A Highly efficient, non-toxic, food grade heat transfer fluid
PRODUCT DESCRIPTION
A highly efficient, non-toxic, food grade heat transfer fluid that is safe for incidental food contact in food and
pharmaceutical processing plants.
Made from severely hydro treated base stocks, SYF 990-THERMOPLUS FG Heat transfer fluid has outstanding
thermal and oxidation stability allowing operation at high temperatures for extended periods. It is
nonhazardous ,non-toxic, water white and odorless.
SYF 990-THERMOPLUS FG heat transfer fluid complies with US FDA regulations 21 CFR 178.3620(b)
concerning non-food articles intended for use in contact with food. And, certified by the NSF International as
HT1 lubricants z(incidental food contact), for use in food and pharmaceutical plants and meets DIN 51522-Q
standard.
It is NOT approved for use as a direct food additive SYF 990-THERMOPLUS FG Heat transfer fluid is also fouling resistant. All organic heat transfer fluids undergo
thermal degradation over time and conventional synthetic fluids or low-quality oils will form soft sludge that
eventually coats all system surfaces and can harden in to coke. Because the coating acts as an insulator, heat
transfer rates are reduced resulting in longer heat up time, lower production rates, change in control
response and ,in extreme cases, burnout of heater tubes or electrical elements With SYF 990-THERMOPLUS FG Heat transfer fluid, these problems disappear. As it degrades, it produces small
carbon particles that do not stick to system surfaces, but remain suspended and are easily drained off or
filtered out. Heat transfer surfaces are left clean, meaning system performance remains constant SYF 990-THERMOPLUS FG Heat transfer fluid provides excellent heat transmission and efficiency at the relevant
operating temperatures . This ensures high heat transfer rates requiring limited pumping energy. It also has a
low vapour pressure, greatly reducing evaporation and cavitation, eliminating the need for high pressure piping
and equipment. Used fluid may be disposed of through several environmentally acceptable methods, such as used oil recycling or
heavy fuels burning. Talk to us about our used oil reprocessing services.
NOTE: When draining hot fluid after flushing, normal safety precautions should be taken to prevent burns and
the risk of fire.
APPLICATIONS
SYF 990-THERMOPLUS FG Heat transfer fluid is recommended for use in non-pressurized ,indirectly
heated, closed loop, liquid phase heat transfer systems used in food processing operations at temperatures up to
325 C (618 F).
SERVICE CONSIDERATIONS
SYF 990-THERMOPLUS FG Heat transfer fluid provides excellent service under normal operating conditions up
to the recommended temperatures . However, the fluid life will depend upon system design and operational
practice.
Correct fluid handling may help to sustain a life-span for this oil. Handling considerations include:
Air bubbles in the circulation system will cause cavitation and fast ageing of the fluid. For this reason, gas
bubbles need to escape into the expansion tank or need to be vented through vent/bleed valves
Ageing due to oxidation can be catalytically influenced by materials, such as water, dust, rust, and other fouling.
Hence, it is required that in new systems all fabrication debris is removed before filling
Before refilling an existing system, a complete draining of the old fluid is required. Complete draining from all
system low points is required and if complete draining is not possible at least one full charge of fresh heat
transfer fluid should be used to flush the system. Water based cleaners must be completely rinsed with fresh
water. Residual water should be removed by draining and then, purging with hot, dry nitrogen. Boiling off all
residual water in the expansion tank is not recommended since it will cause fluid degradation
During the start-ups, thermal shocking from accelerated temperature increases needs to be avoided; and
Always use fresh fluid to top off system. Fluid burped out the vent or collected in drip pans should be
discarded.
An analytical routine check of the heat transfer medium, while it is hot and circulating, should be part of
the routine maintenance plan. This check should be carried out at least once a year ,preferably three to four
times a year. Testing can be carried out by Global Heat Transfer- via the Petrelplus lifecycle management
programme- to all users of
SYF 990-THERMOPLUS FG Heat transfer fluids. The thermal fluid parameters which are measured will allow
our experts an accurate assessment of the condition of the fluid. This way ,Petrelplus testing and
analysis programmes ensure prolonged and trouble-free operation of the fluid. Changes to the condition of the
fluid are quickly detected and managed with
COMPATIBILITY
While unused SYF 990-THERMOPLUS FG Heat transfer fluid is compatible with other NSF International HT1
accredited heat transfer fluids, for use in food and pharmaceutical plants, prior laboratory testing is
recommended before topping-up the system with this product. Adding SYF 990-THERMOPLUS FG Heat
transfer fluid as a top-up to used fluids may help to increase fluid life. Global Heat Transfer can assist with lab
testing.
HEALTH AND SAFETY
