Expansion Vessels
API EnergyTM Expansion vessels are commonly used to protect closed water heating-cooling systems from being exposed to high pressure. Expansion vessels work by being part filled with air, this then protects the system by cushioning any shock which is caused by water hammer and also absorbing any excessive water pressure which may have been caused by thermal expansion.
HVAC Applications
In closed heating-cooling systems, the water expands or contracts as the system is heated up or cooled down respectively. Expansion vessels are used to compensate for the fluctuations in volume between maximum and minimum temperature within a permissible range.
