Part-load efficiency is rapidly becoming the most important measure of energy efficiency in chiller units. Around the world, new environmental standards are increasingly based on a combined part-load ...

A new variable-speed fan drive system with gearbox from Horton and Hub City provides more efficient cooling for rear-engine buses and motor coaches with side-mounted cooling modules, Horton has ...

The way we control the speed of fan motors or pump motors has tremendously changed in the past two decades with the introduction of variable-frequency drives (VFDs), aka variable-frequency controllers ...

N C Machinery is a venerated, Anchorage-based company. Its Power Systems Division supplies and services rental generator sets, primarily to Washington and Alaska. It maintains 18 support facilities in ...

Fans are often used to ventilate agricultural buildings. Adjoining rooms with connecting air paths through open doors or manure channels can operate as a single room with a common negative pressure.

Designed for high-pressure applications, Oneida Air’s Smart Boost dust collectors combine variable speed fan motors with the separation performance of a cyclone. Powered by brushless motors, the ...

Many power plants regulate fan airflow with mechanical controls, such as dampers. In some applications using fixed-speed motors in combination with dampers may not be the most energy efficient option.

When implementing cooling solutions for electronic equipment, system designers are confronted with a complex set of variables. The cooling requirements are typically dynamic, and ambient temperatures ...
