It protects copper, brass, aluminum, and steel from corrosion while controlling scale formation that reduces heat transfer efficiency. The inhibitor helps maintain system pH within an acceptable operating range and is safe for use with standard PEX, PEX-Al-PEX, and rubber tubing. It does not contain nitrite, making it a cleaner option for systems where nitrite-free chemistry is required. Licensed HVAC technicians and plumbers working on boiler-based heating systems are the primary installers and service professionals for this product.\u003c\/p\u003e\n\u003cp\u003epro-tek 922 is intended for hot-water, closed-loop heating systems in residential and light commercial applications. It is compatible with both inhibited and uninhibited propylene glycol and ethylene glycol mixtures, and it boosts the corrosion protection already present in pre-inhibited glycol blends. Typical applications include hydronic boiler loops, radiant floor heating circuits, and fan coil systems where copper, brass, aluminum, or steel components are present. The product is packaged in a 1-gallon container for single-system treatments or top-off service calls.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInhibits corrosion on copper, brass, aluminum, and steel surfaces\u003c\/li\u003e\n  \u003cli\u003eControls scale formation to maintain heat transfer efficiency\u003c\/li\u003e\n  \u003cli\u003eHelps maintain system pH balance in closed-loop circuits\u003c\/li\u003e\n  \u003cli\u003eCompatible with inhibited and uninhibited propylene and ethylene glycol mixtures\u003c\/li\u003e\n  \u003cli\u003eSafe for use with PEX, PEX-Al-PEX, and rubber tubing\u003c\/li\u003e\n  \u003cli\u003eNitrite-free formula; environmentally friendly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in hot-water, closed-loop heating systems incorporating copper, brass, aluminum, and steel components.

Before servicing or adding chemical treatment, shut down the boiler and allow the system to cool to a safe handling temperature. Follow the system manufacturer's dosing guidelines and local mechanical codes when introducing chemical additives to a pressurized loop. Always verify compatibility with existing fluid chemistry before mixing with other inhibitors or treatments.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Corrosion and Scale Inhibitor\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Hot-Water, Closed-Loop Heating Systems; Copper, Brass, Aluminum, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContainer Size\u003c\/strong\u003e: 1 gallon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContainer Type\u003c\/strong\u003e: Can\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGlycol Compatibility\u003c\/strong\u003e: Inhibited and uninhibited propylene glycol and ethylene glycol mixtures\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTubing Compatibility\u003c\/strong\u003e: PEX, PEX-Al-PEX, rubber tubing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNitrite Content\u003c\/strong\u003e: None\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: RHOMAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: pro-tek 922\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RHOMAR","offers":[{"title":"Default Title","offer_id":51467763548466,"sku":"PRO-TEK 922","price":78.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313946384.jpg?v=1783912583","url":"https:\/\/voomisupply.com\/products\/rhomar-pro-tek-922-corrosion-scale-inhibitor-1-gallon","provider":"Voomi Supply","version":"1.0","type":"link"}
