The system consists of cooling pad, exhaust fan, a water supply and return system,and electric control system. The evaporation of water is used to humidify and cool the air through the principle of heat and humidity exchange. The system sends water to the top of the wet curtain through a circulating water supply, which evenly wets the entire wet curtain wall. When the air passes through the wet curtain, the water is in full contact with the air, so that the temperature of the air is reduced to achieve the purpose of cooling.
Made of fiber, strong water absorption, non-perishable, installed along the full length of the wall, the width is generally 1.5m. Compared with traditional cooling methods, the use of wet curtains can be more energy saving and environmental protection. The cooling effect of the wet curtain completely depends on the principle of natural evaporation, and does not require a lot of electricity and fuel, so it does not produce a lot of carbon dioxide and exhaust gas.
1. Corrugated Paper
Made of fiber, strong water absorption, non-perishable,
2. Water Circulation System
Water is pumped from a tank, distributed over the pad, and recirculated.
3. Control Panels
Automated systems with sensors and timers make the cooling process efficient and consistent.
Greenhouse exhaust fan, for plant growth has the role of drainage, cooling and ventilation. The main structural components are impeller, shell, bracket, motor and so on. The common size is 1380 type and 1500 type. There are 2 models of pushing and pulling and heavy hammer fan , from the opening mode of the blade fan.
Understanding the core components of an exhaust fan can help in both the selection and maintenance of the fan.
1.Motor: The motor powers the fan blades. Typically, motors in greenhouse exhaust fans are energy-efficient, designed to run for long periods without overheating.
2.Fan Blades: These are responsible for moving the air. The design and material of the blades affect the fan's efficiency.
3.Housing and Frame: The casing holds all the components together. The housing is usually made of durable material to protect against external elements.

The cooling pad and exhaust fan work in a synergistic manner to maintain the ideal greenhouse environment:
Warm air from outside the greenhouse is drawn through the cooling pads, which cool the air through evaporative cooling.
The cooled air then enters the greenhouse, providing a fresh and cooler environment for the plants.
At the same time, the exhaust fan removes hot air from the greenhouse, preventing heat buildup and ensuring continuous airflow.
This combination of cooling pads and exhaust fans ensures that the temperature and humidity inside the greenhouse stay within a range that promotes healthy plant growth, making this cooling system an essential feature in modern greenhouses.
Greenhouses are designed to protect crops from unfavorable weather and to extend the growing season, but they can easily become overheated, especially in hot or sunny climates. Without proper temperature regulation, the internal environment can quickly exceed the optimal range for plant growth, leading to heat stress, wilting, reduced photosynthesis, and even crop loss. Many crops, particularly fruits and vegetables, are highly sensitive to temperature fluctuations. Therefore, implementing reliable cooling systems is essential to maintaining a stable and productive environment.
Equipping greenhouses with cooling systems provides numerous advantages for crop production. First, it allows for precise climate control, which is vital for high-value crops like tomatoes, peppers, and leafy greens. With consistent temperature and humidity levels, plants experience less stress and grow more uniformly, leading to better yields and improved quality. Additionally, reduced heat levels help prevent common problems such as flower drop, poor fruit set, and pest infestations. Cooling systems also make it possible to grow crops year-round, regardless of seasonal temperature extremes, maximizing land use and profitability.
Cooling systems using fans and wet curtains are not only effective but also energy-efficient. Compared to mechanical air conditioning systems, evaporative cooling uses less electricity and relies on water evaporation—a natural and sustainable process. This makes it an eco-friendly option for greenhouse operators who are seeking to reduce energy costs and environmental impact. Moreover, the improved plant health and higher productivity contribute to more sustainable agricultural practices, as growers can produce more with fewer inputs and less risk of crop failure.
Why do we recommend our customer this cooling pad wet curtain and exhaust fan greenhouse cooling system？
It is one of the most used greenhouse cooling methods in summer, its installation is simple, low cost, easy operating, long service life, especially good cooling effect, now is widely promoted. At the same time in use should also pay attention to check the water quality, the water pipe must be installed high-quality filters, so as not to affect the cooling effect
The wet curtain has small wind resistance, high evaporation efficiency, and can withstand higher overflow wind speed, so that the wet curtain per unit area can make more air pass through and cool down. A well-maintained wet curtain cooling system guarantees 75-80% cooling efficiency year after year.
The air entering the greenhouse through the wet curtain is more fresh and moist, more suitable for crop growth.
The cooling pad wet curtain exhaust fan system provides a simple and cost-effective way to cool down, and the required mechanical part is only the pump and exhaust fan. Combined with the screening system, the cooling effect is better.
In modern greenhouse agriculture, managing internal temperature is crucial for healthy plant development and optimal yields. Cooling systems such as fans and wet curtains offer a cost-effective and environmentally friendly solution to heat management. By adopting these technologies, greenhouse growers can ensure a more controlled climate, enhance crop performance, and support sustainable food production.
