Understand the characteristics of water-cooled resistors
2025-06-19
The water-cooled resistor is a resistor that is cooled by forced circulation of regular tap water. The inlet water temperature ranges from -40℃ to 60℃. When installing the resistor, it is required that the inlet end faces downward and the outlet end faces upward. During use, the cooling water should be turned on first, and then the power should be turned on after the water flow reaches the required level and fills the inner cavity of the resistor. When not in use, the power should be cut off first, followed by the water supply to avoid the resistor body from being burned out and damaged. When it is necessary to use water sources again, we will add a water cooling circulation system according to the requirements.
The water-cooled resistor features no noise, high power, small size, stable operation, safety and reliability, low temperature rise, and no requirements for environment or temperature.
Water-cooled resistors are used for braking or load applications. As a result, water-cooled resistors are gradually replacing the air-cooling method more and more. Various scientific research projects, ships, exercise equipment, oil drilling rigs, lifting vessels, high-power power supplies, new energy sources, electric locomotives, high-voltage frequency converters, as well as various types of ships and various power systems are gradually replacing traditional air-cooling resistors with water-cooled resistors.
