1、Lochinvar first introduced Copper-Fin technology to the boiler industry some 50 years ago. Since then, weve 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 mat
2、erials.Installation Flexibility and Cost-SavingsWith 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 cant provide. Plus, thanks to special insulating materials, Copper-Fin un
3、its require only 3” clearance from combustible walls. Whats 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 t
4、o 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 erThe Lochinvar Copper-Fin boiler design uses a two pass heat ex chang er. Water is circulated through a row of high ly-efficient, fin
5、ned 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 fr
6、om 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 DesignWhats more, advanced casting processes allowed Lochinvar to develop a unique one-
7、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 StandardsBecause of our unique fan-assisted combustion process, the Copper-Fin exc
8、eeds todays toughest NOx emissions requirements. An independent certification laboratory test gave us a rating of less than 20 ppm - corrected to 3% O2. And less NOx means a cleaner environment.Energy Efficient, Cost Effective BoilersCopper-FinCommercial GasBoilersEnhanced to Provide Performance and
9、 ServiceabilityOur 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 o
10、f 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 re
11、duces 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
