads, which can evaporate water, is made of corrugated fiber paper.it is corrosion resistant and has long working life, because the raw material is added to a special chemical composition. The special wetting pads can ensure the water wets whole wall of wetting pads. When the air goes through the pads, the exchange of water and air on the surface of pads can change the hot air into cool air, then it can humidify and cool the air.

When you need to cool down, start the fans, and be forced out of the air inside the greenhouse to cause negative pressure; at the same time, the water pump will spring water to the opposite wall of wetting pads,then the outdoor air is sucked into the greenhouse by negative pressure, and the air will go through the pads slowly, which can lead to evaporation of water. The cooling air comes into greenhouse and absorbs the indoor heat, and then discharged by fans. So the temperature in the greenhouse will drop down.

The system uses aluminum frame,so it has beautiful shape and is not easy to be out of shape.

2.Water supply system

Water supply system includes submersible water pumps, shunt water pipe, main water supply pipe, water distribution pipe and water separating equipment, etc. as well as the necessary regulating valves. The main water supply pipe, water distribution pipe are special material UPVC with long service life.

3.Water Collecting system

The water collecting system includes water collecting grooves and water return pipe, which is made of UPVC. Each section of wetting pad has one spot of water return and all water flows to the main return pipe, at last discharges to the collecting pool.




Performance features:
 1)After special treatment, the corrugated paper of the cooling wall has high strength, excellent anti-corrosion and long service cycle;

2)It has remarkable permeability and water absorptivity, so it can guarantee that the water is evenly drenched through the entire cooling wall.

3)Specific 3D space structure can provide the maximum evaporating surface for the heat exchange between water and air;

4)Outline frames of aluminum alloy and galvanized plates are available for choice.



4.Cooling pad advantages :
1)High water absorbtivity
2)Prevent algae growth
3)Mould resistance
4)High cooling efficiency
5)Long service life of cooling pad
