igh efficiency boilers were introduced in
response to the energy crisis of the

seventies. Most first generation high
efficiency boilers were simply standard units that
had been hurriedly modified to boost efficiency.
These boilers obtained higher efficiencies by
permitting steady-state condensation in the heat
exchanger and in the combustion chamber.
Failure to adequately protect the combustion
chamber and heat exchanger from the corrosive
effects of condensate meant that most first
generation units failed prematurely. The units
condensed, eventually corroded, and finally
were discarded.

Manufacturers learned from their mistakes. They
upgraded materials, redesigned heat exchangers
and refined their manufacturing techniques. The
second generation of high efficiency boilers,
which began to appear in the late eighties, was a
vast improvement. However, second generation
units still experience damage from condensation.
Although the materials used in second generation
high efficiency boilers last considerably longer,
they still eventually succumb to corrosion.

THIRD GENERATION TECHNOLOGY

After two decades of trial-and-error, the boiler
industry has finally realized that high efficiency
and long product life can only be obtained by
preventing condensation from occurring in the
combustion chamber. Raypak’s Advanced Design
Boiler is the first of a new generation of boilers
that can obtain ultra-high efficiencies without
compromising product life. The “secret” to the
ADB’s longevity is that condensation occurs only
in a corrosion-resistant condensing heat exchanger.
The ADB is designed so that condensation will not
occur in the primary heat exchanger or the
combustion chamber. The result
is an ultra-high efficiency
product that lasts.

Welcome to the future
of boiler technology.

The Advanced Design Boiler is the first boiler that can
meet your exact efficiency requirements. The ADB, when
used without the Condensing Heat Exchanger (CHX), can
deliver thermal efficiencies up to 84%.

If higher efficiency is required, simply add the Condensing
Heat Exchanger to the installation. The CHX is designed to
capture the maximum amount of available energy by
extracting both sensible and latent heat from the flue
gases. That means ultra-high efficiencies – and substantial
energy savings.
