Product Description:

ORI-TECH Heat Transfer Oil formulated with highly-refined paraffinic base oil and special additive that produces a very stable product with high viscosity index. Due to this, the viscosity is maintained without suffering any variations during the heat transfer process.
Heat Transfer Oils are recommended for use in heat transfer systems where fuel oil, gas, or electricity is used to heat a fluid, which then transfers the heat to the point of application.
Specially indicated for heat transfer in closed circulation system that is at limit layer temperature up to 320 C

  •   Helps ensure long oil life through outstanding thermal and oxidation stability which helps prevent sludge or deposit formation inside piping.
  •   Help prevent rusting or corrosive problems in circulating oil system.
  •   Outstanding thermal stability helps assure minimal thermal cracking at high temperatures or in repeated cycling from low to high temperatures.
  •   Excellent stability helps assure minimal oxidation and helps prevent sludge or deposit formation inside piping.
