RELIABILITY > IRON ADVANTAGE OVER OTHER MATERIALS
Even though the boiler is relatively low mass, the KN Series has ~20% of the energy density (btu/in3) of a modern copper boiler of equivalent input. The iron also has 5x the wall thickness of a typical copper heat exchanger tube. These characteristics reduce the sensitivity to flow and scaling. In order to survive the high energy density and sensitivity to scaling, copper boilers need to operate at and maintain high water velocities. This results in high pressure drop and possible erosion of the copper exchanger. LOW PRESSURE DROP The KN Series boiler, not requiring high velocities, has a relatively low pressure drop of2.4 Ft. H2O at a flow of 100 gal./min. (Cv=100). While low, this Cv is sufficient to allow good flow balancing when multiple boilers are connected in reverse return. |
