ภายในโรงงานอุตสาหกรรม ที่ต้องมีการควบคุมอุณหภูมิ ไม่ให้มีความร้อนที่สูงจนเกินไป การเลือกใช้ระบบ Evap หรือ Evaporative ในโรงงาน นอกจากจะทำความเย็นให้ภายในพื้นที่แล้ว ยังช่วยประหยัดค่าไฟได้อีกด้วย สำหรับใครที่ไม่รู้ว่า “Evap คือ อะไร”  และมีหน้าที่การทำงานเป็นอย่างไร

วันนี้ Yushi Group จะพาคุณมารู้จักกับระบบ Evap ให้มากยิ่งขึ้น เพราะอะไร ทำไมถึงมีอัตราการใช้ไฟที่น้อยกว่า Air Conditioner และ Evap แต่ละรุ่นมีความแตกต่างกันอย่างไร เพื่อที่คุณจะได้นำไปใช้งานให้เกิดประโยชน์สูงสุด

What is Evap?

Know before implementing an Evap system: How does it work before you miss out!


In industrial factories where temperature control is crucial to prevent excessive heat, choosing to use an Evap system or Evaporative system not only cools the area but also helps save electricity. For those who don't know what "Evap" is and how it works,


Today, Yushi Group will introduce you to the Evap system in more detail. Why does it consume less electricity than an air conditioner? And how do different models of Evap differ so that you can maximize their benefits?


What is Evap?

Evap (Evaporative Cooling System), commonly known as "evaporative fans," is a type of cooling system that can be used in both open and large enclosed buildings to help reduce the temperature inside. The circulating air is natural.

How does it work?

How does it work?


"Evaporative fans" primarily consist of water. The operation begins with water being sent to the water distribution panel to ensure continuous circulation of water.

When the fan blades rotate, it passes hot air through the cooling panel, causing water evaporation to generate cooling without the need for compressors or other cooling lines.

The water inside the water tank remains separate, ensuring that the water does not evaporate quickly. There is a water pump to ensure continuous circulation of water.

If the water level in the tank decreases over time, there is no need to worry about refilling it manually because the machine has sensors to measure the water level for proper operation.

After using it for some time, there is no need to worry about dirty water or unwanted odors because the machine has a drainage system to prevent dirt or dust, ensuring no clogging and maintaining efficient cooling production.


How many models are there, and what are the methods of creating cool air?

How many models are there, and what are the methods of creating cool air?



There are a total of 3 models of Evap fans available, each of which operates on the same principle but differs only in the direction of air distribution: side, bottom, and top. This depends on the installation area and the aesthetic preferences for installation. There are two main methods of creating cool air:


  • Spot Air Cooling: This method directs cool air to a specific point, often used for machinery that doesn't require frequent movement to reduce heat without dispersing it to nearby working areas.


  • Space Air Cooling: This method spreads cool air throughout the entire area, suitable for buildings where people or machinery need to move frequently. When used in conjunction with large fans, it helps distribute cool air over a longer distance.



Regarding the cleaning frequency of Evap fans

Regarding the cleaning frequency of Evap fans, it depends on the working environment. Typically, they are cleaned twice a year, but for enhanced cleanliness, it can be done up to four times a year. This not only ensures a clean and odor-free system but also improves airflow efficiency.

Benefits of using the Evap system:

Benefits of using the Evap system:


  • Energy savings: Compared to air conditioners, Evap systems consume less electricity while providing the same level of cooling, thus reducing electricity costs.

  • Environmentally friendly: Since Evap systems primarily use water, they do not use harmful refrigerants, contributing to environmental protection.

  • Temperature reduction: Evap fans help reduce temperature by trapping heat with tiny water droplets and creating circulated air within the building.

  • Reduced maintenance costs: Evap systems have a lifespan of up to 10 years, with minimal maintenance costs compared to air conditioners.

Why install Evap fans or the Evap system?


Evap fans or Evap systems can reduce temperatures by 4-10 degrees Celsius (for dry and hot areas) and utilize natural airflow, making them suitable for both open and enclosed buildings. They also save costs in various aspects, such as lower energy consumption compared to air conditioners and reduced maintenance expenses. Therefore, they are a cost-effective solution for projects or tasks with budget constraints and efficient cooling needs.


For those interested in installing Evap fans with comprehensive services, including design, installation of both ducts and fans, and after-sales support, it is recommended to choose services from Yushi Group.


To install a comprehensive Evap system, you need Yushi Group.


Yushi Group specializes in the distribution, design, and installation of products related to air ventilation fans to reduce temperatures in areas, facilitating air circulation and eliminating unwanted odors. They offer a variety of industrial fans, including:


  • Giant fans: They provide structural inspections before installation and ensure proper installation according to standards, ensuring user safety.
  • Industrial fans: Available in various types suitable for different purposes, such as farm fans, propeller fans, drum fans, and more, all meeting standard specifications.
  • Mist fans: These high-quality fans are also compliant with standard specifications. They are easily movable, equipped with water tanks, and can operate continuously.

When used in conjunction with an Evaporative Cooler system, they effectively reduce accumulated heat in the area, ensuring proper air circulation within the building. They can cover an area of up to 1,600 square meters and help save energy as well.
