Texatherm is a proven performance industrial heat transfer oil formulated for use in both closed and open heat transfer systems with forced circulation.

Proven performance industrial heat transfer oil

Texatherm is formulated with highly refined, thermally stable paraffinic petroleum oil and offers clean and energy efficient system operation.

Benefits

  • Offers energy efficient heat transfer performance, helping keep costs down
  • Thermal stability promotes long-life keep-clean system performance and assists with sludge and coke deposit resistance
  • Low temperature fluidity aids cold system start-up, rapid fluid circulation and operation
  • Low vapour pressure at elevated temperatures helps minimise evaporation, vapour lock and pump cavitation
  • Promotes efficient operation at lower system pressures, avoiding the need for expensive high pressure piping and heat exchangers

Applications

  • May be used in heat transfer systems in industrial drying applications, rubber and plastics manufacture, heating of asphalt and fuel oil tanks, factory heating, manufacture of soap, resin, glue, dyes, paints and grease, wood laminate, fibre board and veneer manufacture, agricultural heating and drying, and chemical, petroleum and wax processing
  • Suitable for use in open systems operating at temperatures up to +200°C
  • Suitable for use in closed systems (sealed with cold oil or inert gas) operating at bulk oil temperatures up to +320°C
  • For long, trouble-free service in closed systems, the maximum film temperature on heater surfaces should be limited to +340°C
  • Systems must have forced heat transfer fluid circulation
  • While unused Texatherm is compatible with most organic heat transfer oils, prior laboratory testing is recommended before the product is added as a top-up to a system containing a competitive used oil. Adding Texatherm as make up to severely used oil, especially aromatic types, may precipitate suspended sludge

Approvals

  • DIN 51522 -Q
  • ISO 6743-12 Family Q
