Gaylord RSPC-ESP User Manual

MODEL “RSPC-ESP”

POLLUTION CONTROL UNIT

GENERAL SPECIFICATIONS AND DESCRIPTION

GENERAL: Furnish one (1) Gaylord ClearAir™ Pollution Control Unit
model number RSPC-ESP-_____ as manufactured by Gaylord Industries
of Tualatin, Oregon in accordance with the following:

The pollution control unit shall consist of a smoke control section, odor
control section (optional) and exhaust fan section (optional) all built into
a common base as an integral unit. Smoke control shall be accomplished
by electrostatic precipitation (ESP). The unit shall be ETL listed to UL
867 and UL 710 and labeled.

SMOKE CONTROL SECTION: The smoke control section shall contain
one or more electrostatic precipitator (ESP) cells to remove smoke
particles from the air stream to a level no higher than 20% opacity when
operated in accordance with the operation and maintenance guidelines.
The ESP cells shall be of a floating plate design to eliminate plate warpage
during high heat operation. Each cell shall have nine (9) tungsten
wires run perpendicular to the air flow which will ionize the air stream.
Spike type systems shall not be accepted. The cells shall be positioned
on slide tracks so that they may be easily removed through a hinged
cell access door(s). For ease of handling, individual cells shall weigh
less than 54 lbs. There shall be removable, cleanable debris screens
located immediately upstream of the ESP cells and a moisture separator
immediately downstream. An electrical panel mounted on the unit shall
contain the high voltage power pack assembly, safety disconnect switch,
main disconnect switch, fuses and a magnetic starter for the exhaust
fan when fan is included. The safety disconnect switch shall interface
with the electrical panel access door such that when opened it will shut
off service to the power pack(s) and ground them to drain the residual
electrical charge from both the power pack(s) and ESP cells. The ESP
cell access door shall interface with the electrical panel access door so
that it cannot be opened without first opening the electrical panel access
door. The high voltage power pack(s) shall be self-limiting type and shall
be self-contained. The electrical panel shall include indicating lights to
monitor cell and transformer voltage. The main disconnect switch for the
exhaust fan and control circuits shall lock the electrical panel access
door closed when in the “on” position. The unit shall contain one or more
oscillating wash manifold(s) with “Conserva-Clean” spray nozzles to wash
the ESP cells with hot detergent injected water each time the exhaust fan
is shut off. Maximum required wash pressure is not to exceed 30 PSI
at 140°F. Maximum water flow rate per cell is not to exceed 2.3 GPM.

CONTROL CABINETS: EXPLANATORY NOTE REGARDING
CONTROL CABINETS: There are multiple arrangements of controls

for the operation of exhaust hoods and the ClearAir™ Unit. In the one
arrangement, the Control Cabinet in the kitchen serves both the exhaust
hood and the ClearAir™ Unit. In an alternate arrangement, there is a
Control Cabinet for the exhaust hood electrically interfaced with a Sub
Panel that serves the ClearAir™ Unit. In both arrangements the Exhaust
Fan, ESP, Wash Cycles and Fire Cycle functions are controlled by the
main control cabinet. The difference between the two is the location of
the plumbing components.

1. Main Control Cabinet Only - This arrangement is typically used
when the ClearAir™ Unit is located on the roof or mechanical room
immediately above or within 50’ of the control cabinet.

2. Main Control Cabinet and Sub Panel Combination - This arrangement
is typically used in the following situations: (a) when the ClearAir™ Unit
is located in a mechanical room away from the exhaust hood or (b) when
it is impractical to inter-connect the hot water lines between the main
control cabinet and the ClearAir™ Unit or (c) when there is insufficient
