Expanding on its line of ARMOR commercial water heaters, Lochinvar introduces two new ARMOR wall-mount models. Available with inputs of 125,000 and 199,999 Btu/hr., the new ARMOR wall-mounts offer up to 96% thermal efficiency with 5:1 turndown and compact designs that fit the tightest installations. ARMOR features stainless-steel heat-exchanger technology with modulating/condensing combustion and superior energy efficiency. The new models are equipped with the advanced SMART SYSTEM operating control, which includes a built-in cascading sequencer that allows for water heaters with different Btu/hr. to be installed together to maximize turndown capability.
