Propylene Glycol

This is a heating‑cooling solution made from USP pharmaceutical-food grade propylene glycol.

Propylene glycol is odorless, colorless, clear, low‑volatile, viscous, neutral, and hygroscopic. The product is mixed with water and lower alcohols, ketones, and esters in any ratio. USP propylene glycol has similar effects to ethanol and works as a bactericide. It inhibits microbial growth in solutions. It meets USP and European pharmaceutical purity standards. Propylene glycol is suitable for cosmetics and hygiene, pharmacy, food, tobacco, agro, and other industries. It is used as a heat transfer fluid, antifreeze, coolant, etc.

Only distilled or demineralized water should be used for dilution.

Propylene glycol is an excellent heat transfer fluid for heating, cooling, and solar systems

Using propylene glycol as a heat transfer fluid protects homes, people, and animals from disasters like earthquakes, fires, system breakdowns, or operational deviations. Due to its ability to lower the freezing point and its low corrosiveness, it extends the lifespan of heating systems. In setups like country hotels, guesthouses, and holiday homes with closed heating systems, a reliable, eco‑clean heat transfer fluid is needed that withstands high energy loads and has high thermal capacity, conductivity, anticorrosion, longevity, crystallization‑resistance, and good lubricating properties. Propylene glycol‑water solutions provide these.

 Diluted 1:1, freezing point is ‑37.5 °C

In heating systems it is recommended to dilute at a 1:2 ratio (1 l concentrate + 2 l water). This ratio is suitable since circulation pumps can more easily move the fluid, reducing strain and protecting the pumps. Use well water or borehole water; city water isn't recommended due to chemical additives that may cause scaling. At 1:2 dilution, freezing point is approx. ‑16.1…‑18 °C, volume fraction ~30%. Mix liquids thoroughly in a container before adding to the system—do not mix directly in the system.
