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.
