Bryan Indirect
Heat Exchanger
Robust heart of the Bryan Commercial
Pool heater is the all-copper Heat
Exchanger, which transfers heat from
the hot primary water to the pool water
as it flows through the exchanger. Since
the exchanger coils are not subjected
directly to the intense heat of the fire,
but only to the hot water within the heater,
there is no scale or corrosion problem.
Bryan Indirect Commercial Pool Heaters assure addi-
tional years of maintenance-free operation...even in
areas where hard water creates real problems. This
superior performance is made possible by an exclu-
sive Bryan Indirect Heat Exchanger that confines
primary water to a small circulating system embrac-
ing only the water tubes and the vessel proper. The
water in this system never leaves the heater. Any
natural minerals or scale it may contain are deposited
early in the life of the heater — never enough to impair
top efficiency of the heater. Following this initial de-
posit, it's like the heater was circulating distilled
water—no further buildups. Pool water is circulated
through the heat exchanger tubes where it is warmed
indirectly by water maintained at constant tempera-
ture by the heater. Deposits seldom occur in this low
temperature method of Bryan heating.
Same unit heats pool, domestic water and build-
ing — If you desire a domestic hot water supply, a
second heat exchanger will be built into your Bryan
Heater where thermostatic controls accurately gov-
ern the temperature of the water you draw. For space
heating, water is circulated directly from the heater
through your building's heating system.
Your pool temperature is always "just right" —
The temperature you desire for your pool water is
accurately regulated by a thermostatic control at the
heater. It permits circulation at the temperature called
for, regardless of external weather conditions.
Bryan commercial pool heater features
Scale-free — The Bryan Indirect Heat Exchanger elimi-
nates costly periodic de-scaling. No buildup of scale
means no buildup of fuel costs.
Condensation-free — Bryan Indirect Heaters operate at
desirable water temperatures, completely independent of
pool water temperatures or circulation rates, thus elimi-
nating damaging condensation.
Corrosion-free — Pool water touches only the all-
copper Heat Exchanger, and at low temperatures, thus
eliminating build-up of solids.
Open circulation — No thermostatic tempering valves
or restricting bypass valves to lower filtration rate.
Economical — Time-proven for low maintenance, trouble-
free, continuous service, high efficiency.
Fully approved — Bryan Indirect Heaters are designed
and built to the requirements of the ASME Code.
