Directions:
This product must be used in accordance with the following directions and by professionals only.
- 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.
*to find your concentration of Arctic Protection HT, check the front panel of the label, a sticker with “PG %”
EXAMPLE:
Target glycol = 350 gal × 0.40 = 140 gal pure glycol
Product needed = 140 ÷ .60 = 233.33 gal (round to 233 gal; typically round to 235 gal for ordering)
DI Water to add = 350 − 233.33 ≈ 116.67 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.
By following these steps, you can effectively apply Arctic Protection to safeguard your closed system from extreme temperatures.
Additional Tips:
- Regular Maintenance: Quarterly check the antifreeze concentration to ensure optimal protection.
- Consult Professional: For complex systems or specific concerns, consult a professional for guidance.
- Safety Precautions: Always refer to the product’s Safety Data Sheet for detailed instructions and safety information.
