Micocal FG-35: Food-Grade and Halal Certified Thermal Oil for Food Processing Factories 

Yes, absolutely. Micocal FG-35 is a high-purity, food-grade thermal oil specifically engineered for applications demanding strict hygiene and safety standards. It holds an official NSF HT1 registration, meaning it is certified safe for use in systems where incidental, accidental food contact could potentially occur. It complies fully with FDA regulations for food-contact lubricants.

A “halal thermal oil” certification guarantees that from the sourcing of the base oils to the blending and final packaging stages, the product never comes into contact with, nor contains, any substances deemed forbidden (haram) under Islamic law. Because industrial thermal oils are used to heat massive deep-fryers, ovens, and processing plant equipment, having a recognized Halal certification ensures full compliance for food manufacturing facilities targeting global export markets.

Yes, indirect liquid-phase heating is precisely what Micocal FG-35 is engineered for. It functions smoothly in closed-loop heat transfer systems operating at high temperatures without pressure build-up. It transfers heat safely and uniformly to target applications such as industrial fryers, baking ovens, deodorization towers, and distillation units.

Because Micocal FG-35 carries an NSF HT1 registration for incidental food contact, a minute trace leakage will not pose a critical health hazard or violate immediate safety compliance codes like a standard mineral oil would. However, HT1 regulations stipulate a strict maximum concentration allowance (typically 10 ppm) in food products. If a major crack in a heat exchanger or heating coil occurs, production must be halted, and contaminated food batches must be discarded as per food safety protocol, but the risk of systemic toxic contamination is minimized.

he operational lifespan depends heavily on your system’s operating temperature, thermal design, and maintenance practices (such as utilizing a proper Nitrogen blanketing system to prevent oxidation). Under optimal closed-loop conditions up to its maximum recommended bulk temperature 325 °C, Micocal FG-35 can deliver a long service life of several years. Regular fluid monitoring ensures it remains clear of heavy thermal cracking or oxidation.

We strongly advise against mixing Micocal FG-35 with other thermal oils without prior consultation. Blending different brands or fluid chemistries, even if they are both rated as food-grade, can destabilize the fluid, degrade thermal efficiency, speed up oxidation, or create chemical residues that lower the fluid’s flash point. For optimal performance and safety, please contact us for in-depth recommended steps.

Yes. We don’t just supply the fluid, we provide comprehensive lifecycle technical support. We offer professional oil analysis services to track changes in viscosity, flash point, total acid number (TAN), and carbon residue. This data helps you predict the remaining lifetime of the oil, maintain maximum system safety, and schedule fluid replacement during planned shutdowns rather than facing unexpected downtime.

To accommodate different factory setups and top-up scales, Micocal FG-35 is available in 200-liter standard steel drums, 1,000-liter Intermediate Bulk Containers (IBCs), and via bulk road tankers for high-volume initial system fills.
