Peter Huber Thermofluid SilOil M40.165.10 (10 Ltr)

Peter Huber SilOil M40.165.10 is a premium-grade silicone heat transfer fluid specifically formulated for low-to-medium temperature applications in laboratory and industrial thermoregulation. This high-performance fluid is characterized by its excellent thermodynamic properties and low viscosity at sub-zero temperatures, making it an ideal choice for refrigerated bath circulators and chillers. With a working temperature range of -40°C to +165°C in closed systems, it provides consistent heat transfer and exceptional stability. SilOil M40 is chemically inert, non-toxic, and environmentally friendly, ensuring long-term protection of your Huber equipment's pumps and internal components.

Key Features:

• Extended Low-Temperature Range: Engineered for precision performance down to -40°C, ensuring high fluidity and efficient cooling where standard oils may become too viscous.
• High Thermal Stability: Maintains its chemical structure and thermodynamic efficiency up to +165°C (in closed systems), preventing the formation of deposits or sludge.
• Optimized Viscosity: Features a kinematic viscosity of 10 mm²/s at 25°C, reducing the load on circulation pumps and maximizing flow rates for superior temperature homogeneity.
• Superior Equipment Protection: Non-corrosive and compatible with most metals and sealing materials used in Huber units, significantly extending the service life of the device.
• Safety and Reliability: Boasts a high flash point of >160°C and a high boiling point, providing a safe operating environment for routine laboratory tasks.
• Large Volume Supply: Provided in a 10-liter container, ideal for initial filling or complete fluid replacement in medium-sized refrigerated baths like the K12, K15, or K25 series.

Choosing the correct thermal fluid is essential for the performance of your Huber circulator. SilOil M40.165.10 is meticulously refined to ensure that your system reaches setpoints faster and maintains them with the highest degree of accuracy, all while minimizing environmental impact.

Frequently Asked Questions

1. Why is this fluid recommended for refrigerated baths?
At low temperatures, many fluids become thick (viscous), which slows down heat transfer and strains the pump. SilOil M40.165.10 is designed to stay "thin" at -40°C, allowing your chiller to work at maximum efficiency.

2. Can I use this fluid in an open-bath system?
Yes, but the maximum working temperature is typically lower in open systems to prevent oxidation and evaporation. Always refer to the specific safety data and equipment manual when using silicone oils in open vessels at high temperatures.

3. What happens if the fluid is used outside its rated temperature range?
Using the fluid below -40°C may cause the pump to overload due to high viscosity. Using it above +165°C in a closed system can lead to thermal degradation, reduced flash point, and potential damage to the circulator's heater elements.

4. Is SilOil M40 compatible with silicone tubing?
No. Silicone-based thermal fluids will dissolve or swell silicone hoses and seals. Always use high-quality EPDM, FKM (Viton), or PTFE-lined hoses when working with SilOils.

5. How should I dispose of used SilOil M40?
Silicone oils are considered industrial waste and must be disposed of according to local environmental regulations. They should never be poured down the drain. Many chemical waste services can recycle or properly incinerate silicone-based fluids.
