ADVANCED BURNER TECHNOLOGY
The heart of any boiler is the burner. It’s a critical
component that’s got to be designed right. That’s
why Raypak spent over four years perfecting the
ADB burner. The result is an industrial grade, fan-
assisted burner that provides superior perfor-
mance and is practically indestructible.
Standard high efficiency boilers use burners that
are either flimsy flame retention screens that burn
out, or radial perforated burners that eventually
clog and operate at reduced efficiencies. Unlike
these burner designs, the patented advanced
design burner will not clog or burn out. In fact,
Raypak is so confident, the new burner head is
backed with a TEN YEAR UNCONDITIONAL WARRANTY.
The ADB’s burner utilizes a solid metal bluff-body
burner head to generate a high-intensity aerody-
namically stabilized flame. The burner’s turbulent
mixing action reduces residence time and increas-
es flue gas recirculation. The result is clean, effi-
cient combustion with NOx emissions well within
the limits of the most restrictive air quality require-
ments.*
This is one tough burner and the warranty proves it.
* NOx emissions:
0-30 ppm depending on combustion air quality and
gas composition.
CENTRAL POINT WIRING AND DIAGNOSTICS
Raypak boilers have a well earned reputation for
being easy to service. The ADB is no exception. In
fact, the ADB sets a whole new standard for ser-
viceability – because it’s the first commercial boiler
to incorporate central point wiring (CPW).
ERROR
Unlike older control technologies, CPW individually
monitors each and every boiler control and safety
function. Using an intuitive LED display referred to
as the Operation Status Center, CPW gives split-
second feedback on boiler firing status. Should
service be required, the ADB will even indicate
which component requires attention by illuminat-
ing the appropriate fault LED located on the ADB’s
U-2 Diagnostics Panel.

FLEXIBILITY
.
non-stainless internal fittings are either epoxy
coated or are chemically immune. The tube bundle
casing is fabricated from AL29-4C stainless steel,
and the outer jacket has an electrostatically applied
powder coat finish that is baked-on for superior
corrosion resistance and extra long life.
THE CONDENSING HEAT EXCHANGER (CHX)
The CHX is a scavenging heat exchanger that has
been specifically designed to capture the maximum
amount of energy from the ADB’s exhaust gases.
When used with a pre-heat tank and a storage tank,
the ADB/CHX system can squeeze out an amazing
97% of all heat of combustion energy contained in
the flue gases.
By segregating condensation from the primary
heat exchanger and the combustion chamber,
the CHX produces ultra-high efficiency without
sacrificing product life.
The CHX is built tough
enough to withstand the
demanding conditions
found in condensing
applications. All materials
used in the CHX are

Vertical, cylindrical, multi-pass
heat exchanger captures all
radiant energy, eliminating
the need for heavy refractory.
TUBE SHEET CONSTRUCTION
Eliminates the repair and
maintenance problems associated
with rolling tubes directly into
a casting.
CUPRO-NICKEL FINNED TUBES
Provide fast, efficient heat transfer with extended
tube life. Will not corrode or erode and can handle
aggressive and hard water with ease.
VIEWING PORT
Allows easy fine-tuning of the power burner.
SMALL FOOTPRINT
The ADB occupies less than 51/2 sq. ft. of floor space.
