Product Details

40KW40R Water Cooled Resistor Banks For Emergency Stand-By Power Systems

 

Structure

1.High Power,small size,water circulation cooled,low temperature,eliminates the high cost of traditional deionized water.
2.It is circularly cooled by flowing tap water (or distilled water or other liquid),eliminates the high cost of traditional deionized water.
3.High power,small size,stable operation,high insulation,good sealing,low temperature and long service life.
4.Power Range:1kW - 5MW (others on request).
5.Multiple safety protection functions :short circuit,over-current,over-voltage,over-load,over temperature,fan fault,audible and visual alarm device, etc.
7.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.
4.The water-cooled unit can be installed indoors in a controlled environment versus an outdoor installation which is exposed to the elements.
5.The water-cooled Load Bank operates at much lower temperatures than an air-cooled unit.
