BLOWDOWN SEPARATORS (see page 14)
• For models SSB12-48 PN BDT-ASME36
• For models SSB60-180 PN BDT-ASME42
A separator accepts the flash steam and effluent
from the boiler blowdown and reduces the tempera-
ture and pressure to insure a safe discharge of water
and sludge. Steam flash and pressure are absorbed
and pass harmlessly to the outside via a vent. The
separator design utilizes a water seal at the outlet,
which permits the operator to introduce cold water
from the bottom to mix with the hot water and boil-
er steam in the blowdown separator. This reduces
outlet temperature to a safe discharge level.
These separators require specific plumbing from the
boiler blowdown valve and require connection to a
cold water supply. (If the separator is less than half
full of water after the boiler is blown down cold
water must be added to bring the water level to the
halfway mark before the next blowdown).
• 0-30 PSIG pressure gauge; 0-200F temperature
gauge; water sight gauge glass and valve set assem-
bly are included.
CONTROL VOLTAGE STEPDOWN
TRANSFORMER
• Provides 120 Volt (220 Volt export) from main power
supply. Factory wired and fused.
MULTISTAGE LOAD PROGRESSIVE
SEQUENCERS
Accurate control is provided by automatic progressive
sequencing in the use of energy and minimizing wear on
electrical components. The sequencers are designed to
apply power progressively to larger KW boilers. A factory
installed pressure sensitive sequential control reacting to
steam boiler pressure progressive energizes or de-ener-
gizes heating elements through power contactors. A
delay between sequencer steps before start-up and
between each subsequent step eliminates power surges.
Each sequencer is matched and factory pre- set to boiler
system requirements. Electronic progressive sequencers
give accurate control of multi-stage loads of the type
used in steam boilers. Features include progressive
sequencing (first on- first off) that equalizes the operat-
ing time of each load. Integral solid-state light emitting
diodes show active stages. Should a power interruption
occur, all elements are instantly de-energized for safety.
Upon resumption of power the control will re-stage the
loads one at a time.
