Efficiently manage thermal expansion in domestic water systems with the Bell & Gossett PTA-447 expansion tank, part number 1BN358LF. Engineered for commercial and residential applications, this robust vessel absorbs the forces of expanding water as temperatures rise, effectively preventing hazardous pressure build-ups that can compromise system integrity.
This diaphragm-style tank features an FDA-approved polypropylene liner and a heavy-duty butyl diaphragm. This design ensures that potable water is completely isolated from the steel shell, maintaining water quality while providing a reliable barrier against pressure fluctuations in the plumbing network.
Key System Performance Baselines:
- ASME Construction: Engineered to meet stringent pressure vessel standards for maximum safety.
- Contamination Shield: Butyl diaphragm and polypropylene liner prevent contact between water and steel.
- System Protection: Effectively absorbs expansion forces to extend the lifespan of system components.
⚠️ Application Profile: Ideal for protecting domestic hot water heaters, high-rise building plumbing systems, and commercial water supply lines where thermal expansion must be regulated to prevent relief valve discharge.
