Key Features of Crompton Optimus 100 Litres Desert Air Cooler
100L Large Water Tank
The biggest highlight of this cooler is its 100-litre water tank. This large capacity helps the cooler run for long hours without frequent refilling. It is useful for families, shops, offices, and homes where the cooler needs to run for most of the day.
5500 CMH Air Delivery
The cooler offers 5500 CMH air delivery, which makes it suitable for larger rooms. Strong air delivery helps spread cool air across a wider area and gives better comfort during peak summer.
Suitable for Up to 650 Sq. Ft. Area
According to the product details, this cooler is suitable for spaces up to 650 sq. ft. This makes it a strong option for large bedrooms, living rooms, halls, and commercial spaces.
High-Density Honeycomb Cooling Pads
The Crompton Optimus 100L uses high-density honeycomb pads. These pads help hold water properly and improve cooling efficiency. Honeycomb pads are also more durable than basic grass-type pads.
Ice Chamber for Extra Cooling
The cooler comes with a large ice chamber. During very hot days, you can add ice for a stronger cooling effect. This is helpful when the room temperature is very high.
Auto-Fill and Drain Function
The auto-fill feature allows continuous water supply, while the auto-drain function helps in easy cleaning. These features make daily usage more convenient.
Humidity Control
The humidity control feature helps manage moisture levels. This is useful because desert coolers can sometimes increase humidity if used in closed rooms.
Inverter Compatible
The cooler uses around 200W power and is inverter compatible. This means you can continue using it during power cuts if your inverter supports the load.
Customer Review Insights
Based on current Amazon review signals, the Crompton Optimus 100L Desert Air Cooler has a rating of around 3.7 out of 5 stars from thousands of customer ratings.
Many customers like its large tank capacity, strong airflow, cooling performance, and body design. Some users also said that the cooler gives good value for money and works well for big rooms.
However, feedback is mixed in some areas. A few users have reported concerns related to value for money, water leakage, service experience, and delivery condition. So, after delivery, it is important to check the cooler properly, including wheels, tank, pump, and water flow.
Cooling Performance
The cooling performance of this cooler is strong when used correctly. Since it is a desert cooler, it performs best in dry weather and with proper cross-ventilation.
For best results:
- Keep a window or door slightly open
- Do not use it in a fully closed room
- Fill the tank properly
- Clean the cooling pads regularly
- Use ice chamber only when extra cooling is needed
- Place the cooler where it can pull fresh outside air
If used in a closed or humid room, cooling performance may reduce.
Build Quality and Design
The Crompton Optimus 100L has a tall and practical desert cooler design. It comes in white color and has a plastic body. The large tank and wide body make it suitable for serious summer cooling, but it also means it needs more floor space than small coolers.
It comes with castor wheels, which help in movement, but due to its large size and water capacity, moving it when full may not be very easy.
Noise Level
As this is a large desert cooler with powerful airflow, some fan noise is expected, especially at high speed. For daytime use, the sound should be manageable for most users. But if you are very sensitive to noise while sleeping, you may prefer using it on low or medium speed at night.
