Heat Trace Freezstop Extra & Extra Wide (FSE & FSEw) Self-Regulating Heating Cable

Manufacturer: Heat Trace Ltd.

Industrial Self-Regulating Electric Heating Cable for Freeze Protection and Process Temperature Maintenance

Product Overview

The Heat Trace Freezstop Extra (FSE) and Freezstop Extra Wide (FSEw) are industrial-grade self-regulating electric heating cables designed for freeze protection and process temperature maintenance in industrial pipework, tanks, vessels and associated equipment. These heating cables provide a flexible solution for installations exposed to low ambient temperatures and demanding industrial operating conditions.

The cables incorporate self-regulating heating technology that automatically adjusts heat output according to the local temperature along the heated surface. When the surrounding pipe temperature decreases, the heating cable increases its heat output to compensate for greater heat loss. As the temperature rises, the cable reduces its output. This characteristic supports efficient heating performance under changing ambient and process conditions.

The Freezstop Extra series is available in nominal power outputs of 17 W/m and 31 W/m, while the Freezstop Extra Wide series offers higher nominal outputs of 45 W/m and 60 W/m. These ratings provide different heating capacities for industrial applications, with the appropriate selection determined by heat-loss calculations, operating temperature, supply voltage, pipe dimensions and insulation characteristics.

The FSE and FSEw product families are designed for industrial heat-tracing applications requiring reliable temperature protection, installation flexibility and long-term operational performance. Their self-regulating construction is designed to tolerate cable overlap under specified operating conditions, helping reduce the risk of localized overheating associated with conventional heating cable technologies.

The product families are available with different outer jacket materials, including thermoplastic and fluoropolymer options. These configurations allow engineers to select a suitable cable construction according to the environmental conditions, chemical exposure and mechanical requirements of the installation.

The heating cables can be cut to the required length on site, subject to the manufacturer's circuit design and installation limitations. Compatible power connection, termination, splicing and end-seal accessories can be selected to complete the heat-tracing system.

Self-Regulating Heating Technology

The FSE and FSEw heating cables use a self-regulating conductive heating element positioned between electrical conductors. The electrical properties of this heating element change with temperature, enabling the cable to adjust its local heat output according to the thermal conditions along the pipe or equipment.

When the surrounding temperature decreases, the heating element increases its heat output to help compensate for greater heat loss. When the temperature increases, the heat output decreases. This behaviour enables the heating cable to respond to local temperature variations instead of producing the same fixed heat output under all operating conditions.

The self-regulating construction is particularly useful for pipework with varying thermal conditions, where some sections may lose more heat than others. It can help improve the distribution of heating along the installation while supporting efficient temperature maintenance.

Actual heat output depends on the cable model, supply voltage, pipe temperature, installation arrangement and surrounding conditions. A heat-loss calculation and reference to the manufacturer's output data are necessary to confirm that the selected cable can maintain the required temperature.

Freezstop Extra (FSE)

Freezstop Extra is designed for industrial freeze protection and process temperature maintenance applications requiring nominal heating outputs of 17 W/m or 31 W/m. The series provides a flexible solution for suitable piping systems and industrial equipment where reliable thermal protection is required.

The FSE series is available with different outer jacket configurations to accommodate varying environmental and chemical exposure conditions. The thermoplastic-jacketed version may be considered for suitable general industrial applications, while the fluoropolymer-jacketed version is intended for applications where the selected fluoropolymer construction is appropriate.

The appropriate FSE model must be selected according to calculated heat loss, required maintenance temperature, minimum ambient temperature, pipe dimensions, insulation properties and electrical design limitations.

Freezstop Extra Wide (FSEw)

Freezstop Extra Wide is designed for applications requiring higher nominal heating outputs than those offered by the standard FSE series. Available nominal power outputs are 45 W/m and 60 W/m, making the series suitable for evaluation in installations with greater calculated heat-loss requirements.

The FSEw series offers the same general benefits associated with self-regulating heating technology, including temperature-responsive output, installation flexibility and the ability to cut the cable to the required length in accordance with the manufacturer's requirements.

The higher nominal output does not automatically guarantee suitability for every high-heat-loss application. The designer must verify cable output at the required maintenance temperature, the maximum permissible exposure temperature, circuit length and electrical protection requirements.

Inherent Temperature Safety and Cable Overlap

The self-regulating design of the FSE and FSEw product families is intended to tolerate cable overlap under specified operating conditions. This characteristic helps reduce the risk of localized overheating associated with certain conventional heating cable technologies.

Self-regulating performance does not remove the need for correct installation, suitable electrical protection, appropriate temperature monitoring where required, or compliance with the manufacturer's maximum operating limits.

The maximum continuous exposure temperature in the energized state and maximum permissible exposure temperature in the de-energized state are specified as 100°C (212°F) for the applicable product configurations. These limits must be observed when selecting the cable for the intended process.

Outer Jacket Options and Environmental Resistance

The FSE and FSEw product families are available with thermoplastic and fluoropolymer outer jacket options. These jacket configurations allow the cable to be matched to different environmental conditions and installation requirements.

Thermoplastic and fluoropolymer materials have different chemical resistance and application characteristics. The appropriate jacket must be selected according to the substances present, operating temperature, moisture exposure, mechanical conditions and relevant product approvals.

The fluoropolymer-jacketed versions may be considered for compatible applications requiring enhanced resistance to certain corrosive environments. However, suitability must be verified against the actual chemicals, concentrations and operating conditions involved.

