DOWTHERM (Ethylene Glycol) DOWFROST (Propylene Glycol) You can download DowFrost HD and DowTherm SR-1 engineering specifications for closed-loop HVAC systems. Unlike water which expands when it freezes, glycol contracts when it freezes. Detailing the major developments of the last decade, the Handbook of Hydraulic Fluid Technology, Second Edition updates the original and remains the most comprehensive and authoritative book on the subject. After placing a sample of the glycol in the beaker, check the reading on the hydrometer and match it to the appropriate chart to accurately determine the Glycol to water weight percentage. Aluminum Chemical Compatibility Chart: Check the chemical compatibility of Aluminum with various chemicals, solvents, alcohols and other products.. Shop Aluminum. Unfortunately, the freeze point of propylene glycol is not as low and its volume remains stable as it freezes and therefore does not offer the burst protection of ethylene glycol. Dowfrost TM HD is a 94.0 percent propylene glycol heat transfer fluid has a specially designed package of industrial corrosion inhibitors. (%) by mass. It is incompatible with acid chlorides, acid anhydrides, chloroformates, and reducing agents. Providing quality products and outstanding service to customers in Northern Ohio & Michigan since 1927. Many times the “green” colored glycol will benefit from addition of inhibitors. NOBURST is a non-toxic* antifreeze and heat transfer fluid. Due to masking by the propylene glycol group, the carboxyl group does not dissociate in water making it difficult to crosslink even in the presence of calcium ions, and therefore PGA can be effectively used as a stabilizer for dairy products and in similar applications. On the chart Ted put up (and from what a ProChiller tech guy told me), a 35% v/v glycol mixture is supposed to be 1.037 SG or so. Product name: DOWFROST™ Heat Transfer Fluid Issue Date: 04/09/2015 Page 2 of 10 This product is a mixture. Most systems can handle short periods of slush if the viscosity remains low. Deppmann. The buffers give the glycol a wider margin of safety before it will become acidic from heating. It is hygroscopic (attracts water), has low toxicity and outstanding stability, as well as high flash and boiling points, low vapor pressure and broad solvency. endobj NIST initially published a Technical Note on this issue in Jan. 1993.

Deppmann and it’s affiliates can not be held liable for issues caused by use of the information on this page. Any type of corrosion inhibitor will require periodic replacement or supplementation. Solutions have an operating temperature range of -50° F to 250° F (-46° C to 121° C), and the glycol fluid is water white (colorless). It is only the corrosion inhibitors that are added to the glycol that protect the metal. Dow glycol-based fluids include inhibited ethylene glycol (EG) and propylene glycol (PG)-based fluids. Freeze protection would be used in HVAC systems that are subject to prolonged winter shut-down but must start-up again while the weather is still cold. 30. What is the BTUH of a chilled water system with 40% Dowtherm SR-1* solution at a 40°F temperature difference and a This broad-based book covers the three major areas of Chemical Engineering.

A chart is listed below for recommended glycol concentrations for DOWFROST™ and … However, glycol will break down to glycolic acid over time and will require changing. We recommend using ethylene or propylene glycol at 50% by volume. GEO is a clear 20% PG / inhibitor blend with an optional dye for leak detection. Temperatures above about 285°F break down the buffers in most brands of propylene glycol, with the exception of Dowfrost HD, which is rated to 325°F. 203. Freeze protection is required to prevent severe damage to the water and refrigeration systems. BTUH = 100 x 40 x 500 = 2,000,000 BTUH. Freeze protection is required in systems where fluid must be pumped at the lowest anticipated temperature. Procurement must be effectively managed to ensure availability of design functions throughout a nuclear facility's service life. DOWFROST fluid has an operating temperature range of -50°F to 250°F DOWFROST™ HD has a lower PG composition to allow for higher concentration of corrosion inhibitors for maximum protection & rust prevention.
