Lochinvar - Natural Gas ASME
The Copper-Fin², is 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 Lochinvar’s added an 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 89% thermal efficiency. This means that 89¢ out of every fuel dollar goes into heating the water, 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 pressure.
Space Saving, Service Friendly Design
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.
The SMART SYSTEM™
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 anddiagnostic information
