DOWFROST is a propylene glycol-based fluid that contains a specially formulated package of industrial inhibitors that help prevent corrosion. Because propylene glycol fluids have low acute oral toxicity, DOWFROST is often used in applications where contact with food or beverage products could occur.
What color is DOWFROST?
fluorescent yellow color
DOWFROST™ HD has a fluorescent yellow color and can operate at higher temperatures than regular DOWFROST™. DOWFROST™ HD is suitable for use in environments between -50°F and 325°F (-45°C and 160°C). DOWFROST™ HD is intended for low toxicity, non-food processing applications and provides freeze protection down to -60 F.
What is DOWFROST?
DowFrost is an industrially inhibited propylene glycol-based heat transfer fluid. Aqueous solutions of DowFrost fluid are designed to provide freeze/burst and corrosion protection, as well as efficient heat transfer, in water-based, closed-loop heating and air-conditioning systems.
What is the difference between Dowfrost and dowtherm?
Generally, the DOWTHERM SR-1 or DOWFROST HD solution is chilled to between 20 and 26°F to make ice. A 25% solution of DOWTHERM SR-1 fluid has a freezing point below 14°F, while a similar solution of DOWFROST HD fluid has a freezing point below 16°F.
What is Dowfrost propylene glycol?
DOWFROST™ inhibited propylene glycol (PG) is a best-in-class, food-grade thermal fluid for a wide range of heat transfer applications. DOWFROST™ exhibits effective heat transfer from -50°F to 250°F (-45°C to 120°C) and can offer freeze protection or “burst protection” down to -60°F.
What is the freezing point of 30% propylene glycol?
Freezing Points of Propylene Glycol based Water Solutions
| Freezing Point | ||
|---|---|---|
| Propylene Glycol Solution (%) | by mass | 30 |
| Temperature | oF | 7 |
| oC | -14 |
What is the percentage of propylene glycol?
Final products contain 20% propylene glycol, 1.5% of dipropylene glycol, and small amounts of other polypropylene glycols. Further purification produces finished industrial grade or USP/JP/EP/BP grade propylene glycol that is typically 99.5% or greater.
Can you freeze propylene glycol?
If it doesn’t smell bad and it looks OK it’s probably fine. You can also freeze food for a *lot* longer than the 3 months the label says you can. If you’re sick, or elderly, or very young, then respect the use by date, otherwise use a smell test.
What are the properties of dowfrost?
Typical Properties 1 Brand DOWFROST 2 Fluid Base Propylene Glycol 3 Freezing Point in °F (°C) -60 (-51) *when diluted to 60% 4 Maximum Operating Temperature in °F (°C) 250 (120)
Why choose dowfrost heat transfer fluid?
A great way to prolong fluid lifetime and to lower your cost of ownership, is to use DOWFROST heat transfer fluid because it is made with the highest industry purity propylene glycol combined with long lasting, food safe, corrosion inhibitors. These values are not intended for use in preparing specifications. Error loading content.
What is dowfrost™ inhibited propylene glycol?
DOWFROST™ inhibited propylene glycol (PG) is a best-in-class, food-grade thermal fluid for a wide range of heat transfer applications. DOWFROST™ is comprised of ~96% propylene glycol and 4% corrosion inhibitors to protect and extend equipment life.
What is the yellow stuff in dowfrost HD?
DOWFROST™ HD. 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 or beverage application.
