Designed for durability and precision, this \u003cb\u003eHFT-160V\u003c\/b\u003e model effectively absorbs the increased water volume caused by temperature fluctuations, preventing pressure surges and protecting critical system components from stress.\u003c\/p\u003e\u003cp\u003eThis vessel operates using a heavy-duty, field-replaceable diaphragm that maintains a pressurized air cushion to balance system water pressure. By isolating the expansion fluid from the system air, the tank prevents oxygen absorption and reduces the likelihood of corrosion or air-binding in terminal units.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eSystem Compatibility:\u003c\/b\u003e Engineered for use in closed-loop hydronic heating applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eOperational Stability:\u003c\/b\u003e High-capacity 86-gallon design ensures consistent pressure regulation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eDurability Standard:\u003c\/b\u003e Constructed with robust materials to withstand demanding HVAC environments.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Ideal for commercial boiler rooms, multi-zone residential heating systems, and industrial fluid temperature control circuits where pressure stabilization is required.\u003c\/p\u003e","brand":"Bell \u0026 Gossett","offers":[{"title":"Default Title","offer_id":43127882186846,"sku":"1BN335","price":1178.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/1BN335_image_217f28b6-4924-4689-b5a9-05a4874e9ffd.jpg?v=1786058674","url":"https:\/\/nationalboilersupply.com\/products\/bell-gossett-1bn335-hft-160v-86-gallon-hydronic-expansion-tank","provider":"National Boiler Supply","version":"1.0","type":"link"}
