VFD solutions for heating, ventilation, air conditioning

HVAC is responsible for more than 30% of all electricity consumed in industrial and commercial sectors, with the motors that drive compressors, pumps and fans accounting for more than 98% of that energy. Variable Speed Drives when applied to these motors can provide energy savings of up to 60% while also enhancing system operation and comfort.

As a global company, we are well placed to help building owners, consultants, contractors and OEMs to maximize equipment efficiency and to keep pace with legislation and technology.
