Product Information

A highly efficient, non-toxic, food grade heat transfer fluid that is HT1 certified and safe for incidental food contact in food processing and pharma applications.

 

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 hydrotreated base stocks, Neobat FG Heat transfer fluid has outstanding thermal and oxidation stability allowing operation at high temperatures for extended periods. It is non[1]hazardous, non-toxic, water white and odourless.

Neobat 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 (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.

Neobat 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 into 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 Neobat 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.

Neobat 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

    Neobat 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 326˚C.

    Service Considerations

    Neobat 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 Neobat, please ask for details.

    Compatibility

    While unused Neobat® 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 Neobat FG Heat transfer fluid as a top-up to used fluids may help to increase fluid life.
