ProTech 300 Provides protection for your wood boiler from rust, corrosion, and scale. ProTech 300 boiler water treatment has been designed to be used in manufacturer's boiler treatment programs. Adding 1 gallon of ProTech 300 to 300 gallons of boiler fill water will yield +/- 1000 ppm nitrite. Suggested nitrite levels are: 750 ppm = Adequate, 1000 ppm = Good, 1500 ppm = Great. Dose the system accordingly to the required control levels set by your boiler manufacturer and your system's nitrite needs based on test results. You can determine the needs of your system by testing your boiler water using our do-it-yourself test kit. See our 300 Test kit.
