Lochinvar unveils the Next Generation of Copper-Fin II Commercial Gas Water Heaters


by Lochinvar | 06/20/2008

Lochinvar Corporation is proud to announce the introduction of the next generation of Copper-Fin II commercial gas water heaters, models 401-751. All four models -- 401, 501, 651, 751 -- offer all the features of the original Copper-Fin II line, plus proportional firing systems, multiple venting options, and extremely low NOx ratings. The 401-751 water heater models boast 85% thermal efficiency ratings, which means 85 cents out of every fuel dollar are used to heat water. And while conventional water heaters achieve peak efficiency only while running at maximum capacity, the Copper-Fin II models consistently provide peak performance, even while operating at low outputs.

All this is due to the models' proportional firing systems. The proportional firing system provides a measured response to demand -- as much or as little as needed -- while always maintaining the ideal gas/air ratio. Multiple gas valves supply the burners in firing stages depending on the amount of heated water required. Meanwhile, multiple blowers maintain the proper airflow to ensure the most efficient combustion at each level of use. A Honeywell T775 controller allows the heater's system to digitally monitor the hot water demand and automatically adjust the blower output and gas valves to meet the required demand. As the demand is met, the system shuts down gradually, turning off gas valves and reducing combustion air intake in direct proportion.

Like the original Copper Fin II line, the 401-751 models utilize Lochinvar's proven copper-finned heat exchanger. The gasket-free and slide-out heat exchanger employs intertwined copper-fin tubes which increase the heat transfer ratio 9:1 over plain copper tubing. Moreover, the new models also have extremely low NOx emissions. The fan-assisted combustion process discharges an extremely low rating of 9.9 ppm. The 401-751 models feature a wide variety of venting options, including conventional, sidewall, vertical direct-aire, horizontal/vertical direct-aire, horizontal direct-aire with fan, and outdoor venting. The flue sizes remain unchanged from the original
Copper-Fin II line, however, the flue outlets are now in the top left corner.

All four 401-751 models offer great flexibility and ease of installation. Because of their high efficiency, these units are compact enough to fit through standard 36" doorways intact. Once inside, the space-saving designs leave more room in the mechanical room. And the optional Multi-Stack® frame enables you to put two units in the space normally required for one. Lochinvar Corporation is a leading manufacturer of high-efficiency water heaters and boilers, ranging in capacity from small residential units to three-million-plus BTU models. Based in Nashville, Tenn., with facilities in Detroit, Mich., Tampa, Fla., Dallas, Tex., and Philadelphia, PA., Lochinvar stocks equipment at all locations. ###
