There are two main types of glycol common to heating and cooling use: Propylene glycol (PG), and ethylene glycol (EG). Where food or potable water contact may be a concern, specify propylene glycol. Propylene glycol is practically odorless and tasteless. It is a clear, odourless, tasteless liquid that readily dissolves in water and is described in the news release as “relatively non-toxic to humans and wildlife.” What is propylene glycol? Propylene glycol should be replaced when it turns a reddish color. But, there is another member of the glycol family that fits the needs of liquid process cooling and heating systems. The addition of glycol antifreeze (such as Dowfrost HD™ propylene glycol, Dowfrost™ food grade propylene glycol or Dowtherm SR-1™ ethylene glycol) to water in hydronic heating and cooling systems, lowers the freezing point of your heat transfer fluid mixture. To extend this range, other chemicals like ethylene glycol and propylene glycol are added. Use in water chillers, refrigeration systems, thermal storage, solar systems, heating and cooling loops and radiant heating systems. Mono Propylene Glycol, commonly referred to as Propylene Glycol but also referred to as Propane-1,2-diol, MPG, PG and Food Safe Glycol. Instead solutions based on propylene glycol are commonly used. Glycol or other spent fluids evacuation from HVAC loops, geothermal loops, ice rinks, process heating and cooling systems, etc. E.g. Propylene Glycol has for many years been the go-to glycol for use in food and beverage processing systems or where there is a requirement for a non-toxic classification. E.g. This means it has a low freezing point and has inhibitors which don’t cause the metal to rust. Its chemical neutrality makes it a suitable carrier for active ingredients in vaccines, local anesthetics, vitamins, and syrups. 30% propylene glycol has a freeze point of 8°F but the burst point is -18°F. Propylene glycol is clear, colorless, slightly syrupy liquid at room temperature. propylene glycol-based fluids Solutions of DOWFROST propylene glycol-based fluids are widely used for secondary cooling and heating applications, for freeze and burst protection of pipes, and for various deicing, defrosting, and dehumidi-fying applications.
