Pump solutions for cooling circuits in rail vehicles
Modern rail vehicles utilise high-performance electric motors and power electronics systems, which are controlled via inverters. The conversion and control of electrical energy generates heat, which must be reliably dissipated to ensure safe and efficient operation.
With increasing performance requirements in high-speed trains, regional trains, underground trains and trams, liquid-cooled systems are becoming increasingly important. Water-glycol mixtures enable efficient cooling even where installation space is limited and power densities are high. HERMETIC canned motor pumps support operators and manufacturers with hermetically sealed, compact and low-maintenance solutions for closed cooling circuits.
Typical areas of application
Cooling of inverters and transistors in the locomotive
Media in action
