The factory timing calibration is set at 0.2 of the second pulse duration and an interval time of 15 seconds between each filter pulse. Under heavy and prolonged use it may be necessary to modify these parameters, this decision is usually determined if the efficiency of the booth begins to diminish and re-programming by Siemens P.L.C. must be done only after consultation with EMS Powder Coating Machinery.

Under normal working conditions, the cylinder cartridge filters have a minimum 1-year life span, replacement filters are kept in stock at EMS Powder Coating Machinery and replacement is facilitated by a 12 mm nut on the underside of each filter.

The filter should be blown with a hand air gun once each week with care taken to clean the top of the filters, an area the automatic cleaning seems to miss. The optimum pressure required by the self-cleaning mechanism is 60 – 90 P.S.I., however, this may be lowered to a minimum of 30 P.S.I. if notice restraint is a factor.

The pulsing will be noticeably quieter at this level, but the cleaning is not as comprehensive. To assist in cleaning in this situation it is advisable to run the machine at a higher pressure, say 90 P.S.I., for a period of 15 minutes at a convenient time. If wet paint is used the life of the cartridge filters will be reduced. Only spray within the confines of the booth. Check the sealing of the filters on a regular basis.

If the powder is escaping through the booth, the cartridge filters are not sealing correctly. Due to having to use high-pressure centrifugal fans to obtain the necessary airflow of 0.7m per second per 1m, the noise level determines that ear defenders are required.

The spray booths manufactured by EMS Powder Coating Machinery are tested in airflow in the following ways: A hand-held anemometer is used to take readings at a distance of 400mm from the face of the booth and at intervals of 300mm longitudinally. The combined total is then divided by the number of readings. The suction force equals an average of 0.7 per second or above.

Important Notes

The anemometer readings will vary over the face of the booth. The performance will drop when the filters become resistive. Due to the high airflow and the high pressure required necessitating centrifugal fans with forwarding curved impellers, the resultant noise level will mean that ear defenders are required. It is strongly advised that our patented automatic switching device is used. Tests in production indicate that over 60% of the time suction is not required, our switching device switches off the fans when the gun is in the holster, thus saving operating costs.

A Small powder coating booth with recovery are cost-effective finishing environment for small-batch powder applications and powder coating systems. Featuring a primary and redundant filtration system, EMS Powder Coating Equipment’s powder coating booths capture high volumes of powder overspray with even small powder sizes for powder sprays that go to waste. This is a big plus in comparison to booths for wet paint. Batch powder coating booths are ideal, especially for small parts such as alloy wheels

The open-front design saves floor space and allows for easy transportation in and out of the booth.

The function of the Powder Coating Booth

The booth function is characterized by the protection of the coating process from external influences, combined with keeping the area around the booth is clean. The booth function is based on a powerful exhaust air system, which aspirates air from the booth interior through filter cartridges.

The resulting negative pressure produces an airflow from the outside of the booth to the inside, thus preventing powder from escaping into the environment. In order to have a full understanding of the booth operation, the booth functions are individually described in the following sections.

Exhaust Air System of the Powder Coating Booth in a Manual Powder Coating Line

The exhaust fan of the exhaust system is located in the fan housing above the filter cartridges. It sucks air from the booth interior through the filter cartridges and returns the clean air through the filter pads to the environment. The filter pads in the fan housing are intended for visual inspection only. Should one of the filter cartridges become damaged or develop a leak, the powder will be deposited on this filter stage.

The efficiency of the exhaust system depends on how severely the filter cartridge is clogged. For this reason, the suction efficiency is determined and indicated by measuring the differential pressure between the clean air side and the booth environment (pressure monitoring). A pressure rise means an increasing clogging of the filter cartridges.

Filter Cleaning

Filter cleaning is the process of removing dirt, debris, and other contaminants from a filter to restore its efficiency and extend its lifespan. Filters are used in a wide variety of applications, including air filtration, water filtration, and fuel filtration. When a filter becomes clogged with contaminants, it can no longer effectively perform its function. This can lead to a number of problems, such as reduced airflow, increased pressure drop, and contamination of the filtered medium.

There are a number of different methods that can be used to clean filters. The most appropriate method will depend on the type of filter and the type of contaminants that are present. Here are a few of the most common methods:

1. Manual cleaning: This is the simplest and most cost-effective method of filter cleaning. It involves physically removing the filter from its housing and then brushing, washing, or vacuuming the contaminants off the filter media.
2. Backwashing: This method is commonly used to clean water filters. It involves reversing the flow of water through the filter, which helps to dislodge contaminants from the filter media.
3. Sonication: This method uses sound waves to create vibrations that can dislodge contaminants from the filter media. It is often used to clean filters that are difficult to clean by other methods, such as filters with small pores or filters that are made of delicate materials.
4. Chemical cleaning: This method involves using chemicals to dissolve or break down contaminants on the filter media. It is often used to clean filters that are contaminated with oily or greasy substances.
5. Regeneration: This method is used to clean activated carbon filters. It involves passing hot steam through the filter, which removes the contaminants that have been adsorbed onto the activated carbon.

