Expansion Tanks

Applications

​

Pressure stabilization in water-based mechanical systems such as booster installations, boiler systems, and chiller plants

 

Description

 

Compared to conventional designs, Armstrong Expansion Tanks can reduce tank sizes by up to 80%. By absorbing and releasing the fluctuating volume of water as it heats and cools, expansion tanks use compressed air to maintain system pressures. The expanded water is separated from the factory-pre-charged pressure-regulating air cushion by diaphragm or bladder tank designs, which can be modified on-site to satisfy system specifications.

 

Materials

 

Carbon steel (shell), heavy-duty Butyl (diaphragm)
