Lochinvar has expanded its ARMOR commercial condensing water heater product line with models that range from 1.25 to 4.0 million Btu/h. They are available in indoor or outdoor construction and offer 98 percent thermal efficiency. These stainless steel-constructed models offer an enhanced low-profile, horizontal heat exchanger, which is heavier, more robust and offers easy access to the combustion system. The advanced 316L water tube design enhances flow delivering performance and reliability for large commercial applications. They come standard with the CON•X•US remote connectivity platform with SMART TOUCH control. The 8-inch touch screen and multicolor interface make setup and navigation of parameters easy. As many as eight heaters can be cascaded together for redundancy, providing peace of mind without third-party controls or complex logic programming. 615-889-8900; www.lochinvar.com.
