Model 75 Technology Overview
During operation, the contaminated air
to be cleaned passes across Trion's unique spiked ionizer blades
which are supported between flat grounded electrodes.
Revolutionary to the industry, the blades are made of stainless
steel that will not rust or break, thus eliminating costly
maintenance time and replacement costs.
The DC voltage supplied to the blades
creates a high intensity field where the particulate matter in the
air becomes electrically charged. The charged particles then
pass into a collector plate section made up of a series of equally
spaced parallel plates. Each alternate plate is charged with
the same polarity as the particles, which repel, while the
interleaving plates are grounded, which attract and collect.
Periodically, depending on the type and
amount, the contaminate is washed into the cabinet drain basin by an
automatic activated integral washing system that is located on both
the upstream and downstream sides of the ionizing-collecting cell(s).
A programmable logic controller (PLC)
and dual solid-state Pulse Width Modulated (PWM) high voltage DC
power supply are housed in a remote-mounted NEMA 12 enclosure.
The PLC controls the system functions of wash, fire suppression, and
fan on/off. A 7-day clock is standard. The PWM power
supply, which energizes the ionizing-collecting cells, comes
standard with LED indicator lights. Optional door-mounted
meters, which aid in determining cell operating status, are also
available.
In applications requiring extremely high
collection efficiency and low resistance to air flow, two or three
electro-static sections may be placed inline to create a double or
triple pass unit.
Durable Compact Cabinetry
When you invest in a Trion
Model 75 you want it not only to fit your unique needs, but your
individual space as well.
And you want it to last. Trion
housings are constructed using 16-gauge zinc-coated steel.
Then all welds and the finished area of welds are treated with a
corrosion and rust-inhibiting coating to assure long life.
Cabinet finish is completed with a durable industrial grade
semi-gloss, baked-on enamel no less than 3 mil thick. All
doors are gasketed to prevent air and water leakage. Finally,
the housing is furnished completely assembled for easy shipment and
installation.
Prefilter/Impinger
The prefilter/impinger track is a standard integral part of the
Model 75 ESP cabinet. A 2" rail is positioned upstream of the
ESP collector cell to accommodate a standard 40% free area
perforated panel for even air distribution, a metal mesh prefilter
for light oil mist, or an impinger for more heavy, fluid or
semi-fluid particulate matter. The particulate matter may
range in viscosities from that of water to relatively heavy grease.
In heavy loading applications, the liquid particles strike the
impinger, coalesce into droplets and then flow to the drain pan
below. If the particles are of a high viscosity nature that do
not readily flow into the pan, they are periodically flushed down
the drain with an optional bolt on collar containing an integral
wash system located upstream of the impinger. A similar track,
located downstream of the unit, is designed to house a perforated
panel and functions as an air distribution device as well as a
safety screen like its upstream counterpart.
The Electrostatic Air Cleaner Section
Electrostatic Air Cleaner Section enables extremely small
particulate matter, "The Fines," to be removed from an air stream
with relatively no resistance to air flow. This is due to the
open area of the collecting elements. The low resistance is
maintained from the start to the completion of the collection cycle.
The unit operated in the higher efficiency collection range, upward
of 95% DOP Method, on particles ranging in size from 10 Microns down
to 0.01 Microns in size.
Standard Blower Package
The TEFC energy efficient blower is designed for horizontal air
flow and mates with the air purification system to provide a uniform
distribution of air. The blower wheel is steel, backward
inclined, welded construction.
Optional UpBlast Blower
The NFPA 96 UpBlast fan is designed to mate with the air
purification system and provide uniform air distribution. It
is a centrifugal UpBlast exhaust fan, with drain, in compliance with
UL 762 for kitchen exhaust applications containing grease-laden air.
The blower wheel is steel, backward inclined, welded construction.
Side Access Filter Housing
The flexibility of the Media section provides and efficient
means for high efficiency filtration, as a prefilter or after
filter, depending on your requirement. This section is
designed to house a variety of mechanical filters that may be
required in your application. The housing allows for various
filter combinations that are tailored to your specific needs, such
as HEPAs, 95% bags, mini-pleated cartridges or other media.
The heavy-gauge dual-access housings are supplied with
industrial-grade hardware.
Side Access/Final Filter Section
Unlike particulate filters, odors in the form of undesirable
gases and vapors are most commonly removed from the air stream by
the process of adsorption that is enhanced by multi-faceted porous
surfaces of certain materials. Filter trays of activated
carbon or optional potassium permanganate pellets effectively
facilitate the adsorption of these odors and gaseous contaminates.
