NF® heat transfer fluid is highly efficient, thermally stable and cost-effective. Completely non-toxic, it is exceptionally safe to use and is easy to dispose. Used fluid can be safely combined with spent lubricating oils and recycled locally (EPA, citation 57FR21524). The NF fluid is specified in a broad variety of applications, world wide. It is tough and durable with a proven record of success under demanding conditions, yet is easy and safe to handle.
Unlike conventional heat transfer fluids, the NF will not cause hard carbon formation on heated surfaces. Conventional heat transfer fluids, when severely overheated, will produce sooty carbon at the film layer. Much of this carbon immediately adheres to the heated surface and bakes on, forming a crust. As layer-upon-layer builds up, heat transfer and in many cases flow is impaired. Although nearly impossible to remove without scraping, sandblasting or using chlorinated solvents, the carbon can ultimately break loose, and large chunks of it can circulate through the system impeding flows and fouling components. Where fouling is extreme, heater tubing and electrical elements will stress and prematurely fail. Under similar extreme overheat conditions, the NF fluid evolves small carbon granules. These granules remain in suspension and are easily filtered out.
The NF has passed Bioassay. Rainbow trout, fresh water shrimp and Gulf shrimp were exposed to water-accommodated fractions of the NF fluid. No organisms died, and there were no ill effects. In the event of a release, you can use the same simple clean-up procedures employed for light lubricating oils. Once gathered, the NF fluid can be combined with spent lube oils and sent to the local oil recycler. There it can be converted into another useful material, preserving natural resources. The crystal-clear NF contains no chlorinated hydrocarbons, aromatics, heavy metals, or sulfur or nitrogen compounds.
The NF fluid is completely non-toxic. It is certified by the FDA and USDA, by Canadian Agriculture and Health & Welfare and by New Zealand MAF for use with food and pharmaceuticals. It also carries the USDAs H-1 incidental food contact rating and is certified kosher by the Orthodox Union (O-U), the worlds premier kosher certifying agency. Do not breathe vapor mists of any fluid (see the Material Safety Data Sheet for further information on these, and other conditions).
The NF fluid has an extraordinarily low vapor pressure less than 1/3 of an atmosphere at its maximum operating temperature of 600°F. This and the fluids exceptionally low pressure drop permit the designer considerable latitude in the choice of lower-cost equipment.
The lower a heat transfer fluids viscosity, the less energy will be required to pump it through the system. NFs viscosity is among the lowest of available high temperature heat transfer fluids. This means that less horsepower is needed for a given duty, and that a smaller pump and motor can be specified. And lower power consumption continues to produce savings year after year.
The NF fluid is manufactured from natural feedstocks and offers the same superb metal-coating and lubricating properties as the finest natural oils. However, any water allowed to stand in piping, components or especially expansion tanks of thermal oil systems can cause severe corrosion. Because the NF is immiscible with water (and is also slightly less dense), any water can be easily drained from the systems low points, or the components drain valves. Crack the low-point valve and allow fluid to drain into a beaker or clear water glass. If you see a phase separation (one liquid "floating" on top of the other), continue to drain until no separation is observed.
Containers of heat transfer fluid should be kept in non-hazardous dry areas only. Until ready for use, the containers tamper-evident safety seals must remain intact. Liquids should not be allowed to pool on the tops of steel drums. In the afternoon and evening when temperatures decrease, the heat transfer fluid will cool and contract slightly. A partial vacuum is created in the drum, and, if the bungs O-ring seal is not perfect, liquid standing on the top of the drum can be drawn through, contaminating the fluid. If drums must be temporarily stored outside, store them on their sides.
For optimal performance of both your system and its heat transfer fluid, we strongly suggest that piping, valves and other components be thoroughly cleaned before installation. Mill scale, weld spatter and slag, quench oils, protective lacquer and varnish coatings, and dust and dirt can act to degrade the fluid, and can damage pumps and valves. And lodging in restrictions, these contaminants can easily create the same low flow conditions that cause premature failure of systems and fluid.
Immediately after completing installation of the system, we suggest you purge with inert gas. Such purging can eliminate air and water vapor, and can substantially reduce corrosion. And while purging, you can leak test the system using simple soap-bubble detection methods. Finally, when you charge the system, any gas that becomes dissolved in the fluid will be inert, and fluid oxidation at start-up will be almost nil.
When charging the system, we suggest you fill from the bottom (a point near pump suction) using a small positive displacement pump not the system pump. Charging from the systems low point can help reduce trapped air in the system, which will substantially reduce the entrainment of gas bubbles and resultant pump cavitation.
Because Paratherm heat transfer fluids are produced from natural U.S. feedstocks, they are exceptionally safe to use. Easy to dispose, used Paratherm fluids can be safely combined with spent lubricating oils and recycled locally (EPA, citation 57FR21524). Paratherm strongly encourages recycling of used heat transfer fluid to conserve natural resources and to minimize the problem of liquid waste in landfills.
Overheating, oxidation and contamination of your heat transfer fluid can significantly reduce its ability to perform. Product quality will suffer, and in severe cases considerable damage to your thermal oil system can result. Periodic analysis of your fluid can allow you to detect problems in the early stages and achieve substantial savings.
We thoroughly test each batch of heat transfer fluid to ensure absolute conformance to tight product specifications. Each shipment is traceable to its master batch, with test results archived at Paratherm.
Our technical expertise is available to you in the conceptual stage, during planning and design, and through system construction, start-up and operation. We want to work closely with you in the recommendation of proven thermal fluid systems, components, supplies and procedures. We also advise on system cleaning and repair, should these become necessary. And if your application calls for fluids that we are unable to provide, Paratherm will assist you with the names and phone numbers of competitors engineers that can help.
Paratherm has available technical data sheets covering a variety of thermal fluid and system topics including fire prevention, system performance tracking, recommended components, draining, flushing and charging and fluid analysis, among others. Wed be pleased to forward these to you upon request.
