Peter Huber Thermofluid SilOil M20.195/235.20 (5 Ltr)

Peter Huber SilOil M20.195/235.20 is a high-performance silicone-based heat transfer fluid specifically engineered for demanding laboratory and industrial thermoregulation. This low-viscosity fluid is optimized for use in both open and closed systems, providing exceptional thermal stability and efficient heat exchange. With a working temperature range of -20°C to +195°C in open systems (and up to +235°C in hydraulically sealed systems like Huber Unistats), it is an ideal choice for high-precision applications requiring reliable performance across a broad thermal spectrum. SilOil M20 is non-toxic, chemically inert, and features a high flash point, ensuring maximum safety for both the operator and the equipment.

Key Features:

• Broad Temperature Range: Versatile operation from -20°C up to +235°C, making it suitable for a wide variety of heating and cooling protocols.
• Optimized Viscosity: Features a kinematic viscosity of 20 mm²/s at 25°C, ensuring high flow rates and efficient heat transfer even at lower temperatures.
• Superior Stability: Highly resistant to thermal oxidation and coking, maintaining its thermodynamic properties even under extended use at high temperatures.
• System Protection: Non-corrosive and compatible with various materials found in laboratory thermostats, protecting pumps and internal seals from premature wear.
• Environmentally and Operationally Safe: Non-hazardous, virtually odorless, and features an impressively high flash point of >200°C (ISO 2592) for enhanced laboratory safety.
• Hygroscopic Integrity: Specifically refined to minimize moisture absorption, though proper storage in original 5-liter containers is recommended to maintain optimal performance.

Huber thermal fluids are the preferred choice for maintaining the longevity of your circulator. By utilizing SilOil M20.195/235.20, you ensure that your temperature control system operates at peak efficiency with minimal environmental impact and maximum reliability.

Frequently Asked Questions

1. Why are there two high-temperature limits (195°C and 235°C)?
The lower limit (+195°C) refers to use in open-bath systems where the fluid is in contact with air. The higher limit (+235°C) is applicable to hydraulically sealed systems (like Huber Unistats), where oxidation is prevented, allowing the fluid to reach higher temperatures safely.

2. Can I mix this with other silicone oils?
It is strongly recommended not to mix different types or brands of thermal fluids. Mixing can lead to unpredictable changes in viscosity, boiling points, and chemical stability, potentially damaging your equipment.

3. How often should I replace the SilOil M20?
Fluid life depends on the operating temperature and duration of use. If the fluid becomes discolored, develops a strong odor, or shows a significant change in viscosity, it should be replaced to ensure continued precision and safety.

4. Is SilOil M20 compatible with all laboratory materials?
SilOil is compatible with most metals and many plastics. However, it should not be used with silicone-based seals or tubing, as it will cause them to swell and fail. Use FKM (Viton) or PTFE components instead.

5. What should I do if the fluid absorbs moisture?
If used at temperatures above 100°C, any absorbed moisture will turn to steam, which can cause fluid to overflow. It is best to heat the fluid slowly to 100°C in an open system to allow any moisture to evaporate before reaching higher setpoints.
