Frostguard
is a self-limiting heat tracer providing
the ultimate solution for frost protection
of all types of pipelines and vessels- Evolved
from a family of tracers developed for the
process industry. Frostguard is able to offer
a pedigree that is second to none.
Constructed from a high density self-limiting
core, Frostguard demonstrates the
ability to adjust its power output according to surface temperature; thus
reducing output as the temperature
increases and accordingly increasing
output as the
surface temperature decreases, Frostguard can therefore provide power where
required, preventing unnecessary
overheating of the pipe or vessel
and its contents.
The twin bus wire circuit,
not unlike that of an electric supply cable,
enables Frostguard to be cut at any point along
its length, thus ensuring flexibility of design
and ease of installation, eliminating the need
to ascertain the exact tracer length prior
to site visit.
Where extra mechanical protection is required or where earth continuity is of
utmost importance, Frostguard is available with a stainless steel overbraid;
and if it is to be installed in a chemically aggressive environment then Frostguard
can be supplied with a polymer oversheath.
