Product Description

Product Description

The cable is a Self-regulating / Self-limiting heating cable, often described as heat trace cable or heating tape, however this cable automatically adjusts heat output as needed, based on surface temperature. Ideal for freeze protection and low temperature process maintenance such as your RV's fresh water supply tubing in need of heat protection, the smaller volume of fluids within these lines are normally the first to freeze up and restrict flow in cold weather.

This cable is a great remedy for those longer runs that are exposed to the cold, the heat cable length can customized, please contact us and the length can be easily shortened in the field to fit if needed, or you can use multiple cables wired in parallel for those longer lengths. Works great on either Pex style or Vinyl reinforced fresh water supply lines.  Just securely zip-tie the cable along the length of the tubing ensuring the entire length of tubing along with all fittings and connectors are in direct contact with the cable to prevent freezing.  If you elect to take it a step further, wrapping the tubing in foil (sold separately) and/or insulating the tubing and cable with something like pipe wrap insulation will allow operation in even lower temperatures. 
And of course, the cable can be used for other heating applications with low voltage DC power supply.

Self-regulating Working Principle:

Structure:
1. Copper conductor

2. Conductive heating element

3. PE outer sheath

Product advantages

1. Equal temperature safe and reliable.

2. Save electric energy.

3. Rapidly Temperature increase

4. Low cost of installation and operation

5. Easy to install and maintain.

6. Convenient for automatic management.

7. No pollute environment.

8.Easy install, connect the cold wire directly to the 12v power supply to use!

Installation Instructions

Notice:This 12v heating cable can only be connected to 12v power supply, otherwise it will be damaged.

1. Wrap the heating cable on water pipes or fastening straight on pipes, both are ok.

Put the whole cable on the pipes and fasten it every 30~60cm with thermal tape or aluminum tape.

2. Suggest to wrap a layer of rubber insulation on the pipe, enhance efficiency of the heating cable and save energy, also can protect the heating cables.
