Wessels NLA-5000 - NLA-5000 Series Bladder Expansion Tank

Efficiently manage fluid expansion and protect your HVAC infrastructure with the Wessels NLA-5000 bladder expansion tank. This reliable unit, identified by part number NLA-5000, is engineered specifically to absorb excess fluid volume in closed-loop heating and chilled water systems, effectively limiting internal pressure fluctuations to prevent component damage.

The vessel utilizes a heavy-duty, replaceable bladder mechanism that creates a physical barrier between the system fluid and the air cushion. As temperatures rise and fluid expands, it is forced into the bladder; as the system cools, the pressurized air forces the fluid back into the piping, maintaining consistent operating pressures throughout the cycle.

Key System Performance Baselines:

• Enhanced Longevity: Protects pumps and seals by mitigating pressure spikes.
• Replaceable Bladder: Simplifies maintenance and extends the service life of the tank assembly.
• System Stability: Maintains precise equilibrium in closed-loop hydronic networks.
• Robust Construction: Built to withstand rigorous industrial and commercial environmental demands.

⚠️ Application Profile: Ideal for commercial high-rise buildings, campus-wide hydronic heating systems, large-scale chilled water loops, and boiler room pressure management.
