Heat Transfer Fluids

Select the fluid that matches your specific operating range. Using a fluid outside its specified range can cause freezing at low ends or hazardous flashpoints/fuming at high ends.

Key Functional Benefits:

• Extended Life Cycles: Synthetic and silicone-based fluids are designed to resist "sludging" and carbonization, keeping your circulator’s heating elements and cooling coils clean.
• Corrosion Protection: The THERMO200 solution and Nalco additives protect the metallic components of your bath from pitting and oxidation, especially in water-based systems.
• Broadest Thermal Spectrum: From the Sil 100 for cryogenic applications to the Sil 300 for high-heat oil baths, these fluids cover a combined range of 375°C.
• Safety First: Formulated with high flash points relative to their operating temperatures to ensure a safe laboratory environment during high-heat runs.

Maintenance & Safety Insights:

• Fluid Expansion: Remember that heat transfer oils expand when heated. When filling a bath that will be operated at high temperatures, do not fill to the maximum line while cold to avoid overflow.
• Water-Based Systems: For temperatures between 5°C and 95°C, always use the Algaecide & Corrosion Inhibitor Kit to prevent biological growth and scale buildup that can clog internal pumps.
• Ventilation: When operating at the upper limits of silicone oils (above 150°C), ensure the bath is used in a well-ventilated area or under a fume hood to manage potential vapors.
