Did you know there are many options to consider when selecting thermal fluids?

  1. Temperature is Everything – match your bulk temperature but also consider film temperature, heater type
  2. Controlling Oxidation – high temperature air exposure can destroy the wrong fluid quickly
  3. Maximizing Fluid Life – short-term or long-term use – invest wisely
  4. Availability is Critical – thermal fluids are often critical to production – how long can you wait for your thermal fluid to ship?
  5. Reliable Service & Support – thermal fluids are maintenance-intensive, but can your vendor help you if there are problem

Duratherm 450

Rated to 233°C (450°F), Duratherm 450 is specifically engineered for applications requiring a thermal fluid capable of efficient process heating and cooling. Economical and thermally stable, it provides precise temperature control and is proven to be an excellent alternative to costly synthetics and aromatic fluids.

  • 233°C (450°F) maximum operating temperature while cooling properties
  • Cold temperature pumpability down to -45°C (-49°F)
  • Recommended for precise control of heating and cooling cycles
  • Economical alternative to costly synthetics and aromatics
  • Long lasting and environmentally friendly
  • Uses a dual-stage anti-oxidant to resist oxidation
