In addition, Glycol is also regularly used to allow low temperature operation in thermal energy storage systems, where ice is made at night and used the following day to cool the building. Ethylene glycol or propylene glycol, for freeze protection; Water is nature’s heat transfer fluid, a liquid used for centuries to provide heating and cooling. From chart above, correction factor is 1.75. Shop today! This means it has a low freezing point and has inhibitors which don’t cause the metal to rust. It freezes at 32°F and boils at 212°F. It may exist in air in the vapor form, although propylene glycol must be heated or briskly shaken to produce a vapor. Propylene glycol is a synthetic food additive that belongs to the same chemical group as alcohol. It is is a chemical found in personal care products that acts as a penetration enhancer that keeps products from melting in heat and/or freezing when it is cold. Propylene Glycol. To extend this range, other chemicals like ethylene glycol and propylene glycol are added. Prevent your pipes from freezing with pipe antifreeze from Grainger. Heat transfer fluids One substance - multiple benefits. The glycol inside our electric radiators is a ready to use propylene glycol based non-toxic heat transfer fluid with anti-freeze and anti-corrosion inhibitor functions designed for heating systems and sealed radiators. 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. Propylene Glycol is a propanediol that exists as a clear, colorless and hygroscopic liquid and consists of propane where the hydrogens at positions 1 and 2 are substituted by hydroxyl groups. zPropylene Glycol 8.62 zDipropylene Glycol 8.53 zTripropylene Glycol 8.51 Volume changes resulting from heating or cooling glycol-water solutions may be readily calculated from the data presented in the below graphs. Propylene glycol USP is approved by the Food and Drug Agency (FDA) as a drug solvent for oral, topical, and injectable formulations. Propylene glycol is used as an organic solvent and diluent in pharmaceuticals and many other industrial applications. 877.244.5525 (U.S.) If you are using propylene glycol in your solar thermal or radiant floor heating installations, this is a product you should be offering to your customers. These specially formulated industrial inhibitor packages designed to prevent corrosion are widely used for closed-loop, water-based HVAC, process heating and cooling, and food industry applications. In burst protection liquids, propylene glycol, with its inherently high boiling point, lowers vapour pressure.. Provide superior protection with 55 Gallon Drums of TRUEGARD Propylene Glycol Inhibited-Heat Transfer Fluid 50/50 from Keller-Heartt. Propylene glycol is practically odorless and tasteless. Ethylene Glycol is the most common antifreeze fluid for standard heating and cooling applications. Multiply 5' x 1.75= 8.75' corrected pressure drop for 50%PG Propylene glycol is less toxic, breaks down more rapidly and is more environmentally friendly. Keep your pipes from bursting with pipe antifreeze from Grainger. 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. 30% propylene glycol has a freeze point of 8°F but the burst point is -18°F. Propylene Glycol - USP - Kosher - Food Grade - USP - Kosher - 36 oz net wt in a 1 Quart Safety Sealed HDPE Container with resealable Cap 4.6 out of 5 stars 1,302 $18.97 $ 18 . Glycol is a mystery fluid to many in the HVAC industry, but it is an essential tool for designing many different types of HVAC systems. The FDA classifies propylene glycol as an additive that is “generally recognized as safe” for use in food – not exactly a ringing endorsement. They contain specially formulated packages of industrial inhibitors that help pre- Using a 50% propylene glycol solution. Propylene glycol (PG) and ethylene glycol (EG) are the most widely used glycols. Paying to maintain and operate a propylene glycol filled heating system is like buying insurance TWICE. According to S cholar Chemistry’s (now Ward’s Chemistry ) material safety data sheet, problems associated with liquid GP include irritation and sensitivity to the eyes, skin, and mucous membranes. But research shows it can cause a few health concerns, including: Rashes and allergic reactions. Solar Mate, HD 8005, Propylene Glycol / Solar Glycol, Heat Transfer Fluid Solar Mate HD 8005 is a premixed reversible vaporizable special propylene glycol based heat transfer fluid, for solar heating installations. contains a propylene or ethylene glycol, these values should be included. Propylene glycol is used in QEC’s district heating system because of its ability to transfer large amounts of heat. 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. Propylene glycol is clear, colorless, slightly syrupy liquid at room temperature.
