Propylene GlycolNon-Toxic Food-Safe

Propylene Glycol (PG), also referred to as Mono Propylene Glycol (MPG), has traditionally been selected for cooling and heating systems where a non-toxic classification is required. E.g. in food & beverage processing and where there are other environmental risk considerations - such as domestic solar thermal systems.

Propylene Glycol solutions have poorer heat transfer characteristics than other glycols and are relatively viscous at temperatures below -20C, often necessitating larger pipe-work, heat exchangers and pumps. To improve system efficiency and reduce operating costs, a DTX or Potassium Formate based heat transfer fluid is worth consideration.

  • Summary - Rating: BSuitable for food & beverage processing and other applications where a non-toxic classification is preferred. Average efficiency and relatively high cost per litre.

  • Efficiency - Rating: CAverage thermal conductivity and higher viscosity at sub-zero temperatures, results in reduced heat transfer efficiency and increased energy demands. Good Specific Heat capacity helps improve overall performance.

  • Antifreeze - Rating: BProvides protection down to -50°C but greater concentration (% volume) is required to achieve the same freeze-point protection, compared with DTX, IGE and LVF.

  • Corrosion Control - Rating: ALong-Life formulation with synergistic corrosion inhibitors to exceed BS6580 and ASTM D1384 standards. Also contains broad-spectrum biological inhibitors and polyacrylates to prevent scale precipitation.

  • Toxicity - Rating: AClassified as Non-Toxic and Food-Safe. Suitable for food & beverage processing systems and where low-toxicity is stipulated. LD50 Oral Rat >20,000mg/kg body weight.

  • Density:1.02 - 1.15 g/cm3 depending on inhibitors

  • pH:7.5 - 9.0 depending on inhibitors

  • Boiling Point:>100°C

  • Characteristics:a clear, slightly viscous liquid. It is mildly sweet to the taste and has a non-pungent but characteristic aroma.

  • Available in: 5, 10, 15, 20, 25, 205 & 1000 litre containers and bulk tankers.
