More Information

The ProTech300. It’s been Improved! The ProTech300 is a new and improved formula with chemical detection technology. We have taken it to the next level. It has the highest level of protection for the wood boiler than other brand-name boiler treatment. It has 3 levels of protection. That means 3 Active ingredients in it.

The 3 Protection “Levels” are:

1. Nitrite

2. Phosphonate

3. Anodic inhibitor.

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 ProTech300 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 300Test kit. The manufacturers can’t tell the difference if you are using their expensive brand or our ProTech300, so send it into their labs with confidence.

ProTech 300 Protects Cast Iron, Mild Steel, Titanium and Stainless Steel

Our ProTech 300 Boiler Treatment will:

  • Protect your wood boiler from rust, corrosion, and scale
  • Balance pH and Alkalinity

works good

I have been using this product for 3 years now and it seems to be doing its job. I add it to my outdoor boiler at the end of the season.

Good Product

Have used Protech for several years with excellent results. The specs call for 1 gallon treating 300 gallons and my OWB holds 150 so this year I used the amount called for 1/2 gallon which is way less than previously so we'll see next time if the doseage is correct but I have nothing but high marks for the product itself!
