Made with DOW PuraGuard™ Propylene Glycol USP/EP, a pharmaceutical grade of monopropylene glycol with specially formulated packages of food grade industrial inhibitors that help prevent corrosion.
Regular DOWFROST™ inhibited propylene glycol (PG) DOWFROST™ is comprised of about 96% PG and 4% corrosion inhibitors. All ingredients are food safe, that is to say they are classified as GRAS (generally regarded as safe) by FDA and are approved as direct food additives. DOWFROST™ is the product of choice for the food processing industry. It is undyed and has water white appearance. DOWFROST™ offers effective heat transfer over a slightly narrower temperature range than DOWTHERM™ fluids: from 0 F to 250 F. The higher minimum recommended temperature for PG based fluids is because PG has higher viscosity and is more difficult to pump at low temperature. DOWFROST™ inhibited PG can provide freeze protection down to -60 F. DOWFROST™ is offered is various concentrations and package sizes. Color: Clear Propylene glycol-based fluid Propylene glycol-based fluid (96%) Water white Made with DOW PuraGuard™ Propylene Glycol USP/EP Low toxicity - complies with FDA and USDA regulations Operating range: 0 to 250° F for heat transfer 60° F for burst protection Heating, Ventilation & Air Conditioning (HVAC) Chill water & hydronic heating loops Geothermal (ground source heat pumps) Snow melt & Turf heating systems Solar hot water heating Fire water sprinkler systems Food processing Chilling of dairy products & beverages Beer & wine (fermentation cooling) Freezing of concentrated juices, meats, poultry & fish Refrigeration Ice skating rinks Cold storage, refrigerated warehouses & supermarkets (secondary loop) Thermal Energy Storage (TES)
A 20% propylene glycol solution that is intended for geothermal heat pump systems.
A ready to use solution that contains specially designed corrosion inhibitors that meet ASTM D1384 corrosion protection requirements. The low glycol content provides lower viscosity and higher heat transfer efficiency. This fluid has a freezing point of 18.5°F. Recommended Use Temperature Range: -5ºC (23ºF) to 100ºC (212ºF) Typical Properties of DOWFROST GEO 20 Fluid: Composition (% by volume) Propylene Glycol – 20 Performance Additive + Water – 80 Color – Yellow to Green Specific Gravity – 1.017 - 1.027 25 / 25ºC (77 / 77 º F) pH of Solution – 9.5 - 10.5 Reserve Alkalinity (min.) – 3.5 ml Formulated for geothermal systems Intended for use in Geothermal heating and cooling systems
or beverage application.
A formulation of propylene glycol and a specially designed package of industrial corrosion inhibitors. The fluid is dyed fluorescent yellow to aid in leak detection. Not approved by the USDA or FDA for food use, and is not suitable for food...
DOWFROST™ HD inhibited propylene glycol (PG) is comprised of about 94% PG and 6% corrosion inhibitors. The lower PG content in DOWROST™ HD allows for additional corrosion inhibitors including some which are not approved by FDA as direct food additives. These additional components do not compromise toxicity fluid and provide an enhanced level of corrosion protection which is unsurpassed in the industry. DOWFROST™ HD has a fluorescent yellow color and is capable of operating at higher temperatures than regular DOWFROST™: from 0 F to 325 F. DOWFROST™ HD is intended for low toxicity, non-food processing applications and provides freeze protection down to -60 F. Dowfrost™ HD is offered is various concentrations and package sizes. Color: Green / Yellow Propylene glycol-based fluid Propylene glycol-based fluid (94%) Fluorescent yellow Increased concentration of inhibitors Not USDA/FDA approved industrial / commercial version of DOWFROST Operating range: 0 to 325° F for heat transfer -60° F for burst protection Heating, Ventilation & Air Conditioning (HVAC) Chill water & hydronic heating loops Geothermal (ground source heat pumps) Snow melt & Turf heating systems Solar hot water heating Fire water sprinkler systems Refrigeration Ice skating rinks Cold storage, refrigerated warehouses & supermarkets (secondary loop) Thermal Energy Storage (TES)
