Strategic Alliance Advances Biomass Initiatives

Tri-Mer Corporation, a developer of advanced technologies for the control of NOx, fine particulate and industrial gases, and Enginuity Energy LLC, a renewable energy company and holder of patented Ecoremedy® gasification technology, have established a research agreement for the testing of biomass fuels at Enginuity Energy's research and development lab in Harrisburg, Pennsylvania.

The agreement gives Tri-Mer Corporation access to Enginuity Energy's robust Ecoremedy® gasification technology, which economically gasifies a wide range of extremely high moisture and high ash content material; Enginuity Energy LLC will have access to Tri-Mer's patented UltraCat catalyst filter system, which removes NOx, acid gases and particulate, also dioxins, in one system. The companies will conduct extensive air emission testing on a wide range of biomass fuels.

"We are extremely excited to be working with the technology leader in emissions control" said David Mooney, Enginuity Energy's Chairman and Chief Technology Officer. "With the addition of the UltraCat Technology to our already low emission gasifier, we will be able to guarantee our clients the cleanest emissions in the industry."

John Pardell, President of Tri-Mer Corporation, noted, "The incredibly fuel-versatile Ecoremedy® gasifier offers us a terrific opportunity to demonstrate the superior filtration capabilities of the UltraCat Filtration System on a wide variety of materials."

CERAMIC FIBER TECHNOLOGY FACILITATES
ADVANCEMENT IN HOT GAS FILTRATION

Tri-Mer Corporation, a developer of advanced technologies for the control of VOCs,
fine particulate and industrial gases, has introduced “UltraTemp Filtration,” a hot gas filtration
system that filters fine particulate to extremely low levels.  

The heart of the UltraTemp Hot Gas Filtration system is a new generation of ceramic filters.
Earlier generations of ceramic filters –sometimes called “candle” filters – were manufactured
from high-density granular powders similar to common ceramic products. While effective,
they were brittle, with low thermal shock resistance, and were prone to cracking and
breakage from thermal shock. As a further drawback, these older ceramic filters were
sometimes hard to keep clean under continuous operation.

Now, with advances in fiber and ceramic technology, these issues have been overcome.
The filters used in the Tri-Mer UltraTemp Filtration system are manufactured from a new
generation of low-density ceramic fibers that provide exceptionally high resistance to
thermal shock. This makes the filters very ductile and resistant to crack formation.

The unique composition of the ceramic fibers give the UltraTemp filters an exceptional ability
to capture fine particulates at the fiber surface, without blinding.  They are thus easy to clean
using standard pulse-jet techniques. Being fibrous, rather than granular, the filter elements
are also lightweight and very robust for installation and handling. They have high porosity with
low resistance to flow, which minimizes the number of elements required for a given application.

The UltraTemp Filtration system provides optimal filtration for gases between 400°F and 1000°F,
and in most cases can be applied to hot gas streams up to a maximum operating temperature
of 1650°F. Typical filtration results are 0.001 grain/dscf (2 mg/Nm3); many results are a fraction
of this typical value.

UltraTemp Filtration is compatible with heavy inlet loadings, often above 1 grain/ dscf 
(2300 mg/Nm3).  Certain applications involving three or four times this inlet loading still
achieve outlet levels of less the 0.001 grains/dscf. The ceramic filters are almost completely
chemically inert and highly corrosion-resistant.

Applications of the Tri-Mer UltraTemp Filtration system include glass production,
waste incineration,and biomass pyrolysis.  UltraTemp Filtration is also an excellent way
to achieve ICI boiler MACT compliance for coal, biomass, and wood. Other applications
include metal smelting, mineral processing and chemical production.

The Tri-Mer UltraTemp Filtration system features an option for dry injection of calcium or
sodium-based sorbents for the capture of acid gases. Injected in the duct upstream of the
filter modules, the additional sorbent particulate is easily captured along with its pollutant gas.
For these applications, SO2 removal is typically 80% or better, with removal efficiencies
as high as 97%. HCL removal is typically 95%, and often as high as 99%. 

If the need is NOx, VOC, or dioxin removal, UltraTemp filters elements are available with
catalysts embedded in the filters themselves. Urea is then injected upstream of the filters.  
NOx removal in these systems is typically above 90%.  VOC oxidation and dioxin removal
are also both exceptionally high. UltraTemp Filtration can incorporate both sorbent injection
and catalyst reduction in a single system. Acid gases, such as SO2, and NOx can be
simultaneously removed in the same system.

