High energy consumption and different temperature areas lead to retrofitting
   
Before Ubisoft had a chilled water HVAC system, the office temperature was controlled by Dampers in air ducts in their premises in Pune. At that time the AHU* motors were connected to BMS system and were running at full speed. That resulted in high consumption of energy; it also generated hot and cold areas in the office. To get better control and to save energy they therefore decided to install VFDs on AHU.

Speed controlled by VFDs

CG Drives & Automation recommended the VFD solution on AHU motors connected to BMS system. The VFD controls the speed of motor based on 4-20mA signals. CG Drives & Automation has supplied 4 pcs of 15KW VFDs.

Clear Energy Savings

Controlling the AHU system with VFD and avoiding the damping system has clearly given energy savings up to 20-25 %. The investment was recovered in less than 12 months and the savings that was directly added to company`s profits.

After completing almost a year of commission, Ubisoft was very pleased with the performance of CG Drives & Automations VFDs and the service support provided as, and when required. Ubisoft has appreciated the performance of CG Drives & Automations drives and kindly documented it with an appreciation letter. (Below)
