Heat Transfer Fluid

A heat transfer fluid is a liquid or gas used to transport heat from one point to another. It is found in domestic applications, such as heating network installations, refrigerators, air conditioners, and car engines. Water and oil are the most common heat transfer fluids. However, to deal with frost, corrosion, and bacteria, it is recommended to use a special ready-to-use fluid. We offer two types of liquids: MPG (monopropylene glycol) fluids, which are non-toxic, and MEG (monoethylene glycol) fluids, which are hazardous to humans and the environment. Industrial users use heat transfer fluids for various applications: as coolant in nuclear power plants, in solar panels, and for fermentation tanks... Find all our products on this page.

The heat transfer fluid commonly used in solar panels is the THERMOLIQUID SOLAIRE MPG. It is available in a concentrated version that must be diluted to achieve the desired freezing point, or in a ready-to-use version with a defined freezing point. This product contains anti-corrosion additives to protect circuits and extend their service life. Find our heat transfer fluids on this page.

TheANTIGEL MPG Concentré is highly recommended for lowering the temperature of fermentation tanks, for breweries or during the winemaking process. Unlike MEG, MPG liquid is not toxic to humans. In the event of a cooling circuit leak, it will have no impact on health. MPG holds the approval of the Direction Générale de la Santé for cooling applications. For more information, contact our technicians.

The base of these two heat transfer fluids is the same: Mono Propylene Glycol. The difference is that the antifreeze version is supplemented with anti-corrosion products. These protect the cooling circuits from corrosion and thus extend the service life of the fluid. They therefore help limit consumption. Manufacturers use the MPG antifreeze product for industrial refrigeration, sprinklers, solar panels, and external air conditioning batteries. MPG as a raw material is used in the composition of chemical products. Find our products on this page.

These two heat-transfer fluids have very similar thermal characteristics: they have excellent heat conductivity and very good thermal inertia. It is essentially their toxicity that differentiates them. MPG is a non-toxic product, and even food-grade in certain versions. MEG is dangerous to humans and the environment. Their other difference is their viscosity at low temperatures. MEG is much more fluid; it can be used at very low temperatures, down to -40°C, whereas MPG becomes thick at such temperatures.
