Piston Power HTO are high viscosity index, paraffinic based, premium performance oil intended for use in both open and closed heat transfer systems with forced circulation.

Applications

  • Open systems operating at temperatures up to 200C.
  • Closed systems operating at bulk oil temperaturee up to 320C.

NOTE : The maximum film temperature on the heater surface should not exceed 340C for long trouble free service in closed systems.

Performance Features

  • Good oxidation and thermal stability over a wide temperature range minimises deposit formation and thus extends oil life.
  • Low viscosity and efficient heat transfer properties enable easy circulation and efficient transfer of heat.
  • Low temperature flow characteristics allow prompt circulation.
  • Low vapour pressure at elevated temperatures minimises evaporation, vapour lock and pump cavitation.