Heating Cable Selection and Power Ratings

Selecting the correct heating cable requires an assessment of the thermal requirements of the installation. The FSE series offers nominal power outputs of 17 W/m and 31 W/m, while the FSEw series offers 45 W/m and 60 W/m.

The nominal power output must be evaluated using the manufacturer's specified reference conditions and output-versus-temperature data. Actual heat generation varies according to operating temperature and supply voltage.

The selection process should account for pipe diameter, pipe material, minimum ambient temperature, required maintenance temperature, insulation type and thickness, pipe length, valves, flanges, supports and other points of additional heat loss.

Hazardous Area Applications

The FSE and FSEw series may be suitable for selected hazardous and non-hazardous area installations, depending on the exact cable configuration and applicable product approvals. The availability of an approved version must be confirmed before the cable is specified for a classified location.

Hazardous-area suitability depends on the product reference, nominal power output, temperature classification, supply voltage, installation method and conditions stated in the relevant certification documents.

For installations involving flammable gases, vapours or combustible dust, the design must account for the permitted surface temperature, process conditions, electrical protection, termination accessories and applicable hazardous-area regulations. The stated maximum exposure temperature must not be used as a substitute for verifying the certified temperature classification.

Installation and Mounting Guidelines

Proper installation is essential for reliable performance, electrical safety and long service life. Before installation, inspect the pipe or equipment surface and remove sharp edges, burrs and contaminants that could damage the heating cable.

Position and secure the cable in accordance with the manufacturer's recommended arrangement. Avoid excessive mechanical tension, crushing, sharp bends or damage to the outer jacket. Observe the specified minimum bending radius and installation spacing requirements for the exact cable model.

Where thermal insulation is required, it should be selected according to the design temperature and environmental conditions. Insulation thickness and material have a significant effect on heat loss and must be included in the heating circuit design.

Use compatible power connection kits, end seals, splices, junction boxes and cable glands. Electrical connections and terminations must be completed by qualified personnel in accordance with the manufacturer's instructions and applicable electrical regulations.

After installation, carry out the required electrical and visual inspections before the system is energised. Where applicable, perform continuity and insulation resistance tests before and after the installation of thermal insulation. Record the results for commissioning and future maintenance.

Recommended Accessories

• Compatible power connection kits for the selected FSE or FSEw model.
• Approved end-seal kits suitable for the cable configuration.
• Compatible splicing kits where intermediate cable connections are required.
• Suitable junction boxes and cable glands.
• Electrical circuit protection devices selected according to the cable specifications and circuit design.
• Appropriate cable attachment materials and installation accessories.
• Thermal insulation and weatherproofing materials suitable for the application.
• Temperature monitoring and control equipment where required by the system design.

Accessory compatibility must be verified for the exact FSE or FSEw cable configuration. Do not assume that a termination or connection kit designed for another heating cable series is suitable without confirmation from the manufacturer.

Circuit Length and Electrical Protection

The maximum permissible circuit length depends on the selected cable model, nominal power output, supply voltage, circuit-breaker rating and expected start-up temperature. Self-regulating heating cables may draw higher current during cold start-up, making these factors essential when designing the electrical distribution system.

Circuit-breaker selection and permissible circuit length must be determined using the manufacturer's electrical design data. Nominal power output alone is insufficient to determine the maximum cable length or appropriate protective device.

The electrical design must also consider supply cable sizing, protective earthing, residual-current or ground-fault protection where required, and the applicable electrical and hazardous-area standards.

Temperature Control and Energy Efficiency

The self-regulating characteristic of FSE and FSEw cables enables the heating output to respond automatically to local temperature changes. However, self-regulation does not eliminate the need for correct system design or temperature control where precise process conditions must be maintained.

A suitable thermostat, temperature controller or monitoring system may be required depending on the application, operating conditions and applicable regulations. The control method should be selected in accordance with the process requirements and manufacturer's recommendations.

Correct insulation, appropriate cable sizing and properly designed electrical circuits are essential for efficient operation. Insufficient heating capacity, excessive heat loss or an incorrectly designed circuit can prevent the system from achieving the required maintenance temperature.

Maintenance and Inspection

Periodic inspection helps maintain the reliability and safety of an industrial heat-tracing system. Recommended activities include visual inspection of accessible cable sections, examination of electrical connections, verification of insulation integrity and testing of protective devices and temperature controls where applicable.

Following pipework modifications, insulation removal or mechanical maintenance, the heating circuit should be inspected and tested before the system is returned to service.

Any damaged cable, defective termination or abnormal electrical test result must be investigated and corrected in accordance with the manufacturer's maintenance procedures. Damaged heating cables must not be energised until their condition has been assessed and the necessary corrective action has been completed.

Design and Safety Considerations

• Calculate the heat loss of the pipe or vessel before selecting the cable.
• Confirm the required process temperature and minimum ambient temperature.
• Select the correct FSE or FSEw power output according to the design requirements.
• Verify the cable's maximum exposure temperature and applicable temperature classification.
• Confirm the supply voltage, circuit length and cold-start current.
• Use compatible and approved electrical connection and termination accessories.
• Observe the specified cable bending radius and installation requirements.
• Verify chemical compatibility and outer jacket suitability for the installation environment.
• Confirm the exact hazardous-area approvals where applicable.
• Provide appropriate electrical protection, grounding and testing.
• Follow the manufacturer's installation, commissioning and maintenance instructions.
