Laser Cut Precision
A CNC laser uses Programmable Logic Controls to precisely cut the Squire Indirect Water
Heater’s tank shell out of 14 gauge 316L stainless steel to a tolerance of .01 inch.

The Squire Stainless Steel Indirect Water Heater -- with 12 models to choose
from in capacities from 30-119 gallons, we are sure to have the right size
indirect water heater to fit your application.
Squire features important enhancements that our customers will recognize and
benefit from such as a welded and passivated stainless steel tank and heat
exchanger, two-inch thick, high-density insulating foam, and best of all it is
designed, engineered and assembled in America.

Passivated for Protection
- a new Class of Water Heater
Tank Cylinder Roller
The computer controlled tank cylinder rolling machine ensures that the 316L stainless
steel is transformed into a geometrically perfect cylinder.
Coil Winder
Straight tubes are rolled by a seven axis coil winder and turned into a precise, round
coil used in the indirect water heater to transfer the BTU’s from the heat source to the
potable water stored in the tank.
Robotic Welder
This state of the art six axis programmable robotic welder uses computer guidance to
accurately weld the stainless steel fittings to the tank.
Hydrostatic Leak Test
After welding, the tank is hydrostatically pressure tested to ensure quality
conformance.
Passivation Process
Each tank is subjected to a soaking spray of
nitric acid. This treatment washes away any
iron that was left behind during the welding
process and re-establishes the oxide level of the
stainless steel to ensure corrosion resistance.
By removing iron from the welded surfaces, the
Squire is less susceptible to corrosion brought
on by aggressive water.
Jacket and Foam
The dent resistant polypropylene jacket and
ABS caps are attached to the tank assembly,
and then high density foam is added using a
high pressure dispensing system to provide
insulation that will keep the heat where it
belongs, in the water. The result is a tank that
is jacketed and evenly foam insulated with
standby losses as low as 0.5°F per hour.
