|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.
Traced Surface Type:
The QTVR heating cables are approved for use in hazardous areas by PTB and Baseefa Ltd:
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||51|
|Temperature Classification||T4 in accordance with European Standard EN 60079-30-1 5.1.13|
We make every effort in answering your questions. Below is a list of those questions we are frequently asked. Click on a question to expand its answer.
Self limiting / self regulating heating tape adjusts heat output to equal the heat loss from the pipe work. As pipe temperature falls the electrical conductivity of the semi-conductive core increas...
Yes, utilising our in-house design facilities, we can design your complete trace heating requirement.
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, thermal insulation is required on all heat trace applications. Without insulation, surface heat losses can increase approximately 4-5 times.
Most applications can simply be straight traced, reducing costs of materials and installation time without compromising on operational requirements.
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 ...
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...
System checks depend on the system installed, constant wattage systems can be fully checked for insulation resistance and continuity. Self regulating systems can only be checked for insulation resi...
This is used for a pipe freeze protection application. Electric heat tracing, heat tape or surface heating, is a system used to maintain or raise the temperature of pipes and vessels. Trace heat...
