SHIELD and ARMOR High Efficiency Water Heaters

Increase operating profit with our high-efficiency water heaters

ARMOR and SHIELD commercial water heaters deliver best-in-class innovation from Lochinvar. They operate at 96% thermal efficiency, with inputs up to 500,000 Btu/hr, and provides a 100% effective defense against a water heater's worst enemy-lime scale buildup inside the tank.

ARMOR and SHIELD uses the industry's most advanced stainless steel heat transfer system. Sealed combustion technology delivers a quiet and environmentally friendly supply of heat to the system. Plus, with drawdown capacity as much as 15% higher than typical tank-type heaters, you get more usable hot water than any other competing models.

The result is quiet, long-lasting green performance.life cycle efficiency that keeps saving money, year after year.

Long-Lasting Life Cycle Efficiency

High-efficiency tank-type water heaters have one thing that ARMOR and SHIELD does not, energy-robbing lime scale buildup. This insulates the water from the heat source, decreasing thermal efficiency, which increases operating costs. Additionally, the rate of scaling increases with temperature and usage. Just a ¼" of lime scale buildup will cause increased fuel consumption and raise operating costs as much as 25%. Lime scale buildup also requires periodic acid washes in the tank that will simply result in a shorter useful life of the equipment.

Because ARMOR and SHIELD have no flue tubes inside the tank, the impact of lime scale is eliminated, ensuring high efficiency and low operating costs throughout its life cycle.

Advanced Electronic Control

ARMOR and SHIELD feature the ultimate water heater control which makes system setup, service and operation a breeze. A 2-line, 16-character backlit LCD display gives readouts of setup, system status and diagnostic information in words, not codes. SMART CONTROL also includes:

• Night Setback
• Time Clock
• Alarm Contacts
• Runtime Contacts
• Service Mode
• Last 10 Lock-Outs

Multi-Unit Installations

The outstanding life cycle efficiency and performance of ARMOR and SHIELD can serve the highest demand applications through manifolded installation of multiple units. For example, five SNA500 units will provide total storage of 625 gallons with a total maximum input of 2.5 million Btu/hr.
