5:1 Firing Rate Turndown
Package with Lock-Temp Tank

Separate Tank for Flexibility, Lower Replacement Costs

With standard tank-type water heaters, your choices are limited when it comes to matching input with storage capacity to meet “peak demand” delivery requirements. With ARMOR, you can match one or more water heaters with inputs ranging from 150,000 to 800,000 with one or more storage tanks in a wide variety of sizes. Lochinvar Lock-Temp® tanks are available to meet the need, from our 80-gallon vertical to the 5000-gallon vertical or horizontal model.

Another advantage of the ARMOR “dual component” system is lower replacement costs. Standard tank-type designs require replacement of the entire water heater. With ARMOR, you’ll save time and money by only replacing individual components as needed, such as the pump or storage tank.

Fully Modulating with 5:1 Turndown

ARMOR is equipped with fully modulating combustion with 5:1 turndown. This means ARMOR can fire as low as 20% of maximum input when water heating demand is lowest, and increase the firing rate up to 100% as demand increases. The result is better overall efficiency and less cycling, compared to tank-type units which are “on-off,” which means they can only fire at 100% of maximum input.

Stainless Steel Condensing Heat Exchanger

The ARMOR’s stainless steel heat exchanger is built to ASME Section IV requirements. Its design provides superior resistance to corrosion caused by condensation from low entering water temperatures. Non – Condensing commercial water heaters will fail early with low entering water temperatures; however, with the ARMOR the lower the supply water temperature the more efficiently it performs throughout the life of the heater.

Direct Venting Up to 100 Feet

ARMOR offers 7 venting options and tremendous flexibility for placement of units within the building, because it permits directvent air intake and exhaust runs up to 100 equivalent feet using either PVC, CPVC, Polypropylene or AL29-4C stainless steel vent pipe. Intake and exhaust runs can terminate horizontally through a sidewall or vertically through the roof.
