ProTech 300 is a rust inhibitor and boiler water treatment designed to integrate with your boiler program, helping systems run smoother through seasonal changes and heavy use.\u003c\/p\u003e\n\u003ch2\u003eWhat ProTech 300 does\u003c\/h2\u003e\n\u003cp\u003eProTech 300 is formulated to work with standard boiler fill water and aligns with typical manufacturer treatment programs. When you add one gallon to 300 gallons of fill water, you can expect about 1000 ppm nitrite in the circulating solution. This level is one of several control points used to balance protection with system performance. The product is designed to complement existing maintenance routines without requiring a major system overhaul.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces rust formation on hot surfaces and inside piping\u003c\/li\u003e\n  \u003cli\u003eLimits corrosion of boiler components and fittings\u003c\/li\u003e\n  \u003cli\u003eSlows mineral scale accumulation on heat transfer surfaces\u003c\/li\u003e\n  \u003cli\u003eSupports straightforward monitoring with a DIY nitrite test kit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eHow to dose and test\u003c\/h3\u003e\n\u003cp\u003eFollow your boiler manufacturer’s guidance for nitrite targets. In a typical setup, adding one gallon of ProTech 300 to 300 gallons of fill water yields approximately 1000 ppm nitrite. You can measure nitrite with the DIY test kit and adjust dosing to hit the desired range, usually between 750 and 1500 ppm depending on your system’s requirements.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eStart with the standard ratio for your system capacity\u003c\/li\u003e\n  \u003cli\u003eTest nitrite with the DIY kit before and after dosing\u003c\/li\u003e\n  \u003cli\u003eIncrementally adjust to stay within your target range\u003c\/li\u003e\n  \u003cli\u003eRecord results to track changes over seasons\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eReal-world use cases\u003c\/h3\u003e\n\u003cp\u003eIdeal for seasonal operation, cabins, or remote setups where reliability matters.
