|Range||Raychem VPL Self Regulating Heating Cable|
VPL is a family of power limiting heating cables designed for pipe and equipment heat-tracing in industrial applications.
VPL can be used for frost protection and process temperature maintenance requiring high power output and/or high temperature exposure. VPL can provide process temperature maintenance up to 235°C (depending on cable type) and can withstand routine steam purges and temperature exposure to 260°C with power off.
Power-limiting cables are parallel heaters formed by a coiled resistor alloy heating element wrapped around
two parallel conductors. The distance between conductor contact points forms the heating zone length. This parallel construction allows it to be cut-to-length and terminated on-site. The power output of VPL heating cables decreases with increasing temperature. VPL heating cables can be overlapped once. The relatively ﬂat power temperature curve of VPL ensures a low start-up current and high output at elevated temperatures. VPL cables are approved for use in hazardous areas. Approvals are listed below.
- Hazardous, Zone 1, Zone 2 (Gas), Zone 21, Zone 22 (Dust)
Traced Surface Type:
- Carbon steel
- Stainless steel
- Painted or unpainted metal
- Organics and corrosives
- For aggressive organics and corrosives consult your local Pentair representative
The VPL heating cables are approved for use in hazardous areas by Baseefa Ltd.
- Baseefa06ATEX0188X & IECExBAS06.0048X
- II 2GD & Exe II T* (see schedule) Ex tD A21 IP66

*By design. Temperature classiﬁcation (T-rating) has to be established by using the principles of stabilized design or the use of a temperature limiting device. Use TraceCalc design software or contact Pentair.
Maximum Circuit Length
Based on type 'C' circuit breakers according to EN 60898
|Electrical Protection Sizing||Start Up Temperature||Maximum Heating Cable length per circuit(M)|
*The maximum heating cable length must not exceed these values, even when voltage adjustment factors are used.
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 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
Yes, when using trace heating on plastic pipes ensure that ATE- 180 aluminium tape is used to help disperse the heat around the pipe.
Yes, utilising our in-house design facilities, we can design your complete trace heating requirement.
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 ...
Most applications can simply be straight traced, reducing costs of materials and installation time without compromising on operational requirements.
Yes, thermal insulation is required on all heat trace applications. Without insulation, surface heat losses can increase approximately 4-5 times.
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...
