A propylene glycol-based fluid capable of operating at higher temperatures than other propylene glycol fluids.
This fluid is low in acute oral toxicity and contains a specially formulated inhibitor package that helps prevent corrosion of materials common in HVAC construction, food and beverage processing, and other systems. Propylene glycol based fluid Improved corrosion protection for aluminum alloys Suitable for use at a minimum 20% concentration for high and low temperatures Long lifetime Low acute oral toxicity Free of nitrite, borax and CMR Available in various package sizes and blends. Suitable applications include: single fluid process heating and cooling; closed-loop, water-based heating and air conditioning systems where propylene glycol-based fluids are preferred or required; and food industry applications within temperature range.
A NSF-approved, propylene glycol-based fluid that is low in acute oral toxicity and widely used to depress freeze points in food and beverage processing and in other applications.
Dowcal™ N features a specially formulated corrosion inhibitor package and can be used for direct and indirect food additive applications. Available in various package sizes and blends. Propylene glycol based fluid Better freeze protection Better corrosion protection in hot and cold systems FDA-approved safe food additive Compatible with commonly used elastomers Long fluid life and low maintenance costs Greater cost-effectiveness Low acute oral toxicity Used to depress freeze points in food and beverage processing and in other applications
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.

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)
