Fastening; Trace Heater Routing - Bartec HSB+ Design Manual

Preferably install the trace heater in the lower half of the pipe.

but not on the lowest point. This prevents mechanical damage
and allows for better heat distribution.
If you use multiple trace heaters. position them with an offset of

90°.
Mount the mounting stand and junction box preferably on top of

the workpiece, e.g. the pipe. If a different orientation of the junc-
tion box and mounting stand is necessary. there is a risk of water
collecting in the mounting stand.
Avoid water accumulation in the mounting stand!
BARTEC recommends applying the pipe insulation immediately
after installing the junction box and the mounting stand.

Fastening

Select the correct fastening material:
Use polyester adhesive tape or glass cloth tape that suits the ex-

pected 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

max. 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.

Notice Technical data subject to change without notice.
No claims for damage arising from alternations, errors or misprints shall be allowed.
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. Do not bend on the narrow axis.
Installation on bends:
