Duratherm HTO Heat Transfer Fluid
Categories: Fluid

Material Notes: Duratherm HTO is engineered for many years of service and it’s ideal for a wide range of closed to atmosphere (inertly sealed) applications including paint, rubber, paper mill calendars, board plants, roofing, textiles, laundry, refineries and asphalt production. Duratherm HTO’s uses highly refined base stocks that ensures excellent thermal stability. Its low volatility minimizes vapor pressure at elevated temperatures. Duratherm HTO contains antioxidants, metal deactivators and corrosion inhibitors to enhance the fluid’s longevity. Duratherm HTO is environmentally friendly, non-toxic, non-hazardous and non-reportable. Duratherm HTO poses no ill effect to worker safety. Duratherm HTO can easily be disposed of with other waste oils.
