VACUUM BREAKER SYSTEMS
• For model ES boilers P/N ES89369
• For model SSB boilers P/N SSB89369
A vacuum breaker will prevent a boiler from flooding as a result of the steam condensing internally and creating a
vacuum after boiler shutdown. The breaker allows air to enter the boiler shell breaking the vacuum. This system is
a must for boilers connected to a condensate return tank. The vacuum breaker consists of a spring-loaded disc and
associated piping and is factory plumbed to the boiler. The SSB89369 is of stainless steel construction.
AUTOMATIC BLOWDOWN SYSTEM
• Extends life of boiler
• Saves labor costs
• Starts the boiler automatically every day
• Shuts down the boiler every day
• Automatically blows down the boiler every day
• Completely programmable, can skip days, different start and shutdown times, different operational durations.
• ES81600 for all model boilers.
A stainless steel, motor driven straight-through, self-cleaning ball valve with Teflon seats handles particles and dirty
fluid without the use of an up-stream strainer or other cleaning device. A timer (Standard analog time clock is set
for two hour time intervals, optional digital time clock can be programmed to one minute intervals.) and electronic
time delay relay control the boiler and the blowdown valve. A pilot light indicates when the blowdown valve is
open. The valve shall be plumbed to a proper drain or receptacle. An automatic blowdown system can be installed
on any boiler, regardless of size operating pressure or operating duty cycle.
BLOWDOWN SEPARATORS
(see page 18)
• For models ES12-48 and SSB12-48 p/n BDT-ASME36
• For models ES60-180 and SSB60-180 p/n BDT-ASME42
A separator accepts the flash steam and effluent from the boiler blowdown and reduces the temperature and pres-
sure 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 intro-
duce cold water from the bottom to mix with the hot water and boiler 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 assembly 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 operating 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.
