What Is an Industrial Air Cooler?

An industrial air cooler uses adiabatic (evaporative) cooling to reduce air temperature through water evaporation – with no need for refrigerant gases or sealed environments.

Our systems are particularly effective in open or semi-open workspaces like production lines, warehouses, workshops, and logistics centres; business premises which are often considered difficult to air-condition. Each cooler can serve an area of up to 400 m², delivering consistent airflow while keeping humidity levels balanced for both people and equipment.

Choosing the Right Adiabatic Air Cooler for Your Space

Choosing the right adiabatic air cooler depends on several key factors, including the size of the space, ambient temperatures, and your specific cooling requirements. Larger areas and hotter environments will require a higher airflow capacity to ensure effective cooling performance.

Proper ventilation is also critical to the efficiency of any evaporative cooling system. Our industrial air coolers are most effective in dry, well-ventilated areas where warm, stale air can be expelled, and fresh, dry air continuously introduced. This constant air exchange is essential for maintaining optimal cooling results.

While lowering temperatures, they can slightly increase the relative humidity (by around 5–10%), helping to create a more comfortable and stable indoor environment without causing condensation or damaging equipment and materials.

Air Cooler vs Air Conditioner: What’s the Difference?

The key difference between an air cooler and an air conditioner lies in their cooling method, energy usage, and environmental impact. Unlike traditional air conditioners, evaporative air coolers – also known as adiabatic coolers – do not rely on harmful refrigerant gases. Instead, they use the natural process of water evaporation to reduce air temperature, making them a more eco-friendly and sustainable cooling solution.

Industrial air coolers like those in the our range consume up to ten times less electricity than conventional air conditioning systems, significantly lowering running costs. They also require far less maintenance and are better suited to open or semi-open environments such as workshops, warehouses, hangars, and logistics hubs.

While air conditioners require sealed rooms to function efficiently, portable air coolers are designed to operate with open doors and windows, ensuring continuous airflow. Our adiabatic coolers deliver a steady stream of fresh air that’s 3 to 12°C cooler than the outside temperature, all while maintaining natural humidity levels – helping to improve indoor comfort without drying out the air.
