Innovation just hit a new high. On December 19, 2025, Crompton Greaves Consumer Electricals Limited (CGCEL) secured a landmark patent. The Indian Patent Office granted patent number 576195 for a breakthrough in energy-efficient cooling. This technology does more than just blow air. It bridges the gap between your ceiling fan and your air conditioner.
This news comes at a perfect time. Only days ago, the President of India honored Crompton with the National Energy Conservation Award 2025. The company is on a winning streak. They are proving that sustainability and high-tech comfort can go hand in hand.
The Innovation: A “Deep Sleep” Revolution
For years, consumers faced a choice. They could freeze under an AC or stay warm with just a fan. Running an AC at 18°C wastes massive amounts of power. Running a fan alone often fails in the scorching Indian heat. Crompton’s new patented system solves this.
The technology uses a retrofit controller device. This device talks to both your fan and your AC. It uses an Infrared (IR) communication protocol to sync them. It doesn’t matter what brand of AC you own. The controller features a 360-degree IR reach and interoperable codes. It works with almost anything.
Key Features of the Patent:
- Environmental Intelligence: Sensors track temperature and humidity in real-time.
- The Deep Sleep Algorithm: This software adjusts fan speeds and AC settings automatically. It ensures uniform cooling across the entire room.
- OTA Updates: The system stays smart. It receives “Over-the-Air” updates to improve performance over time.
- Universal Compatibility: It controls ceiling fan status and speed either locally or wirelessly.
Power Words: Efficiency, Savings, and Comfort
Crompton is not just selling a gadget. They are selling a “Greener Future.” By using a fan to circulate AC air more effectively, users can set their ACs to a higher, more efficient temperature (like 26°C). This simple shift can slash electricity bills.
The company’s ActivBLDC motor technology already saves up to 50% on fan energy. Now, by optimizing the AC—the biggest energy hog in most homes—Crompton is targeting the heart of household expenses.
Market Impact: Crompton 2.0
This patent is a pillar of the “Crompton 2.0” strategy. Managed by CEO Promeet Ghosh, this vision focuses on premium products and consumer-centric innovation. The goal is clear: double the company’s turnover in the next five to six years.
Investors are watching closely. While the stock has seen volatility this year, analysts remain bullish. The patent reinforces Crompton’s moat against competitors. It transforms a standard fan manufacturer into a “Smart Climate” leader.
