Variable Frequency Drives
Efficiency, Speed and Power in your control. Who knew saving energy was this easy?
Fans, pumps, air handlers, and chillers all benefit from speed control. Did you know Variable Frequency Drives provide advantages in energy savings, low motor starting current, reduction of thermal and mechanical stresses on motors and belts during starts? This all equates to a smoother, longer lasting and more efficient operation process.
Variable Frequency Drives offer many benefits to your electric motors. VFDs offer greater control over the speed of AC motors, enabling the removal of throttling devices, valves and dampers, all of which can waste energy. By regulating speed, VFDs prolong the life and reduce the maintenance costs of motors, driven equipment and switch gears. VFDs also give users a finer degree of control, resulting in more precise process operations and improved product quality.
The most significant benefit to using a VFD is energy savings.
Variable Frequency Drives (VFD) allow motors responsible for moving air or liquids to run at varying speeds. Traditionally motors used to move air or fluid have either been in the off position or running at 100% power with no in between. Flow of air or liquid was controlled through other mechanical means of restriction.
Roughly 65% of AC motor applications are variable speed in nature and can provide significant energy avoidance with the installation of variable frequency drives which allow motor speed to be modulated to meet the demand of the application based on varying building loads. A motor operating at 50% speed results in an energy usage reduction of 88%.
ROI on a VFD installation can be in as little as six months.
