Product Overview

FULLY MODULATING WITH 5:1 TURNDOWN
ARMOR features advanced Negative Regulation (Neg/Reg) sealed combustion
technology, permitting fan speed to constantly adjust the volume of fuel and air
entering the burner. This ensures that ARMOR can safely and reliably operate with supply gas
pressure as low as 4 inches water column.
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 all other tank-type units which are “on-off,”which means they can only
fire at 100% of maximum input.
STAINLESS STEEL CONDENSING HEAT EXCHANGER
The stainless steel design provides superior resistance to corrosion caused by condensation from low
entering water temperatures. Traditional 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.
In Lochinvar’s stainless steel, condensing Armor product family, the Armor Wall Mount offers an effective
space saving solution. The Armor Wall Mount is available in two sizes, 125,000 and 199,000 Btu/hr input.
The light weight but powerful water heaters hang on any wall to give you more free space in your mechanical
room.
The water heater and tank combination is the heart of Lochinvar‘s “BETTER IDEA” water heating philosophy. The
ARMOR water heater is always installed with a separate storage tank to provide an effective water heating package
for commercial domestic water systems. The industry has made a few unsuccessful attempts at applying
residential instantaneous water heating to commercial applications. Instantaneous products are outmatched by
the faster, larger and variable hot water demands of a commercial application. Storage is essential to supply the
water to a system at a variety of speeds and volumes.
THE “BETTER IDEA” SYSTEM AND
INSTANTANEOUS WATER HEATERS
A STAINLESS STEEL STORAGE TANK
A WALL MOUNTED WATER HEATER
Available in 60, 80 and 119 gallon capacities, Lochinvar’s Lock-Temp Stainless Steel storage tank
makes a perfect companion to the Armor Floor Mount and Wall Mount water heaters. 14 gauge
316L stainless is formed, cut and fully welded into a light weight tank.
The stainless steel is “passivated” with a nitric acid treatment to re-establish the oxide level of
the metal after welding and to ensure corrosion resistance. The tank is finished with a dent
resistant polypropylene jacket and high density expanded foam insulation rated to exceed
ASHRAE Energy Efficiency Standards for standby losses. Lochinvar backs its Stainless Steel
Storage Tank with a 10 year limited warranty.
