Hazardous Location Heat Trace Cable

Self-regulating heat trace cable rated for classified environments, like refineries, O&G pipelines, chemical processing, and industrial areas where flammable gases or vapors are present. FM certified, UL Listed, CSA Approved.

Hazardous Location Cable

Self-regulating cable built and certified for classified hazardous locations. Available in 5W and 8W. Both carry the certifications required for Class I Division 2 environments, the same self-regulating core as standard cable, with a construction rated for where it's going.

Certifications & Approvals

FloTrace hazardous location cable carries the certifications required for classified industrial environments. If a job spec calls for specific approvals, verify against the product datasheet before ordering.

Class I Div 2 FM Approved UL Listed CSA Approved NEPSI Certified

Common Applications and Areas for HazLoc Cable

Hazardous location cable is specified wherever a classified atmosphere is present and standard cable isn't approved for the environment.

⛽

Oil & Gas Pipelines

Freeze protection and flow assurance on O&G lines in classified areas.

🏭

Refineries

Pipe freeze protection and process temperature maintenance in refinery environments.

⚗

Chemical Processing

Freeze protection and line temperature maintenance around flammable chemical processes.

◇

Instrument Tubing

Keeping instrument lines above freezing in classified outdoor or process areas.

Built for Classified Environments

The self-regulating technology works the same as standard cable. What changes is the construction, testing, and certification — everything required to install in a location where flammable gases or vapors may be present.

01

Rated for the environment

Standard polyolefin and fluoropolymer cable are not approved for classified locations. HazLoc cable is specifically built and tested for environments where ignition risk is a factor.

02

Same self-regulating core

Automatically adjusts heat output based on ambient temperature. No thermostat required for basic applications. Can overlap without overheating. Cut to length on site.

03

Certs that match the spec

FM, UL, CSA, and NEPSI approvals are documented on the product datasheet. If the job spec calls for specific certifications, verify against the datasheet before ordering.

How HazLoc Compares to Standard Cable

Here is how hazardous location self-regulating heat trace cable compares to regular cable:

PROPERTY STANDARD POLYOLEFIN FLUOROPOLYMER HAZARDOUS LOCATION
Classified locations Not approved Not approved Class I Div 2 rated
Chemical resistance Standard High High
Self-regulating core Yes Yes Yes
Available wattages 5W · 8W · 10W 5W · 8W 5W · 8W

Haz-Loc Heat Trace FAQ

What makes a location "classified" for heat trace purposes?

A classified location is one where flammable gases, vapors, or combustible dusts may be present in concentrations that could ignite. Under NEC Article 500, these are divided into Classes (based on the type of hazard), Divisions (based on likelihood of the hazard being present), and Groups (based on the specific material). Class I Division 2 covers areas where flammable vapors or gases are handled but not normally present in ignitable concentrations — the most common classification for O&G, refinery, and chemical processing environments where heat trace is used.

Can I use standard polyolefin or fluoropolymer cable in a hazardous location?

No. Standard polyolefin and fluoropolymer cable are not rated or certified for classified hazardous locations. Using non-rated cable in a classified environment is a code violation and an ignition risk. If the location is classified, the cable has to be rated for it.

Is FloTrace haz-loc cable rated for Class I Division 1?

FloTrace hazardous location cable is rated for Class I Division 2. Division 1 covers areas where hazardous concentrations exist continuously or intermittently under normal conditions — a more demanding rating. If your application requires Division 1 rated cable, contact us before ordering and we can confirm whether the product is appropriate for your spec.

What certifications does the cable carry?

FM Approved, UL Listed, CSA Approved, and NEPSI Certified. Full certification documentation is available on the individual product pages. If a specific certification is required by your project spec, verify against the datasheet before ordering or contact us with your requirements.

Does hazardous location cable still self-regulate?

Yes. The self-regulating core works the same as standard cable — it adjusts heat output automatically based on ambient temperature, can overlap without overheating, and can be cut to length on site. The hazardous location rating is about the construction and certification, not a change to how the cable functions.

Do I need special accessories for haz-loc installations?

Yes. Junction boxes, power connection kits, and other components used in classified locations also need to be rated for the environment. Standard accessories are not appropriate for haz-loc installations. Contact us for guidance on compatible components for your specific application.
