The "Frame Arrester" is a device that prevents the spread of fire and explosion in the event of a flame occurring on the outlet side when installed on pipes or tanks. The extinguishing element adopts a clean ribbon-type element. By efficiently absorbing and dissipating heat, it suppresses the propagation of flames. We offer a lineup of products optimized for the balance between extinguishing performance and pressure loss, ranging from general use to high-risk gas groups. Custom solutions are available to meet specific needs. 【Features】 ■ Obtained EC Directive 94/9/EC (ATEX 95/CE marking) ■ Also obtained EN ISO16852:2010 ■ Fine mesh spacing in the extinguishing element ■ Protection against deflagration, detonation, and stable combustion *In addition to the product catalog, explanatory materials are available. Please view them via "PDF Download."

The "Rupture Disk" is a non-mechanical pressure safety device that operates reliably at a predetermined set pressure. It instantaneously releases excess pressure within a container at a preset pressure and temperature, protecting the system and equipment from excessive pressure caused by runaway reactions, human errors, and other factors involving powders, liquids, and gases. 【Features】 ■ Non-mechanical ■ Instantaneously releases excess pressure within a container at a predetermined pressure and temperature ■ Releases excess pressure from powders, liquids, and gases, protecting the system and equipment ■ Standardized as a JIS B8226 rupture disk safety device *For more details, please refer to the PDF document or feel free to contact us.

<Overview> A rupture disk is a non-mechanical pressure safety device that reliably operates at a predetermined set pressure. It instantaneously relieves excessive pressure within a container at a preset pressure and temperature, protecting the system and equipment from excessive pressure caused by runaway reactions, human errors, and other factors, by releasing powders, liquids, or gases. <Features> Rupture disks are standardized as rupture disk safety devices under JIS B8226. JIS B8226 specifies that "this standard pertains to safety devices composed of rupture disks, holders, vacuum supports, etc., established to prevent damage to sealed devices such as pressure vessels, piping systems, and ducts due to excessive pressure or vacuum." By installing a weaker section (weak spot) in part of a pressure vessel or piping that is weaker than the strength of the pressure vessel or piping, when internal pressure rises abnormally, only this weak section will rupture, releasing the internal pressure and protecting the vessel or piping. A rupture disk is defined as this weak section, given specific conditions such as shape, dimensions, pressure, and temperature.

• Piping Materials

The explosion vent is a panel-type explosion protection device that protects equipment from destruction caused by an explosion when an explosion occurs inside the device or container. When an explosion occurs, the explosion vent opens fully at a pre-set pressure, releasing the explosive material and lowering the pressure inside the container to a safe level, thus preventing damage to the equipment. <Features> - Panel material is stainless steel - Insulation material can be attached (optional) - Burst testing conducted with certification provided - Available in square and round shapes, accommodating various vent areas - Sanitary compliant (optional) ◎ We are distributing explanatory materials that introduce this system and trends in dust explosion countermeasures!

◆Overview Installed on the connecting piping as an inflatable barrier, it prevents the propagation of explosions. This is a pneumatically operated inflatable pinch valve that is activated by external signals from explosion venting outlets or explosion suppression systems, or by dedicated pressure and optical sensors. It has the following fail-safe features. ◆Features - System anomaly alarm (power voltage drop, pneumatic pressure drop, wear of the inflatable rubber) - The valve automatically closes in case of abnormal tank air pressure. - In the event of a power outage, the valve automatically closes. ★ For more details, please request the documentation ★

• valve

<Overview> This is a knife gate type high-speed shut-off valve that is installed on connecting piping to prevent the propagation of explosions. It is activated by external signals from explosion venting outlets or explosion suppression systems, or by dedicated pressure sensors. It operates at high speed within 20ms to 50ms. <Specifications> Size: 200mm - 500mm Material: SUS Flange: ANSI 150, DN PN10/16 Maximum Pressure: 1.6MPa(G)

The "Explosion Suppression System" detects the "pressure wave" at the moment a dust explosion occurs inside equipment such as dust collectors, dryers, and powder handling systems, and suppresses the explosion by spraying extinguishing agents. It prevents damage to equipment and containers with the "suppression cannon" and stops the propagation of explosions with the "shear cannon," thereby preventing the expansion of damage. 【Features】 ■ Can be installed on existing equipment and containers ■ The status of the system and the content of alarms can be checked on a touch panel monitor ■ Uses baking soda (sodium bicarbonate) as the extinguishing agent, making it safe for food plants ◎ We are distributing "explanatory materials" that introduce this system and trends in dust explosion countermeasures!

<Overview> Factory fires are determined by initial firefighting efforts. In the handling of powders in wood processing, synthetic resin processing, metal processing, agricultural material processing, chemical industry, food processing, textile industry, power generation, etc., there is a risk of dust fires and dust explosions, which often lead to major accidents. The spark extinguishing system detects heat or near-infrared light through sensors and sprays water from extinguishing nozzles for initial firefighting. <Features> ● Spark detection in non-light zones ● Spark detection under daylight ● High temperature detection ● Frost prevention function ● Pressure booster adopted (for water pressure boosting) ● Automatic self-diagnosis function ● Fire extinguishing time data ● Alarm limit setting for spark intensity ● Alarm limit setting for continuous extinguishing ● Centralized management possible via data bus ● Easy post-processing as no extinguishing agent is used ● Compliant with ATEX Zone 21, certified under ATEX Directive 94/9/EC
