Automatic
Bottom Blowdown Timer SwitchBoiler blow down
is mandatory. A boiler cannot continue operating for
very long wihtout expelling the left behind solids as steam
is generated. Periodic blow down must take place. This can
be accomplished with the addition of an automatic blowdown
assembly. A boiler that is blown down regularly will
maintain high efficiency and last longer. (The use of an
automatic device should not preclude periodic visual
examination of the boiler blow down effluent to examine that
the automatic assembly is working as intended.) Selection
is based upon the boiler's drain connection as noted on the
selection chart below. Each assembly is factory piped and
wired, and includes a ball shutoff valve, ball by-pass
valve, motor driven ball valve, and NEMA 1 panel containing
the interval timer.