Tri-Mer’s UltraTemp Hot Gas Filtration system uses a baghouse configuration with a
reverse pulse-jet cleaning action. The filters are back-flushed with air, inert gas,
or other appropriate gases. It has a reliable sealing mechanism that is easy to access,
and the design has been engineered for easy installation and maintenance. Filter elements
are manufactured in various sizes, the largest of which is ten feet long and six inches in
diameter, including an integral mounting flange.

The UltraTemp Filtration system is an efficient, proven approach for hot gas filtration. 
With over 400 applications worldwide, it is now commercially available throughout the US,
with full technical and start-up support. 

Tri-Mer Corporation, a technology leader in air pollution control, is the exclusive
manufacturer of the UltraTemp Filtration system, and provides turnkey engineering,
manufacturing, installation, and service through its Michigan facility.

NEW FILTER TECHNOLOGY COMBINES HEPA-LIKE
PERFORMANCE, A MERV 16 RATING AND
SELF-CLEANING ADVANTAGE

Who benefits? companies that deal with fine particulate emissions, including:

  • Food and pharmaceutical manufacturers
  • Chemical processors
  • Manufacturers of textiles
  • Users of mining and tunneling equipment
  • Shops providing laser cutting or metal spraying
  • Manufacturers and users of powder coating systems

Tri-Mer Corp., a world leader in air pollution control systems and indoor air quality products,
has introduced Tri-Flow, a new filtration concept that delivers HEPA level performance with
a MERV 16 rating.

Tri-Flow Compact filters are a higher-performing alternative to bag, cartridge and pocket filters,
which are typically rated MERV 10-13. They have a small footprint, and an exceptionally large
filter surface area: Tri-Flow Compact filters provide 2-3 times more filtration compared to similarly
dimensioned bag (pocket) filters.  An even greater increase in filtration area vs. volume is
achieved in comparisons with sleeve-type high efficiency filters. 

The unique Tri-Flow design provides in-line pulse jet cleaning and maintains an exceptionally
low operating pressure drop. Filter efficiencies of 99.999% on 0.5 micron and larger particles
(by weight) are typical.

Tri-Flow Compact filters are self-supporting and are manufactured using proprietary filter media
tailored to the application. There are 7 filter media, including options for hydrophobic / oleophobic,
high temperature and anti-static applications. All media is pleated and continuously bonded for
maximum dimensional stability and filter integrity. A resilient mounting flange provides a dust
seal that prevents bypass.

Tri-Flow elements have a multi-year service life for virtually all industrial applications: compared
with conventional bag or cartridge-type filters, service life is 3-5 times longer, with zero compromise
of filter performance. Filter change-out is fast and "tool-free," and, notably, is done from outside the
collector, from the clean air plenum side. As a result, it is never necessary to enter the dirty air
plenum side for servicing, a feature which eliminates concerns about employee exposure to
hazardous dusts.

Existing dust collectors can often be adapted to accommodate Tri-Flow Compact filters.

Tri-Flow Compact Filter Systems, and Tri-Flow Environmental Control Booths, are manufactured
exclusively by Tri-Mer Corporation, Owosso, MI.  (989) 723-7838.

TRI-MER INTRODUCES ENVIRONMENTAL CONTROL
BOOTHS WITH HEPA LEVEL FILTER PERFORMANCE

The Tri-Flow Environmental Booth was designed to meet the 5 specific requirements
buyers say are most important for an environmental enclosure in an industrial setting:

  • Protection from Dust and Noise
  • Efficient Filter Performance
  • Simple Operation and Maintenance
  • Booth Design Flexibility
  • Low Life Cycle Cost

Tri-Mer Corporation, a world leader in air pollution control systems and indoor air quality
products, has introduced the Tri-Flow Environmental Control Booth.

Protection from Dust and Noise

The Tri-Flow Environmental Booth was designed for plant areas where dirty and/ or noisy tasks
need to be confined to their own workspace. The Tri-Flow Environmental Control Booth provides
HEPA level filtration performance and has a MERV 16 rating. It is 99.999% efficient on particles
0.5 micron and larger by weight. Perforated acoustical panels contain and absorb noise
generated inside the booth.

