Armstrong Expansion Tanks
- Applications-Pressure stabilization in water based mechanical systems such as booster installations, boiler systems, and chiller plants
- Description-Armstrong Expansion Tanks are designed to reduce tank sizes by up to 80% over standard designs. Expansion tanks use compressed air to maintain system pressures by accepting and expelling the changing volume of water as it heats and cools. Diaphragm or bladder tank designs isolate the expanded water from the pressure controlling air cushion – which is pre-charged at the factory and can be adjusted in the field to meet final system requirements
- Materials (MOC)-Carbon steel (shell), heavy duty Butyl (diaphragm)
- Performance range-AET plain steel expansion tanks: 15 to 525 USgpm flow.
AX diaphragm expansion tanks: 8 to 211 USgpm flow.
Type L bladder type expansion tanks: 10 to 1056 USgpm flow.
Description
Benefits & Features
Lowest footprint
- Space saving design for up to 80% reduced footprint over standard tank designs
Low operating cost and risk
- Eliminates air ingress and dampens pressure transients (water hammer) for reduced system corrosion and stress, ultimately extending service intervals and overall system life.
- Stabilizes system pressure, maintaining optimum levels of a critical operating parameter.
- Reduces need for chemical treatment.
