Constant Wattage Heat Tracing | Eltherm ELP/PFA ATEX Heat Tracing Cable up to 260°C

Product Overview

Constant Wattage heat tracing

ATEX Heat Tracing Cable | Eltherm ELP/PFA

Eltherm ELP/PFA constant wattage heat tracing cables provide process temperature maintenance and frost protection to pipework, instrument lines, tanks and drums up to 260° Celsius – with IECEx and ATEX Certification Eltherm ELP/PFA heat tracing are suitable for Zone 1 and Zone 2 hazardous areas.

These parallel trace heaters offer tremendous 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 a connecting cable and input can be unilateral. The constant wattage trace heating cable is quick and easy to assemble and therefore saves time and reduces operating costs.

Since output of up to 60 W/m is possible for lengths laid to piping, ELP/FA parallel trace heating cables are particularly suitable for piping with high output requirements such as in industrial process technology. Industries and applications were the heat tracing cables are used are as follows:

• Valves, pumps
• Pipelines
• Food Processing Industry
• Paper Industry
• Building construction

Eltherm ELP/PFA Benefits

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

The ELP/PFA is guaranteed a long life by the fluoropolymer’s high degree of chemical resistance and its very temperature-resistant outer layer.

Constant wattage heating cables such as the ELP/PFA 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.
