The primary function of an expansion tank is to accommodate volumetric expansion caused by temperature fluctuations in HVAC or cooling systems. It also provides pressure stabilization, air venting, and water replenishment, ensuring safe and stable system operation.
Core Functions
1、Expansion Water Accommodation: When water temperature rises and the volume expands, the expansion tank provides space to store excess water, preventing overpressure and damage to pipes or equipment.
2、Pressure Stabilization: By connecting an expansion tube or internal air bladder, the system maintains stable static pressure and buffers pressure fluctuations (such as pressure surges during pump startup and shutdown).
3、Water Replenishment: When water temperature drops or a system leak occurs, the water stored in the tank automatically replenishes the system to maintain water balance.
