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 Super Vac VR3 is a variable speed, electric, positive pressure fan evolved from the popular VR2 model. The VR3 is the only variable speed fan in the industry that will run on any 15 amp GFCI ...

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.

What is a variable frequency drive? Heating, ventilation, and air conditioning systems' air supply used to be constant volume into a space. Now a variable air volume control is being used to provide ...

Contrary to popular belief, fan speed settings aren’t always correct from the factory. It’s been a long-standing assumption that you should use the high-speed tap for cooling and low-speed tap for ...

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 ...

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.

Embraco has launched a new line of compressors with digital capacity modulation technology as well as its second generation of the Sync it All portfolio of integrated electronic components.
