Series Constant Wattage Heating Cable, RDC
Shenzhuan RDC series constant wattage heating cable is generally used where temperatures up to 250℃ is to be maintained for a long period of time. As a constant power cable, the heat tracing cable is a succession of identical resistors, making it possible to have the same power dissipation on each of these sections. In this way, it can ensure precise and constant temperature output regardless of ambient and surface temperatures, which is exactly different from other parallel constant heating tracing cables. With process temperature maintenance and freeze protection, this flexible heating cable is well applicable in petrochemical plants, chemical industry, building and construction sector and other industries for frost protection, insulation and heat tracing of long gas or oil pipelines, pipes, tanks, pumps, etc .
- Freeze protection
- Condensation prevention
- Process control
- Viscosity control
- Composite curing
