Thermon MIQ Mineral Insulated Heating Cable v.2 - Manual (Page 2)

MIQ TM Mineral Insulated Heating Cable
MIQ Catalogue Reference Number . . .
A complete catalogue reference number will typically include the following components:
The following installation procedures are suggested guidelines
for the installation of a Thermon MIQ mineral insulated heat
tracing system. Refer to project specifications, if applicable.
Applications . . .
1. MIQ heating cables are used for freeze protection or tem-
perature maintenance of piping, tanks and instrumentation.
2. Heat tracing cables may be installed in ordinary (nonclassi-
fied) and hazardous (classified) locations depending on the
specific cable options and approvals.
Determine Heat loss. . .
There are several ways to determine the heat loss for pipes un-
der given set of design conditions:
• Heat loss calculation such as those detailed in IEEE
Std.515 (IEEE Standard for the Testing, Design, Installa-
tion, and Maintenance of Electrical Resistance Heat Tracing
for Industrial Applications).
• Computer-aided design programs that allow the user
to input detailed information specific to an application.
(Thermon's CompuTrace
® design and selection program
provides this and more based on the formulas presented
in IEEE Std.515).
• Heat loss charts based on selected pipe diameters, tem-
perature differentials and insulation materials.
• Please contact Thermon for additional information on pipe
and vessel heat loss.
The National Electric Code and Canadian Electrical
Code require ground-fault protection be provided
for electric heat tracing.

Notes. . .
1. The measurement in feet is standard. Metric lengths are followed by the letter “m ”.
2. If the field is blank, then the heating cable set utilizes silver braze connections.
3. If the field is blank, then the heating cable set is intended for ordinary (non-classified)
locations or D2, AEx de, or Ex de hazardous (classified) locations. If the value in the
field is “1”, then the heating cable set is intended for D1, AEx d, or Ex d hazardous
(classified) location.
