  • Raychem trace heating cable - self regulating

    Raychem self regulating trace heating cable automatically adjusts the power output to compensate for temperature changes. Raychem self regulating trace heating cables consist of two parallel conductors embedded in a heating core made of conductive polymer. Since the invention by Raychem of self regulating heat trace heating cable over 40 years ago, more than 500,000 km of Raychem self regulating heat trace heating cables are now installed successfully worldwide, offering proven and reliable electric heat trace heating systems. Some of the many benefits of self regulating heat trace heating cables are; • Easy installation as cables may be cut to length and be overlapped at valves or flanges • Uniform temperatures, as the heating cable senses and responds to actual conditions • Unconditional T-ratings as specified by European Norm EN 60079-30-1 • Maximum process temperatures, even when temperature controls fail • Operating voltages up to 277 V • Temperature maintenance up to 150°C • Circuit lengths up to 245 m Raychem self regulating heat trace heating system technology is available in BTV, QTVR, KTV, XTV or VPL heating tape ranges of products. Suitable for a diverse range of applications in construction for larger buildings, industry and hazardous area locations.

  • Raychem series resistance trace heating cable

    Raychem flexible series-resistance heating cables can be used when circuit lengths exceed the ratings of conventional parallel-resistance heating cables and a single power source is needed. Ohmic heating of the conductor provides the heat in this series circuit heating cable. Engineering design is necessary since the wattage output depends on the total circuit length and the voltage applied. SC cables are available with one or two conductors for single phase or three phase systems. The resistance conductors are electrically isolated with high-temperature, heavy-wall fluoropolymers; a grounding braid; and a final fluoropolymer jacket. Maximum maintain temperatures to 250°F (121°C) and exposure temperatures of up to 482°F (250°C) are available. SC cables are capable of circuit lengths up to 12,000 feet with one power supply point and voltages up to 600 Vac.

  • Raychem power limiting trace heating cable

    Raychem power limiting heating cables allow for higher exposure temperature and higher power output at elevated temperatures.Raychem power-limiting cables are parallel heaters formed by a coiled resistor alloy heating element wrapped around two parallel bus wires. At a fixed distance, the insulation is removed from the alternate bus wires to form a heating zone.The positive temperature coefficient effect (PTC) of the heating element reduces power output as ambient temperature increases. This effect allows the power-limiting cable to be overlapped by reducing the temperature of the heating element at the overlap points.Raychem power limiting cable can be used for freeze protection and process temperature maintenance requiring high power output and/or high temperature exposure. Raychem power limiting cables can provide process temperature maintenance up to 455°F (235°C) and can withstand exposure temperatures up to 500°F (260°C) with power off.

  • Raychem constant wattage trace heating cable

    Raychem constant wattage zone parallel trace heating cables use a resistive alloy heating element wrapped around two parallel bus wires.At fixed distances, the insulation is removed from the bus wires on alternating sides. This distance between contact points forms the heating zone length.The parallel construction allows these cables to be cut to length on site. The unique round construction ensures high flexibility, but typically require more sophisticated control systems and the cable must not be overlapped.Raychem constant wattage parallel trace heating systems offer an economical alternative while maintaining the advantages of cut-to length cables. Because of their constant power output, circuit breaker sizes may be reduced compared to self-regulating trace heating systems. For line lengths of up to 200 m, for maintain temperatures of up to 200°C.
