Industrial Water Cooler — Manufacturer & Supplier, India
Vayuvents manufactures Industrial Water Coolers (evaporative coolers) for high-volume factory and warehouse cooling. 5,000 to 25,000 m³/hr, low running cost. IS 3588. Mumbai. Call +91 90961 88703.
An Industrial Water Cooler — the commercial-scale evaporative cooling unit for large factories and warehouses — uses the same principle as a domestic desert cooler but at industrial scale: water is continuously pumped from the sump to the top of cellulose honeycomb pads, flowing down to saturate them, while the fan draws hot outdoor air through the wet pads and delivers cooled fresh air to the building interior.
Vayuvents manufactures industrial water coolers from 5,000 m³/hr to 25,000 m³/hr at our Vasai, Mumbai works. A single 25,000 m³/hr unit can cool 250 to 300 sq m of factory floor area. Multiple units are deployed at regular spacing to achieve uniform cooling across large floor areas.
For a 5,000 sq m factory with 5 metre ceiling height requiring 6 air changes per hour, approximately 1,50,000 m³/hr of cooled fresh air is needed — requiring 6 to 8 units of 25,000 m³/hr capacity. Complementary roof exhaust fans or motorised roof ventilators on the opposite wall exhaust the warm air to maintain positive fresh air circulation.
MS galvanised body, cellulose honeycomb pads, submersible pump, distribution header, and float valve for automatic water level control. Available in wall-mounted and roof-mounted configurations for different factory layouts.
Key Features & Benefits
8 to 15°C Cooling Effect
Evaporative cooling drops air temperature 8 to 15°C below outdoor ambient in Indian summer at 30 to 40% relative humidity — the range covering most of North and Central India during May to July.
90% Lower Running Cost
Evaporative cooler power consumption is 0.18 to 2.2 kW — compared to 2 to 10 kW for refrigerated air conditioning of the same space. Saves 80 to 90% on cooling electricity cost.
No Refrigerant — Eco-Friendly
No HFC refrigerant, no compressor — just water evaporation. Zero global warming potential. No refrigerant handling licence required for maintenance.
Fresh Air Continuous Ventilation
Evaporative cooler continuously introduces fresh outdoor air — not recirculated air like air conditioning. Better indoor air quality with continuous fresh air supply.
Ideal for Open / Semi-Open Spaces
Evaporative cooling works in well-ventilated factories, warehouses, and semi-open spaces where windows and doors are open — unlike refrigerated AC that requires a sealed space.
Simple Maintenance
Cellulose pad cleaning every 3 months, water tank cleaning monthly, motor service annually — no compressor, no refrigerant, no complex maintenance.
Reduces Dust and PM in Air
Water mist from the evaporative pads settles fine dust particles and reduces PM levels in the cooled air — useful in dusty factory environments.
IS 3588 Compliant Fan
Axial fan performance per IS 3588. System designed and tested for Indian ambient temperature and humidity conditions.

FAQs — Industrial Water Cooler
An evaporative air cooler draws hot, dry outdoor air through water-saturated cellulose cooling pads. As the hot air passes through the wet pads, water evaporates — absorbing heat from the air and reducing its temperature by 8 to 15°C. The cooled, humidified air is then blown into the building or space. The process is purely physical — no refrigerant, no compressor, just the natural cooling effect of water evaporation.
In North Indian summer conditions (40 to 45°C ambient, 25 to 35% relative humidity), an evaporative cooler reduces air temperature by 12 to 15°C. In coastal Maharashtra, Karnataka, and coastal South India (32 to 38°C ambient, 50 to 70% relative humidity), the cooling effect is 5 to 8°C — less effective because higher humidity limits further evaporation. Evaporative cooling is most effective in dry climate regions of India.
Yes. Industrial evaporative coolers are ideal for factories, warehouses, and large semi-open spaces where sealed air conditioning is impractical. They require cross-ventilation — hot air must be able to escape from the opposite side of the building as the cooler introduces cooled fresh air. Roof ventilators or exhaust fans on the opposite wall provide this exhaust path. Vayuvents supplies both evaporative coolers and complementary roof exhaust fans for complete industrial cooling systems.
Water consumption is approximately 30 litres per hour per 1,000 m³/hr of airflow — a 12,000 m³/hr industrial evaporative cooler consumes approximately 360 litres of water per hour during operation. This is much less than the water used in cooling towers for refrigerated systems of equivalent capacity. A standard water supply at 2 to 3 bar pressure is sufficient — no special water treatment is required for cellulose pad coolers on municipal water supply.
An air washer and an evaporative cooler use the same basic principle — water evaporation to cool and humidify air — but are designed differently. An air washer is typically a larger industrial unit designed for precise humidity control in textile mills and similar applications, using water spray nozzles and eliminator plates. An evaporative cooler uses cellulose honeycomb pads for more compact, energy-efficient cooling in factories, warehouses, and large buildings. Vayuvents manufactures both types.
Yes. Pad-and-fan evaporative cooling is the most widely used greenhouse cooling system for commercial floriculture and vegetable growing in India. Vayuvents supplies matched exhaust fans (creating negative pressure to draw air through the pads) and cellulose cooling pads for greenhouse pad-and-fan cooling systems — as a complement to the greenhouse exhaust fans in the Vayuvents range.
