ARCTIC PROTECTION 95%
Powerful Freeze and Burst Protection for Closed Systems
ARCTIC PROTECTION 95% is a premium propylene glycol-based antifreeze designed to safeguard chilled water, hydronic, and other closed systems from freezing and bursting. Its advanced formulation offers exceptional protection down to -100°F while ensuring safety and compatibility with various systems.
1 gallon size is available in 95% only, for alternative concentrations, colors, and sizes, see AP-5, 55, 275 for customization options and requirements.
Key Features and Benefits:
- Powerful Freeze Protection: Prevents freezing and bursting in extreme cold conditions.
- Highly Concentrated: AP-1 is made only in 95% concentration.
- Corrosion Inhibited: Contains a custom inhibitor package designed for broad protection.
- GRAS Ingredients: Contains generally recognized as safe (GRAS) ingredients.
- Versatile Applications: Suitable for chilled water, hydronic, and other closed systems.
- Leak Detection: Standard blue dye to easy leak detection (colors are customizable, product is blue unless specified).

For a custom blend of color or percentage please contact us for a quote, we need the following information: container size (5, 55, 275), quantity in gallons, delivery zip code and color. (blue is standard, clear, green, pink, orange, red, yellow and more are available). **Custom orders not available in 1 gallon containers.
Directions:
- Clean new or lightly corroded systems with Vapco Hydronic System Cleaner (HSC‑1, HSC‑5, HSC‑55) before adding Arctic Protection. Do not use Arctic Protection with galvanized steel.
- For extensively corroded systems, clean with an inhibited acid such as Scale Remover #1 (SR1‑1) or Tankless DeScaler (TDS‑16oz, TDS‑1). Work must be performed by an experienced technician. Complete all necessary replacements and repairs before treatment.
- Choose the protection type:
- Burst protection: Prevents bursting/mechanical damage but does not keep the solution pumpable.
- Freeze protection: Higher glycol level that prevents ice crystal formation at the lowest expected temperature, keeping the fluid pumpable.
- Application guidance: Ice storage, fire sprinkler, and intermittently run hydronic systems may use burst protection. Chilled water and lawn sprinkler systems require freeze protection.
- Using the propylene glycol chart, select the lowest expected ambient temperature, then use a temperature 5°F colder for safety. From that row, note the percentage of Arctic Protection required for your chosen protection type – Freeze or Burst.
- Calculate quantity:
- V = system volume (gal)
- C = required final glycol percentage from the chart (as a decimal, e.g., 40% = 0.40)
- S = glycol strength of the product you’re using (as a decimal, e.g., 95% = 0.95; 50% = 0.50)
- Gallons of Arctic Protection to add = (V x C) ÷ S
- Gallons of DI water to add = V – Arctic Protection to add
- For corrosion protection, maintain a minimum concentration of 35–40% Arctic Protection.
EXAMPLE:
Target glycol = 25 gal × 0.30 = 7.5 gal pure glycol
Product needed = 7.5 ÷ 0.95 = 7.125 gal (typically round to 8 gal for ordering)
DI Water to add = 25 − 7.125 ≈ 17.875 gal
Note: Assumes the system starts empty with water added to reach 200 gallons. If there’s existing fluid, you’ll need to account for its volume and glycol concentration.

Safety Precautions:
- Read Label and SDS: Carefully review the product label and Safety Data Sheet before use.
- Keep Out of Reach: Store out of the reach of children.
- Avoid Mixing: Do not mix with other unknown corrosion inhibiting products.
By following these steps, you can effectively apply ARCTIC PROTECTION to protect your closed system from freezing and bursting.
