Ravenna, OH
SL – Self-Regulating Low Temperature
Maintenance Bundles
General
Parfex TemptraceTM tubing is thermally insulated with
a non-hygroscopic inorganic fberglass material and
protected with a fexible black fame-resistant PVC
jacket.
Parfex standard TemptraceTM is thermally insulated
for transfer of fuids or gases up to 185°F (85°C)
while maintaining an outer jacket surface temperature
of 140°F (60°C), meeting NEC Personnel Protection
Code 427.12.
SL-TemptraceTM is designed to provide freeze
protection and low-temperature maintenance for
gases, liquids or other viscous materials. With
outdoor temperatures of -40°F (-40°C),
SL-TemptraceTM will maintain a process fuid or gas at
40°F (4.4°C).
SL- TemptraceTM can maintain process tube
temperatures up to 140°F (60°C), depending upon
ambient conditions.
Heating Cables
Cables are available in 120V and 208-277 volt, with
Heat outputs of 3, 5, 8 and 10 watt/ft.
Parfex standard SL designs all come with an internal
tinned copper braid on heating cable for grounding
purpose and a TPR jacket over the heating cable to
provide additional protection against many inorganic
chemical solutions.
Common Tube Materials and Sizes
TemptraceTM is readily available in 1/4”, 3/8” and 1/2”
sizes as well as metric sizes. (6 mm, 8mm, 10mm
and 12mm) The most common stock alloys are
copper type #122 DHP seamless ASTM B68, B75, as
well as seamless and welded stainless steel tubing
316/316L ASTM A269. Many other alloys, ASTM
standards and sizes are available upon request.
(See Technical Data Section)
Testing
All TemptraceTM products are pressure tested prior
to shipment. Third party testing and witnessing is
available upon request, including DNV, ABS and
Lloyd’s Register. Contact factory for complete details.
Jacketing Materials
Black UV resistant FR-PVC is our standard material,
however other jacketing materials are available upon
request, including non-halogenated FR-TPE and
Urethanes. (See Technical Data Section)
NOTE: It is absolutely necessary to seal the ends against
contamination from moisture and/or corrosive liquids. Parker
Hannifn cannot assume any liability for product damage caused by
moisture from unsealed ends.
Maintain Temperatures up to 150°F (65°C) and withstands
