Retro-Line ®

The Retro-Line self-regulating heating cable system is supplied in a predetermined length with all necessary components for a complete job-ready system. 

Retro-Line is a safe and reliable solution to internally freeze protect many different fluid pipe applications. 

This includes but is not limited to: residential water supply from wells, lakes, rivers, building to building and sump pump discharge lines and pressurized or high-volume water drain pipes which may consist of either metal and non-metal piping material. 

For polyethylene pipe applications Retro-Line is supplied with a compression style fitting for easy connection to the pipe. 

Retro-Line can also be ordered with a threaded male adapter to allow simple interfacing of the pipe heater wire with other pipe types and sizes such as ABS, PVC, PEX, copper, galvanized and steel.

The Retro-Line in-pipe heating cable system can be installed as a system for continuous water line freeze protection or as a precautionary system to use only if pipe frost protection is needed for a freeze-up. 

Even in applications where the pipes are intended to be dry for short or extended periods of time such as sump pump lines, the Retro-Line presents no danger of overheating or melting the pipe. 

This makes the Retro-Line an efficient pipe warmer, and suitable for all pipes, even plastic which does not always contain liquids. 

Retro-Line is a self-regulating pipe warmer that can be trusted to provide efficient and reliable freeze protection.

The Retro-Line in pipe heating cable system is constructed using high quality, industrial-grade trace heating cable which is robust and flexible, making installations easy, even in long length applications. 

Traditional or standard water line heat tape, water line heat wrap, heat trace tape, and pipe heat wire systems do not offer this level of installation capability. 

Short Retro-Line pipe frost protection systems can simply be pushed into the pipe while longer systems may need to be pulled in using a fish tape, string, or small rope. 

Retro-Line systems 40 ft. (12m) and longer are supplied on a dispensing reel to protect the heating cable and fittings from mechanical injury while the product is simply deployed into the pipe. 

It is not uncommon to push systems up to 150 ft. (46m). Another advantage of the pipe heater wire durability is the downward end of the cable does not need to be fastened as it will never move or slide up the pipe with the flow of the water. 

This feature is extremely important as it renders the heat trace cable fully serviceable. 

The system can easily be removed and replaced should it ever become necessary.

In most installations, and unlike standard water line heat wrap, all of the installation work can be performed at the entry point of the pipe without needing to access the far end.

Unlike traditional water line heat wrap or pipe heat trace tape, the Retro-Line self-regulating heating cable system includes the most advanced end seal technology making it the most reliable internal trace heating cable on the market. 

Retro-Line is suitable to be installed inside potable water supply systems which have water pressure of 230 PSI or less. 

For higher pressure systems see CARAPACE, RETRO-FM or contact Heat-Line and speak with an application specialist about our superior pipe heat tape and water line heat tape alternatives.

Retro-Line employs the unique and advanced performance of self-regulating heating cable technology. 

Unlike conventional water line heat wrap or pipe heat trace tape the Retro-Line system can effectively increase heat and energy output to every point microscopically along its length which is cold and simultaneously reduce heat and energy output to points that are warm. 

You never have to worry about the Retro-Line pipe heating cable overheating causing a risk of melting and fire because of the self-regulating pipe heating cable technology. 

Retro-Line gives you the peace of mind of reliable freeze protection without the risk. 

Have confidence in your Retro-Line heating cable system and no longer worry that your traditional electric heat tape for pipes with a thermostat is unreliable. 

It has become an essential product for homeowners, engineers, and building maintenance professionals to provide safe and reliable freeze protection.

An important feature and certification of the Retro-Line pipe heating cable products, which is sometimes overlooked when investigating and purchasing an internal heating cable, is that the Retro-Line system is NSF/ ANSI 61 certified Drinking Water Safe. 

This means that the Retro-Line system complies with all the required health effects criteria set by NSF for plumbing heat tapes and products that are part of a potable water supply system. 

This certification and feature are unmatched by standard electric heat tape for pipes with thermostats, pipe heater wires, heat trace tapes, and plumbing heat tapes.

To further increase the energy efficiency of your Retro-Line water pipe freeze protection system, it is recommended to add thermal insulation and a thermostat. 

The additional thermal insulation works to reduce heat loss from the heated water pipes, and the thermostat allows you to duty cycle your Retro-Line system based on pipe temperature. 

Both accessories combined can increase energy efficiency by as much as 80%. Installing an electric heat tape for pipes with a thermostat is an effective and reliable solution in any application where plumbing heat tape may be required.
