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 upgraded SHIELD models feature a fully modulating burner with a 5:1 turndown ratio. The 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.

These 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 SMART CONTROL System, providing a backlit LCD display with soft-key buttons and a variety of 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. Read for more information about the SHIELD product line.
