FMT and FHT are constant wattage parallel circuit heating cables designed for pipe and equipment heat-tracing in industrial applications. This family offers an economical alternative to self-regulating heating cables but requires more skill for installation and also requires more advanced control and monitoring systems.

Its unique round geometry provides excellent flexibility during installation as it allows for bending in every direction. The heating element which is the most fragile part of any constant wattage parallel circuit heating cable is protected by a PTFE insulation tape that eliminates shear stresses during flexing and also acts as a shock absorber, thereby providing a high level of protection. The heating cables can be used for frost protection and process temperature maintenance requiring high power output. The heating cables are zone parallel heaters constructed from a heating element wrapped around two parallel conductors. The distance between conductor contact points forms the heating zone length. The parallel construction allows it to be cut-to-length and terminated in the field.

FMT heating cables can withstand routine steam purges and temperature exposure to 200°C power off. They can be used to maintain temperatures up to 150°C (depending on cable type) and are only available in a 230 Vac version.

Frequently Asked Questions

We make every effort in answering your questions. Below is a list of those questions we are frequently asked. Click on a question to expand its answer.

What is self regulating heating tape?

Self limiting / self regulating heating tape adjusts heat output to equal the heat loss from the pipe work. As pipe temperature falls the electrical conductivity of the semi-conductive core increas...

Can you design a full surface heating system for me?

Yes, utilising our in-house design facilities, we can design your complete trace heating requirement.

Can I use heat trace on plastic pipes?

Yes, when using trace heating on plastic pipes ensure that ATE- 180 aluminium tape is used to help disperse the heat around the pipe.

Read more

Do I need to use thermal insulation?

Yes, thermal insulation is required on all heat trace applications. Without insulation, surface heat losses can increase approximately 4-5 times.

Read more

Do I have to spiral the trace heating onto the pipe?

Most applications can simply be straight traced, reducing costs of materials and installation time without compromising on operational requirements.

How do I terminate the heating cable?

Full termination instructions are provided with all our heating tapes

Do I have to allow extra heat for pumps and valves?

If the surface area of the pump is substantially greater than that of the adjoining pipework then extra heating cable may need to be considered (depending on wattage of cable installed). Pumps and ...

Does my trace heating system require maintenance?

Generally, no maintenance of our trace heating systems is required but it is recommended that the system is checked for operational and electrical integrity periodically or prior to the winter or p...

How do I test my trace heating system is working properly?

System checks depend on the system installed, constant wattage systems can be fully checked for insulation resistance and continuity. Self regulating systems can only be checked for insulation resi...

What is Heat Trace?

This is used for a pipe freeze protection application. Electric heat tracing, heat tape or surface heating, is a system used to maintain or raise the temperature of pipes and vessels. Trace heat...

What is heat tape for water pipes?

When water pipes are exposed to cold temperatures either outdoors, underground or in small spaces, you can protect them from freezing by wrapping them with heat tape. Heating tape is actually a cor...
