Propylene Glycol Arctic Protection AP-5, 55, 275

ARCTIC PROTECTION  is an inhibited, non-toxic, and premium propylene glycol-based antifreeze that provides exceptional freeze and burst protection for chilled water, hydronic, and other closed systems. Our standard propylene glycol is premium quality and the ingredients used in its manufacture are GRAS (generally recognized as safe), under Title 21, Part 182 of the US Code of Federal Regulations, where accidental or incidental contact with potable water could occur. We use quality ingredient for our proprietary inhibitor package, produced in house and blended for every custom order. For NSF, HT-1, Propylene Glycol, see our NSF Registered Product for more information.

For a custom blend of color or percentage please contact us for a custom quote, we need the following information: container size (5, 55, 275), total quantity in gallons, delivery zip code and color. (blue is standard, clear, green, pink, orange, red, yellow and more are available).

Directions:

This product must be used in accordance with the following directions and by professionals only.

  1. 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.
  2. 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.
  3. 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.
  4. Application guidance: Ice storage, fire sprinkler, and intermittently run hydronic systems may use burst protection. Chilled water and lawn sprinkler systems require freeze protection.
  5. 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.
  6. 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
  7. For corrosion protection, maintain a minimum concentration of 35–40% Arctic Protection.

*to find your concentration of Arctic Protection, check the front panel of the label, a sticker will read “PG  %”

EXAMPLE:

Target glycol = 200 gal × 0.35 = 70 gal pure glycol

Product needed = 70 ÷ 0.95 = 73.68 gal (typically round to 75 gal for ordering)

DI Water to add = 200 − 73.68 ≈ 126.3 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.

*NOTE – 100% ARCTIC PROTECTION DOES NOT CONTAIN AN INHIBITOR PACKAGE AND VAPCO IS NOT RESPONSIBLE FOR ISSUES ARISING IN SYSTEMS INSTALLED WITHOUT OUR INHIBITOR PACKAGE.
