SHN/SGN Series Electrostatic Precipitator

Description

THE TIME-PROVEN ANSWER TO INDUSTRIAL FUME PROBLEMS

The most effective electrostatic precipitator (ESP) on the market today is the genuine Smog-Hog® SHN/SGN Series, manufactured exclusively by Parker Hannifin. No other ESP unit can match this system’s efficiency, effectiveness and long-term cost savings for the collection of oil smoke and coolant mist.

For more than 50 years, Parker has invested in constant improvement of electrostatic precipitator technology. And, the Smog-Hog SHN/SGN Series is made up of the most advanced ESP units available—better than electrostatic units of the past and superior to every alternative mist collection system.

APPLICATIONS

Engineered to perform long-term, heavy-duty industrial air cleaning, SHN/SGN units eliminate smoke, mist and dust generated by a variety of applications—brazing, casting, flame cutting, drilling, grinding, milling, screw machining and more. Also, these sytems are available in a variety of sizes and versatile configurations to fit your company’s needs. SHN/SGN units are equipped with airflow capacities ranging from 400 to 9,000 CFM. Systems can be ducted, unducted, free hanging and machine-mounted, depending on your specific application — eliminating the need to give up valuable floor space in your facility!

COMMON APPLICATIONS

• Brazing     • Casting     • Cold forming     • Flame cutting     • Forging     • Gear cutting     • Heat treating     

• Induction heating     • Lathes     • Plastic and rubber forming     • Quenching     • Screw machining     

• Soldering     • Threading     • Vacuum pumps     • Welding     • Wet grinding     • Wire drawing

ENSURE EMPLOYEE SAFETY WHILE MINIMIZING COSTS

SHN/SGN mist collectors keep employees healthy and on the job by removing dangerous airborne contaminants that can cause respiratory problems. These powerful units eliminate dirty airborne particles before they settle on floors, land on expensive machinery or are inhaled—situations that can lead to accidents, workers’ compensation claims, OSHA compliance violations and expensive machine repairs.

Investing in the SHN/SGN Series can also improve your company’s profitability by reducing energy and housekeeping costs. These systems recirculate air into your plant and reduce exhaust air make-up requirements with efficiencies up to 99%. Thousands of gallons of valuable resources such as cutting oils, lubricants, coolants and plasticizers are recycled each year by Parker SHN/SGN Series customers.

Continuous Cleaning

SHN/SGN units can be programmed to run continuously during and between shifts. This feature reduces the energy resources needed to power the system every day, as well as decreases the potential for contaminants to accumulate while the SHN/SGN system is in the “off” mode.

PRODUCT ENHANCEMENTS REDUCE COSTS

Parker Mist-Stop filter dramatically reduces the amount of mist and smoke particles that pass through the Ionizer and ESP Collection Component. So, less time and money is spent servicing and cleaning a unit, because intervals between cleanings increase up to two to three times longer! The Mist-Stop filter is composed of heavy-duty aluminum mesh and a high-efficiency coalescing pad.

Another product enhancement is the expanded SHN cabinet design (pictured below). Now standard on all SHN units, the larger cabinet allows room for the 1” aluminum mesh filter and optional 2” Mist-Stop filter— eliminating the need to add an inlet plenum. Mist-Stop filters are available for use on all SHN and SGN units that use an impingement plenum, as well as expanded SHN systems.

How ESP Works

SHN/SGN mist collectors are configured using ESP technology—a proven concept and technology in use for over 50 years. By electronically charging both large and microscopic contaminants, these systems capture impurities like a magnet in collection cells. At the same time, recyclable coolants and oil are collected for reuse, and safe, breathable air is discharged back into the workplace.

WHAT MAKES THE SGN/SHN BEST IN CLASS

• Reusable ESP collection components eliminate costly filter replacements and disposal.
• Flexible installation options accommodate many application requirements including lack of floor space.
• Low energy consumptions can help increase company profitability.
• Contaminants drain off ESP collection component, reducing the frequency of unit maintenance and cleaning.
• Units maintain consistent airflow at all times for continuous clean air circulation.
• Low sound levels eliminate the need for expensive silencers.

COMPETITIVE UNITS

CARTRIDGE COLLECTORS

• Low-efficiency cartridges clog with contaminants, reducing airflow.
• Smoke applications require frequent and expensive replacement of HEPA filters.
• Large unit size takes up valuable floor space.
• Expensive, non-standard size filter replacement.
• High energy consumption

BAG FILTER UNITS

• Standard HVAC-grade ASHRAE-rate pocket bag filters have low efficiency on mist and smoke particles.
• Bags load with oil, clog and drain poorly.
• Frequent and expensive filter replacement.
• Potential for solid hazardous waste disposal costs.

CENTRIFUGAL MIST COLLECTORS

• Large droplets cause unit imbalance and frequent maintenance.
• Smoke particles too small for centrifuge are returned to work environment.
• Vibration transmitted to machine tool can cause loss of precision and quality problems.

MEDIA MIST COLLECTORS

• Low-efficiency cartridges quickly fill up and minimize airflow.
• High energy consumption.
• Expensive filter replacement.
• Possible expenses needed for solid waste disposal.

SHN OR SGN?

All SHN and SGN units use the same electrostatic precipitator technology to clean industrial mist and oil smoke. Both systems are available in a variety of sizes and configurations depending upon your company’s application. However, there are a few differences to consider when choosing the right ESP mist collector.

Ambient Solutions

Cleaning ambient factory air is a viable solution when capturing contaminants at the source or via a machine mount method is impractical. Parker Hannifin ambient systems offer a flexible industrial filtration solution for complex manufacturing processes. Common applications for ambient mist collector solutions include facilities with overhead cranes, process configurations which prohibit direct source capture and instances where facilities and/or processes have variable contaminant generation points.

Ambient systems work by achieving a targeted number of air changes in the containment area. The number of air changes required is based on contaminant properties, generation rates, and acceptable concentration levels.

Airflow patterns are developed by strategically locating hoods or SmogHog mist collection units throughout the containment area to entrain the airborne contaminants and mix the air. The clean air exhausted from the system can be used to further develop circulation patterns to enhance contaminant capture. Both the inlet and outlet airflow directions are configurable and systems are available for wall, ceiling or rooftop installation to provide a customized solution to meet a variety of facility and process needs.

Ambient systems offer operational cost savings by recirculating clean air, avoiding exhausting conditioned air and minimizing make-up air needs.

SmogHog systems available in an ambient configuration include the SHN Series and SGN Series