Efficient Filter Performance

Tri-Flow Environmental Booths provide reliable and consistent capture velocities at the booth
opening and throughout the booth. There is no air turbulence, no "hot spots," and no
uncomfortable drafts to interfere with operator productivity.

The capture velocity provided throughout the booth means that workers are not confined or
tied to a fixed work space, hood, hose, etc. Because the collector pulls in dust through a grille
that extends the full width of the booth, workers can freely perform tasks throughout the
workspace. Typical inlet velocities are generally in the range of 125-150 FPM.

Tri-Flow Booths operate at a significantly lower pressure drop than traditional cartridge filters.
This results in significantly lower energy consumption as well as longer filter life. Typically,
Tri-Flow filters have a productive service life 3-5 times that of conventional filters.

Simple Operation and Maintenance

Tri-Flow booths use low-speed, low-noise direct drive blowers that are an integral part of the
booth and power module.

A timer-controlled, automatic pulse jet cleaning system uses solenoid valves and blow-down
pipes to assure that the booth maintains its capture velocity by measuring filter pressure drop
and automatically cleaning the filters on demand. Filter access is easy, and change-out is
simple and "tool-free."

Booth Design Flexibility

Tri-Flow booths feature a smooth, ledge-free interior to minimize dust accumulation.
Each booth is custom-configured to suit the application, and can be expanded as facility
needs change. Overhead lighting is provided to suit the application as well.

The Tri-Flow Booth is also the only environmental booth that is customized to the facility.
A selection of 7 media options means there's an ideal solution for your application, whether
it involves electrostatics, fine dusts or fumes, high temperatures, or hydrophobic / oleophobic
particulate. All media is pleated and continuously bonded for maximum stability.

Low Life Cycle Cost

The Tri-Flow Environmental Booth provides manufacturing, process and job shop facilities
with an exceptionally efficient, new option for in-plant enclosures. It is the ideal choice for
companies who want to combine high filter efficiency - 99.999% on 0.5 micron and larger
particles (by weight) - with lowest life cycle cost.

The Tri-Flow Environmental Booth is ideal for metalworking processes, particularly welding,
plasma torch cutting, air arcing, sanding, grinding, chipping, and buffing. It is also highly effective
for isolating processes such as powder coating, mixing and polishing.

Tri-Flow Environmental Control Booths, and Tri-Flow Compact Filter Systems are manufactured
exclusively by Tri-Mer Corporation, Owosso, MI. (989) 723-7838.

TRI-MER INTRODUCES COST-EFFECTIVE
REACTIVE MERCURY SCRUBBER

Tri-Mer Corporation has introduced a technology that provides up to
99.9% reduction in mercury (Hg) emissions. 

Emissions from coal-fired power plants, municipal waste incinerators and gold mining
activities are the major contributors to mercury pollution in the U.S.

The new Tri-Mer scrubber design incorporates a simple wet chemistry process that
provides a cost-effective means of reducing all forms of mercury in emissions.  The novel
scrubber technology transforms mercury into mercuric sulfide,   a stable and manageable
form of mercury that can be disposed of as a non-hazardous waste. The superior efficiency
of the Tri-Mer scrubber is the result of a patent pending oxidation monitoring method,
which optimizes the system chemistry.

Tri-Mer developed the scrubber in conjunction with ADA Technologies, Inc., a research,
development and commercialization company based in Littleton, CO.  ADA, an industry
leader in mercury clean-up technology, developed the enabling chemistry for Tri-Mer
through an EPA grant. 

Research indicates that airborne mercury emissions are likely to travel long distances
before settling out of the air onto the earth hundreds of miles from the point of origin. 
Once in the environment, the mercury is transformed through biotic processes into highly
toxic organic forms, such as methyl mercury and dimethyl mercury, that accumulate
in the ecosystem. 

Humans are exposed to the toxic pollutant when they consume contaminated fish or other
wildlife that feed on the fish.  Serious neurological problems have been associated with
human exposure to high levels of mercury.   By reducing airborne mercury emissions,
Tri-Mer’s system aids in the effort to keep the food chain free from mercury and its toxic effects.

The scrubber systems are manufactured in UV-resistant white polypropylene, FRP,
Hastelloy, or PVDF.  Pilot testing is available.

