Lochinvar, an industry leader in high-efficiency boiler and water heater technology, today announced the expansion of its commercial gas water heater family with the most durable and powerful SHIELD™ models yet. Available in standard and ASME construction, the models now range from 125,000 to 500,000 Btu/hr and offer up to 96 percent thermal efficiency.
“The recent SHIELD upgrades mark new strides in engineering. Our research and development teams have been working hard to design a new system that will boast even better efficient technology,” said David George, Lochinvar product manager. “With the highest durability built into every SHIELD commercial gas water heater, facility managers and contractors can count on solid performance and reliability for projects ranging from multi-family developments to universities.”
The SHIELD product family is designed to minimize lime scale buildup in the tank and on heating surfaces. By controlling and creating high water velocity through the heat exchanger, lime scale buildup is reduced, and the heating surfaces and tank are kept clean, so thermal efficiency remains high for the life of the product.
Designed for a variety of commercial applications, the newly upgraded SHIELD models feature a fully modulating burner with a 5:1 turndown ratio. The new design can fire as low as 20 percent of maximum input when water heating demand is lowest and increases to 100 percent for peak demand periods. This results in better overall efficiency and less cycling compared to “on-off” tank-type units that only fire at 100 percent.
The new models also offer multiple connectivity platforms with optional CON•X•US®, MODBUS® and BACNET™ modules. Lochinvar’s CON•X•US remote connectivity platform gives commercial facility managers and building owners the ability to monitor and adjust equipment controls from a mobile app. The MODBUS and BACNET capabilities allow building managers to monitor and manage the units through their local building management systems.
These models feature Lochinvar’s advanced SMART CONTROL™ System, providing a bright, backlit LCD display with soft-key buttons and a wide variety of advanced control functions, including readouts of setup, system status and diagnostic information.
All utility and water connections are located at the top of the appliance to reduce equipment room footprint and increase installation flexibility.
The SHIELD family now features 10 models, ranging from 125,000 to 500,000 Btu/hr. For more information about the SHIELD product line, visit www.Lochinvar.com.
