Self regulating Heating Cable
The low-temperature controlled heating cable (self-regulating heating belt) developed by Ruihua wonderful used in fire protection, petroleum, chemical industry, iron and steel, electric power and so on to keep pipes, tanks warm and prevent frostbite. This cable is suitable for ordinary areas,hazardous areas and corrosive areas, etc..Product type: DWK (BTV、DXW、DKW、ZKWD、DBW、ZDL), relative to BTVR series of RoychemTemperature
Electrical trace-heating for frost prodection
Water lines and process pipework can become a real problem when temperatures drop below freezing. It’s only when the thaw comes that you realise the damage a split or cracked water pipe can cause.
The (XEL) family of self-regulating,parallel circuit heating cables is used for frost protection of metal and plastic pipes and vessels.With the facility to cut on site to the problem of frozen pipework.
It can also be used for low temperature process maintenance up to 30 ℃。Maximum exposure temperature 90℃.
Will not withstand steam cleaning process.
For safe or hazardous area applications.
