Heat Transfer Fluids for Real Thermal Oil Systems
Our product range covers food-grade, mineral, and synthetic heat transfer fluids for temperatures from –115 °C to 400 °C — selected and supported by engineers with deep system experience.
Micocal FG-35
Food-Grade u0026amp; Halal-Certified Heat Transfer Fluid
Micocal FG-35 is a high-purity, food-grade mineral heat transfer fluid developed for applications where product safety, regulatory compliance, and system reliability are critical.
It is halal-certified and widely used in food, starch, oleochemical, and pharmaceutical-adjacent processes. FG-35 offers stable thermal performance, low odor, and excellent compatibility with properly designed thermal oil systems.
Micocal supports FG-35 not only as a fluid supplier, but with system expertise, oil analysis, and practical guidance for long-term, compliant operation.
Micocal Q-32-N
Cost-Effective Mineral Heat Transfer Fluid
Micocal Q-32-N is a high-quality mineral heat transfer fluid designed for standard operating temperature ranges where reliability and cost efficiency are key decision factors.
It is frequently selected for system replacements, retrofits, and budget-conscious projects where stable performance and availability matter more than extreme temperature capability.
Q-32-N provides an excellent balance between performance, availability, and price — making it a practical choice for many industrial thermal oil systems.
Micocal 660
High-Temperature Synthetic Heat Transfer Fluid
Micocal 660 is a fully synthetic heat transfer fluid designed for high-temperature operation, comparable in performance class to well-known benchmark products such as Therminol® 66.
It is suitable for demanding applications requiring thermal stability at elevated temperatures, low vapor pressure, and long service life when operated correctly.
Micocal supports you with system compatibility checks, oil condition monitoring, and operational guidance to ensure safe and efficient long-term use.
Micocal 590
Low-Temperature u0026amp; Cold-Start Optimized Fluid
Micocal 590 is a synthetic heat transfer fluid developed for applications requiring excellent low-temperature behaviour, fast cold starts, and reliable heat transfer at lower operating temperatures.
It is often evaluated as an alternative to Therminol® 59 and is well suited for processes with frequent shutdowns, outdoor installations, or cold ambient conditions.
Our team supports Micocal 590 with selection advice based on system design, operating profile, and start-up behaviour.
Additional Fluids u0026amp; Support
In addition to the products shown above, Micocal supplies a broader range of organic, synthetic, and specialty heat transfer fluids — including solutions for extreme temperature ranges and specific industry requirements.
Not Sure Which Heat Transfer Fluid Fits Your System?
Selecting the right heat transfer fluid depends on operating temperature, system design, start-up behaviour, and regulatory requirements. Our specialists support you with practical, system-focused guidance — before problems occur.
