Self-Limiting Ex Heating Cable 31 W/m for Industrial Pipe Trace Heating
The HTP EX self-limiting heating cable has been developed for demanding pipe trace heating applications and use under challenging environmental conditions. Its suitability for appropriately designed explosion-protected applications is a key feature: the heating cable is approved according to ATEX and IECEx and is classified in ATEX temperature class T4.
This makes the HTP EX suitable for industrial applications where reliable heating and increased explosion protection requirements are essential. Its specific suitability for the relevant Ex zone and installation must be verified on the basis of the complete Ex marking, the system design and the required connection components.
The self-regulating heating matrix automatically adjusts the heat output to the ambient temperature. When the temperature drops, the heat output increases. As the temperature rises, the output is automatically reduced. This supports energy-efficient and reliable frost protection as well as dependable temperature maintenance on pipes.
With a nominal output of 31 W/m at 10 °C, the heating cable is suitable both for installation on the outside of pipes and for installation inside suitable pipe systems. The durable fluoropolymer outer jacket allows use under increased temperature and environmental requirements. The maximum permissible cable temperature is 110 °C when energized and 135 °C when de-energized.
For controlled and economical operation, regulation via a suitable thermostat with a temperature sensor matched to the application is recommended.

Notes
To place an order, enter the required number of metres as the quantity in the shopping cart. The ordered quantity will be supplied as one corresponding continuous length of heating cable.
Example: An order quantity of 30 units corresponds to a delivery of 30 metres of heating cable in one continuous length.
The HTP EX heating cable is not supplied ready for connection. Suitable connection and end termination components, as well as a thermostat if required, are necessary for operation.
In hazardous areas, only project-specific approved ATEX system components may be used. Planning, connection and installation must be carried out by qualified professionals.
Suitability for the relevant Ex zone, gas or dust group, temperature class and installation must be fully verified before installation. When installed inside a pipe, compatibility with the pipe material, medium and operating conditions must also be ensured.
