SUPERFAN – FAN RE ‘INVENTED’

Image
Superfan’s patented original design has brought numerous innovations to a stagnant Indian ceiling fan industry. The following are a select few that shows why Superfan is ‘Fan reinvented’. BLDC Ceiling Fans Super Energy Efficient Ceiling Fan (35 W) Superfan broke the 35W barrier to enable an Indian ceiling fan to enter the  super energy-efficient  category of appliances. This novel design has been awarded two patents  (2873/CHE/2009 and 3505/CHE/2012). Sensor-less BLDC control One of the challenges in BLDC technology was to minimize the failures of hall sensors. Superfan introduced the first ceiling fan in India with no hall sensor for position sensing. This was accomplished by developing a robust back EMF sensing in the firmware. Active Power Factor Correction The SMPS (Switch Mode Power Supply) is integrated with Active Power Factor Correction (APC).[a] Superfan has a power factor of 0.99* while running at the top speed. At the lowest speed (step speed 1), its p

INDIA’S MOST ENERGY EFFICIENT CEILING FANS?

Image
BLDC technology in ceiling fans is the latest in India, which led to  Super Energy Efficient Ceiling Fans  [1]. There are at least 27 manufacturers of BLDC ceiling fans with lofty claims like most efficient energy-efficient ceiling fans in India/World, highest air delivery, least power consumption, etc. These claims are deceptive marketing and a few bad apples who employ these tactics in the industry create a bad name for the entire industry and the technology. This article brings out the fallacy and futility of these marketing claims and its ill effects on the public. Superfan As we are a part of the industry, it is only fair to put forth our marketing claims. ‘India’s first super energy efficient ceiling fan’  – Superfan is the first BLDC fan in India and founded in 2012 by Versa Drives Pvt. Ltd, Coimbatore. This claim of being India’s first super energy-efficient ceiling fans is easily verified as there is only one ‘first’.  ‘Award-winning model – Super X1‘ – Super X

HOW SUPER ENERGY EFFICIENT CEILING FANS DIFFER FROM REGULAR CEILING FANS?

Ceiling fans are still the primary space cooling appliances in India. There are over 400 million ceiling fans in the country. They can be categorized based on their efficiency as: – Regular Ceiling fans – Energy Efficient ceiling fans –  Super energy efficient ceiling fans Regular Ceiling fans Regular fans are conventional ceiling fans built with an AC Induction Motor (ACIM). Typically, they consume around 75W and some old fans may consume up to 90W. The vast majority of ceiling fans under use are these ceiling fans. The large ceiling fan manufacturers are still promoting these inefficient choices due to its low manufacturing cost and their lack of motivation to develop alternative technology which benefits everybody. Disadvantage:  80-year-old technology, inefficiency, coil burning, unstable speed. Energy Efficient Ceiling Fans Energy efficient fans employ a minimum level of electronic technology to reduce power consumption. They are BEE (Bureau of Energy Efficienc

WHY SUPER ENERGY EFFICIENT CEILING FANS?

Regular old ceiling fans Ceiling fans escape one’s mind when thinking about reducing electricity cost. This forgotten appliance contributes significantly to electricity consumption due to its numbers and hours of usage. The following estimation supports this claim. A regular ceiling fan (1200 mm span) consumes about 75 W at the highest speed.  There are over 400 million regular ceiling fans in India and each of them creates an electricity demand about 39W* (consumption at medium speed). Super energy efficient ceiling fans At present Brushless Direct Current (BLDC) ceiling fan is the popular choice of  super energy efficient ceiling fans  in India. There are two premier BLDC ceiling fan brands in India –  Superfan  (Versa Drives Private Limited) and Gorilla fans (Atomberg Technologies)**. These ceiling fans (1200mm span) consume 35W at the highest speed so they save over 50% of electricity consumption. The higher efficiency comes with no compromise in ai

Image
The era of banner art South Indian Cinema was blooming in the 60s, 70s, and 80s; emanating art professionals and related small businesses. One such professional is Banner Artists. In this period banner art studios were the preferred avenue to create advertisements in public spaces. Hand painted large banners of size 100 sq. ft. were the advertisements for shops, movies, and politicians. During festivals, new movie release or elections, artists work consecutively for days with 15 to 20 assistants to finish banners or 30-foot-long cut-outs. They painted every known celebrity of their time. Their work was done mostly outdoors gratifying public and experimenting with dark colors to paint a hero like Rajinikanth or Vijayakanth or simple colors like shades of pink for the heroines. These artists don’t just copy the images, instead, reveal individual perspective on their art. Uniqueness was found in every stroke of the brush. Even though hundreds of posters and banners were painted
