CS – Continuous Steam Purge Bundles
for Freeze Protection
General Design
Parfex CS-Continuous Steam purge bundles
are thermally insulated with a composite layer of
fberglass that allows for continuous high-temperature
steam purge up to 1100°F (593°C) while at the same
time ensuring freeze protection during winter using
self-regulating heating cables.
Parfex CS-Continuous Steam purge bundles are
properly insulated to meet customer specifed jacket
surface temperature requirements, during the highest
steam purge conditions and maximum ambient
requested. (See How-to-Order)
CS-Continuous Steam purge bundles are designed
to provide a freeze protection temperature of 40°F
(4.4°C) at the lowest specifed ambient temperature.
Heating Cables
Cables are available in 120V and 208-277 volt, with
Heat outputs of 5, 10, 15 and 20 watt/ft.
Parfex standard CS designs come with an internal
tinned copper braid on heating cable for grounding
purpose and a Fluoropolymer jacket over the heating
cable to provide additional protection against many
harsh environments.
Continuous Steam Purge
Internal bundle tubes can be steam purged for any
duration required without effecting performance
to the heating element. The outer jacket surface
temperature can vary depending upon customer
design specifcations. (See How-to-Order)
Common Tube Materials and Sizes
Parfex CS-Continuous Steam products are readily
available in single and double tube. The most
common tube sizes requested being 3/8” and 1/2”

and standards are available.
We also have available many other sizes; including
metric sizes 6 mm, 8mm, 10mm and 12mm.
