Freez-Kontr'l FG Clear

Video Overview

Description

Freez-Kontr’l FG is clear (no dye added) full concentrate propylene glycol-based product especially suitable for use in food and beverage equipment where incidental contact with food or potable water is possible. Freez-Kontr’l FG is NSF listed as an HT-1 fluid that is manufactured with ingredients classified as Generally Regarded as Safe (GRAS) by the FDA. The product is ideal for top-off adjustments for freeze/burst protection where existing heat transfer fluid already has a colorant added for leak detection purposes within the closed loop system. A fully formulated product, it contains an inhibitor package that controls corrosion of metals, helps prevent scaling and fouling of heat transfer surfaces, and buffers the pH to maintain it in the optimum operating range.

Specifically formulated for use in closed loop refrigeration equipment where the incidental contact of the product with food or potable water is possible. Ideally suitable for use in food and beverage equipment or other HVAC applications where a NSF listed HT-1 formulated propylene glycol-based product is required.

Directions

This product must be used in accordance to the following directions by HVACR professionals only.

  1. Clean new or lightly corroded existing systems with Nu-Calgon System Cleaner (4370-08) prior to installation of Freez-Kontr’l. Do not use with galvanized steel.
  2. Extensively corroded existing systems should be cleaned using an inhibited acid such as Season Start Scale Remover or Liquid Scale Dissolver. Job should be handled by an experienced serviceman. All necessary replacements and repairs should be made.
  3. The concentration of required glycol-based Freez-Kontr’l will depend on the kind of protection needed. There are two types of protection: burst protection and freeze protection. Burst protection prevents bursting or other mechanical damage, but it is not enough to keep solution pumpable. Freeze protection requires more glycol, and it prevents the formation of ice crystals at the lowest temperature experienced by the fluid. This assure fluid can be pumped at the lowest experienced temperature.
  4. Typically, ice storage systems, fire sprinkler systems and intermittently run hydronic systems may be fine with burst protection while chilled water and lawn sprinkler systems need freeze protection.
  5. See the chart and select the lowest expected ambient temperature, then go to a temperature 5ºF colder to assure protection. Decide on type of protection, and identify the solution percentage that must be made up of Freez-Kontr’l.
  6. Calculate or establish system volume in gallons, and multiply this volume by the percentage identified above. This will tell you the number of gallons of Freez-Kontr’l required.
  7. For optimum corrosion protection, a minimum concentration of 30% is recommended.
