The KF is Copeland’s variable-speed scroll compressor for the 1.5- to 5-ton North American residential market, designed for ...

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 ...

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 ...

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 ...

When powering AC motors, the electrical supply can be at full power to run at full speed or at variable power to run at variable speed. Applications with varying loads benefit from the variable speed ...

Imagine an easy-to-install industrial technology that reduces energy consumption, eliminates mechanical vibrations and electronic harmonics, relaxes alignment tolerances and cuts maintenance needs.

It is interesting to look at figures from the Energy Information Administration about where energy gets consumed in our economy. These figures reveal that industrial uses account for 31% of all energy ...

Variable speed drive (VSD) compressors are widely regarded as a more energy-efficient alternative to fixed-speed machines in applications with fluctuating demand. As industry looks for ways to cut ...

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 ...
