Variable Frequency Drives
One of the most successful energy management tools ever applied to building HVAC systems is the variable frequency drive (VFD). A Variable Frequency Drive (VFD) is a type of adjustable-speed drive used in electro-mechanical drive systems to control AC motor speed and torque by varying motor input frequency and voltage. Over the last four decades, VFDs have successfully been installed on fan and pump motors in a range of variable load applications. As technology has advanced, VFD cost and size has reduced and performance has improved through advances in semiconductor switching devices, drive topologies, simulation and control techniques, and control hardware and software.
So why should you install a VFD in your facility?
SmartVFD HVAC2 standalone variable frequency drives (VFD) are designed to control HVAC motors and pumps up to 25HP to maximize energy efficiency. SmartVFD HVAC2 is a small footprint drive that can fit in your existing enclosure or become a NEMA 1 enclosure. SmartVFD HVAC2 drives can be mounted side by side with the proper free space for cooling airflow circulation.
SmartVFD HVAC is a standalone variable frequency drive (VFD) designed for use in HVAC applications to control the speed of HVAC pumps and fans in order to maximize energy efficiency. Smart VFD is also designed to run three-phase standard and high efficiency induction motors by varying the output voltage and frequency.
SmartVFD COMPACT Drives
SmartVFD COMPACT is among the smallest, most streamlined energy saving variable frequency drives (VFD) available. An intuitive user interface lets you customize drive features to the application, eliminating waste and optimizing energy efficiency in HVAC pumps and fans. A free PC Tool with an optional adaptor turns your computer into a programming window to setup, control, monitor and diagnose in real time or for off-line editing and backup.
