When you are looking for an efficient method for enclosure cooling, a heat exchanger is a good solution for a few different reasons. Not only is a heat exchanger energy efficient, but it allows you to maintain a completely closed loop enclosure cooling solution. The way a heat exchanger operates is by employing a heat pipe principle to exchange heat from an electrical enclosure to the outside. ...
With rising energy costs and shortages around the world, the Power and Process industries continue to seek innovative solutions. The demand for energy worldwide continues to rise faster than generating capacity, and the deregulation of the electric power industry has created a demand for products that will make power producers more efficient. ...

Read this free whitepaper to find out more about UPS capacitors Capacitors are an integral part in any UPS system, smoothing, filtering and storing energy. But they are also amongst the components in an uninterruptible power supply that are most likely to fail (along with batteries). ...
The Importance of Power Converter Efficiency Power converters such as transformers are widely recognized as one of the necessary components of an electrical distribution system. Similarly, inductors such as coil, choke and reactors used as filters in power supplies play a large role in storing and transferring energy in the ...
“Solar power is India’s opportunity of a lifetime. It has the power to address not only India’s development problems, but it could also be a game changer for global climate change,” says Tobias Engelmeier, director of Bridge to India. ...