The frequency with which a filter needs to be cleaned will depend on the type of filter, the operating conditions, and the level of contamination. As a general rule of thumb, filters should be cleaned when the pressure drop across the filter increases by 25% or more.

Here are some tips for cleaning filters:

• Follow the manufacturer’s instructions: The manufacturer of your filter will provide specific instructions on how to clean it safely and effectively.
• Wear gloves and eye protection: When cleaning filters, it is important to wear gloves and eye protection to protect yourself from contaminants and chemicals.
• Clean filters in a well-ventilated area: Some cleaning methods can generate fumes, so it is important to clean filters in a well-ventilated area.
• Dispose of contaminants properly: Dispose of contaminants properly after cleaning filters. Do not dispose of contaminants in a way that could harm the environment.

By following these tips, you can ensure that your filters are clean and that they are performing their function properly.

Each filter cartridge is equipped with a cleaning device and can be cleaned while the booth is in operation. The cleaning procedure is activated manually by the relevant switch on the control cabinet.

The cartridges are cleaned by compressed air impulses and injected by pressure pipes inside the cartridges. The powder drops onto the booth floor, from where it arrives into the powder trolley or the powder collector.

The filter cleaning air is supplied from the pressure tank in the exhaust air
unit and must amount 5 bar (recommended), and not exceed 6 bar. The cleaning process and consequently the blow-off duration per filter cartridge and the pause time, before the next cartridge is blown off, are controlled by an electronic control unit. The blow-off time for the cleaning impulse must amount to 10-30 ms and is preset by the factory:

• Blow-off time = 20 milisecs (factory setting)
• Pause time = 10 s (factory setting)

Powder Circuit

In the context of powder coating, a powder circuit is a closed-loop system that transports and recirculates powder during the coating process. It consists of several components that work together to ensure efficient and consistent powder application.

Key Components of a Powder Circuit:

1. Powder Feeder: The powder feeder is responsible for metering the powder from the storage hopper into the powder circuit. It typically uses a rotating auger or a vibrating plate to deliver a controlled amount of powder.
2. Powder Conveying System: The powder conveying system transports the powder from the powder feeder to the application gun. It typically uses a combination of air pressure and vacuum to move the powder through a network of tubes and hoses.
3. Powder Delivery Hose: The powder delivery hose connects the powder conveying system to the application gun. It is designed to minimize friction and ensure a smooth flow of powder to the gun nozzle.
4. Powder Application Gun: The powder application gun is the device that applies the powder to the object being coated. It typically uses electrostatic charge to attract the powder particles to the grounded object, ensuring even and consistent coverage.
5. Powder Recovery System: The powder recovery system collects overspray, which is the excess powder that does not adhere to the coated object. It typically uses filters to capture the powder particles and then returns them to the powder feeder for reuse.

Benefits of Using a Powder Circuit:

1. Efficient Powder Utilization: Powder circuits minimize powder waste by recirculating overspray, reducing the need for fresh powder and lowering overall costs.
2. Consistent Powder Application: Powder circuits ensure consistent powder application by delivering a controlled amount of powder at a constant rate, minimizing variations in coating thickness.
3. Improved Work Environment: Powder circuits help to maintain a clean and controlled work environment by capturing overspray and reducing the risk of powder dust contamination.

7. Electronics Manufacturing: Coating circuit boards and electronic components with conductive or insulating powder coatings.

A powder trolley is a prerequisite for working with a closed powder circuit. In the closed powder circuit, the gun is connected to the powder trolley. The powder is fed from the powder trolley via the gun to the workpiece. The over-sprayed powder drops to the booth floor or is retained by the
filter cartridges, from where it also drops down inside the booth when the filters are blown off. The powder is scraped manually into the powder trolley, where it can be reused for coating operation.

Powder Trolley

A powder trolley, also known as a powder cart or powder transfer cart, is a mobile unit used to transport and store powder coating material. It is a versatile and essential tool for powder coating operations, providing efficient powder handling and contributing to a safe and organized workspace.

Key Components of a Powder Trolley:

1. Powder Hopper: The powder hopper is the main storage container for the powder coating material. It is typically made of durable materials such as stainless steel or polyethylene and is designed to hold a specific amount of powder.
2. Powder Discharging System: The powder discharging system allows for controlled release of powder from the hopper. It typically consists of a valve, a dispensing nozzle, and a hose connection.
3. Grounding System: The grounding system ensures that the trolley is electrically grounded to prevent static buildup and potential sparks during powder handling.
4. Mobile Frame and Wheels: The mobile frame and wheels provide maneuverability for transporting the trolley around the powder coating workspace. The frame is typically made of sturdy metal, and the wheels are designed for smooth rolling and stability.
5. Safety Features: Safety features may include brakes to prevent unintended movement, spill containment trays to catch powder leaks, and warning signs to indicate potential hazards.

