Maintain system integrity and prevent pressure fluctuations in potable water systems with the Bell & Gossett 1BN320LF, also known as the PT-30V. This reliable expansion tank is engineered to absorb excess water volume created by thermal expansion during the heating cycle, effectively mitigating pressure spikes that can stress pipes, valves, and water heater components.
The unit features a pre-pressurized air chamber separated from the potable water supply by a durable, FDA-approved butyl diaphragm. When the water temperature rises and volume expands, the water pushes against the diaphragm, compressing the air cushion to absorb the increase and prevent the relief valve from discharging water unnecessarily.
Key System Performance Baselines:
- Thermal Expansion Control: Effectively stabilizes system pressure during heating cycles.
- Diaphragm Reliability: Heavy-duty, FDA-approved construction ensures long-term potable water safety.
- Corrosion Resistance: Engineered with premium materials to resist internal and external rust.
⚠️ Application Profile: Ideal for residential and light commercial potable water applications, including tank-type water heaters, boiler feed systems, and closed-loop domestic hot water supplies.
