3KW Tube Copper Water Cooled Wirewound Resistors With Mounting Bracket
Structure
1.ZENITHSUN is the first professional manufacture producing the water cooled resistor, many types are available, ceramic tube series, brass copper tube series and aluminum box series. The water cooled resistor box or cabinet are available ( according to the power rating).
2.The resistor applied high quality special resistor material, the resistor cavity is from by the special frame which provides the room making the purity industrial water flow through it, the water taking away the working heat.
3.The connector for in and out of water, for non-standard technical size requirements and custom special installation, please contact us to discuss the details.
4.For non-standard technical requirements and custom special applications, please contact us to discuss the details.
5.The Copper Tube Water Cooled Resistors is made of high-quality Red Copper as the matrix,unique insulating material and high-precision alloy wire wound. The unique welding method welding + 100% water pressure sealing test of each resistance eliminates the hidden danger of water leakage. Its outlet water temperature is between 40 ℃ and 60 ℃. When in use, the cooling water shall be supplied first, and then the power shall be supplied after the water flow meets the requirements and fills the inner cavity of the resistor; During shutdown, cut off the power supply first and then the water to avoid dry burning and damage of the resistor.
6.Ideal electronic component to be assembled inside high-power load banks.
Features
1.ZENITHSUN water cooled resistor owning great electrical characteristics,solid structure,safety,easy installation,low temperature,high power, great insulation,stability and durable, ect.
2.As the ordinary tap water as cooling carrier, eliminating the traditional way of deionized water high cost.
3.For non-standard technical requirements and custom special applications, please contact us to discuss the details.
