OIL UK ULTRA-THERM is a superior quality, competitively priced synthetic 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.
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.
WHY ULTRA-THERM IS SUPERIOR TO MINERAL OIL BASED HEAT TRANSFER FLUIDS?
Standard heat transfer oils are based on traditional solvent refined mineral oils which have moderate thermal stability. However ULTRA-THERM is based on synthetic oils which contain high performance saturated cyclic hydrocarbons, and do not contain the aromatic molecules and polar compounds such as sulphur, nitrogen and oxygen present in mineral oils that affect thermal stability.
This difference in thermal stability is demonstrated clearly in the severe ASTM (American Society for Testing and Materials) tests below which are used by the internationally to determine oxidation and thermal stability.
THE BENEFITS OF ULTRA-THERM ARE COMPREHENSIVE :
Substantially better oxidation resistance
Superior thermal stability
Higher Viscosity Index – reduced “thinning out” at high temperatures
Considerably reduced residues at high temperatures
Better water separation characteristics
Substantially lower volatility
Excellent low temperature fluidity
Superior purity - Lower toxicity, due to virtual absence of impurities, providing enhanced health and safety
Better environmental credentials – twice as biodegradable as mineral oil based products
Reduced system corrosion
- Better performance, but less expensive than other leading competitive fluids.
OIL UK ULTRA-THERM is recommended for use in enclosed and sealed heating and cooling systems with expansion tanks in all types of industrial processes where the maximum bulk oil temperature does not exceed 325°C and the maximum oil film temperature does not exceed 345°C.
ULTRA-THERM will resist oxidation at high temperatures for substantially longer periods than products claiming similar maximum bulk temperature properties due to its inherent synthetic molecular structure, as evidenced in high stress oil industry ASTM oxidation tests. This results in longer oil life at continuous high temperatures, reduced oxidation by-products such as deposits and varnishes and enhanced system efficiency.
