► Winning the space race - Beating the heat

April 23rd, 2014

Temperature issues and space constraints fuel demand for new, wider range of REO-USA liquid cooled Variable Frequency Drive components.

Energy savings versus fixed-speed motor technology have enabled Variable Frequency Drives (VFD)* to make their mark across a broad spectrum of industries via fan, pump and other control applications. Today an estimated 30%-40% of newly installed AC motors utilize VFD.

Nevertheless, design engineers face heightened challenges ranging from cost pressures and space limitations, to product reliability and longevity issues. The solution for many lies in bypassing traditional air-cooled drives for newer technology - liquid cooled VFDs - which, over the past several years have been emerging as the Next Big Thing.

"We're seeing a strong trend toward liquid-cooled VFDs for hybrid vehicles, HVAC, rail and marine applications, renewable energy, petro-chemical, food processing and more," reports Barbara Miller, Vice President of North American Operations for Indianapolis based component manufacturer REO-USA. She cites two key advantages:

- Liquid cooled components can reduce drive space requirements up to 70% or more

- Liquid cooling drastically lowers component surface and/or housing temperatures

Comparsion air-cooled and liquid-cooled reactors
Tested under the same load, the air cooled brake resistor runs at temperatures 70% higher than a liquid cooled REO-USA version and three times hotter than a fully encapsulated component. Liquid cooled drive components can last up to 50% longer. more

► REO USA expands its testing capabilities

April 10th, 2014

REO USA expands its acceptance testing capabilities with the acquisition of ed-k Power Choke Tester.

This unit allows for testing of inductance at currents up to 1500 A with a maximum energy pulse of 2500 J. Performance of this test ensures that inductive components produced at REO-USA maintain specified inductance values at currents far exceeding nominal requirements.
