CARAPACE® Job-Ready

CARAPACE is a high-performance, freeze-protected water pipe system ideal for high-pressure or long length systems. The innovative system is constructed of 200 PSI polyethylene pipe with Heat-Line self-regulating heating cable extruded directly onto the pipe surface, protected by a shell of high-density polyethylene. The patented construction of CARAPACE provides superior thermal heat transfer and unsurpassed energy efficiency while ensuring reliable frost protection for pipes. CARAPACE is certified drinking water safe for potability and is suitable for direct earth burial, and free air installations. CARAPACE provides a cost-effective solution when natural frost protection is unavailable, eliminating the need for expensive blasting and excavation methods.

Features

CARAPACE is available as a job-ready plug-in frost protection pipe with GFCI protection with a 4ft. (1.2m) power lead and is factory finished to length making installation simple, fast, and cost-effective. The need for an electrician to provide on-site power and complex terminations is eliminated. Other power supply options are also available.

The CARAPACE job-ready frost protection pipe system is supplied pre-assembled ready for installation. To install, simply roll out the pipe and connect using industry-standard plumbing fittings such as Philmac 3G Compression fitting supplied by Heat-Line. CARAPACE is constructed using a high-density NSF STD 14 approved polyethylene pipe for high strength and portability. The self-regulating heating cable is extruded directly onto the outer surface of the frost protection pipe with a thin layer of high-density polythene. The extruded layer provides a protective shell to guard against mechanical injury while ensuring the conductive self-regulating heating cable remains in unyielding contact with the pipe wall. This unique construction makes CARAPACE the only product Heat-Line recommends for use with high pressure and constant pressure water supply systems, making it the ideal choice for pipe frost protection, and preventing pipes from freezing in high pressure applications such as residential water supply lines. Protecting pipes from freezing has never been easier!

CARAPACE provides frost protection for pipes by using the unique and advanced performance of self-regulating heating cable technology, thus effectively preventing frozen pipes. CARAPACE can effectively increase heat and energy output to sections along its length which are cold and simultaneously reduce heat and energy output to sections that are warm, which effectively keeps pipes from freezing. You never have to worry about CARAPACE overheating causing the risk of melting and fire because of the self-regulating heat tracing cable technology. Even in applications where pipes are intended to be dry for short or extended periods of time, CARAPACE will never over-heat or melt the pipe. CARAPACE gives you the peace of mind of reliable freeze protection and frost protection for pipes without the risk. It has become an essential product for homeowners, farmers, and engineers overseeing municipal projects due to its high effectiveness in frost protection for pipes, preventing frozen pipes, and protecting water pipes from freezing. If you’re looking for a way to protect pipes from freezing or preventing pipes from freezing, CARAPACE is the heat tracing technology for you!

To further increase the energy efficiency of your CARAPACE frost protection pipe 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 CARAPACE system based on external pipe temperature. Both accessories combined can increase energy efficiency by as much as 80%. In applications where pipes will be exposed to atmospheric (free) air, closed-cell or other approved weatherproof insulation is required. Insulation will help to maintain energy efficiency and cold temperature reliability. Insulation is recommended for use in all new applications; however, any pipe subjected to outside air must be completely insulated to retain the heat within the pipe. Preventing pipes from freezing has never been easier!

Measuring Recommendations for CARAPACE

Always measure prior to ordering. Do not assume or estimate the length required.

– The CARAPACE system is an advanced water supply pipe and self-regulating heating cable system factory finished and supplied job-ready to a pre-determined length provided at the time of order.

– CARAPACE systems are priced and manufactured in standard lengths of 5 ft. (1.5m) increments up to 100 ft. (30m), then in 10 ft. (3m) increments from 100 ft. to 660 ft. (30m – 201m).

Important Notes:

– There is no way to lengthen the CARAPACE product when on-site; however, with the help of a professional electrician and a Heat-Line CARPACE End Seal Kit a CARAPACE system can be shortened on-site.

– While most CARAPACE systems are manufactured in standard lengths, special lengths of any measurement can also be requested within the maximum lengths allowed. For example, if a 118ft. (36m) system was required, instead of purchasing a 120ft (36.5m) system, a special order could be placed for an exact length of 118ft (36m).