Benefits of Using a Powder Trolley:

1. Efficient Powder Handling: Powder trolleys facilitate efficient powder transfer from storage to the powder coating application area, reducing manual effort and streamlining the coating process.
2. Organized Workspace: Powder trolleys help maintain an organized workspace by providing a dedicated location for storing and transporting powder, minimizing clutter and improving overall efficiency.
3. Reduced Powder Waste: Powder trolleys help minimize powder waste by keeping the powder contained and preventing spills or leaks.
4. Improved Safety: Powder trolleys contribute to safety by keeping powder dust contained and reducing the risk of electrostatic discharge or other hazards associated with loose powder handling.
5. Enhanced Mobility: Powder trolleys allow for easy movement of powder around the workspace, eliminating the need for manual lifting and carrying of heavy powder containers.

Applications of Powder Trolleys:

Powder trolleys are widely used in various powder coating applications, including:

1. Automotive Industry: Transporting powder for coating car parts, such as bumpers, wheels, frames, and underbody components.
2. Appliance Manufacturing: Moving powder for coating refrigerators, stoves, washing machines, and other appliances.
3. Furniture Production: Transferring powder for coating metal furniture components, such as chairs, tables, shelving units, and decorative elements.

By following these steps and conducting regular maintenance, you can ensure the safe and efficient operation of your powder coating booth, contributing to a productive and safe powder coating process.

Filling the powder trolley

The following section describes how the empty powder trolley is to be filled. The powder trolley can only be filled manually. Before filling the trolley, it may be necessary to carry out a coarse cleaning of the booth. In order to eliminate powder contamination, fresh powder should not be filled directly into the trolley; the following procedure is recommended:

1. Switch on the booth with the button
2. Switch off the electrostatic control units
3. Switch on the sieve with the button
4. Evenly distribute portions of fresh powder directly over the
   sieve. The powder is passed through the sieve and freed
   from any contamination
5. Repeat this procedure until the required amount of powder is
   in the container
6. Check the powder level through the control flap of the
   powder container
   The filling capacity by empty powder trolley is approx. 15 kg plastic
   powder (average value).

Procedure

1. Release the compressed air circuit (input pressure must amount to at least 6 bar)
2. Switch on the booth (switch on the main switch, and press the button), see also chapter “Switching on the booth
3. Adjust the operating parameters on the pneumatics cabinet: Sieve pressure reducing valve (4): approx. 2-3 bar, depending on the powder type Fluidizing pressure reducing valve (3): approx. 0,5-1,5 bar, depending on the powder, the powder should lightly “boil” (check this through the inspection flap of the powder container)
4. Check the fluidization and regulate, if necessary. The adjustment of the required fluidization air pressure depends on the powder type, the air humidity and the ambient temperature. For this reason, only an arbitrary fluidization setting is possible and should be readjusted, according to previous experience for the powder type being used

3. Regular maintenance: Conduct regular inspections and maintenance to maintain the oven’s safety and efficiency.
4. Training and certification: Operators should undergo training and obtain relevant certifications to handle gas-fired equipment safely.

Powder coating of metals is often favored by manufacturers because its finish is tougher than conventional paint. Powder coating is abrasion resistant and will not crack, chip, or peel as conventional paint will. Powder coating is typically done through a two-step process: First, the coating is applied to the part electrostatically with powder coating equipment, and then the newly powdered part is cured in an industrial gas powder coating oven under heat to form a skin.

This process is very efficient since the powder wraps around the back of the part for better coverage and ensures 95% material usage of the powder. The powder coating is a dust-like substance that behaves quasi-fluid. with the help of this material property, the powder coating flows through the hoses and gun of powder coating equipment and reaches the part already ionized with – ion.

This helps the particle hang on the part and stay there till the part is grounded again. The parts that are coated with powder are either manually, or automatically with the help of a conveyor taken into the gas oven, which inside there is a 200 C temperature to melt the powder coating on the parts

Benefits of powder coating and curing in an oven: Heavy-duty construction and quality components Excellent uniformity and heating rates for consistent, high-quality curing results No powder blow-off – reduces rework Uniform heat distribution provides quality cured finishes and optimum cure cycles Quick heat-up rates so you can cure more loads per day Roof-mounted blowers conserve valuable floor space at your facility Fully adjusted and factory tested prior to shipment to reduce installation and start-up times Available with our exclusive energy-efficient oven upgrade

Air Circulation of Gas Powder Coating Oven

Gas-fired heating systems are normally installed in walk-in modular ovens. A high-volume airflow system is employed to provide maximum temperature uniformity. The type of air circulation system used depends on the configuration of the unit. Single module units can only employ a horizontal front-to-back airflow type pattern using centrifugal type blower wheels to generate air circulation. Double module units can employ two different types of air circulation systems, as listed below.

