The \u003cstrong\u003eSU105-2\u003c\/strong\u003e model by \u003cstrong\u003eBell \u0026amp; Gossett\u003c\/strong\u003e serves as a critical component in hydronic systems requiring consistent temperature management and high thermal efficiency in a compact footprint.\u003c\/p\u003e\u003cp\u003eThe unit operates by circulating the liquid to be heated through a series of internal tubes while steam fills the surrounding shell. As the steam releases latent heat upon contact with the cooler tubes, it condenses and transfers thermal energy directly into the fluid stream. This shell and tube design ensures maximum surface area contact for superior heat exchange rates even in demanding industrial or commercial plumbing applications.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal Efficiency:\u003c\/strong\u003e Optimized for rapid heat transfer in instantaneous demand cycles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating:\u003c\/strong\u003e Designed to withstand standard commercial steam and fluid pressure requirements.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurability:\u003c\/strong\u003e Built with robust materials to prevent corrosion and scale buildup during extended service.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Ideal for commercial boilers, domestic hot water heating systems, industrial process fluid temperature control, and large-scale hydronic space heating loops.\u003c\/p\u003e","brand":"Bell \u0026 Gossett","offers":[{"title":"Default Title","offer_id":43136991854686,"sku":"SU105-2","price":11698.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/SU105_2_image_28fd46fa-58b5-4278-a248-7d52d54fb174.png?v=1786161911","url":"https:\/\/nationalboilersupply.com\/products\/bell-gossett-su105-2-instantaneous-shell-and-tube-heat-exchanger","provider":"National Boiler Supply","version":"1.0","type":"link"}
