Therminol SP Heat Transfer Fluid

Product description

Therminol SP is a synthetic heat transfer fluid used in moderate-temperature applications. Therminol SP fluid is designed for use in nonpressurized/low-pressure, indirect heating systems. It delivers efficient, dependable, uniform process heat with no need for high pressures.

Performance Benefits

  • Long Life—You will get years of reliable, cost-effective performance, even when operating your system continuously at 300°C (570°F). This means you do not have to overspecify your fluid.
  • Excellent resistance to fouling— Because Therminol SP is a synthetic fluid, it resists the effects of oxidation 10 times better than mineral oils, meaning less oxidation and solids formation. For systems without nitrogen inerting, the performance advantages are significant.
  • Excellent Low Temperature Pumpability—Therminol SP is still pumpable at –28°C (–18°F), compared to some mineral oils that will not pump at temperatures below –7°C (20°F). With Therminol SP, your heat transfer fluid system can start up quickly and easily.
