Product details
nVent RAYCHEM BTV self-regulating trace heating cables provide frost protection and process temperature maintenance up to 65°C to pipes/vessels not subject to steam cleaning requirements. They withstand intermittent exposure to 85°C and are hazardous area approved Zone 1 and Zone 2 (Gas, Zone 21 and Zone 22 (Dust). The polyolefin outer jacket (-CR) is suitable for mild inorganic solutions. The fluoropolymer outer jacket (-CT) provides high chemical resistance against aggressive organics and corrosives
RAYCHEM BTV Features & Benefits
- Unparalleled safety: unconditional T6 temperature class, no overheating.
- Simple to design: long circuit lengths to 200 m, fewer power connections and faster installation
- Easy to install: cut to length,can be overlapped, meter markings
- Energy efficient and safe: self-regulating cable, advanced energy saving controls, major savings when used with proportional ambient sensing controller (PASC)
- Reliable long life: maintenance free, 10 year product warranty available

For more detailed information please request nVent RAYCHEM TraceCalc software design. nVent 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 - APPROVALS
