Self regulating trace heating systems
Fastening
Select the correct fastening material:
Use polyester adhesive tape or glass cloth tape that suits the
▪
expected temperatures.
Preferably use BARTEC adhesive tapes.
▪
Never use PVC electrical tape or self-adhesive tapes containing
▪
PVC or VC.
Do not use metal wire or banding.
▪
Fasten the trace heater with the adhesive tape at intervals of at
▪
least 300 mm on plastic pipes or 900 mm on steel pipes.
NOTICE
In order to ensure good heat transmission the trace heater must
have a flat, flush fit over the whole length. If necessary, reduce
the distances between the fixing points.
Apply the pipe's insulation according to the manufacturer's in-
▪
stallation instructions.
Apply an electrical warning label every 3 m on a clearly visible
▪
place.

Trace heater routing
On fittings, valves etc. you should leave a sufficiently large trace
▪
heater loop to ensure that the equipment is easily accessible.
This way, heating circuits do not have to be cut up for mainte-
nance or replacement works.
Due to the higher heat losses from fittings, valves, flanges etc.
▪
an additional length of trace heater is required. This requirement
is specified in the project planning documents.
The following illustrations show typical types of installation.
▪
NOTICE
The bending radius of the trace heater must always be at least
25 mm (for HTSB 35 mm). Do not bend on the narrow axis.
Installation on bends:
▪
Installation of service loops on components:
