Small size. Big impact.
Mechanical Design:
Design pressures up to 435 psig.
Maximum design temperature up to 450˚F.
Minimum design temperature to -310˚F.
Connections:
From 1/2 inch to 4
inch. Standard
connection options
include NPT, SAE
Flanged and Sweat.
Custom connections
available.
Capacity:
Up to 800 GPM
and 350 Sq.ft.
of surface area.
Construction Codes:
Available codes
include UL, CRN, and
ASME Code Stamp.
Mounting:
Reduce mounting
costs with optional
threaded studs or
integral mounting
bracket.
Materials:
Stainless Steel 316L
plates. Copper
brazed material.
By using a brazing process we
eliminated the need for gasketed
or rolled joints commonly found in
traditional exchangers. This allows
for higher operating pressures and
temperatures with no maintenance
and no leaks. The corrugated
plates easily handle highly viscous
fluids, turbulating them for
maximum effi
ciency
. Corrosion-
resistant materials ensure a long
operating life.

1) Provides approx. 2°F per hour heating with 180°F boiler to achieve 80°F pool temperature.
2) Pool water flow rate usually requires flow by pass from main pool circulation.
3) Chlorinated pool water can be corrosive to SS316L and Copper. P roper control of chlorine
levels is required or alternate materials of construction should be considered.
