Reducing the Propylene Glycol concentration below 25% reduces the inhibitor concentrations to a level that may not provide adequate corrosion, scale and biological protection for a system. The corrosion inhibitor protects metal surfaces from corrosion without reducing the system’s heat transfer efficiency. Metal acts as catalyst in un-inhibited glycol solution for the formation of these acids, which then chemically attacks and corrodes system. Industrial grade glycol is composed of either ethylene or propylene glycol, a corrosion inhibitor, and water. It is a broad-spectrum corrosion inhibitor that improves metal surface by absorption and making it less vulnerable to corrosion. It treats the surfaces of the metal making them less susceptible to corrosion. For example, if the freeze protection needed is -20°F then the minimum amount of propylene glycol needed is 46% by volume (47% by wt. The chosen corrosion inhibitor must be formulated for propylene glycol to protect metals from corrosion. You don’t want to feed your radiator the wrong coolant. Lastly, never use automobile anti-freeze in a non-automotive application. It is not intended to be used as an additive to food or pharmaceuticals. Engine Glycol Coolant Anti-freeze properties – Corrosion Inhibition Testing. Mono propylene glycol : Low toxicity product. In the present paper, this inhibitor package is evaluated in the different The inhibitors in CoolFlow NTP are formulated to give the best possible performance and fluid lifetime at Propylene Glycol levels between 25 and 60% v/v. Acuro's Propylene Glycol Corrosion inhibitor is a chemical additive for propylene glycol to protect your closed water-based cooling systems from corrosion. Common tap water is slightly acid that can eventually corrode metal system components. Welcome back to the second part of our article on PC water coolant chemistry! Propylene Glycol Corrosion Inhibitor. Kolkata - 700046, © 2020 Chemtex Speciality Limited   ∙   Privacy Policy   ∙  FAQs   ∙  Shipping & Returns  ∙  Terms & Conditions. THERMOFROST is a 100% Inhibited Propylene Glycol designed to provide exceptional system protection and a long fluid life. Proper human safety products such as splash goggles, lab coat, NIOSH approved gloves and boots should be worn while handling and applying chemicals. It is compatible and fully functional in glycol-water & glycol-ethanol (rectified spirit) mixtures and improves heat transferability. Read more... ProFrost-100%-Inhib & Color Option.pdf (35.36 KB), ProFrost Chiller Detail Flyer0001.pdf (564.58 KB). It buffers the organic acids formed as a result of glycol/ water oxidation, preventing further formation of acids. The incorporated propylene glycol inhibitor serves to modify metallic surfaces by absorption. Ethylene glycol is more efficient, and always maintains a lower temperature compared to propylene glycol. In most cases you should mix glycol with water. Corrosion inhibitors for ethylene glycol solutions, with particular reference to cadmium-plated and terne-plated steel. adroll_current_page = "other"; 55 gallons of ChemWorld SR1 will protect 7600 gallons of 20% glycol solution from corrosion. Haute Street Corporate Park Reactions with dissolved oxygen can lead to the formation of organic acids that attack unprotected metal surfaces. ComStar's ProFrost and Frost Free are commonly used in chillers, refrigeration systems, industrial processing systems, thermal storage, computer room cooling, solar systems, heating & cooling loops and radiant heating systems.and boilers. It modifies the metal surface by absorption, making it less susceptible to corrosion. It buffers the organic acids formed as … If you continue to use this site we will assume that you are happy with it. ChemWorld SR1 Glycol Corrosion Inhibitor. Chemtex’s Propylene Glycol Corrosion Inhibitor is a specially formulated chemical additive designed to prevent corrosion in multi-ways. In addition, water may contain minerals that may contribute to the build up of lime/scale deposits that can reduce heat transfer and clog pipes. Some car brands can only be used with antifreeze brands that contain ethylene glycol. Polypropylene glycol (PPG) was investigated as a corrosion inhibitor for typical × 60 pipeline steel in 15% HCl solution using weight loss, electrochemical impedance spectroscopy (EIS), electrochemical frequency modulation (EFM), linear polarization resistance (LPR) and potentiodynamic polarization (PDP) techniques. It modifies the metal surface by absorption, making it less susceptible to corrosion. Because glycols without a corrosion package are more corrosive than water it is strongly recommended to order glycols with the corrosion inhibitor package. ChemWorld SR1 Glycol Corrosion Inhibitor. 1 This advisory bulletin references the research of Dr. Walter Rossiter and his team of the National Bureau of Standards, now named the National Institute for Standards and Technology (NIST).
