Variable-pitch drives are the simplest of all mechanical adjustable-speed mechanisms. Most of these drives use rubber belts. However, chain types are unmatched in regard to its particular strong ...

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 ...

Variable-speed pump drive technology that matches pressure supply to demand is creating the ability for energy-efficient hydraulics to produce energy savings in the range of 30 percent to 80 percent.

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 ...

In an industry evolving alongside consumer concerns over rising energy costs, impact on the environment, and, of course, stricter regulations handed down by the government, new technologies are ...
