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

Armstrong Vortex Air Separators
- Applications-Air removal from hydronic and HVAC systems – air can get trapped during initial fill, during routine equipment maintenance (including pressure upkeep), and due to the use of cooling towers.
- Description-The Armstrong vortex air separators create a vortex or whirlpool action, sending the heavier air-free water to the outer portion of the tank, and allowing the lighter air-entrained water mixture to move into the lower-velocity center. At the center of the vortex the air is released from the water, forms bubbles and exits through an air vent or compression tank installed above it.
- Materials (MOC)-Cast iron or fabricated steel (shell), stainless steel mesh (strainer)
Y-Type Strainers (ANSI 150#, 300#)
Applications:
Strainer can be used in liquid as well as gas line, Regulator and valve protection, steam traps protections, flow meter and pump protections, heat exchanger and refrigeration set protection, Suitable for Hazardous environments. Y-Strainers and pot basket type strainers is a device for mechanically removing unwanted solids from liquid, gas or steam lines by means of a perforated or wire mesh straining element. Where the amount of material to be removed from the flow is relatively small, resulting in long intervals between screen cleanings, the strainer screen is manually cleaned by shutting down the line and removing the strainer capTechnical Data :
