FP Foundation Heating
Thermon FP parallel resistance constant watt heating cables
are designed to provide frostheave protection of cryogenic
storage vessels. With cut-to-length parallel circuitry, FP
cables can be field fabricated, eliminating the need for
specific circuit lengths to be provided for the application.
FP cable construction, with its unique fiberglass overlay,
provides the needed cyclic reliability for foundation heating
not found in other cables of this type. The fluoropolymer
overjacket provides corrosion resistance, durability for
installation in conduit, and lowers the friction factor for
Because FP cables are not subject to the inrush current
associated with self-regulating heating cables, the need for
oversizing power distribution equipment is eliminated.
FP cables are approved for use in ordinary (nonclassified)
areas, hazardous (classified) areas and Categories 2 and 3
ATEX classified areas.
