Brand that doesn’t compromises with air: Atomberg Renesa Smart+ and Atomberg Studio + Ceiling Fans Review

A Mumbai Based startup that delivered the promise of giving air in the every corner of your room. Atomberg technologies is working hard on its R&D to give the best in Indian market. It is one of the most popular BLDC fan brand with 10 Million+ fan customers. It has revolutionized the ceiling fan industry with its pathbreaking technology. Atomberg fans have stood out from a considerable chunk in the lifestyle fan category and Atomberg is elevating innovation in terms of introducing a slew of lifestyle-oriented products.


Ceiling fans are one of the most ignored appliance when it comes to energy savings. People talk about big appliances like AC and refrigerator consuming lot of energy. After the big appliances focus shifts to small to medium appliances like washing machines, microwave ovens, mixer grinders etc. Even tube lights are something where people find scope for saving energy. To save energy on big appliances like AC, refrigerator, washing machines etc. manufacturers are rapidly adopting inverter-based circuitry inside to reduce energy consumption.

There was a looming need for innovation in ceiling fans for some time now specially to mitigate its energy consumption. That’s where Atomberg has hit the right chord by offering highly energy efficient fans using BLDC (Brush-less direct current) motor. Atomberg Technologies was started by talented graduates from IIT Bombay in 2012. This modern hardware company was started with an aim to eradicate the gap between energy efficient appliance and the air delivery rate, without compromising on the functionality. Thanks to the aerodynamic profile of its blades coupled with its hydrophobic, high gloss PU finish, the fan makes very less noise compared to high-end fans from any other brand in the market.


Atomberg innovation brought 5 star BEE rated fans at affordable prices to Indian household. 5 Star BEE rated fans can help consumers to recover fan cost in 1-2 years of its usage easily. Atomberg fans saves almost 65% of energy when we compare them with other brands ceiling fans.


This time, we are going to talk about Atomberg Renesa Smart+ Ceiling Fan and Atomberg Studio +, which also happens to be the first of its kind in many aspects (which we’ll cover below). When something like this is invented, it would be an injustice to not do a detailed breakdown of the incredible engineering acumen of this new innovative product. We’ll say majority of the hardware of both fans are similar, only Renesa Smart+ is IOT enabled and can be controlled via mobile app, Alexa and other voice assistants that’s why it is having an edge over others models.

Key Technologies and Features 


BLDC Technology

BLDC technology, in general, has been in the market for a couple of decades and it is widely implemented in industries needing high torque motors. What was missing so long is its application in the ceiling fans. They are the pioneers of using BLDC motor in the ceiling fans in India. The traditional fan uses an induction motor and typically consumes 70-90 watts. But BLDC fan, on the other hand, can reduce power consumption up to 65%

A BLDC fan, on the other hand, works on direct current (DC) instead of alternating current (AC).  This is done by internally converting the AC voltage to DC voltage using switch mode power supply (SMPS).


Advantages of BLDC Motor Used in BLDC Fan

Prominent technical advantages of BLDC motor over induction motor is summarized as:

·      Lower electricity consumption (65% savings)

·      Longer backup on Inverters (works even on solar power)

·      Improved reliability

·      Noise reduction

·      Longer lifetime


Remote Control with Timer and Sleep Modes

One of the main USP (unique selling prospect) of BLDC fans is they can be controlled wirelessly like a TV or an AC. This is a boon for someone who finds it onerous to get up from a place towards the side where regulator is installed to change the speed of the fan. Fans come with an infrared remote with many good features like speed control, timer and sleep mode. On the remote you will find 5-speed settings wherein you can press number between 1 to 5 to adjust speed with 1 being the lowest speed setting. 


Additionally, there is boost button which can provide an additional thrust for a better airflow. In short, you can consider it to ‘6th‘ speed setting. The timer button allows you to run fan for specific hours. You can set the timer to 1 hour, 2 hour, 3 hour or 6 hour. Remote also features sleep mode, which is useful for a good night sleep. Upon activation, it first sets the speed to an optimum level (usually at higher RPM) but as the time progresses it gradually decreases the speed. This it does to match the falling night temperature. It is observed that as the night progresses temperature dips a little. So this way it smartly reduces the speed in sync with the ambient temperature giving you the dual benefits–comfort plus energy savings. 


No Eddy Current and Heat Losses

Conventional ceiling fans work on alternating current (AC) as they used induction motors. As a result they are prone to Eddy current losses. So, what are Eddy current losses? Well, the magnetic field surrounding a coil carrying AC current varies with time and thus induces voltages in nearby conductive material inside the ceiling fan circuitry. The resulting currents are called Eddy currents. They are called ‘Eddy’ because they flow in circular patterns like eddies in a brook. Eddy current are unwanted and create power losses. Technically, they are called Eddy current losses. 


They are undesirable because it increases the power consumption of the fan and also lead to generation of heat. This in turn increases wear and tear of the induction motor inside a conventional ceiling fan. But as the fans from Atomberg uses BLDC motor which works on direct current (DC) there is no chance of Eddy current losses. You’ll notice that BLDC fans do not get heated as much as their induction-based ceiling fan counterpart (provided they are of same size and run at the same RPM).


Regulator-less Operation

To control the speed of ordinary fans you need to install a regulator compulsorily. But that’s not the case with Atomberg BLDC fans. They do not come with a need to install a separate regulator which saves cost. And in case you decide to replace your old ceiling fan with BLDC fan you can still keep the regulator in its place. But make sure you set it to maximum level and then control the remaining functions of the fan with the wireless remote which comes with the BLDC fan.


Pros and Cons

Energy saving is the biggest selling point for Atomberg fans. Thanks to its new BLDC technology their fans even at a peak speed consumes just 28 watts of energy. This is way less than ordinary ceiling fans consuming over 75 watts of energy. Atomberg has used good quality of materials in construction of the fan. As opposed to sheet metal used in ordinary BEE 5-star rated fans, Fans uses high quality aluminium in fan blades and comes with rust-resistant property. Aluminium material used is lighter and therefore ensures a better airflow. Fans were tested in the prestigious IIT laboratories for its quality and they are capable of working even in fluctuating voltages. They can work in the voltage ranging from 110V to 285V.




We will rate both products as a stealer deal, we’ll rate Atomberg Renesa Smart+ as 9/10 and Atomberg Studio + Ceiling fan as 8.7/10. Atomberg Studio + Ceiling fan is premium looking product with a highlighting design on fans whereas Atomberg Renesa Smart+ is IOT enabled product and can be monitored/ controlled by smartphone and voice commands. You can visit Atomberg Website and get special discounts as well.  If all fans in India were replaced by BLDC fans (which Atomberg specializes in), five crore Indians would gain access to electricity, at existing power generation levels. That speaks volume about the potential of BLDC fans and its share to improve the condition power-deficit Indian market. Moreover, BLDC fans would be way forward in future as the company Atomberg is working on adding more smart features to its fans and making it the part of IoT. Even big organizations like the IITs, the TATAs, the Birlas have realized the value of having BLDC fans over induction-based fans. They have widely adopted BLDC fans in their offices and rooms. This adoption is not only for energy savings but also for the smart functions like sleep and timer they bring. And this goes without saying that fans can conveniently controlled through wireless remote. So, we strongly recommend Atomberg’s BLDC fans if you are a heavy fan user and yearn for the convenience of using remote to control your fan.
