Description

Eastman Therminol® XP heat transfer fluid is an extremely pure white mineral oil which provides low toxicity and reliable heat transfer at moderate temperatures. When operating temperatures prohibit the use of steam or steam is not readily available, Therminol XP can provide safe and efficient operation in heat transfer systems. Therminol XP has outstanding regulatory status for those seeking heat transfer fluids which have minimum environmental reporting requirements:

• Meets the purity specifications in U.S. Food & Drug Administration Regulation 21 CFR 172.878

• Meets the requirements of National Formulary (NF)

• Listed as a registered nonfood compound by NSF International (Category Code HT-1: Heat transfer fluids—Incidental contact)

Heat transfer fluids are intended only for indirect heating purposes. Under no circumstances should Therminol XP come into contact or in any way contaminate food, animal feed, food products, food packaging materials, food chemicals, pharmaceuticals, or any items which ultimately may be directly or indirectly ingested by humans. Any contact may contaminate these items to the extent that their destruction may be required. Carefully review the information contained in a properly prepared Safety Data Sheet prior to making a fluid decision. The recommended maximum bulk and film temperatures for Therminol XP are based on industry-standard thermal studies. Operation at or below these temperature maximums can provide long service life under most operating conditions. Actual fluid life is dependent on the total system design and operation and can vary by heat transfer fluid chemistry. As fluid ages, the formation of low- and high-boiling compounds may result. Low-boiling compounds should be vented from the system as necessary to a safe location away from personnel and sources of ignition and in compliance with applicable regulations and laws. The high-boiling compounds can be very soluble in the fluid. Significant overheating or fluid contamination will accelerate decomposition and may result in increased high boiler and solids concentrations. Excess solids can typically be filtered for removal. Eastman recommends that systems utilizing Therminol XP fluid should be blanketed with an atmosphere of inert gas to protect against the effects of fluid oxidation on its performance and life expectancy. Pressure relief device(s) should be installed where required. Therminol XP is noncorrosive to metals commonly used in the construction of heat transfer systems. While Therminol XP has a relatively high flash point, it is not classified as a fire-resistant heat transfer fluid. Consequently, the use of protective devices may be required to minimize fire risk and users of Therminol XP should check with their safety and risk management experts for specific instructions.
