Duratherm FG Heat Transfer Fluid
Duratherm FG is rated for use up to 620°F and is engineered and manufactured to comply with the demands of food grade applications.
Duratherm FG meets USDA requirements for incidental food contact ( H1) and meets the requirements of 21CFR1783570 and is NSF registered.
Ideal for any application requiring food grade rated process oils such as food processing, bottling, food packaging etc.
The Difference
Our exclusive additive package, including a proprietary dual stage anti-oxidant, ensures long trouble free operation. Duratherm also incorporates metal deactivators, a seal and gasket extender, defoaming and particle suspension agents.
Lasts Longer
In the heat transfer fluid industry cost is always a concern, however fluid longevity and resistance to harmful fouling are of equal importance.
Air contact is normally detrimental to a fluid. Oxidation can cripple your system and if left unchecked will ultimately cause catastrophic failure. Unscheduled downtime due to oil failure has a high cost and negative effect on production.
The Duratherm product line was developed with this in mind. Most other fluids fall short in their protection from oxidation and can quickly foul a system. Duratherm is engineered to give unsurpassed levels of protection and service life.
Environmental
Duratherm FG is environmentally friendly, non-toxic, non-hazardous and non-reportable. Worker health and safety is of great concern, Duratherm FG poses no ill effect to worker safety. After its long service life it can easily be disposed of with other waste oils.
System Cleaning
In our effort to truly service the heat transfer industry, we have developed 4 unique and specific heat transfer system cleaners. Ranging from preventative maintenance system cleaners to emergency downtime system revivers, we have a cleaner that fits your needs and schedule.