CLOUD CHAMBER COLLECTS SUBMICRON PARTICULATE,
FROM COAL COMBUSTION AND INDUSTRIAL BOILERS,
REMOVES FUMES AND GASES

Tri-Mer Corporation has introduced the Cloud Chamber System, a technology that has proved
99%+ efficient for the collection of submicron particulate from sources such as coal combustion,
industrial boilers and diesel engines.

"CCS" is a wet scrubber technology that charges water and particulates with opposite polarity. 
In the action of the scrubber, droplets and particles move continuously in relation to each other. 
As they approach 20 microns of separation, induced electrical attraction pulls the particles into
the droplets.  Each droplet collects thousands of particles – coarse, fine, submicron, ultrafine and
condensables. This means that collector water droplets are delivered to the particulate in a way
that has not been achievable previously.

CCS offers several advantages over conventional control devices used with coal combustion,
industrial boilers and other sources.  One of the most important is the requirement of less than
1.5" w.g. of pressure drop under full load operation. (For comparison, conventional "Venturi"
systems typically require 40" to 70" of pressure drop; diffusion candles typically require 16" to 20"
of pressure drop.)  This factor is a major contributor to the system's low operating costs.
Also notable:  the CCS is applicable to both soluble and insoluble particulate, so it is
well suited for coal combustion and industrial boilers.

A second unique feature of the CCS is its ability to remove any gas treatable by a wet scrubber,
including HCl, NO2, SO2, Cl2, NH3 as well as HF, H2SO4, HNO3, ammonia and amine compounds,
at the same time as particulate.  This is important  because, for the first time, one device can handle
particulates and corrosive fumes simultaneously.

The CCS has been shown to be 99%+ efficient for the collection of all types of particulate
down to 0.1 micron.  Systems will be manufactured to customers' specifications in polypropylene,
FRP, PVC, stainless steel, and alloy materials.

TRI-MER INTRODUCES CHROME SCRUBBER

Tri-Mer Corporation has introduced C/E-1, a system which reliably and consistently removes hexavalent and trivalent chrome particulate without costly chemicals.

The all-mechanical system is the first of its kind.  It is 99%-99.9% efficient, regardless of input
loading, for typical hexavalent and trivalent chrome applications.  The system will also meet
the .006 mg/amp/hr emission rate.

C/E-1 has no internal moving parts to wear or replace, and continuously recovers collected
chrome from both the gas stream and the filter for convenient disposal.  Its unique dispersion
media filter is reusable indefinitely.

Water requirements for C/E-1 are low: average consumption is 15 gallons per hour in a
20,000 cfm unit.  Static pressure is less than 3" w.g. across the system.  C/E-1 is simple to install
and operate and is available in capacities to 60,000 cfm.  Originally engineered for anodizing
and plating lines, the system has proven highly effective for other types of fumes as well.

FUME SCRUBBER ACHIEVES 
MAXIMUM EFFICIENCY WITH
MINIMAL ENERGY CONSUMPTION

Fan / Separator from Tri-Mer Corporation is a high-performance, low-maintenance fume scrubber
that uses 90% less water, and 20% less brake horsepower than conventional wet mass transfer
scrubbers.  The result is lower waste volumes and lower utility costs.

Available in sizes from 50 cfm to 100,000 cfm, Tri-Mer's Fan / Separator eliminates a variety of
contaminants, including sulfuric acid, hydrochloric acid, plating chemicals, caustics and other
compounds used in metal finishing and chemical processing.

The intake fan and scrubber sections of the Fan / Separator are mated in a unique design,
acting as a centrifuge in the scrubbing process.  Acid gases are pulled into the eye of the fan
through the spray header, which is located across the inlet.  Fifty to sixty percent of the dilute
acid is centrifugally removed by the action of the fan; it then flows into a venturi drain for
discharge into the plant waste treatment or recirculation system.

Residual contaminants are eliminated during a secondary separation phase.  Scrubbed air
enters the expansion chamber, where its velocity is slowed and the air is impinged on
polypropylene tube filter packs, removing virtually all contaminants before the air leaves the unit.

Maintenance for the Fan/Separator is simple:  the rigid filter packs slide in and out easily for
cleaning as needed.  PVC or polypropylene construction is standard;  optional materials are
fiberglass-overlayed PVC, stainless steel and mild steel.  Other options include pH controls,
and variable frequency drives for air minimization during off times.

