What Is Industrial Evaporative Cooling?
March 16, 2023

Industrial evaporative cooling, also known as EVAP, is a process that uses the natural cooling process of evaporation to lower the temperature of the air. It is a cost-effective and environmentally friendly alternative to traditional air conditioning systems and is particularly effective in dry, hot climates. EVAP systems are commonly used in industrial facilities such as factories, warehouses, and power plants to improve the comfort of the employees working in the space and increase the overall efficiency of the operation.
What Is Industrial Evaporative Cooling?
- Air is drawn through wet pads or media: In an EVAP system, air is drawn through wet pads or media, such as cellulose, paper, or fiberglass. As the air passes through the wet pads, it becomes cooled by the process of evaporation. The cooled air is then circulated throughout the facility, helping to lower the overall temperature.
- Water is continuously circulated: To maintain the effectiveness of the system, water is continuously circulated through the wet pads or media. This helps to keep the pads or media wet, which is essential for the cooling process. The water can be cooled using a variety of methods, including ice, refrigerant, or chilled water.

Advantages of Industrial Evaporative Cooling:
- Cost-Effective: One of the main advantages of EVAP systems is that they are more cost-effective than traditional air conditioning systems. They use less energy and have lower upfront costs, making them an attractive option for businesses on a tight budget.
- Environmentally Friendly: EVAP systems are also more environmentally friendly than traditional air conditioning systems. They do not use refrigerants, which can be harmful to the environment if released into the atmosphere. In addition, EVAP systems use water as a coolant, which is a natural and renewable resource.
- Increased Comfort: Another benefit of EVAP systems is that they can provide a more comfortable working environment for employees. Traditional air conditioning systems can often make the air too dry, leading to discomfort and respiratory issues. EVAP systems, on the other hand, add moisture to the air, which can help to improve air quality and reduce the risk of respiratory issues.
In conclusion, industrial evaporative cooling, or EVAP, is a cost-effective and environmentally friendly way to cool industrial facilities. It works by using the natural cooling process of evaporation to lower the temperature of the air and is particularly effective in dry, hot climates. EVAP systems have lower upfront costs and energy consumption compared to traditional air conditioning systems and can provide a more comfortable working environment for employees.
