Thermal Expansion Tanks

Thermal expansion tanks are designed for pressure control in portable water systems. The building’s water heater or water heating system typically creates thermally expanded water. A properly sized thermal expansion tank will accommodate this additional volume of water through expansion during the heating cycle and control the system pressure increases, keeping pressures from reaching critical limits. The tank uses compressed air to maintain system pressures by accepting and expelling the changing volume of water as it heats and cools. These tanks are designed using a flexing butyl barrier that separates the stored water from the captured pressure control air cushion. This barrier, a replaceable bladder or fixed diaphragm, allows the water to be contained within the bladder preventing corrosion and potential water logging.

Hydropneumatic Tanks

There are several different functions that a hydropneumatic tank can perform. In a booster pump application, it can provide water to the system during periods of a no flow shutdown of the booster pump or it can provide water to replace leak loads. In a well water application, it can provide the desired volume of water required between the pump shut down pressure and the pump turn on pressure.
