Harsco Industrial Patterson-Kelley Hydronic High Efficiency Boilers


Patterson-Kelley’s highly efficient MACH & SONIC condensing boilers are universal and suitable for condensing, non-condensing, and combination systems. CSA certified up to 96% efficiency with actual net thermal efficiencies up to 99%, P-K condensing boilers represent a commitment to green technology and innovation. The ultra-high efficiency of P-K boilers helps reduce fuel bills by as much as 80%.

Miura LX Series High Efficiency Boiler


The Miura LX Series boilers require 50% less floor space than typical firetube boilers and do not require tube pull space. This allows for double capacity or a reduction of space requirements in the case of new construction. Miura’s compact design means much smaller radiation losses and larger fuel savings, which provide standard high-pressure steam efficiencies of 85-87%, with available NOx ratings as low as 9 ppm.
