Heat Transfer Fluids Based on Glycerin
Glycerin is a substance well known to the consumer for many applications: cosmetology, medicine, food industry, tobacco production and just in everyday life.
Just like propylene glycol, when mixed with water, glycerin forms solutions that do not freeze at low temperatures.
Considering the above, along with the family of propylene glycol-based coolants, there is a family of glycerin-based coolants - liquids with a crystallization temperature below 0°C, the main component of which is glycerin.
Like propylene glycol, glycerin is a food additive, so glycerin-based heat transfer fluids are non-toxic and can be used without environmental restrictions.
Characteristics of glycerin-based heat transfer fluids
The main disadvantage of glycerin coolants is their high viscosity due to the high viscosity of the glycerin itself. Because of this property, such coolants cannot be used at all in circuits with natural circulation. In systems with forced circulation, a powerful pump will be needed that can pump the glycerine coolant at low temperatures, when its viscosity is maximum.
However, glycerin-based coolants also have an advantage. The price of a glycerine coolant is significantly less than the price of a propylene glycol-based coolant.
Thus, a glycerin-based coolant is a compromise between the characteristics of the coolant and its relatively cheap price.
A line of heat transfer fluids based on glycerin, as well as a mixture of glycerin and propylene glycol, is produced by Stron LLC in compliance with all technical documentation standards. The quality of glycerin-based heat transfer fluids is under constant laboratory control.