Lake/River Applications

– In a lake and or river installations, the CARAPACE system should start in the heated building or room and end (terminate) in the lake at a minimum total water depth that is greater than the expected depth of surface ice. In some applications, the Carapace system may extend right to the foot valve or submersible pump in the lake.

Well Applications

– In a drilled or dug well application the CARAPACE system should start in the heated building or room and end (terminate) at the well casing.

– In certain dug well applications, depending on the casing diameter and depth, you may be able to run the length of CARAPCE directly into the well casing prior to interfacing to the non-heated water pipe to extend to the foot valve and or pump.

– As in all cases, if you are unfamiliar or uncomfortable with the measuring and/or installation of a Heat-Line product please consult directly with a Heat-Line application specialist or contact a qualified local tradesperson.

– CARAPACE is a very versatile product, and as such it can be utilized in many specialized applications.

CARAPACE Job-Ready (Pre-Assembled) Product Code Guide

CARAPACE Job Ready Product Code Guide

 

Q – Can CARAPACE be buried?
A – Yes. The CARAPACE system is certified for direct burial and wet locations making the heating cable and proprietary end-seal termination completely safe to burry.

Q – Do I need to purchase a CARAPACE Power Connection and End Seal Termination Kit with cut-to-length CARAPACE?
A – Yes. The CARAPACE system requires a single power connection and end seal termination kit to complete an entire system length. Only Heat-Line CARAPACE Power Connection and End Seal Termination kits are approved for installation with the CARAPACE system. Using any other power connection and end seal kit will result in the cCSAus certification to be void, and any warranties on behalf of Heat-Line will be declined.

Q – Does CARAPACE come with a thermostat?
A – No. A thermostat is not included with the CARAPACE system 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.

Q – Can I (the homeowner) install cut-to-length CARAPACE?
A – No. The CARAPACE cut-to-length product is a professional use only product. As the CARAPACE cut-to-length product is not factory terminated, a licensed electrician must perform the power and end seal terminations. CARAPACE is available as a job-ready, factory terminated system. See CARAPACE job-ready.

Q – Does the unit shut off when not required?
A – No. CARAPACE 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.

Q – Does a 240-volt system use less power than a 120-volt system?
A – A common misconception is that a 240V electrical appliance consumes less energy than a 120V electrical appliance. Power consumption is measured in watts, not voltage. Whether you are consuming 500W at 120V or 500W at 240V you are still consuming 500W of energy.

Q – How much power does a CARAPACE system consume?
A – All Heat-Line brand systems including CARAPACE 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. Also see CARAPACE Energy Study for further information.

Q- Is there a maximum length of CARAPACE heating cable systems?
A – Yes. The maximum circuit length of CARAPACE that is allowed on a 120V circuit is 240ft. (73m), or 660ft. (201m) on a 240V circuit.

Q – My CARAPACE system is too short; can I add a small section onto the end? If not, what can be done?
A – No. The CARAPACE system is an advanced self-regulating heating cable system that incorporates a fluoropolymer heating cable jacket engineered to be certified for direct burial and wet locations. As such the CARAPACE system cannot be spliced together in the field. If a greater length of CARAPACE is required you may purchase a single continuous product of the proper length, and or relocate a second power source and install an additional CARAPACE system to complete the required freeze protection.

Q- What type of insulation should I use with the CARAPACE system?
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 CARAPACE heating cables is waterproof pipe foam insulation sleeves. You are also able to implement fiberglass insulation provided it is properly weatherproofed based on the environment.

Q – Where do I purchase the CARAPACE heating cable system?
A – The CARAPACE heating cable system manufactured by Heat-Line is available directly through Heat-Line and or any of our Heat-Line product distributors. For a list of Heat-Line product distributors in Canada and the United States please contact Heat-Line directly on our toll-free number at 800-584-4944.

Q – Do I have to use insulation with the CARAPACE system?
A – Insulation is highly recommended when using the CARAPACE system, especially if the installation is above ground in ambient outdoor air. Insulation helps reduce the overall heat loss and therefore reduces the amount of energy the CARAPACE heating cable must consume.
