We specialize in EC Fan Retrofit Solutions for existing Air Handling Units (AHUs), where we replace the old belt and pulley-driven systems with high-efficiency EC fans or arrays of EC fans, depending on the required airflow (CFM) and static pressure. This retrofit approach transforms aging AHUs into modern, energy-efficient systems with optimized performance and minimal maintenance. Our retrofit projects range from single-fan replacements to large fan arrays. With more than 25,000 EC fans installed across industries such as automobiles, pharmaceuticals, FMCG, healthcare, hospitals, hospitality, malls, textiles, and comfort cooling, our solutions have consistently delivered 40–60% energy savings and drastically reduced operational costs.
An energy retrofit leads to substantial reductions in energy consumption compared to conventional systems, based on a detailed analysis of existing system parameters. In many cases, our retrofits achieve over 50% reduction in power consumption, depending on variable operating conditions. Beyond energy efficiency, EC fan retrofits eliminate the need for belts, pulleys, and related maintenance, providing higher reliability, quieter operation, and longer system life. With typical payback periods of around 2 years and EC fan lifespans exceeding 10 years, the savings far outweigh the investment, ensuring long-term financial and operational benefits.
By upgrading AHUs with plug fans using EC motor technology, organizations can realize significant reductions in OPEX, improved sustainability, and hassle-free maintenance.
An energy retrofit leads to substantially reduced energy consumption over conventional systems based on detailed analysis of existing system parameters. The resultant of our Aad Tech Retrofit Solutions is sometimes more than 50% reduction in power consumption dependent upon variable factors.
Energy efficiency has become an integral part of building services design, maintenance and upgrade. Many organisations overlook air handling units (AHU’s) when looking to save energy. Upgrading AHU’s with plug fans using EC motor technology can realise significant savings in energy, maintenance and more.
