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.

How Eltherm ELP/PFA Heater Cables Function

ELP/PFA Heating circuit length

Heat Tracing Cable Type	Power [W/m]	Length @ start up temp. [m]
ELP/PFA 15 BOT	15.0	184.0
ELP/PFA 30 BOT	30.0	100.0
ELP/PFA 45 BOT	45.0	66.0
ELP/PFA 60 BOT	60.0	50.0

Heating circuit length factor 230 V vs. 277 V = 0,83

Note:

Heating circuit lengths ELP/PFA on the following conditions:

16 A circuit breaker, 80 % utilisation, start up temp. +10°C
Max. 10% voltage drop
Power connection to one (1) heater end

Greater lengths are possible with higher rated circuit breakers, please contact T&D
Cables shall neither intersect nor contact
Provide protection by means of circuit breaker RCD 30 mA
Please observe the standards: IEC 62395-2, EN 60519-10, EN 62395-2
