SGL HVAC Engineers and Consultants: EC Fan

EC Fan

The current HVAC System deploys AC Asynchronous motors. That makes the current HVAC Systems in India consume more energy because of the power losses. In comparison, the BLDC motors or EC motors provide higher energy efficiency because of negligible power losses.



Depending on the application, the use of BLDC motors can result in savings of 15-50% on the energy front, thereby, reducing yearly electricity bills substantially.


Features of the BLDC Technology:

  1. 15-50% savings on the energy front based on the application
  2. Low acoustic noise
  3. Reduces the Operating Expenditure (OpEx) for an HVAC System because of energy savings
  4. EC Fan technologies (BLDC Technology) can be deployed for AHUs/CSUs, Condensor Fans, Evaporator Fans, Q Motors in Display Freezers/Multideck/Cold stores
  5. Based on the load requirement, the speed is varied.
  6. Direct drive motors for maintenance-free operation


With an EC fan (BLDC Fan), less power input is required to achieve the same fan speed as the AC fan, hence the power saving potential.


SGL HVAC Engineers and Consultants partner with leading global OEM for EC fans (BLDC Fans) and allied technologies to deliver optimum solutions for Customers.


EC Fan technologies can be deployed for AHUs/CSUs, Condensor Fans, Evaporator Fans, Q Motors in Display Freezers/Multideck/Cold stores.


Retrofitting of Existing HVAC System is also provided to achieve higher energy-efficiency thereby reducing the Building Operating Expenditures. A building owner can get up to 30% Energy Saving by Retrofitting the Existing HVAC System.


At SGL HVAC Engineers and Consultants, we take great pride in reducing our client's energy bill. An HVAC system consumes nearly 40% of total energy in any given commercial building such as an office space, mall, hospital, hotel, etc. And when the monthly electricity bill runs in millions of Rupees, then, certainly it makes sense to reduce this electricity bill thereby reducing the building's operating expenditure. We retrofit the existing commercial buildings such as an office space, mall, hospital, hotel, etc. with EC fans, and that results in massive savings on the energy front.
