The Paratherm GLT™ heat transfer fluid is an alkylated aromatic based heat transfer fluid formulated for closed-loop liquid-phase heating systems to 550°F using fired heaters and to 575°F in waste-heat recovery systems.
Applications Include...
- Gas processing
-
Liquid terminal tank heating
- Asphalt plants
- Plastic production
Paratherm GLT Heat Transfer Fluid exhibited
almost 40% less degradation when exposed to
600°F (316°C) for 500 hours than a widely
used competitive fluid. Although very few
heaters expose the fluid to the maximum film
temperature for extended periods, this level of
stability helps insure that your system operates
trouble free during operating upsets.
Minimum startup temperature is a realistic
measure of a fluid’s low temperature capability
since 300 cps is the maximum viscosity that a
centrifugal pump can handle. Paratherm GLT
Heat Transfer Fluid has a lower minimum
start-up temperature 18°F (-8°C) than any
mineral-oil based fluids that cover a similar
temperature range.
Drums should be stored inside to prevent
water from getting into the heat transfer fluid.
If sealed drums must be left outdoors, they
should be stored on their sides. While
unopened totes are weatherproof, they should
not be stacked if left outdoors. If the fluid is to
be stored outside below its minimum
pumpable temperature, the containers should
be moved indoors to warm up before charging
the fluid into the system.
In many cases, changing fluid involves a
straightforward drain and fill. There are very
few fluids that are so incompatible that 10-15%
residue will affect the new Paratherm. If you
have any questions, contact us.
Unless required for product quality reasons,
new systems do not need to be cleaned before
Paratherm is charged. The amount of chemical
coatings, oils, and other manufacturing
residues are usually not enough to affect the
fluid life. All that is necessary is to install a Ystrainer
with a minimum 60 mesh screen up
stream of the pump to catch any metal or
welding residue. The screen can be removed
once the system has been cycled twice through
its operating temperature.
The fluid in new systems should be tested
within 9 to 12 months of start-up. New fluid in
existing systems should be tested within the
first month of operation to establish a base line
for future testing.
