Constant Wattage heat tracing Cables

Industrial Heat Tracing Cable | Eltherm ELP/Si-F

Eltherm ELP/Si-F constant wattage heat tracing cables provide process temperature maintenance and frost protection to pipework, instrument lines, tanks and drums up to 200° 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 trace heater cable output of up to 40 W/m is possible for lengths laid to piping, Eltherm ELP/Si-F heat tracing cables are particularly suited for piping with high output requirements such as in industrial process technology. The following are applications are below: 

• Chemistry & Petrochemistry
• Building Construction
• Food Processing Industry
• Paper Industry
• Process Industries

Eltherm ELP/Si – F Heating Cable Benefits

• Single end power input
• Trace heating cable can be cut from the cable drum
• Constant power output per meter
• Long life cycle
• Laying without exact measuring possible
• High chemical resistance
• UV resistance heating cables
• Moisture proof

Constant wattage heating cables such as the ELP/Si consist of a succession of heating zones (length = contact spacing) and can be cut to length in sections of the contact distance to the required length – when cutting heater cables into lengths, the heating circuit is interrupted up to the next contact point and this non-active part can be used as a cold lead.

CONSTANT WATTAGE HEATING CABLES

Constant wattage heating cables consist of a succession of heating zones (length = contact spacing) and can be cut to length in sections of the contact distance to the required length – when cutting heater cables into lengths, the heating circuit is interrupted up to the next contact point and this non-active part can be used as a cold lead.

Constant wattage heater cable when installed onto pipework for frost protection or process temperature maintenance must not intersect, contact or overlap to prevent overheating.

Self-regulating heating cables can be overlapped without risk of burn-out or overheating.
