Resistor liquid cooling boosts 3.3kV medium voltage loads, and slashes resistor footprint in industrial and marine applications, as David Atkins, projects director at Cressall Resistors explains
In motor driven applications like cranes, lifts, hoists and conveyors, air cooled resistors are common, but in medium voltage, high power applications liquid cooling wins out.
A medium voltage drive running off a 3.3kV supply to turn a 500kW motor will put a severe heating load on the application’s power transistors – hence the need for water cooling.
The new EV2 advanced water cooled modular resistor range for low and medium voltage applications is especially designed to function in severe environments, like the ones marine systems have to function in.
This patented design encapsulates and completely separates the resistor elements from the coolant. [Read more…] about Rough seas: Resistors for severe environments
