Eltherm ELKM-AS Constant Wattage Heat Tracing Cable

Constant Wattage heat tracing cables

ATEX Heat Tracing Cable | Eltherm ELKM-AS

Eltherm ELKM-AS 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.

Eltherm resistance heating cables are manufactured from a high-resistance heating conductor, PTFE insulated with protective braid and fluoropolymer outer jacket. Powered at specific voltage the resistance heat generated by the conductors provides electrical trace heating to pipes and vessels. Resistance heating cables will “burn-out” if overlapped unlike self-regulating trace heating cables.

Since the heat tracing cable output of up to 30 W/m is possible for lengths laid to piping, Eltherm ELKM-AE heat tracing cables are particularly suited for piping with high output requirements such as in industrial process technology. The following are applications are below:

Silos, vessels, tanks
Valves, pumps
Pipelines
Industrial Applications
Rotor blade tips

Eltherm ELKM-AS resistance heating cables and tapes provide process temperature maintenance and frost protection to vessels, pipes, valves and small components up to 260° Celsius.
