[Must See] Awarded the Excellent Award at the 31st Small and Medium Enterprises Excellent New Technology and New Product Awards! Introducing an explosion-proof testing device with abundant new features such as automatic control and automatic gas treatment!
The explosion-proof testing device "H1E-1510-H(n)" for aircraft equipment is designed to conduct explosion-proof tests required during the development phase of aircraft equipment, in accordance with applicable standards. The explosion-proof test is performed to demonstrate that the equipment in question does not ignite surrounding explosive gases due to operation or overheating. This device has been developed, manufactured, and inspected under the supervision of a quality inspector (DER) appointed by the FAA (Federal Aviation Administration) and meets U.S. standards as a Japanese manufacturer. Therefore, it can be used not only for updating aging equipment but also for the introduction of new testing facilities. 【Features】 ■ Explosion-proof testing device that meets U.S. standards for civil aircraft equipment ■ Equipped with automatic control functions to perform the entire explosion-proof testing process automatically ■ Features a large silencer, allowing for indoor installation ■ Equipped with an automatic gas treatment device to handle unburned explosive gases ■ Includes a high-speed camera capable of image analysis of testing conditions ■ Safety tests have been conducted (details in the video below) ■ Received the Excellence Award at the 31st Small and Medium Enterprises Excellent New Technology and New Product Award (announced on April 9, 2019) *Please feel free to contact us for more details.

Detailed information
-
By installing a large silencer, the impact from detonation during an explosion that may occur if the test specimen is defective is mitigated, allowing for quiet operation even in the event of a test failure. Additionally, without a silencer, installation would be limited to outdoor settings due to the impact, but this device enables indoor installation by incorporating a silencer.
-
The test specimen is set up in the main chamber, and explosive gas is introduced under the required conditions (temperature, altitude, etc.). The specimen is operated in an environment with explosive gas, and it is confirmed that there is no detonation. After that, explosive gas from the main chamber is introduced into the sub-chamber, ignited, and it is confirmed that it was indeed explosive gas. After the process is completed, all gases are automatically processed and released into the atmosphere. The equipment necessary for these operations is realized as a single unit and is programmed for automatic operation.

The main chamber and sub-chamber are composed of round clutch door-type pressure vessels that our company has been handling since 1955 and continues to sell nationwide as core technology. Utilizing the control technology developed through the manufacturing of mushroom high-pressure sterilizers and autoclaves, we provide an automatic control function that conducts the entire process of explosion-proof testing in automatic operation.

Company information
We have leveraged the technology we have cultivated through boiler manufacturing to aim to become Japan's leading "clutch door" manufacturer, focusing on the production and sales of round and square clutch door-type pressure vessels. As pressure vessels for production equipment, their applications have diversified alongside the development of various industries and advancements in production technology. We consistently manufacture everything from various steel plates to industrial machinery at our factory, and we also handle OEM for various processing equipment, including our own brand of mushroom culture sterilization devices and autoclaves. By newly establishing a research and development department, we aim to enhance our technological capabilities to respond to the high added value of production equipment, while further refining our "blacksmithing skills" to continue creating valuable products in the future.
