How an Industrial Evaporative Cooler Works ?
An evaporative cooler also called a swamp cooler or air cooler which draws warm outdoor air through water-saturated cooling pads. As water evaporates, it absorbs heat from the air, reducing the temperature by 5–15°C depending on ambient humidity. The cooled, humidified fresh air is then pushed through duct outlets into the facility.
Unlike sealed refrigeration systems, evaporative coolers require no compressor and no refrigerant. The only moving parts are a fan and a water pump. This makes them significantly cheaper to install, cheaper to run, and simpler to maintain — at the cost of being most effective in dry climates with low ambient humidity.

Evaporative Air Coolers Application
Warehouse & Distribution Center
For large-span warehouses operating with open doors, evaporative cooling represents an ideal solution. It regulates heat and humidity—while simultaneously eliminating odors generated by stored goods and vehicle traffic—through a continuous process of fresh air exchange.
Manufacturing Factory
High heat from machinery and production processes makes factories a primary application for rooftop evaporative cooling. Koven Air industrial coolers deliver consistent fresh air throughout the facility, cutting heat-related productivity loss at a fraction of AC operating cost.
Gyms & Sports Arenas
Large public venues in hot climates present significant cooling challenges. Wall-mounted evaporative coolers at perimeter positions, combined with rooftop units for general air supply, provide effective and energy-efficient comfort cooling for spectators and athletes in sports and entertainment venues.
Office & Commercial Building
Koven Air rooftop evaporative coolers delivering fresh cooled air throughout occupied zones while reducing cooling energy costs by up to 80% during dry-season operation, operating costs are only 10–20% of those for air conditioning.
More Applications
- Workshops & Garages
- Event Venues
- Restaurants
- Schools & Universities

Powerful Evaporative Cooling Effect
Our exclusively designed evaporating system are engineered for extreme heat environments. Even when outdoor temperatures reach 45°C, they consistently deliver cool air at 25°C — a 20°C drop that keeps factory floors, warehouses, and commercial spaces genuinely comfortable, not just bearable.
The high-density 5090 honeycomb structure maximizes water-to-air contact surface area, achieving superior cooling efficiency while consuming 10–20% less water than conventional cooling pads. Less water used, more cooling delivered.
Evaporative Cooler + HVLS Fan Complete Facility Cooling
A rooftop evaporative cooler lowers air temperature. An HVLS fan moves that cooled air across every corner of the facility. Together, they form a complete cooling system that neither can achieve alone.
The evaporative cooler handles the temperature drop — delivering fresh, cooled air through the duct network. The HVLS fan handles the distribution — its large-diameter, low-speed rotation creates a steady, gentle airflow across the entire floor area, eliminating hot spots and ensuring every worker benefits from the cooled air above.
The result is faster, more even cooling across large spaces, with lower energy consumption than running either system at maximum capacity alone.
Frequently Asked Questions About Evaporative Air Cooler
What is the difference between a rooftop cooler and a wall mount air cooler?
They are actually same thing ,just different mounting structure.
How long of a duct can your evaporative cooler accommodate?
Usually we suggest 20m if it is a axial air cooler , centrifugal cooler will depends on the static pressure.
Do you offer OEM/ODM option for swamp cooler ?
Yes , we do.
How much can an industrial evaporative cooler reduce temperature?
In hot, dry climates with low ambient humidity (below 50–60% relative humidity), an industrial evaporative cooler can reduce air temperature by 5–15°C. The exact cooling effect depends on the local wet-bulb and dry-bulb temperature conditions. In more humid environments the cooling effect is reduced.
What is the difference between axial and industrial centrifugal evaporative coolers?
Axial evaporative coolers use a propeller fan to move high volumes of air at lower static pressure ,centrifugal evaporative coolers use a blower wheel generating higher static pressure, enabling cooled air to travel through long duct runs and reach multiple zones across a large building.
How much energy does an industrial evaporative cooler use compared to air conditioning?
Industrial evaporative coolers typically consume 75–80% less electricity than refrigerated air conditioning for equivalent air volumes in dry climates. The main power loads are the fan motor and water pump ,there is no compressor.
What is the difference between a PMSM direct-drive motor and a traditional AC motor in HVLS fans?
Traditional HVLS fans use AC induction motors with gearboxes which adding maintenance requirements, mechanical noise, and energy loss. Koven Air’s PMSM direct-drive motors eliminate all of that: No gearbox , no oil changing and IE4 highest efficiency, result in lower operating costs, less maintenance, and longer service life
What is the warranty on Koven Air evaporative coolers?
2-year full unit warranty, extendable up to 5 years.