OIL MIST COLLECTOR
ELIMINATES REGULATORY WOES,
IMPROVES WORKPLACE ERGONOMICS

Tri-Mer Corporation has introduced the O/M-1 Mist Eliminator.  The system uses advanced 3-stage technology to achieve collection and elimination of mists.

Stage 1 substantially reduces mist loading to the final stage.  This stage uses an advanced
13-layer mesh filter media that's proprietary to Tri-Mer.  Operation is at 1 to 1-1/2" of pressure
across the unit; removal performance is 99%+ at 3 microns.

Stage 2 is the coalescing stage.  Its 16-layer filter achieves 99%+ efficiency at 2 microns.

Stage 3 uses six proprietary filter layers for final mist elimination.

O/M-1 is compatible with mineral oils, soluble oils and synthetics, and will accommodate
multiple mist sources.  It can be engineered to eliminate smoke and other aerosols
simultaneously with mists.

Features of the Tri-Mer O/M-1 include a low pressure design that minimizes energy consumption,
and gages at the first and second stages which monitor static pressures across the filter pads. 
Automatic wash-down cycle can then be activated; wash-down can also be initiated manually.

O/M-1 is a cost-effective alternative to centrifugal collectors, indexing fabric filters, and electrostatic precipitators.  It is easy to install (package includes duct connections, controls interfacing and fan,
plus recirculation, pump and piping where needed) and requires very little maintenance.  When
maintenance (such as filter cleaning) is needed, operation can continue uninterrupted.  The
system's filter cartridges can be removed, cleaned and restored to service in moments.

The link between exposure to coolant mists and disease in workers exposed to them is
well-documented.  By capturing these mists, worker health, safety and productivity can all
be improved.  In addition, the Tri-Mer O/M-1 will reduce the risk of fire from petroleum-based
lubricants, and offers the important ergonomic advantage of low noise operation.

Finally, O/M-1 exhausts very clean air back into the plant, thus it substantially reduces the
need for make-up air, and helps to keep heating and cooling costs low.

Tri-Mer's O/M-1 is available in ratings from 500 to 40,000 cfm (standard sizes) and up to 60,000.

SCRUBBER WITH INTEGRAL QUENCH
HAS WIDESPREAD APPLICATION

Tri-Mer Corporation has introduced a new technology for eliminating common inorganic flue gases, including SO2, HCl, HF, Cl2 and others, from combustion processes.

Called Q-Scrub, the scrubber is engineered for use with incinerators, rotary kilns, calcinators,
direct and indirect-fired ovens and all combustion processes that produce corrosive by-products. 
Where NOX control is required, Q-Scrub offers easy interface with Tri-Mer's Multi-Chem®
NOX scrubber.

Q-Scrub has an integral quench to cool gases up to 1800°F.  Materials of construction for the
quench section depend on inlet temperature and the compounds to be destroyed and include
Hastelloy, steel, and high-temperature fiberglass.

A variation of the design, Model QV, features a quench venturi engineered to handle particulate
(including submicron).  It meets U.S. standards for grains per dry standard cu. ft. (GR/DSCF).

Tri-Mer Q-Scrub systems are custom-engineered to individual user gas volume and
contaminant input/output loadings.  Systems include gas cooling section, vertical or horizontal
wet scrubber and fan, plus chemical feed package.  Options include chemical monitoring,
process logic controls and motor control center.

Q-Scrub accommodates from 350 to 450,000 acfm.

TRI-MER INTRODUCES HIGH-PERFORMANCE 
RANDOM-DUMP PACKING MEDIA

Tri-Mer Corporation has introduced Tri-Packs, a tower packing media for air pollution control towers. 
Tri-Packs features a unique spherical design which facilitates maximum surface contact between the
gas and the scrubbing liquid with minimum pressure drop.  This greatly lowers the horsepower
required of the blowers.  Because they have no "corners" or "valleys," Tri-Packs eliminate puddling,
prevent clogging of the system and eliminate the need to backflush, a common requirement for
other packing media.

Tri-Packs creates a steady, consistent "rain" through the column, rather than a "flood." 
This allows the use of smaller pumps with less horsepower.

Tri-Packs are manufactured in a variety of plastics, including polypropylene and PVDF. 
Tri-Packs are lightweight and will not settle under any operating conditions.  They are usable
in columns of all sizes, both new and retrofit.

