Raypak’s Next Generation Condensing
Modulating Heater
Time-honored technologies unite with cutting-edge advancements in
Raypak’s new XTherm
ா modulating vertical heater. Never before has
a vertical heater provided both the installer and building owner such
installation flexibility, ease-of-commissioning, reliability and long-term
performance. Small space, not a problem. The XTherm has one of the
smallest installed footprints of any vertical condensing heater. Our
compact design makes it the perfect choice for those hard to reach
retrofit projects. Raypak’s XTherm is built with commercial-grade
components and materials. From our steel channel base to our stain-
less steel flue wrapper, and secondary heat exchanger, you can tell
the XTherm is built to last. It’s easy to handle and install, but still
user friendly to service. Now is the perfect time to take a closer look
at Raypak.
Flexibility
Industry-leading vent length allowances afford greater vent location
options, thus reducing wasted space. Vent versatility is further
enhanced by the self-tuning combustion system which compensates
for unusual chimney and vent configurations.
Category IV -CSA-certified 96% efficiency at full fire for hydronic boil-
ers and 97% for domestic hot water heaters
(Up to 99% at part
load!) When the job requires high efficiency, XTherm meets your
needs.
At the heart of every Raypak XTherm is a unique integral evaporator
system - the first defense against condensation in the primary heat
exchanger. Raypak’s evaporator system collects and re-evaporates
condensate which may form during initial start-up.
True Modulation
Modulation is nothing new to Raypak, we have honed our gas modu-
lation experience for over 50 years. The Raypak XTherm will precisely
track the heating load with it’s built-in TempTracker Mod control,
eliminating costly overshooting. Utilizing the latest European technol-
ogy for the combustion-components, the optimum fuel-air ratio is
maintained throughout the entire range of the load-tracking opera-
tion. Our smooth 4:1 turndown ensures efficiency is maintained
throughout the firing rate and actually increases during part load,
right when you want it! The XTherm automatically self-tunes to
accommodate the widest range of gas supply pressures. The high
quality integrated blower-gas valve is self-correcting and allows
smooth operation with fluctuating gas supply pressures. The Raypak
XTherm is cutting edge technology with atmospheric simplicity
