This ASME-constructed vessel is engineered to effectively absorb the forces of expanding water, safeguarding your domestic plumbing infrastructure from damaging pressure build-ups. The Bell & Gossett PTA-5, bearing model number 1BN346LF, provides a robust solution for maintaining system equilibrium in varying thermal conditions.
Designed with an advanced bladder system, this tank utilizes an FDA-approved polypropylene liner and a heavy-duty butyl diaphragm. This internal mechanism creates a physical barrier that isolates the system water from the steel shell, preventing corrosion and ensuring the longevity of your hydronic equipment.
Key System Performance Baselines:
- ASME Construction: Meets rigorous industry standards for pressure vessel safety and reliability.
- Water Isolation: Butyl diaphragm prevents direct contact between water and the steel shell to minimize corrosion.
- FDA-Approved Materials: Incorporates food-grade components suitable for high-quality domestic water applications.
⚠️ Application Profile: Ideal for residential and light commercial domestic water systems requiring pressure stabilization, thermal expansion control, and enhanced equipment longevity.
