FAQs
Q: What is the maximum operating temperature of ARMCO synthetic heat transfer fluids?
A: Our synthetic fluids (e.g., Armcoltherm 380) can operate up to 380°C in the liquid phase and up to 400°C film temperature, maintaining exceptional thermal stability without carbonization.
Q: What is the difference between mineral and synthetic heat transfer oil?
A: Mineral oils are cost-effective for moderate temperatures up to 300°C. Synthetic fluids offer longer service life (5–10 years), higher thermal resistance up to 380°C, and superior low-temperature pumpability.
Q: Can ARMCO heat transfer fluids directly replace Therminol, Dowtherm, or Marlotherm?
A: Yes! Our Armcoltherm series offers direct drop-in replacements (e.g., Armcoltherm 380 for Therminol 66 / Dowtherm RP). They are fully miscible and require no system modifications.
Q: Do you offer NSF H1 food-grade heat transfer fluids?
A: Yes, Armcoltherm 600 is NSF H1 registered for incidental food contact, ideal for edible oil extraction, food processing, and pharmaceutical applications.
Q: What are your packaging options and Minimum Order Quantity (MOQ)?
A: Our standard MOQ is 1 drum (200L / 200kg). Packaging options include 200L Steel Drums and 1000L IBC Totes.
Q: How often should I perform thermal oil analysis?
A: We recommend testing your fluid’s flash point, viscosity, and acid value once every 12 months to prevent premature fluid degradation and system failure.
