(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.
The CHX is built tough
enough to withstand the
demanding conditions
found in condensing
applications. All materials
used in the CHX are
inherently corrosion
resistant and are treated
with advanced corrosion-
proof coatings for extra
protection. The headers
are bronze, the heat
exchanger tubes are
made of cupro-nickel and
are coated with a
condensate impervious
epoxy enamel. All
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.
By segregating condensation from the primary
heat exchanger and the combustion chamber,
the CHX produces ultra-high efficiency without
sacrificing product life.
