Electrical heat-tracing for frost protection without steam cleaning.

The BTV-family of self-regulating, parallel circuit heating cables is used for frost protection of pipes and vessels.

It can also be used for process temperature maintenance up to 65°C.


Area Classification:

  • Hazardous, Zone 1, Zone 2 (Gas), Zone 21, Zone 22 (Dust)
  • Ordinary

Traced surface type:

  • Carbon Steel
  • Stainless Steel
  • Plastic
  • Painted or unpainted metal

Chemical resistance:

  • For organic corrosives: use -CT (fluoropolymer outer jacket)
  • For mild inorganic solutions: use -CR (modified polyolefin outer jacket)
  • For aggressive organics and corrosives consult your local Pentair representative

Pentair requires the use of a 30 mA residual current device to provide maximum safety and protection from fire.

Where design results in higher leakage current, the preferred trip level for adjustable devices is 30 mA above any inherent capacitive leakage characteristic of the heater as specified by the trace heater supplier or alternatively, the next common available trip level for non adjustable devices, with a maximum of 300 mA. All safety aspects need to be proven.

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.

Read more

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.

Read more

How do I terminate the heating cable?

Full termination instructions are provided with all our heating tapes

Read more

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...

Read more

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...
