Evaporative Cooling Originated in an Ancient Idea

Evaporative Cooling Originated in an Ancient Idea

Evaporative Air Cooler, as the modern industrialized product based on this ancient theory, brings this benefit to every aspect of our life.

People who live in hot areas always find out various ways to cool down the temperature when summer’s coming. Evaporative cooling is one of them, ancient people used this idea to cool the room by pouring water on the reed and putting it up as a curtain. When hot air went through the curtain, the temperature went down.

Nowadays, with the instant technology innovation, the Evaporative cooling pad has replaced the reed and wood wool as the cooling media, to maximize the evaporation area and increase the cooling efficiency.

  • High-efficiency ventilation capacity with lower investment and operation cost;
  • Each motor is individually tested for 100% quality control;
  • Galvanized steel Fan housing and Shutters to ensure the highest strength;
  • Italy imported V-type belts with high quality and durable;
  • The 6-bladed propeller is made of stainless steel or aluminum alloy;
  • A powerful couple of Mass keeps the shutter firmly closed when the fan is not operating.

Time to Upgrade your Ventilation

Still, ventilating with rows of small wall fans? For customers who are using dozens or hundreds of small wall-mounted fans, we will provide a detailed ventilation cooling solution.

Core Technology

High Cooling Efficiency

Using space cross-linking technology, it has high absorption and long service life. Large evaporation surface area, cooling efficiency as high as 80%.



RTFANS's cooing pads are eco-friendly for use.

Cooled by Evaporation

The pump circulates water from the water tank onto a cooling pad, which in turn becomes very wet. A fan draws hot air from the outside of the unit through the moistened pad. As it passes through the pad the air is cooled by evaporation, and then is pressured out by a ventilator.

An Evaporative air cooler can be installed on the roof, wall, or ground, wherever suitable.


When cooled air is blowing into the building constantly by the evaporative air cooler, the hot air inside the building is forced out. And the pressure difference between the inside and outside of the building will lead to continuous air exchange, so a certain quantity of doors and windows shall be kept open to facilitate the air exchange during air cooler operation.


Safety First Industry Standard

Compared with other brands of large HVLS fans on the market, all the fans we produce have passed the high-strength crash test, the fans will not fall off, and the blades will not break.
Just like our manufacturing requirements, protecting people, products, and property from harm is our number one priority, so our HVLS fans are not responsible in the event of an accident or emergency.


Since plants and animals are very sensitive to changes in temperature and humidity, heat stress has a huge impact on growth and development in agricultural and farming applications.

The evaporative cooling pad system, as one of the most efficient and economical cooling ways for agricultural and breeding applications, provides an ideal temperature and a comfortable environment during the hot summer.


The ventilation fan and cooling pad frame shall be installed on a different wall side to ensure fluent airflow.

The air is exhausted during the ventilation fan’s operation, which creates a negative pressure inside of the building, then air from the cooling pad frame side will flow into the building to keep the pressure balance. When air passes through the cooling pad which is filled with water, the temperature of the airdrops is due to evaporation in the process.
