Lochinvar first introduced Copper-Fin technology to the boiler industry
some 50 years ago. Since then, we’ve continued to refine and perfect
it - adding advanced fan-assisted combustion, hot
surface ignition, a unique gasketless cop per finned tube heat
ex chang er and highly efficient insulating materials.
INSTALLATION FLEXIBILITY AND COST-SAVINGS
With compact sizes that use less floor space than ever before,
all Copper-Fin units are narrow enough to fit through a standard
36” doorway – an ad van tage most commercial boilers can’t provide.
Plus, thanks to special insulating materials, Copper-Fin units require
only 3” clearance from combustible walls. What’s more, our
Stack Frame allows you to install two units in the area
normally required for one. This makes it easier to fit multiple Copper-
Fin boilers into cramped me chan i cal rooms. And you can even use a
smaller diameter vent stack - up to 8” smaller than typically required
for comparable atmospheric boilers - so it saves money as well as
valuable mechanical room space.
UNIQUE COPPER-FIN HEAT EX CHANG ER
The Lochinvar Copper-Fin boiler design uses a two pass heat
ex chang er. Water is circulated through a row of high ly-efficient,
finned copper tubes. The high rate of water flow creates
a scour ing action that prevents sed i ment and lime-
scale buildup, common in conventional boilers,
and the finned copper tubes allow maximum
heat transfer efficiency. To create this
special heat transfer capability,
Lochinvar extrudes the fins from
thick wall copper tubing to
precise specifications - ex act-
ly 7 fins per inch. The result
is an integrally-finned tube
with a heat transfer ratio 9
times greater than a plain copper tube.
HEAVY-DUTY GASKETLESS DESIGN
What’s more, advanced casting processes allowed Lochinvar to
develop a unique one-piece header system. This gasketless design
provides enhanced reliability, improved durability and optimum
performance - without the problems or failures common with
O-rings and gaskets.
MEETS THE TOUGHEST AIR QUALITY STANDARDS
Because of our unique fan-assisted combustion process, the Copper-
Fin exceeds today’s toughest NO
x
emissions requirements. An
independent certification laboratory test gave us a rating of less
than 20 ppm - corrected to 3% O
2
. And less NO
x
means a cleaner
environment.
ENERGY EFFICIENT, COST EFFECTIVE BOILERS
Our enhanced Copper-Fin models offer the same reliable operation, and
feature a more service friendly design. The down stream test valves and
referenced gas valves are now in the upper deck for easier access, and
the electrical and BMS connections have been repositioned to the front
of the unit for easier installation.
The gas valves, which are referenced to the sealed combustion chamber,
improve operational performance by monitoring the pressure in the
sealed combustion chamber and adjusting gas flow to maintain the
optimum air/fuel mixture.
And the built-in air inlet filter
reduces maintenance and
improves performance by
trapping dust and airborne
particulates that can foul the
burners and blowers.
With dual sight glasses (one
on each end), you can easily
monitor burner performance
and flame characteristics
throughout the entire
combustion chamber.
The operator interface panel
provides two-stage electronic
temperature control and
comprehensive diagnostic
status without opening the
control panel. Its user
friendly design simplifies
service while providing
additional diagnostic
information through a
series of LEDs.
