What is an industrial cooler
Fresh, cooler air for large spaces at a fraction of AC running cost
An industrial cooler, also called an industrial air cooler, pulls hot outside air through wet cellulose cooling pads. As the water evaporates it takes heat out of the air, and a large axial or centrifugal fan pushes that cooler, fresh air into the factory, warehouse or shed.
Because it uses only a fan and a small water pump, with no compressor or refrigerant, an industrial cooler can cool large, open or semi-open spaces that air conditioning cannot handle economically. It works with doors, windows and roof vents open, and it replaces stale, hot air instead of recirculating it.
E-Cool manufactures industrial coolers at MIDC Murbad, near Mumbai: modular duct coolers from 18,000 to 50,000 CMH, a stainless steel model for harsh sites, a centrifugal blower cooler, and wheeled coolers for open areas and events.

How many industrial coolers do you need?
For duct coolers, catalogue coverage is the starting point: one 18,000 CMH unit covers up to 1,000 sq ft, 22,000 CMH up to 1,200 sq ft, 25,000 CMH up to 1,500 sq ft, 30,000 CMH up to 2,000 sq ft and 50,000 CMH up to 3,000 sq ft.
Roof height, the heat given off by machines and furnaces, how many people work in the space and how well hot air can escape all change the final count. Use the duct cooler calculator for a first estimate; our team confirms it on a site visit. Site visits are free in Mumbai and nearby areas of Maharashtra; for other locations a visit fee is charged based on the location.
Where they work

Production floors, forging, fabrication and assembly lines where heat slows people down.
Warehouses and logistics
Large floors and loading bays, often paired with HVLS fans to spread the cool air.
Greenhouses and poultry
Cooling pad walls and exhaust fans for controlled growing and poultry houses.
Events and tents
Garden, tent and blower coolers for pandals, weddings and exhibitions.
Kitchens and restaurants
Spot cooling and fresh air for commercial and cloud kitchens.
Institutions and halls
Ducted cooling for halls, schools and places of worship where AC is too costly to run.
Why E-Cool
Buy from the manufacturer
Made in our own factories
Industrial coolers are manufactured at our two plants in MIDC Murbad, near Mumbai, so you deal with the maker, not a trader.

Single or three phase, with VFD
Motors from 1.1 to 4.5 kW in single or three phase, with single speed or VFD variable speed control.
Installed and serviced
Our team designs ducting, installs, commissions and services the system, with spare parts for the life of the coolers.
Supplied across India and abroad
Installations and dealers across India, exports to Africa, the Middle East and Latin America, and registered on GeM for government buyers.
Since 2009
Manufacturing and exporting evaporative cooling products since 2009.
Industrial cooler or AC?
When an industrial cooler is the better choice
| Industrial cooler | Air conditioning | |
|---|---|---|
| How it cools | Evaporation through wet pads; fan and small pump | Compressor and refrigerant |
| Air | 100% fresh outside air, doors can stay open | Recirculated air in a closed room |
| Running cost | Low: 1.1 to 4.5 kW for 1,000 to 3,000 sq ft per unit | High for large or open spaces |
| Best climate | Hot and dry to moderately humid | Any, including very humid weather |
| Best for | Factories, warehouses, sheds, semi-open areas | Offices, server rooms, sealed spaces |
In very humid weather an evaporative cooler cools less, because the air cannot take up as much water. For most of India's hot season, and for any space that cannot be sealed, an industrial cooler gives far more cooling per rupee.
FAQ
Industrial Coolers: common questions
What is an industrial cooler?
An industrial cooler is a large evaporative air cooler for factories, warehouses and sheds. It draws hot air through wet cooling pads, cools it by evaporation and blows fresh, cooler air into the space using a fan and a small pump instead of a compressor.
How much area does one industrial cooler cover?
E-Cool duct coolers cover up to 1,000 sq ft (18,000 CMH) to 3,000 sq ft (50,000 CMH) per unit. Roof height, heat load and ventilation change the count, so we confirm it on a site visit.
Is an industrial cooler better than AC for a factory?
For large, open or semi-open spaces, yes in most cases: it costs far less to run, brings in fresh air and works with doors open. AC is better for small sealed rooms or where humidity must be controlled.
How much water does an industrial cooler use?
E-Cool duct coolers use about 10–15 litres an hour (18,000 CMH) up to 25–30 litres an hour (50,000 CMH), depending on heat and humidity.
Do industrial coolers need three-phase power?
No. The 18,000, 22,000, 25,000 and 30,000 CMH duct coolers come in single phase (220 V) or three phase (415 V). The 50,000 CMH model is three phase only.
What warranty do E-Cool industrial coolers have?
Industrial duct coolers carry a 3-year warranty on the body and 1 year on the motor. The motor warranty applies when a phase preventer is fitted.
What is the HSN code for E-Cool industrial coolers?
E-Cool invoices its industrial coolers under HSN 8414 59 30.
Can government buyers order through GeM?
Yes. E-Cool Industries is registered as a seller on the Government e-Marketplace (GeM). Contact our sales team for the listing.
Do you supply outside Maharashtra?
Yes. We have installations and dealers across India and export to Africa, the Middle East and Latin America. Site visits are free in Mumbai and nearby areas of Maharashtra; for other locations a visit fee is charged based on the location.
