Efficiently manage thermal expansion in your hydronic heating or chilled water system with the PS040-125 40-gallon expansion tank from Taco. This high-capacity vessel is engineered to accommodate the volumetric changes of water as it heats and cools, effectively preventing excessive pressure spikes that can damage delicate system components. By maintaining constant operating pressure, the PS040-125 ensures your boiler and circulation loops function at peak efficiency while extending the overall service life of your mechanical infrastructure.

The unit functions by utilizing an internal flexible diaphragm that isolates system water from the pressurized air cushion. When water volume increases during heating cycles, the fluid enters the tank and compresses the air-filled bladder, providing the necessary space to keep pressure within safe operational limits. As temperatures drop and the water contracts, the air cushion gently forces the fluid back into the piping circuit, ensuring a consistent and responsive hydronic environment.

Key System Performance Baselines:

  • Pressure Regulation: Provides consistent thermal stabilization to prevent relief valve discharge.
  • Extended Longevity: Protects system pumps and heat exchangers from damaging pressure fluctuations.
  • Robust Construction: Built with high-grade steel and a durable, heavy-duty diaphragm membrane.
  • Energy Efficiency: Supports optimized system performance by maintaining steady-state conditions.

⚠️ Application Profile: Ideal for large-scale residential hydronic heating systems, commercial chilled water loops, and heavy-duty radiant heating applications requiring high-volume fluid expansion compensation.
