Specifically engineered for the \u003cstrong\u003eModel 135\u003c\/strong\u003e series, this tank acts as a critical buffer, absorbing the expansion forces created by fluctuating system water temperatures to maintain consistent pressure throughout your hydronic loop.\u003c\/p\u003e\u003cp\u003eAs water heats up and expands, the tank provides the necessary volume to prevent excessive pressure buildup, protecting system components from premature wear or failure. By maintaining precise atmospheric or air-cushion balance, it ensures reliable operation during both startup and peak heating demand cycles.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Stability:\u003c\/strong\u003e Effectively absorbs expansion forces to prevent relief valve discharge.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReliability:\u003c\/strong\u003e Engineered for long-term durability in closed-loop hydronic environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem Protection:\u003c\/strong\u003e Minimizes stress on pipes, fittings, and boilers by mitigating pressure spikes.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Ideal for residential and light commercial closed-loop hydronic heating systems requiring robust thermal expansion management.\u003c\/p\u003e","brand":"Bell \u0026 Gossett","offers":[{"title":"Default Title","offer_id":43124058390622,"sku":"116669","price":2459.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/116669_image_0437231a-9956-4daa-acdd-3218791ce673.png?v=1786031163","url":"https:\/\/nationalboilersupply.com\/products\/bell-gossett-116669-model-135-compression-tank","provider":"National Boiler Supply","version":"1.0","type":"link"}
