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.
Temperature range -15°C to 325°C
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 W-PGF
Ultra-Pure, Non-Toxic Heat Transfer Fluid for Liquid Cooling & Critical Thermal Systems
Micocal W-PGF is a high-purity, pharma-grade Monopropylene Glycol (MPG) heat transfer fluid engineered for high-performance cooling loops where absolute material compatibility, human safety, and strict global certifications are non-negotiable.
Temperature range -50°C to 170°C
Formulated with premium, non-toxic Organic Acid Technology (OAT) inhibitors, Micocal W-PGF provides industry-leading corrosion protection for systems utilizing delicate multi-metal components, including copper and aluminum cold plates. It contains only FDA-approved ingredients, is registered under NSF HT1 for incidental food contact, and holds trusted Halal and Kosher certifications.
Micocal supports W-PGF with specialized dilution services (using highly deionized water), long-term fluid life-cycle monitoring, and technical advice to keep your system operating at peak thermal efficiency.
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.
Temperature range -12°C to 320°C
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.
Temperature range 0°C to 355°C
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 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.
Temperature range -40 °C to 350 ° C
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 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.
