The problem
Why factory sheds get so hot
A factory shed collects heat from every side: a metal roof in the sun, machines, motors, ovens and furnaces, and dozens of people working. Hot air rises and stays trapped under the roof, and with poor ventilation the whole floor turns stuffy.
The result is tired workers, more mistakes, more absence and slower output in summer. Air conditioning a large, open shed costs too much to run, and most sheds cannot be sealed anyway.
The system
What a factory cooling system includes
Industrial duct coolers
The main cooling. Each unit pulls hot outside air through wet cooling pads and blows 18,000 to 50,000 m³/h of cooler, fresh air into the shed through ducts placed over the work areas.
Exhaust fans
Push the warm, used air out at the opposite end or high on the walls, so fresh cooled air keeps flowing through. Drop hammer fans in 32, 40 and 54 inch.
HVLS fans
Large, slow ceiling fans that mix the air and keep a steady breeze across the floor. Useful in high-roof sheds and where ducts cannot reach.
Mobile floor fans
Spot cooling for loading bays, furnaces and work cells that move around.
Sizing
How many coolers does a factory need?
Start with floor area. As a first estimate, one 18,000 CMH duct cooler covers up to 1,000 sq ft, a 30,000 CMH unit up to 2,000 sq ft and a 50,000 CMH unit up to 3,000 sq ft. A 20,000 sq ft shed would need around ten 30,000 CMH units, or seven 50,000 CMH units.
High roofs, furnaces, ovens and dense staffing add to that; good exhaust and open doors reduce it. Try the industrial cooler calculator, then send us your layout and we will size the coolers, ducting and exhaust together. Site visits are free in Mumbai and nearby areas of Maharashtra; for other locations a visit fee is charged based on the location.

Getting the best from evaporative cooling
Evaporative cooling works best with air moving through the building: keep some doors, windows or vents open, or fit exhaust fans, so warm air can leave. Place coolers on the side the wind comes from where possible, run ducts low enough to reach the people, and keep the water clean so the pads stay efficient.
In the humid monsoon months the coolers cool less, but they still bring in fresh air; HVLS fans help most then.

FAQ
Common questions
What is the best cooling system for a factory?
For large, open or semi-open sheds, an evaporative system of industrial duct coolers with exhaust fans, plus HVLS fans in high-roof areas, gives the most cooling for the running cost. Air conditioning suits only small, sealed rooms.
How much does factory cooling cost to run?
Each duct cooler runs on a 1.1 to 4.5 kW motor plus a small pump, covering 1,000 to 3,000 sq ft. That is a fraction of the power air conditioning would need for the same floor.
How many degrees will the temperature drop?
It depends on the outside humidity. In hot, dry weather evaporative cooling gives a large drop; in humid weather the drop is smaller. The fresh air and airflow still make the floor far more comfortable.
Do you design and install the ducting?
Yes. We size the coolers, design the ducting and exhaust, and install across India. Site visits are free in Mumbai and nearby areas of Maharashtra; for other locations a visit fee is charged based on the location.
Can the system run on single phase?
Yes. The 18,000 to 30,000 CMH coolers are available in single or three phase. The 50,000 CMH model is three phase only.
