Raychem 20QTVR2-CT Self Regulating Trace Heating Cable
Quick Find: 1250
Part Code: 988967-000
|Range||Pentair Raychem QTVR Self Regulating Heating Cable|
Electrical heat-tracing for process temperature maintenance applications up to 110°C which are not subject to steam cleaning.
The QTVR family of self-regulating, parallel circuit heating cables is used for process temperature maintenance of pipes and vessels.
It can also be used for frost protection of large pipes and for applications requiring medium temperature exposure capability.

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 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.
|Maximum maintain or continuous exposure temperature (power on)||110 °C|
|Minimum bend radius||At -60°C: 35 mm|
|Minimum bend radius||At 20°C: 13 mm|
|Minimum installation temperature||-60 °C|
|Nominal Power Output||64 at 10 °C|
|Temperature Classification||T4 in accordance with European Standard EN 60079-30-1 5.1.13|
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...
