Thermal fluid systems can vary widely in relation to design and efficiency, so the operating range and Max. bulk and film temperatures shown above are typical only and cannot therefore represent any form of individual system recommendation or warranty.
ULTIMATE HIGH TEMPERATURE PERFORMANCE, PLUS FOOD AND PHARMA SUITABILITY
OIL-UK THERMALTRANS FG & THERMALTRANS FGS represents cutting edge heat transfer oil technology, combining super refined high purity with a ultra-high flash points.
These new generation thermal fluids provide outstanding protection from thermal and oxidative breakdown, and are free from the impurities that hinder the performance of other thermal fluids. This provides a unique combination of superior high temperature performance with Food Grade credential, making these oils suitable for high temperature applications in industrial, pharmaceutical and food processing thermal fluid systems.
THERMALTRANS FG and THERMALTRANS FGS are fully approved by the National Sanitary Foundation (NSF) as HT1, suitable for incidental food contact. They are also FDA Title 21 CFR 178.3570 and 178.3620 “Lubricants with incidental food contact” compliant.
Use of these products enhances workplace safety, provides extra compliance with insurer requirements, whilst further enabling Hazard Analysis Critical Control Point (HACCP) principles in relation to potential contamination hot spots.

ULTRA-HIGH PERFORMANCE THERMAL FLUIDS
OIL UK ULTRA-THERM and ULTRA-THERM 100 are superior quality, competitively priced heat transfer fluid with outstanding thermal stability, enabling increased change-out intervals, improved system efficiency and reduced costs.
ULTRA-THERM delivers substantial performance benefits over standard mineral oil based products such as Shell S2 and BP Transcal N etc. and provides superior protection against the premature oxidative breakdown that reduces oil life and creates the build-up of sludge and varnish deposits which reduce heat transfer efficiency and system safety.
ULTRA-THERM 100 is suitable for systems designed to use a high viscosity grade benefits from an exceptionally high Flashpoint in excess of 260°C
In continuous high temperature international oil industry tests OIL UK ULTRA-THERM is shown to be up to three times more thermally and oxidative stable than standard mineral oil based heat transfer fluids.

HIGH PERFORMANCE THERMAL FLUID
OIL-UK THERM 32 is a high quality heat transfer fluid based on highly refined base oils blended with performance enhancing additives to provide excellent oxidation stability and resistance to thermal cracking. This is a real “workhorse” high temperature fluid that has been specially formulated to provide excellent thermal stability and to prevent the formation of deposits and varnishes which can build up over time resulting in reduced system efficiency.
This special formulation also reduces oil viscosity increase in service and enables the product to provide extended service life and reduced downtime.
OIL-UK THERM 32 exhibits high specific heat and thermal conductivity for rapid heat dissipation, and flows rapidly at low temperatures ensuring excellent start-up circulation. It also exhibits low vapour pressures at elevated temperatures, greatly reducing evaporation, vapour lock and cavitation.

HIGH VISCOSITY THERMAL FLUID
OIL UK THERMALFLUID D is a high viscosity heat transfer fluid based on specially selected highly refined mineral oils that provide superior performance in indirect closed heat transfer systems. This product is also non-corrosive and non-toxic, and is suitable for customers requiring a Shell Thermia D type product.
Thermalfluid D has been specially formulated to provide excellent thermal stability and to prevent the formation of deposits and varnishes which can build up over time resulting in reduced system efficiency.
Thermalfluid D exhibits high specific heat and thermal conductivity for rapid heat dissipation, and flows rapidly at low temperatures ensuring excellent start-up circulation. It also exhibits low vapour pressures at elevated temperatures, greatly reducing evaporation, vapour lock and cavitation.

The system should be thoroughly tested for leaks prior to filling with fluid and commissioning. If the system is suspected of being contaminated with excess levels of debris which would not normally be being picked up by a suitable strainer, or if it has previously been filled with a fluid which is considered to be at the end of its working life, consideration should be given to flushing it with an OIL-UK Flushing Oil or OIL-UK Flushing Additive Concentrate to remove varnishes and oxidised materials. Water must not be used. If flushing is to be applied, the system should thereafter be drained completely and filled with new OIL-UK Therm 32 heat transfer fluid up to a level in the expansion chamber which represents 30-45% of the level expected at operating temperature. All air must be evacuated from the system prior to the temperature reaching operating level. Mineral oil expands when heated so an expansion chamber must be incorporated in the system and a suitable low level alarm switch is strongly recommended to be fitted on the expansion tank. This is the only location where the oil is likely to be in contact with the atmosphere. Precautions must be taken to ensure that exposure to air is minimised, especially if the temperature of the oil in the expansion chamber is likely to exceed 50°C. A floating cover can be used or the oil can be blanketed with inert gas.
LOW TEMPERATURE THERMAL FLUID
OIL-UK THERM LT is a high quality mineral oil based thermal fluid, for use primarily in non-pressurised closed liquid-phase heating systems that incorporate both heating and cooling branches. This product has excellent resistance to thermal cracking and chemical oxidation and is non-corrosive and non-toxic. OIL-UK Therm LT has a very low pour point, and therefore provides excellent circulation at low temperatures.