• Horizontal front-to-back pattern using centrifugal type blower wheel.
• •Compound horizontal pattern using propeller-type fans.

The heating and generation of airflow occur in the conditioning plenum, which is normally located on the right side wall of the oven. Blower wheels or fans are driven with extended shafts by motors mounted in the control cabinet.

Heating is achieved by a gas burner that directs a flame down into a vertical perforated flame tube mounted in the manifold next to the conditioning plenum. Thermocouples used for temperature sensing are normally mounted in the workspace on the plenum panel.

Airflow Description

Gas ovens using centrifugal type blower wheels for airflow generation employ a horizontal front-to-back type airflow system. The burner manifold is designed with a vertically mounted flame tube along with perforations on the back side of the manifold. Processed air is drawn into the burner manifold and conditioning plenum, and is heated as it mixes with hot air emitted from the flame tube.

Fresh ambient air is also drawn into the plenum where it mixes with the heated air. Conditioned air is discharged into the workspace through perforations near the front of the plenum housing. The air flows back through the workspace in a horizontal manner to condition the product and then returns to the plenum for reconditioning.

A portion of the processed air is exhausted through a port in the chamber ceiling by the exhaust blower. An air intake port with a manual slide damper is installed in the ceiling of each module to allow fresh ambient air to replenish the exhausted air. Slide dampers are mechanically locked to a predetermined minimum opening.

Heating System of Gas Powder Coating Oven

Important Note: Due to the diverse array of configurations available in a gas heating system, this section will describe basic system requirements, standard equipment used, and fundamental operation.

Application: EMS Powder Coating gas heated ovens are designed to operate with either a natural gas supply or a liquid propane supply according to NFPA 86 (National Fire Protection Association) safety standards. To meet NFPA main gas train requirements, a Closed Position Indicator CPI is used for electrical indication of the safety valve’s closed position. A direct-fired type gas system is used in which the flame is shot through a burner manifold in the conditioning plenum.

Recirculating oven air is heated as it is drawn through the flame. Direct-fired systems are typically greater than 90% efficient. Since products of combustion enter the workspace with this type, it is reserved for those processes that are not emission sensitive. However, many safety precautions are employed with a direct-fired system to compensate for the presence of an open flame. The following sections detail the standard gas heating components used and their operation. The actual components used will vary with your application, so it’s important to check your oven specifications.

Exhaust Blower of the Gas Powder Coating Oven of a Manual Powder Coating Line

An exhaust blower is standard with all direct-fired systems to serve two purposes. Initially, the blower is used along with a purge air timer to purge oven air for a fixed time before the gas burner is fired. When the purge cycle time is complete, the exhaust blower is used to maintain a constant exchange of oven air with fresh ambient air. Ambient air is drawn into the oven through slide dampers mounted atop each module.

A differential pressure switch is used to monitor airflow generation by the exhaust blower, and subsequently for correct operation of the blower motor. These devices use a diaphragm to sense pressure and to mechanically trigger a SPDT Snap Switch when the proper pressure is developed across the blower wheel (or fan). Correct rotation of the motor is necessary for the switch to operate properly. If a loss of pressure / airflow were detected, the switch would open and remove power from the gas burner.

Loss of airflow may result from a motor malfunction, a loose blower wheel (or fan), or constricted air intake or exhaust ports. Blower Spark-Proof Design: The blower housing is designed with a non-sparking type construction. The housing and inlet rings are made of aluminum while the blower wheel is made of stainless steel. Should the blower wheel come off its shaft and strike the blower housing or inlet ring, no sparks can be generated between the two metals.

Gas Burner – Combustion Blower

The three elements necessary for combustion are fuel, oxygen, and ignition. The combustion blower supplies a constant flow of fresh air to the burner. The air is mixed with gas by various methods in order to establish ignition and to sustain complete combustion. The combustion motor starts immediately when the OVEN ON switch is closed. A combustion airflow switch monitors airflow from the combustion blower. This is a differential air pressure type, which will shut down the burner if a loss of airflow is detected.

Gas Burner: A burner is defined as a device used for the introduction of fuel and air into an oven at the required velocities, turbulence, and concentration to maintain ignition and combustion of fuel. A Blast type burner is normally used. This burner delivers a combustible mixture under pressure, normally above 0.3 inch W.C. to the combustion zone. Various flame safety devices are installed within the burner.
