By serving as the \u003cstrong\u003eModel 505\u003c\/strong\u003e expansion vessel, it provides the necessary buffer to handle the volumetric expansion of system fluid as temperatures fluctuate during heating cycles.\u003c\/p\u003e\u003cp\u003eAs water heats, it expands and exerts significant pressure on the piping infrastructure. The compression tank features an air cushion that compresses under this rising pressure, effectively absorbing excess volume and preventing the activation of pressure relief valves or damage to system components.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Regulation:\u003c\/strong\u003e Maintains consistent system pressure to prevent aeration or cavitation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExpansion Control:\u003c\/strong\u003e Efficiently absorbs volumetric expansion to prevent relief valve discharge.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorrosion Prevention:\u003c\/strong\u003e Minimizes fresh water makeup, reducing the introduction of oxygen into the loop.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Primarily installed in residential and light commercial hydronic heating systems to ensure structural integrity and operational longevity.\u003c\/p\u003e","brand":"Bell \u0026 Gossett","offers":[{"title":"Default Title","offer_id":43124061339742,"sku":"116675","price":11847.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/116675_image_7c9422ba-47f4-4766-b26f-699af95339f3.png?v=1786031408","url":"https:\/\/nationalboilersupply.com\/products\/bell-gossett-116675-model-505-compression-tank","provider":"National Boiler Supply","version":"1.0","type":"link"}
