START WITH A
SOLID FOUNDATION
750K BTU Copper-Fin Low NOx Heater
THE FOUNDATION OF LOCHINVAR BECOMES STRONGER
Copper-finned tube, non-condensing appliances are the foundation of
Lochinvar’s success. In 1993, Lochinvar introduced the Copper-Fin², the first
horizontal chassis, copper-finned tube pool heater to operate with fan-
assisted combustion. Now, the Copper-Fin² is even better. Along with high
thermal efficiency, gasketless heat exchangers and multiple venting options
we have added Lochinvar’s exclusive SMART SYSTEM™ control.
Eight models from 500,000 to 2,070,000 Btu/hr input provide you with
exceptional products with a long list of new features in addition to the
established features that redefined the industry. The Copper-Fin² was the
first proportional fired, fan assisted pool heater on the market. Every model
features a small footprint for easy passage through a 36” door, low NOx –
third party tested to less than 20 PPM, Stack Frames that can put twice the
Btu/hr input in the same space and vent diameters up to 8” smaller than
conventional atmospheric pool heaters.
THERMAL EFFICIENCY
Copper-Fin² pool heaters offer a remarkably high thermal efficiency, dramatically reducing the operating cost of the equipment. Copper-Fin² achieves this efficiency through the combination of an advanced fan assisted combustion system and a gasketless heat exchanger. The heat energy from the combustion process is transferred to the water as it passes through the copper finned tube heat exchanger. The sealed combustion design of the Copper- Fin² eliminates external heat losses, this means the energy dollars heat the water, not the mechanical room.
GASKETLESS HEAT EXCHANGER
In 1989, Lochinvar was the first manufacturer to offer gasketless copper- finned tube heat exchangers. Our unique gasketless design enhances reliability by eliminating o-rings and gaskets found on other brands. The heat exchanger features glass lined headers and copper-finned tubes with extruded integral fins spaced 7 fins per inch for exceptional heat transfer. The heat exchanger is built to ASME construction standards for 160 psi working ressure and is backed by a five year warranty.
SPACE SAVING, SERVICE FRIENDLY DESIGN
Our enhanced Copper-Fin² models offer the same reliable operation in a new
service friendly design. The gas inlet, internal controls and Building
Management connections have been repositioned to the front of the appliance
for easier service and simpler installation. The built-in air filter reduces
maintenance and improves performance with a field convertible option to
install the air intake on the rear or the right side of the pool heater. In
addition, Lochinvar was the first manufacturer to offer factory welded Stack
Frames that allow you to put two pool heaters in the space for one.
MULTIPLE VENTING OPTIONS
The Copper-Fin² offers eight venting options to meet the most challenging installation requirements. The Copper-Fin² can vent vertically in Category I with double wall “B” vent or horizontally in Category IV with AL29-4C stainless steel vent material. Vent termination can be Rooftop or Sidewall with combustion air drawn naturally from the equipment room or via dedicated air intake piping. And if floor space is limited, the Copper-Fin² pool heater can be installed outdoors with an optional Outdoor Vent Cap. HIGH EFFICIENCY COMMERCIAL POOL HEATERS
REFINED DESIGN PUTS MORE CONTROL AND INFORMATION AT YOUR FINGERTIPS
The most exciting addition to the Copper-Fin² is the SMART SYSTEM™ control.
The SMART SYSTEM is an advanced, state of the art integrated operating
control. We introduced the SMART SYSTEM control in 2005 and it has delivered
proven operation in thousands of demanding commercial applications. The
control provides the installer, owners and operators with precise temperature
control and diagnostic information.
ADVANCED FEATURES INCLUDE:
- 2-Line, 16 Character LCD display of Setup, System Status and Diagnostic Data in Words, not codes
- Built-in Cascade sequencer controlling up to 8 Pool Heaters
- Modbus protocol – optional
PROPORTIONAL FIRING
Proportional firing divides a single manifold of multiple burners into
smaller, independent stages.
With up to four stages of individual operation, the Smart System control can
reduce the firing rate down to approximately 25% Btu/hr input. This simple
but effective design matches the pool heater’s firing capacity to the heat
loss of the pool or spa. Full fire or On/Off combustion systems often fire
the entire gas train in short, inefficient bursts. Stage firing delivers the
Btu’s required in smoother and longer burn cycles which will improve
operation and reduce component fatigue.
AUTOMATIC PUMPED BYPASS
All Copper-Fin² pool heaters are equipped with an automatic pumped bypass
ensuring proper flow and return water temperatures to the heat exchanger
resulting in longer life and trouble free operation.
The automatic pumped bypass is provided as standard equipment in a horizontal
configuration. A vertical configuration* is also available offering the
flexibility to meet mechanical room space requirements or piping constraints.
