THREE PASS DESIGN
WEIL-MCLAIN PROVEN TECHNOLOGY
Weil-McLain has been using a three pass design concept
for over 70 years because it provides better flame control,
and more ecient fuel utilization, which reduces heating
costs. The Ultra Oil has incorporated finite element
modeling to enhance overall boiler operation.
■
Computer designed flueway fins increase the heat transfer surface
area, which extracts more heat and increases eciency without
penalizing boiler back pressure
■
The wider flueways decrease the negative impact of fouling
■
An added benefit of the three pass design is the horizontal
configuration, which makes virtually all of the combustion chamber,
turnaround, and flueways visible from the front of the boiler for
easy cleaning and maintenance
■
Silicone coated fiberglass rope insures a positive seal
■
Revolutionary rear section design directs the flue gas flow into the
flueways without sacrificing pressure drop through the inner and
the outer flueways which eliminates rear refractory
CAPTURED SEALS-OVER 45 YEARS OF
RELIABLE PERFORMANCE
Boiler sections will expand and contract as they heat
and cool. Our captured seal allows the cast iron to
move while preventing leaks, unlike rigid metal push
nipples. The flexible elastomer sealing rings guarantee
a watertight seal while the precision-machined port
grooves secure them in place, and protect them from
the contaminants of the water.
