When Kai is on a business trip, Eta always accompanies him

For meetings, site visits or a service job, travelling for business can be exhausting. Often, the agenda is large and time is at a premium. It’s great that you can reliably reach many places in a relaxed way, using the train.

This is where Eta comes in: Whenever you board a train, chances are that Etaseco RVP keeps the power electronics going…

Power electronics cooled by Etaseco RVP

In high-speed trains, high-performance locomotives and suburban trains worldwide, the Etaseco RVP type series plays a leading role: When the single-phase alternating current from overhead power lines is converted into three-phase alternating current for the motors driving the train, a lot of heat has to be dissipated. This is where the canned motor pump comes in: In the cooling circuit it continuously recirculates the coolant, a glycol/water mixture, thus protecting the high-performance motors from overheating.
Cooling the inverters is not all: Etaseco RVP can also be used for cooling batteries and fuel cells, and for pre-heating and cooling the motors.

By the way: The canned motor pumps of the Etaseco type series in their non-ATEX compliant version, available for a larger power range, are also suitable as coolant pumps in other industrial applications and in wind power systems.
