New Product
Aspen Firetube Boiler Line
The new Aspen and Aspen Light Commercial condensing
boilers are part of U.S. Boiler Company’s recently updated
high efficiency product line. The boilers feature a 10:1
turndown ratio, up to 96% AFUE, and low emissions.
With a stainless steel, vertical firetube heat exchanger,
the Aspen line includes seven sizes between 85 and 399
MBH, with a 155 MBH combi available. All sizes can be
wall- or floor-mounted. The Aspen (85-270 MBH) has
top and bottom supply/return/gas connections for flexibility
(non-combi models). The touch screen control on
the Aspen Light Commercial (320 and 399 MBH) can be
swapped with the boiler logo badge for optimal ergonomics
in wall-mount installations. The Light Commercial models
also come with both wall- and floor-mounting hardware
pre-installed.
Each model in the new Aspen line is equipped with
advanced Sage2.3 controls. Through the boiler control,
addition of Sage Zone Controls is simple. This provides
further energy savings, system optimization and shortcycle
prevention. In the Light Commercial models, the
Sage2.3 controls also make for simple lead/lag configuration
in multiple-boiler applications.
At higher elevations, Aspen series boilers require zero
or minimal
de-rating,
reducing the
cost of oversizing
the boiler.
A 3-in-1 vent
connection
and split voltage
junction
box with fused
connection
boards add
further versatility
and ease
of installation.
Also, the dimpled
firetube heat exchanger in the Aspen line provides
lower pressure drop than water-tube heat exchangers of
similar capacity.
Each boiler in the Aspen product line comes with an
outdoor reset and sensor, and is covered by a five-year
parts warranty. In all, U.S. Boiler now offers stainless
steel, condensing models from 80 to 800 MBH, with multiple
heat exchanger options and turndown ratios of 10:1
and 5:1.
