For many retrofit projects, the use of a VFD seems like a “no brainer.” Drives are now cheaper and more reliable than ever, and the benefits of efficient control of motors can’t be beat. Still, there ...

Variable frequency drives (VFDs), also known as variable speed drives (VSDs), are used to modulate the speed of motors in various applications, from hydronic water pumping to VAV fan units to vacuum ...

Tighter speed regulation (typically ±0.05%) is often the benefit of an encoder-based variable-speed drive, but costs more up front. Lower speed regulation (typically -3% to -5%), which is offered by ...

Horton has released a new two-speed fan drive for medium-duty trucks, buses, severe service vehicles, rear engine cement mixers and other on- and off-highway equipment with little to no ram air Horton ...

Compressed air is a vital utility to most commercial and industrial operations. It runs essential tools and machinery, provides power to material-handling systems, and clean air to processes. Yet ...

The GA800 variable speed drives handle applications ranging from simple fans and pumps to high-performance test dynamometers requiring precise regulation. They feature highly flexible network ...
