Detailed Product Description

2KW High Power Aluminum Housed Water Cooled Wirewound Resistors

 

Structure

1.High Power,Small Size,Water Circulation cooling with low temperature,replacement the high cost traditional deionized wate;
2.The aluminum housed water-cooled resistor 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 eliminates the hidden danger of water leakage.Its outlet water temperature is between 40 ℃ and 60 ℃, the cooling water shall be supplied first when in use,and then the power shall be supplied after the water flow meets the requirements and fills the inner cavity of the resistor;
3.During shutdown, cut off the power supply first and then the water ,to avoid dry burning and damage of the resistor.
4.Flying leads/Termianls leading out .
5.For non-standard technical requirements and custom special applications,please contact us to discuss the details.

 

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.Water cooled resistors circularly cooled by flowing tap water (or distilled water or other liquid),replacement the high cost traditional deionized water.
