PEBCO® recently introduced the patent-pending, Self-Contained Dustless Loading System, or SCDLS, a system featuring both a dust collector and a loading spout in a fully integrated housing for loading dry, dusty materials into trucks and railcars. Previously, PEBCO®’s standard integral dust collector (IDC) had an overall height of ~46” and the competitors’ measure approximately 32”. This limited the installation of integral dust collectors in existing loading systems that did not have a dust collection feature, but was looking to add it. The dust collection feature on PEBCO®’s SCDLS-22 adds only 20 ½” to the overall equipment stack-up, making it possible to replace almost any existing loading system with a PEBCO® SCDLS. In new projects, the reduced height also reduces the costs associated with steel structure and material transport systems. The SCDLS was developed in collaboration with Donaldson/Torit. Other features of the SCDLS include: • Environmentally-responsible loading of dry, dusty materials • Innovative, and low profile • Industry minimum overall height • Field replacement possible for almost any existing loading system that does not currently include a dust collection feature • Power Core Filter cartridges available in conventional and static dissipating • Donaldson/Torit’s proprietary Power Core filter media and pulse system • Dust collection cartridges easily replaced through side access panels with no special tools required • All wear components are bolt in for ease of replacement

1. A Detailed Review

4.  Fan Assembly
 Inlet
 Receiver
 Blow Down Valves
 Electrical Box

5.  The inlet can be
constructed of
different materials
depending on the
product’s
 abrasiveness,
 corrosiveness,
-or-
 temperature.

6.  The receivers store
compressed air that is
used in the cleaning
cycle of filter
cartridges.

7.  Goyen Brand
 Pilot operated
 High volume, short
duration blast of air

8.  Standard port, 1” npt

9.  Ability to use air
pressure gauge to
confirm adequate air
pressure for blowing
material from the
cartridges.
 Designed for
minimum of 60 psi,
preferred 80 psi.

10.  Connection Hose
between receivers.
 Only 1 plant air
connection is
required, because
receivers are
connected through
this hose

11.  3” W.C. for cleaning
pulse
 5” W.C. for cartridge
replacement
 Truck loading is
normally based on
timing sequences.

12.  Fan Assembly pulls air
up through the
annulus and in
through the cartridges
so only clean air
travels through the
fan assembly.

13.  The damper regulates
flow through the
collector, adjusting
the damper increases
or reduces the air flow
to provide optimal
dust control by the
SCDLS.

14. Optimal performance is defined as:
 minimal dust is pulled into the cartridge while no
dust escapes into the atmosphere
-and-
 capturing the dust but not capturing the product.
If loading low density, small particles, shutting the
damper reduces the potential to pull too much air
through the cartridge, capturing the product.

17.  Single wrap radius
ensures consistent
pull between all three
pulleys for even
raising and lowering
of the spout.

18.  Connection for “dirty
air” differential
pressure switch.

19.  Chain drives RLS
 Stops the
motor/reducer when
the chute is either
fully retracted or fully
extended, limits the
up and down travel.

20.  Contact block opens
circuits and stops at
adjusted settings.
 Adjusts points on the
rotary limit switch.

21.  Second,
adjust the
up travel
(with the
left) or
down travel
(with the
right) until
it clicks.
 First,
loosen the
set screw.
 Last,
retighten
the set
screw.

22.  Slack Cable
Limit Switch
is used to
limit the
extended
position of
the spout.

23.  Cable Captivator
 Senses when the
cables go slack
and stops the
down travel of
the spout.

27.  Remove Butterfly Nuts
 Easy Pull Handles

29.  Clean air
inlet for fan
assembly.

30.  The blow
down
valves are
designed
to blow air
onto the
exact spot
of the
cartridge
for
optimal
cleaning.

31.  Air filter

32.  Simply remove wing
nuts and lift off.

37.  Inlet
 Shroud
 Cones

39.  DC Power Supply
 Micro PLC
 Custom Controls
 Terminal Strips
 Pulse Control
to control timing between
or duration of blow down
pulse for consistent filter
cleaning
 Pilot Valves
to open blow down valves
for pulsing/cleaning
