Harsco introduces its P-K SONIC boiler, which contains an innovative stainless-steel heat exchanger design with segments designed to work together to help optimize efficiency and improve reliability. Its patented DUET Technology design allows the P-K SONIC boiler to operate up to 96% efficiency with ultra-low emissions. It also is up to 60% smaller than the traditional boilers, making retrofits easy and, in most cases, with no special rigging required.
