CASSIDA FM HEAT TRANSFER FLUID is designed for closed circuit and pressureless heat transfer systems. It is based on a careful blend of highly refined oils and additives chosen for their ability to meet the stringent requirements of the food industry. Certifed by NSF for ISO 21469 and registered by NSF (Class HT1) for use where there is potential for incidental food contact. Produced according to FLT Quality Standards, in facilities where HACCP audit and Good Manufacturing Practice have been implemented and form part of the quality and hygiene management systems ISO 9001 and ISO 21469.




Heat transfer systems with a bulk oil temperature range of approximately -10 °C to max. +325 °C where the surface temperature of the heating elements (oil film temperature) should not exceed +340 °C


General Instructions


Care should be taken to ensure suffi cient flow rate to avoid even a temporary overheating of the CASSIDA FM HEAT TRANSFER FLUID 32. Reynolds-Number should be >10,000 (ten thousand). This is most important during start up and shut down of the heating system. The surface temperature of the heating elements (film temperature) should not exceed +340 °C. For physical parameters of the oil necessary for the calculation of the heat transfer coefficient in the system, such as density, specific heat and coefficient of thermal conductivity please contact your local partner. To ensure maximum lifetime it is recommended to monitor the oil periodically. For cleaning and flushing of contaminated heat transfer systems the use of FM FLUSHING FLUID 32 is recommended.


Seal and Paint Compatibility


Compatible with the elastomers, gaskets, seals and paints normally used in food machinery lubrication systems.


Handling and Storage


All food grade lubricants should be stored separately from other lubricants, chemical substances and foodstuffs and out of direct sunlight or other heat sources. Store between 0 °C and +40 °C. Provided that the product has been stored under these conditions we recommend to use the product within 5 years from the date of manufacture. Upon opening a pack, the product must be used within 2 years (or within 5 years of date of manufacture, whichever is the sooner).
