Atomberg Renesa Enzel 1200mm BLDC Fan Review: Frugal and Quiet

The Atomberg Renesa Enzel is for anyone who runs a fan most of the day and wants low electricity use and near-silence in the bedroom. The trade-off is that you give up the repair-anywhere simplicity of an induction fan: when the electronics fail, you wait for an Atomberg technician rather than walking to a local shop.

How much electricity does the Atomberg Renesa Enzel save?

At top speed it drew 29 W, against 75 W for a typical induction fan of the same sweep. At 12 hours a day and a tariff of ₹8 per unit, that is a saving of about ₹1,612 a year per fan. On the middle speed setting the fan drew roughly 15 W, so a bedroom fan used mostly on speed 3 saves more than the top-speed figure suggests. Add three or four fans in a flat and the annual difference becomes noticeable on the bill.

Does it throw enough air in peak summer?

Air speed at 1.5 m below the blades was 2.4 m/s at top speed, the best in this group, and a little higher than the Crompton and Havells. Boost mode raises the speed for a few minutes and then returns to your setting, which is useful when you come in from the heat. In a 12 by 12 ft bedroom it kept the bed area comfortable on the third speed on hot nights.

Will it run on an inverter?

This is where a 28 W motor pays off. On a 900 VA inverter with a 150 Ah battery and two 9 W LED bulbs, the fan at top speed ran for about 21 hours before the inverter cut off. At speed 2 the same setup lasted well past a full night. Compared with an induction fan, the same battery gives you more than twice the fan hours.

How quiet is the Atomberg Renesa Enzel?

We measured about 47 dB at one metre at top speed, and below 40 dB on the lowest speeds, where you mainly hear air rather than the motor. Bearings were silent at the start and after six weeks. There was no wobble with the blades set correctly, so make sure your electrician tightens all three screws evenly.

What happens at low voltage?

We stepped the supply from 250 V down to 180 V. The fan kept its speed with only a slight drop below about 190 V and never stalled or restarted. Listings state a 165 to 285 V operating range, and our test agrees at the lower end. A stabiliser is not needed.

What do owners complain about?

Retailer reviews for Atomberg fans most often mention remote problems and the wait for service visits in smaller towns, while praising the quiet and the power bill. We saw the remote lose pairing once after a power cut and re-pair it by holding the button on the remote. Dust gathers on the blades quickly in a monsoon-damp room, so wipe them monthly.

Is installation difficult?

Any electrician can hang it on the standard down-rod, and the supplied rod suits ceilings up to about 10 feet. For higher ceilings, buy a longer rod from the dealer, since the fan runs best 8 to 9 feet above the floor. No regulator or wiring change is needed.

Who should buy something else?

Buyers who want a decorative fan with a wooden finish should look at the Havells. Those who want the lowest sticker price should compare the Superfan or the Crompton, which also carry BEE 5 star ratings.
