ZJ-BAS Digital Bar Ionizer

Advanced Features in 3 Aspects

Wide Area

Ionizes areas wider than the Ionizer itself.

Short Distance

Achieves the highest level of short-distance ionization in its class.

Long Distance

Steady ionizing performance, even over long distances.

Three Technologies Supporting Effective and Efficient Ionization

Technology 1: Ion Sensing and Variable-AC System (Industry First!)

An ion sensor installed on the bottom of the Ionizer detects the charge and ion balance. The applied voltage is flexibly controlled according to the ion
balance conditions to raise ionization efficiency.

Technology 2: Micro Power Spraying (MPS) Structure

High-speed airflow is achieved by minimizing the air nozzle diameter. An optimal cone shape is also employed for the inside of the nozzle to further improve ion dispersion. By using a special ring guard shape to pull passive (external) air into the active air stream, the total airflow is dramatically increased.

Technology 3: Optimized Discharge Electrode Pitch Optimized Discharge Electrode Pitch

Setting the discharge electrodes at a pitch that is 80 mm longer than in our previous models achieves an optimal layout that unifies ionizing performance and reduces ion recombination. This model ionizes over long distances with or without the use of an Air Purge Ionizer.

Uniform Ionization

Linked Ionizers cover a wide area without causing uneven ionization.

Linking up to 7 Units *

Long Ionizers are required to meet the needs of increasingly large liquid crystal glass panels. Ionizers as long as two meters are not only difficult to transport and install, but also pose difficulties in achieving uniform ionization. The highly thorough ZJ-BAS Ionizer solves this problem by connecting Ionizers together.

Two Forms of Uniform Ionization Achieved by Linking Function

Uniform Airflow

The air supply ports on previous models were only on both ends, so the airflow was weak in the center of long Ionizers. By connecting ZJ-BAS Ionizers together, air is supplied from the center part as well, thus achieving a uniform airflow and eliminating uneven ion discharge at medium and long distances.

Uniform Ion Balance

For example, when both sides of a workpiece are charged, a long Ionizer will adjust the amount of ions according to the entire Ionizer length, so an area that is not charged may take on a reverse charge. By using linked ZJ-BAS Ionizers, each Ionizer senses the charge condition. Because only the Ionizers on both ends then control their ion amounts in response to the charges, reverse charging does not occur.

Technologies that Support Uniform Ionization

Technology 1: Supplying air with no pressure loss

By arranging discharge electrodes on both ends, the Ionizer can handle an area wider than the length of the Ionizer itself. This eliminates dead zones even when linking Ionizers, and achieves uniform ionization.

Technology 2: Ion Sensing and variable-AC system prevents ion recombination

Because the ZJ-BAS Ionizer uses a method in which the linked Ionizers operate using the same power supply, the positive and negative ion generation timing between the Ionizers is synchronized. Also, the sensing and variable-AC system control the amount of ions while synchronizing the Ionizers. This reduces ion recombination between the linked Ionizers, and achieves uniform ionization.

Ion Sensing and Variable-AC System (refer to left graph below)

The amount of ions is adjusted even when a charge is detected, so synchronization with matching polarity is maintained.
 

AC System (Refer to right graph below)

If the synchronization of the timing is lost, the polarity is reversed.

Improving Ease of Use

The Digital Ion Display Supports Safe, Reliable settings (Industry First)

From either the Remote Control or the Ionizer...

The Digital Ion Display guides you when making settings. Settings that are important for ionization performance, such as the frequency and ion balance, can be made and displayed safely and reliably from the ionizer itself, or by using the Remote Control.

A Variety of Displays

Ion Balance Display

The charged state is displayed using colors.

Set Value Display

The current set value is shown on the right side of the display. The set value can be numerically confirmed, so the setting can be quantified. This allows identical settings to be made reliably and in a short time even across multiple Ionizers.

Operation Stop Mode Makes Maintenance Easy

The Operation Stop Mode allows for safe cleaning and replacement work. The digital display and LED lamps tell you that the Ionizer is in Operation Stop Mode so you will not forget to return to Operation Mode when you are finished doing maintenance. Both regular operations and maintenance can be done safely and reliably.

Operations from external equipment, such as stopping ionization and performing status management, can be done easily by connecting the Ionizer to a PLC using an I/O cable.

Low Running Cost

M.P.S. Construction Prolongs the Required Maintenance Period by 5 Times Compared to Our Previous Model. Greatly Reduce Maintenance Requirements.

The M.P.S. nozzle emits clean air from around the discharge electrode, thus decreasing the amount of foreign matter adhesion, and dramatically extending the time before cleaning is required.

Energy-saving is a Basic Concept for OMRON Ionizers

Generally, bar-type Ionizers use compressed air. Therefore, a large amount of compressed air is needed, especially for long-distance or high-speed ionization. This increases the load rate of the compressor, and consumes large amounts of electricity. The ZJ-BAS uses an optimized discharge electrode pitch and M.P.S. nozzle to improve ionization performance while using an energy-saving structure (low-current consumption) that is environmentally friendly.

The M.P.S. nozzle allows for efficient airflow while reducing current consumption.

80-mm Discharge Electrode Pitch Dramatically Reduces Replacement Cost

The 80-mm discharge electrode pitch and variable-AC system reduce the number of discharge electrodes required by 60%. In addition to reducing the cleaning time, the periodic replacement of the electrodes has also been reduced, thereby dramatically reducing the running cost of the Ionizer.
