Maintain optimal pressure regulation in your closed-loop HVAC infrastructure with the FXA-NVA-500 replacement bladder. Specifically engineered for the Wessels 2210500 expansion tank, this heavy-duty bladder serves as a vital barrier between system fluid and the air cushion, effectively absorbing thermal expansion to prevent damaging pressure spikes and relief valve discharge.
The bladder functions as a flexible diaphragm that expands and contracts in response to fluid temperature fluctuations. By isolating the system water from the tank shell, it prevents corrosion and minimizes air absorption, ensuring the long-term integrity and energy efficiency of your hydronic or chilled water system.
Key System Performance Baselines:
- Pressure Regulation: Absorbs volumetric changes to stabilize system PSI.
- Fluid Isolation: Prevents direct contact between system water and steel tank walls.
- Durability Standard: Constructed for high-cycle resilience in demanding commercial HVAC loops.
⚠️ Application Profile: Ideal for commercial boiler systems, large-scale chilled water loops, and hydronic radiant heating assemblies requiring reliable pressure vessel maintenance.
