Electrical heat-tracing for frost protection without steam cleaning.
The nVent RAYCHEM 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.
Application
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

The above numbers are for circuit length estimation only. For more detailed information please use the Pentair TraceCalc software or Contact your local Pentair representative.
Pentair requires the use of a 30 mA residual current device to provide maximum safety and protection from ï¬Âre.
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 speciï¬Âed 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.
