WILKINS WTTA-5 THERMAL EXPANSION TANK

SPECIAL ORDER ITEM. Review Returns Policy before purchase. The Zurn Wilkins thermal expansion tank collection provides essential protection for hot water systems by managing pressure increases caused by thermal expansion. This ASME-certified unit features a robust carbon steel shell and an FDA-approved butyl rubber bladder that prevents water from contacting the interior, ensuring long-term reliability in commercial and industrial applications. By allowing water to expand into the pre-charge air chamber, the system maintains pressure below relief valve settings, effectively preventing unnecessary discharge. Designed for seamless integration, this tank includes a stainless steel system connection and a standard tire valve for easy on-site pressure adjustments to meet specific system requirements.
