Lochinvar 454 1 Dépliant
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
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.
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
NOx emissions requirements. An independent
certification laboratory test gave us a rating of
less than 20 ppm - corrected to 3% O
2
. And less
NOx means a cleaner environment.

Enhanced to Provide Performance and Serviceability
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.
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.
