Product Overview

Made from a synthetic aromatic-hydrocarbon raw material for closed heat-transfer systems operating at up to 320 C.

Key Benefits

  • Outstanding thermal stability and structural stability; service life can exceed 60,000 hours within the stated operating range
  • Resists coking and carbon deposition and provides self-cleaning action
  • Low kinematic viscosity supports heat transfer, low pump resistance and energy savings

Applications

Petrochemical, synthetic-fiber, synthetic-resin, pharmaceutical, printing and dyeing industries.

Operating Notes

  • Initial heating: below 120 C, keep the heating rate below 10 C/h.
  • From 120 C to 140 C, heat at about 1 C/h with the auxiliary vent valve open.
  • Above 140 C, heat at 10 C/h to the required temperature, then close the auxiliary vent valve.
