Catalogue listing — not a hands-on review
We have not tested this unit. The specifications below are parsed from the manufacturer's own listing, the features are their wording, and the score is calculated from those specifications rather than assigned by an editor. For models we have examined in depth, see our ranked refrigerator guides.
About this model
The Crompton Optimus 65 IoT is a desert air cooler, listed by Crompton at ₹21,500. That puts it above the ₹13,990 median for desert air coolers here.
On the specification: and it draws 200 W, which is roughly ₹2,880 across a 180-day season at ₹8 a unit. The honeycomb media is the right choice for hard water and is simple to rinse out.
Every figure here is Crompton's own published specification, read from www.crompton.co.in on 18 September 2026. We have not run this cooler; the score is calculated from those specs by the method printed on the air-cooler hub. Check the Amazon and Flipkart links before buying — street prices in a sale week are often below the brand store's own.
Manufacturer's stated features
- Honeycomb pads: better cooling per litre of water than wood wool, and far easier to rinse
- Draws 200 W — roughly ₹2,880 a season at ₹8/unit, a fraction of an air conditioner
- Separate ice chamber for a short boost on the hottest afternoons
Worth noting
- Evaporative cooling: performance falls away once relative humidity passes about 60%, so it suits dry heat far better than coastal or monsoon air
- Crompton does not publish an air delivery or air throw figure for this model, so cooling reach cannot be compared directly
- Needs an open window or door — in a sealed room it raises humidity until cooling stops
- No remote at this price
- Pads and the water tank need rinsing through the season, or airflow drops and the unit starts to smell
