Armstrong heat exchangers provide dependable, efficient performance for a broad range of commercial and light
industrial applications where water and liquid must be quickly heated or cooled. Armstrong heat enchangers offer
industry-wide compatibility and are available in several materials and working pressures to suit most requirements.
The standard Armstrong design meets or exceeds Section 8, Division 1 of the ASME code.
Heat Exchangers
A compact Brazed Plate heat exchanger, the ABX model is highly effective
for heat recovery applications. It is designed for pressures up to 450 psi
(3102 kPa) and temperatures up to 385°F (196°C). ABX units are ASME
Code designed and available from stock.

Armstrong PHE plate and frame heat exchangers consist of a number of specially corru-
gated stainless steel plates assembled in a frame and bolted between two pressure plates
(one fixed and the other adjustable). High turbulence is created in the liquid flow channels,
producing very high heat transfer coefficients and resulting in a compact efficient heat
exchanger. Units are also available with titanium plate construction.

Armstrong’s economical U-tube heat exchangers offer durable construction
with a removable bundle. Armstrong U-tube heat exchangers are recommend-
ed where a low cost removable bundle design is needed for clean tube side
fluids. The U-bend design provides a long service life for the exchanger by
eliminating the effects of thermal expansion and construction. All units feature
carbon steel construction with
3
/
4
inch copper tubes and a rugged cast iron
head. Optional materials are available for head, tube sheet and tubing.

W, WS and WR U-Tube Heat Exchangers
Armstrong double wall U-tube (tube-in-tube design) heat exchangers are designed for applications where it is critical that the
shell and tube side fluids remain separated, e.g., potable water heaters. These units, in the event of a leak, allow the liquid to
drain to atmosphere. Where an upgrade to potable water is required, the tube bundle from a WX heat exchanger will fit the
shell of an existing Armstrong U-Tube heat exchanger.

copper tubing, brass tube supports, a carbon steel tubesheet and a tank
collar. Tubing is available in single or double wall copper and cupronickel.
Tubesheets are also available in brass or stainless steel.
