Constant Wattage Heat Tracing | Eltherm ELKM-AG-N ATEX Heat Tracing Cable up to 260°C
Constant Wattage heat tracing cables
ATEX Heat Tracing Cable | Eltherm ELKM-AG-N
Eltherm ELKM-AG-N constant wattage heat tracing cables provide process temperature maintenance and frost protection to pipework, instrument lines, tanks and drums up to 260° Celsius.
These heat tracing cables manufactured by Eltherm offer flexibility in use as they can easily be cut to the required length off the roll, with the assurance of constant power output. There is no need for connecting cable and input can be unilateral. The constant wattage heat tracing cable is quick and easy to assemble, saving time and reducing operating costs.
Since the heat tracing cable output of up to 30 W/m is possible for lengths laid to piping, Eltherm ELKM-AG-N heat tracing cables are particularly suited for piping with high output requirements such as in industrial process technology. The following are applications are below:
- Pipelines
- Valves, pumps
- Tank container
- Silos, vessels, tanks
- Automotive
- Industrial Applications
- Varnishes
- IBCs
