| Built for long life with little
maintenance, Vigilante Fuel Oil Preheaters employ a
tube-in-tube coil bundle design, constructed with seamless
shells and heavy, cast iron heads. Combined with copper
outer tubes, carbon steel inner tubes, precision machined
gasket surfaces, and fully expanded tube depth, this design
assures efficient, dependable performance.
The Vigilante comes with an exclusive safety feature to
prevent costly mishaps. If this unit begins to fail, a
built-in sight glass changes color the moment leaking oil
mixes with the surrounding heat transfer fluid. The
discoloration catches the operator's eye, eliminating oil
return to the boiler and preventing costly contamination of
the heating system.
