Tandem-Link employs the unique and advanced performance of self-regulating heat trace cable. Constructed of self-regulating heat cable technology the Tandem-Link system can effectively increase heat and energy output to points microscopically along its length which are cold and simultaneously reduce heat and energy output to points which are warm. You never have to worry about the Tandem-Link heating cable overheating causing risk of melting and fire because of the self-regulating trace heating technology. Tandem-Link gives you the peace of mind knowing that you have reliable freeze protection without the risk of traditional constant wattage heat tapes. Tandem-Link has become an essential product for mining camps and construction companies.
To further increase the energy efficiency of your Tandem-Link heating cable system, it is recommended to add thermal insulation and a thermostat. The additional thermal insulation works to reduce heat loss, and the thermostat allows you to duty cycle your Tandem-Link system based on external pipe temperature. When insulation and a thermostat is combined you can increase energy efficiency by as much as 80%.
Tandem-Link is an external heat tracing system designed to provide permanent or temporary reliable freeze protection of metallic and non-metallic pipes. Examples include but not limited to;
Tandem-Link is a very versatile product, and as such it can be utilized in many specialized applications. If you feel you have a special or unique application for Tandem-Link please contact Heat-Line directly and speak with one of our knowledgeable product specialists.
Determining the length of Tandem-Link that you need to fit application is very simple as the Tandem-Link system is designed to run straight along the pipe in most applications depending on pipe diameter and insulation thickness. When in doubt, order longer than expected.
To freeze protect small diameter pipes of 2 in. (51mm) inside diameter (ID) or less a single trace of heater is often enough; however in extreme cold application more insulation and or passes of heater may be required. Increasing your thickness of insulation can also minimize the require amount of Tandem-Link heating cable and vastly increases your energy efficiency.
For pipe diameters greater than 2 in. (51mm) in diameter a minimum of 2 traces of heating cable is recommended and a consultation with a Heat-Line application specialist is suggested to ensure proper performance.
If you have any specific questions regarding the required lengths of Tandem-Link for your parameters please call Heat-Line directly and speak with one of our Heat-Line application specialist. Have the following information available if possible:

A – There is no operational difference between the Tandem-Link and Paladin heating cable. The Tandem-Link system is inter-connectable with a male plug on one end of the heating cable and a female plug on the opposite end. The Paladin system is complete with a male plug on one end, and an end seal termination boot on the opposite end.
A- Yes. The Tandem-Link system is approved for use on all metallic and non-metallic pipe applications. The advance self-regulating technology employed in the Tandem-Link product renders it safe on plastic pipes even when dry as it can never overheat and damage the pipes.
A – Yes. The Tandem-Link heating cable can be buried; however the plug ends should remain above the ground.
A - Since Tandem-Link has extraordinary heat transfer properties it can be simply run straight along the pipe without the need to pitch or spiral the heater on pipe diameters of 2’’ or less. For larger pipe dimeters multiple passes or spiraling of the heating cable may be required.
A – No. A thermostat is not included with the Tandem-Link product as they are not required for proper and safe operation; however a thermostat can be purchased as an additional accessory. Depending on system applications, or where automatic operation is preferred, a thermostat can be used to switch the system on and off to help conserve power or to duty cycle the system. When combined with insulation thermostats can substantially increase energy efficiency.
A - If you have extra heater you can loop the excess back up the pipe or concentrate more heating cable in more exposed sections of the pipe. If needed it is safe for the heating cable to overlap as it is self-regulating and will not overheat.
A – No. Tandem-Link self-regulating heating cable systems increase heat output with cold but more importantly, decrease heat output with warmth. As a result, Heat-Line brand products are very energy efficient to operate, but do not completely shut off as they can only idle their output to a minimum amount. To completely shut off the system it must be unplugged or installed with a thermostat. Heat-Line brand systems should be unplugged or shut off when not required (summer months) and tested each year before use.
A - No - Energy efficiency has nothing to do with the designated voltage. We pay for the energy in watts, not in volts. Years ago the term more efficient was attached to 240 volt systems because you can put more load or amperage on a 240 volt circuit. Unfortunately the term more efficient somehow became misinterpreted to mean more energy efficient which is not the case.
A- All Heat-Line brand systems including Tandem-Link employ Heat-Line’s advanced self-regulating heating cable technology which operates to deliver energy and heat output to areas of the pipe that are cold and reduces energy and heat output to areas which are warm. While the overall amount of energy consumed depends on multiple factors you can be assured that you are installing the most energy efficient heating cable system available. If you would like to reduce your energy consumption further you can investigate the addition of a thermostat, timer, and or other control device.
A – Yes. The maximum circuit length of Tandem-Link that is allowed is as follows:
Maximum length on a 120V circuit is 205ft. (62m) AND/OR 3 connected cables
Maximum length on a 240V circuit is 410 ft. (125m) AND/OR 3 connected cables
A – Heat-Line recommends to use insulation that is best suited to the environment in which it is going to be installed. A common type of insulation employed with Tandem-Link heating cables is fire resistance water proof pipe foam insulation sleeves. You are also able to implement fiberglass insulation provided it is properly weatherproofed based on the environment.

A – Insulation is highly recommended when using the Tandem-Link system, especially if the installation is above ground in ambient outdoor air. Insulation helps reduce the overall heat loss and therefore reduce the amount of energy the Tandem-Link heating cable must consume. It also helps keep the heating cable in consistent contact with the pipe.
