Step 5: Select the appropriate outer jacket material
BARTEC self-regulating trace heaters are available with 2 different types of outer jackets. Choose the outer jacket that suits the chemical envi-
ronment it will be exposed to. For questions regarding the chemical resistance please contact your local BARTEC distributor.

Determination of the required trace heater length
The total required trace heater length is determined by taking into account the trace heater length for piping as well as allowances for valves,
pumps, flanges, pipe supports and connection kits.
Step 6: Determine the required trace heater length for the piping:
The required trace heater length for piping corresponds to the pipe length.
→
Example
50 m of piping =
50 m of trace heater
Step 7: Determine the required allowance for connection kits:
The required trace allowance for connection kits is 0.5 m for each kit.
→
Example
▪
Heating circuit with 1 power connection kit and 1 end of line lamp
The total required allowance is calculated as follows:
total required allowance
=
no. of connection kits × 0.5
