Products Description

Working principle:

As schematically shown, when the cooler is working, water is pumped from the tank to the water distributor, and distributed evenly to the evaporative cooling pads, then go back to the tank. Meanwhile, the outside hot air is drawn through the wetted cooling pads and filtered and reduced in temperature before delivering to the user space. 

How does evaporative air cooler work?

Fresh outdoor air is continuously brought into the indoor room through the air duct and air supply outlets after being filtered and cooled by an evaporative air cooler. The indoor environment will be in a positive pressure state due to the constant flow of fresh air, which will cause the initial hot air that included odor and dust to be expelled out of the space and leave behind a cool, ventilated, tidy, and comfortable environment. For any evaporative air conditioning system to operate satisfactorily, a suitable exhaust area and an efficient exhaust are necessary.

Supply Air Temperature

The "dryness" of the outside air determines the supply air temperature. The temperature of the web bulb decreases as the outside air becomes dryer. The ability to reduce temperature is increased.
When the outside air is hot and dry, evaporative cooling performs at its optimum. For information on temperature drop (supplied air temperature with air cooler) under various humidity and temperature circumstances, see the datasheet below.
The secondary cooling effect known as the "wind-chill effect" occurs when air moves over human skin, creating an effect like to that produced by a fan and making it feel cooler. The Supply Air Temperature and Air Velocity both affect the Wind-Chill Effect.


Why Evaporative Air cooler?

  1. 100% copper high-quality motor, With iron casting housing, more durable and steady;
  2. Upgraded high-efficiency cooling pad with fixing frame—Higher cooling efficiency and better protection for the core cooling media;
  3. Integrated one-piece fan blades with patent structure and design, Low noise, and high airflow;
  4. Strong PP engineering plastic structure with Anti-aging and Anti-UV material, long life span;
  5. Vertical water inlet valve to make sure, stable water inlet supply with minimum blockage;
  6. LCD and mechanical control board, optional for auto/mechanical control system;
  7. The open-type water distribution system can make water be distributed evenly onto a cooling pad;
  8. Specially designed air inlet shutter shape to ensure maximum air inlet while can keep rain and dust outside.



An industrial ventilation system is a system that provides fresh air to an industrial environment to maintain a comfortable, healthy, and safe working environment for employees.

An industrial ventilation system works by drawing in fresh air from outside and circulating it through a building while simultaneously removing stale air and pollutants.

Benefits of using an industrial ventilation system include improved air quality, increased energy efficiency, reduced risk of workplace accidents, and improved employee health and productivity.

There are several types of industrial ventilation systems, including natural ventilation, supply ventilation systems, exhaust ventilation systems, and mechanical ventilation systems.

Choosing the right industrial ventilation system depends on a variety of factors, including the size and type of your facility, the types of pollutants in your workplace, and your energy efficiency goals.

Maintenance requirements for an industrial ventilation system include regular cleaning of filters, inspection of fans and ducts, and periodic replacement of worn-out components.

7. Can an industrial ventilation system help reduce energy costs?

Yes, an industrial ventilation system can help reduce energy costs by providing energy-efficient air circulation while also removing heat and pollutants from the environment.

Installation of an industrial ventilation system should be carried out by a licensed and experienced professional to ensure compliance with local regulations and safety standards.
