Specialized Propylene Glycol, Ethylene Glycol, and BioGlycol for Heating and Cooling Systems

                                                                                         

If you need a heat transfer fluid for your heating or cooling system, you may want to consider a propylene glycol heat transfer fluid. These fluids can also be used in HVAC systems, thermal energy storage systems, hydronic heating, solar systems, and ground source heat pumps.

Choose an inhibited Propylene Glycol
Avoid uninhibited glycols if corrosion or rust protection is a long-term concern. Uninhibited glycols can be exposed to heat and/or oxygen. This exposure will breakdown the glycol and form acids that will lower the
pH and attack the metals in your system.

Inhibitors can be added to propylene glycol to protect your system by coating the metal with a microscopic layer of film so that the glycol mixture does not come in contact with the metal, preventing corrosion.

Types of Propylene Glycol Available for Heating and Cooling Systems

Dynalene PG—Inhibited Propylene glycol is a clear, non-toxic fluid that the FDA considers “generally recognized as safe”. This inhibited propylene glycol is non-toxic, and offers superior corrosion protection. It has a low oral toxicity which allows it to be used in applications where incidental contact with food or beverage products may occur. The substance is made up of Propylene Glycol : 94.5% and Inhibitors : 5.5%. It has a reserve alkalinity (min.) of 10.6 ml and a flash point (closed cup) of 102°C (215°F), with
pH of 9.0 — 9.6. The recommended temperature ranges for a closed system are -29°C (-20°F) to 121°C (250°F).

The Prime Applications Benefits of using Dynalene PG are:
• HVAC/R
• Solar applications
• Thermal Energy Storage
• Processing Cooling/Heating
• Line Heaters
• Snow Melting
• Refrigeration Systems
• Plastic Extrusion
• Pre-mix solutions
• Custom blends
• Ability to be re-inhibited
• Proven performance
• Available throughout North America
• Cost effective
• Equivalent chemistry

Dynalene BioGlycol—Inhibited Glycol that is a non-toxic corn derived glycol, unlike propylene and ethylene which are derived from petro-based fluids. Dynalene BioGlycol®, “Nature’s First Glycol®”, is an excellent choice for today’s environmentally conscious customer. It offers greater thermal stability while possessing similar or better physical properties compared to ethylene and propylene glycol fluids. In addition, it performs better than propylene glycol, while giving it’s users an environmentally safer product than ethylene glycol fluids. This fluid is an exclusive blend using Susterra™* propanediol, manufactured by DuPont Tate & Lyle and our highly effective inhibitor package. Dynalene BioGlycol® provides a 30% lower viscosity at low
temperatures, compared to traditional petroleum derived propylene glycol.
