Maintain optimal system pressure, prevent hydraulic shock, and protect high-efficiency boilers with our premium selection of commercial and residential Hydronic Expansion Tanks. Engineered for closed-loop heating, chilled water, and radiant systems, these vessels absorb thermal expansion to eliminate dangerous pressure fluctuations and prevent system waterlogging.

Our inventory features industry-standard configurations for reliable loop management:

  • ASME-Certified Tanks: Built and code-stamped to meet strict Section VIII compliance for commercial mechanical rooms, institutional facilities, and heavy-duty industrial HVAC networks.
  • Heavy-Duty Diaphragm Design: Utilizing ultra-thick, fixed butyl/EPDM diaphragms securely clamped to the vessel walls, completely isolating air from system water to prevent air migration.
  • Corrosion-Resistant Construction: Fabricated from deep-drawn steel shell matrixes finished with industrial-grade primers and coatings to ensure a long, maintenance-free operational life.
