Crompton Ozone vs Optimus – What’s the same?

Type & Build

Both air coolers are made by Crompton, a well-known brand in India that produces various kinds of home devices. They are made of ABS plastic which is strong enough to withstand water pressure and will not rust over the years. Plus, the overload protection of both desert coolers saves you from high voltages and ensures maximum comfort at home.

Cooling Medium

Both the Ozone and Optimus come with large honeycomb pads covering all three sides of the desert air cooler. They are very good at retaining water to turn the hot outside air into water-cooled vapour very quickly. Plus, they can effectively cover a large area to never miss a spot.

Pump & Ice chamber

Everlast pumps of the same performance are installed in both air coolers. The pump can automatically fill water in no time and you only need to press a button when the device is empty. You also get an ice chamber in both coolers to make the air flowing suitable for any summer day.

Crompton Ozone vs Optimus – What’s so different?


When comparing the design of the Crompton Ozone with the Optimus, we found a big difference between the two. The Ozone comes in a white body with teal accents, while the Optimus air cooler comes in a white and black colour combination. Also, the Optimus is much more portable in size but has a heavier frame, and the small wheels make it easier to switch rooms at any time.

Capacity & Controls

For starters, you get a capacity of 75 litres on first, while the second cooler has a capacity of 65 litres. Both devices also come with a knob you can turn to change any setting, but the first air cooler has two and the second one has three to give users more control.

Speed & Coverage

The Optimus Desert Air Cooler is available at higher speeds and ranges due to the larger motor and fan size. On average, with Optimus you can cover up to 650 sq. ft. at 5500 m3/hrs., whereas Ozone at 4200 m3/hrs. covers only 490 sq. ft.

Mosquito Net

Only the Optimus desert cooler has a mosquito net between the two. It helps keep mosquitoes out of the water and prevents them from laying eggs in the tank. Other impurities also get filtered from nets and the water pump life increases over the years.


Power consumption is an important factor that people in India consider and there is little difference between the two air coolers. Ozone and Optimus use the same input voltage to run at full speed but the consumption remains different. With a bigger motor, the Optimus produces more power, at 200 watts while the Ozone takes 190 watts at maximum to help save energy in the long term.

Water Inlet & Auto Drain

To help you fill water from any home faucet, both desert air coolers are equipped with large inlets, but their locations do not match. The first device gives you a water inlet on the front, while the second option gives you a reverse entrance. Plus, the automatic drain feature is only available with the Optimus air cooler, making your life easier by clearing out the water when it gets dirty.