NEW PACKED BED SYSTEM CONTROLS 
26 COMMON EMISSIONS

Tri-Mer Corporation has introduced a new packed bed technology for the control of 26 common industrial pollutants.

Tri-Mer "VF" Series Packed Bed Scrubbers provide continuous control of common industrial
gas emissions, most notably NOX, CL2, and SO2.  Also controlled are common acid fumes,
including H2SO4, HCL, NO3, and HF.

Tri-Mer "Vertical Flow" packed scrubbers are particularly appropriate where gas streams have
extreme high or low pH.  These scrubbers are very well-suited for use as primary or secondary
systems in crossflow or countercurrent modes, and can also used in a series where there are
gas streams with multiple contaminants.

The "VF" series scrubbers combine intensive gas/liquid mixing and low pressure drop, thus the
system is able to perform at high efficiencies (typically 98% to 99.9%, based on mass emission
number, inlet vs. outlet) using minimal energy.  Tri-Packs, a spherical packing that has a very
low static pressure per foot of depth, is the standard packing media.  This combination of features
helps to minimize both the size of the tower and the volume of scrubbing liquid that's required.

Tri-Mer's "VF" system is engineered to several configurations accommodate various plant space requirements.  Most designs incorporate the exhaust blower into the packed bed tower as a
unified vertical structure.  Systems can be custom-manufactured with capacities from 390 cfm to
100,530 cfm, and are a practical alternative for the largest facilities as well as small job shops.

Materials of construction include polypropylene, PVC, FRP, high alloy metals.  Tri-Mer also
manufactures dual-laminate structures which layer fiberglass-reinforced plastic over PVC. 
VF systems are supplied with process control packages for fully-automated operation, and
monitoring equipment as specified by the customer.

NEW DUST COLLECTOR 
MAKES SHUT-DOWNS OBSOLETE! 

Tri-Mer Corporation has introduced the Whirl Wet dust collector.  The system is manufactured
from 100% high-strength polypropylene, which makes it corrosion-proof, structurally strong,
easy to clean, and resistant to mechanical damage.  Most importantly, the system allows the
removal of collected particulate, plus virtually all other maintenance procedures, without
shut-down of the system.

Whirl Wet is suitable for both soluble and insoluble particulate larger than three microns. 
This includes explosive dusts, all powdered chemicals, food dusts, metals machining, corrosive
dusts, sticky particulate and hygroscopic dusts that often cause agglomeration or blinding
of bag collectors.

The Whirl Wet has a smooth interior and encased structure, which satisfies the requirements
of food/beverage and pharmaceutical processing.  Cleaning and sludge drag-out are both
automated: drag-out is accomplished with a modular drawer assembly that slides into and
out of the unit's side.

Whirl Wet uses very little water, and produces significantly less sludge volumes than
conventional wet collectors.  It operates without pumps, complex plumbing or internal moving
parts.  A PLC monitors static pressure across the unit, and total flow through the unit; it will
also maintain system water temperature where required for sanitation purposes.  An automatic
washdown feature is available; other options include airflow monitoring, and
temperature monitoring.

Whirl Wet is available in capacities from 500 to 50,000 cfm.  Systems can be engineered to
return air to the plant for maximum HVAC efficiency.

TRI-MER BLOWERS ARE NEW ALTERNATIVE
FOR CORROSIVE APPLICATIONS

Tri-Mer Corp has introduced a new centrifugal blower for air handling and exhaust applications. 
Tri-Mer Blowers feature solid polypropylene housings, so corrosion-resistance is highest, and there
is no risk of delamination (a common problem with fiberglass and other layered materials). 
Impellers blower units are backwardly-inclined, non-overloading design.

Vibration and noise are both very low, and silencers are not required to meet OSHA standards.

Blower units are available in Belt Drive and Direct drive configurations and are well-suited to
HVAC applications, and for use with air scrubbers, metal treatment and chemical processing
equipment.  They are an excellent replacement blower where traditional blowers have
deteriorated from exposure to acids or other corrosive fumes.  Units can be piped in parallel
for high air volume applications.

Blowers operate at temperatures up to 180°F and pressures to 12" PSIG.  Capacities are
100 cfm to 100,000 cfm.  Units are available with variable frequency drives.  The units are
engineered for easy retrofitting; applications assistance is available.
