Multiple Boilers for More Efficient Operation
The Constellation is made of 2 or more modules
allowing the option to step-fire individual modules with an outdoor reset
control according to the changing outdoor conditions and heating load. By
utilizing this type control, only the modules necessary to meet the heating
demand of the day need to burn fuel. Most competitors commercial boilers are
all "on" or all "off" wasting energy and fuel dollars on mild degree-days.
Cast-Iron Sections and Push Nipples
The Constellation system utilizes cast-iron
construction in each boiler because of its durability and efficient heat
transfer capabilities. Cast iron sections and push nipples are utilized to
construct the heat exchanger. Using only the highest quality cast-iron and heat
transfer designs, the Constellation will provide many years of efficient and
trouble-free operation. And since multiple cast-iron heat exchangers are
utilized, a total system shutdown is avoided because each module can operate
independently and be serviced when necessary without effecting system
operation.
Installation Flexibility
The Constellation system can be customized to fit specific job requirements
with multi-module flexibility and a compact unit size. Unlike massive one piece
commercial boiler heat exchangers, individual modules are preassembled and are
only 22"x 32" making them easy to install and fit through small doorways
eliminating any building modifications.
Easy Access and Maintenance
A sturdy cast-iron swing door allows for quick
and easy inspection of the oil burner and combustion area while extra large
flueways allow for easy cleaning and set-ups. These flue way openings are
easily accessed through an integrated two part draft hood. In addition, a
recessed target wall increases the chamber size and is protected from
accidental flue brush damage during normal maintenance. All components are easy
to reach, greatly reducing the time spent on regular maintenance and service
calls.
Factory Pre-Wired & Tested
Each Constellation Boiler is shipped with
controls pre-wired and is subjected to a series of rigorous quality assurance
tests to provide quick and easy setup in the field.
