A 450 litre tank is purely industrial. 8 verified models sit in the 430–470 litre band, every one of them a Ram Coolers machine, from the ₹41,000 IND 1500 to the ₹78,500 IND 2200H, median ₹58,000.
All 8 use honeycomb pads and carry rated power between 500 W and 800 W — about ₹7,200 to ₹11,520 a year at ₹8 a unit over ten hours a day for a 180-day season. That is the running cost of cooling a factory bay for a year.
A tank this size exists so the machine runs an entire shift, and often two, without anyone refilling it. It says nothing about how much air the cooler moves. Specify on airflow: required m³/hr = floor area sq ft × ceiling height ft × air changes per hour ÷ 35.315, using 60 air changes an hour for a factory floor.
Evaporative cooling at this scale needs a genuine air path out of the building. Sealing a shed and running a 450 litre cooler inside it will raise humidity and stop the cooling.

How we chose these
Specify on airflow
These are sized by m³/hr against your floor area and air changes per hour, never by tank litres.
Plan the water supply
At industrial airflow a 450 litre tank still empties. Check whether the model takes a permanent water connection rather than manual filling.
Exhaust path
60 air changes an hour only happens if the air can leave. Budget for ridge vents or exhaust fans alongside the cooler.

Frequently asked questions
How many 450 litre air coolers are verified here?
8, all from Ram Coolers, in the 430–470 litre band, ₹41,000 to ₹78,500.
What does a 450 litre industrial air cooler cost?
From ₹41,000 for the Ram Coolers IND 1500 to ₹78,500 for the IND 2200H, on the manufacturer's own published prices.
How much electricity does one use?
Rated power runs 500 W to 800 W across these 8 models — roughly ₹7,200 to ₹11,520 a year at ₹8 a unit, ten hours a day for 180 days.
Is a 450 litre cooler better than two 200 litre ones?
Not automatically. Two smaller machines placed where people work often cool a floor better than one large machine in a corner, because evaporative cooling is felt locally. Compare total airflow and placement.
Do these work in humid climates?
Poorly. Evaporative coolers depend on dry air. In coastal or monsoon conditions the temperature drop is small regardless of machine size.
