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
