The selection of the proper heating cable and components, best suited
for the application must be checked against the relevant product
literature, the most important product properties are summarized in
following table:
Table 1: properties of mi heating units
Please check against individual datasheet or contact Pentair Thermal
Management for further details.
The maximum cable power output is directly dependant on the
application and control method used. The actual limits of MI heating
cables in a specific application are given in Pentair Thermal Management
Engineering Software (e.g. TraceCalc Pro design software). For more
details, please contact Pentair Thermal Management.
Ensure that the heating cable voltage and temperature rating is suitable
for the application.

The hot-cold junction used in a heating unit may lead to temperature
limits below the limit of the heating cable. Contact Pentair Thermal
Management if the exposure temperature exceed values given in
the tables above for more detailed instructions how the unit can be
installed under those circumstances.
