Product Information
Microbiologically Corrosion Inhibitor for the Prevention of Generalized and Microbiologically Influenced Corrosion
Huguenot Laboratories FSS ProGuard 295UL - Concentrate is a unique proprietary formulation of non-hazardous corrosion inhibitors that provide maximum protection of “hard-to- reach-areas" within fire sprinkler systems. This highly inhibited technology allows for long term superior corrosion protection in both wet and dry sprinkler systems. When FSS ProGuard 295UL is placed in a hydrostatic environment, it provides unsurpassed corrosion protection in water, air interface, and above liquid levels. FSS ProGuard 295UL acts as a Corrosion Inhibitor protecting complicated values and the interior surfaces of piping and sprinkler components often difficult or impossible to reach. FSS ProGuard 295UL is non-flammable, non-odor, non-hazardous, bio- degradable, and low-foaming at all approved temperatures at 0.4%BV concentration.

Steel Corrosion Rates 80 times lower than untreated fire- sprinkler system city/municipal water
Verification Method
The water used for evaluation of the corrosion-rate test samples was local city (Northbrook, IL) tap water. Water chemistries vary by location and day. The results obtained may not accurately predict the corrosion rate of the treated water versus the local water chemistry. Therefore, the corrosion rate and resultant ratio may vary depending on the water chemistry where the corrosion inhibitor is used. The average corrosion rate for all samples exposed to untreated water was: 1.833 mpy The average corrosion rate for all samples exposed to the treated water was: 0.023 mpy The resultant ratio of corrosion rate for treated water as compared to untreated water was: 80 Test coupons of ASTM A108, Grade 1010 steel were prepared and exposed to Northbrook, IL city tap water treated with the corrosion-control additive at a concentration of 1% by volume using the method described in UL 2901A, Corrosion Control Additives for Use in Fire Sprinkler Systems. An additional series of test coupons were prepared and exposed to untreated water for comparison to the test coupons exposed to water treated with the corrosion inhibitor. The following conditions were used for the exposures for a 90 day duration: a) Total immersion at 70 ± 4°F (21 ± 2°C) b) Total immersion at 150 ± 4°F (66 ±2 °C) c) Partial immersion at 70 ± 4°F (21 ± 2°C) d) Partial immersion at 150 ± 4°F (66 ± 2 °C) The corrosion rate in mils per year (mpy) was determined by calculating the weight loss over the exposed area of each sample coupon in accordance with the Standard on Water Additives for Fire Control and Vapor Mitigation, NFPA 18A. For purposes of calculating an average, any evidence of weight gain for a sample was considered to be a corrosion rate of zero (0).
