How to Choose Heat Tracing Cable: Self-Regulating vs Constant Wattage vs MI

Frequently Asked Questions

1. What is the maximum surface temperature of heat tracing cable?

Our heat tracing cables reach a surface temperature of up to 150 C. For higher process temperatures we supply high-temperature grades rated up to 260 C.

2. Can heat tracing raise the medium temperature significantly?

Heat tracing cannot heat a medium from ambient to 100-200 C on its own. It maintains an existing temperature and prevents freezing or solidification. If the medium enters at about 100 C, the cable can hold that temperature.

3. Which maintains a higher temperature: detachable or non-detachable cable?

Non-detachable (MI / series) cable maintains higher temperatures - linear maximum maintain temperature 450 C, withstand 600 C. With a thermostat it holds 130 C stably.

4. What are the parameters of the 60 W/m cable in stock?

The 60 W/m cable in stock has a linear maximum maintain temperature of 205 C and withstand temperature of 260 C.

5. Can a 60 W/m cable heat an empty pipe to 150 C?

No. A 60 W/m cable cannot reach 150 C on an empty pipe; the heat loss to the environment exceeds the cable output.

6. What insulation thickness is needed to maintain 130 C?

Maintaining 130 C requires at least 80 mm of insulation. 20 mm is far too thin - the heat loss cannot be offset.

7. Which type is used for outdoor water pipe freeze protection?

Self-regulating cable is normally used: it can be cut to length on site, will not overheat if overlapped, and is available in 12 V / 24 V / 220 V versions.

8. How do I size the cable for a given pipe?

Send us pipe diameter, pipe length, maintain temperature, minimum ambient temperature and insulation thickness. We return a heat loss calculation, cable selection, circuit layout and bill of materials within 24 hours.
