THE DIFFERENCE
Our exclusive additive package, including a proprietary dual stage anti-oxidant, ensures long trouble-free operation. Duratherm LT 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 LT is engineered to give unsurpassed levels of protection and service life.
ENVIRONMENTAL
Duratherm LT is environmentally friendly, non-toxic, non-hazardous and non-reportable. It poses no ill effect to worker safety and does not require special handling. After its long service life, Duratherm LT can easily be disposed of with other waste oils.
SYSTEM CLEANING
If your existing fluid has let you down and left you with a system full of sludge or carbon, we’ve developed a full line of heat transfer system cleaners to get your system back to like-new condition.
- Features
- Non-toxic/non-hazardous
- Runs longer, keeps systems cleaner
- Low- to high- temperature capable
- Great for batch processing
- Includes free fluid analysis and tech support
Applications & Uses
- Markets
- Applications
Duratherm LT is an oxidative and thermally stable, high performance, long lasting, environmentally friendly heat transfer fluid. Duratherm LT is engineered with a broad temperature range offering precise temperature control between -29ºC (-30˚F) and 315ºC (600˚F).
Duratherm LT is ideal for batch processing requiring heating and cooling cycles and eliminates the need for heat tracing in outdoor applications.
