20-40kW Water Cooled Resistor with Pin Fin Cooling & Ultra-Low Inductance Design
Looking for a high power resistor that combines compact size with exceptional performance? Our 20–40kW water cooled resistor is specifically designed to meet the demands of modern high-power applications while maintaining excellent thermal and electrical characteristics.
At the heart of this resistor is a serpentine wound resistive element engineered for ultra-low inductance, ensuring minimal voltage spikes and electromagnetic interference (EMI). This makes it especially suitable for use in high-speed switching circuits and regenerative braking systems.
The internal cooling system utilizes an innovative Pin Fin water channel design , which significantly increases the surface area for heat transfer, allowing for more effective and uniform cooling across the entire resistor body.
To further enhance durability and safety, all liquid-cooled components are joined using stir friction welding (SFW) — a cutting-edge process that creates hermetically sealed joints without the risk of leaks or degradation over time.
This combination of low inductance , efficient cooling , and leak-proof construction makes our water cooled resistor a top choice for:
EV battery testing systems
Industrial motor drives
Energy regeneration units
Power electronics laboratories
