Changed the outer frame fixing screws of the opening door series.

Utility aluminum doors that meet a wide range of needs.

This is a flush door that meets a wide range of needs, from large doors for the entry and exit of machinery from inspection openings to air-tight doors for super clean rooms that require strict airtight performance for the entry and exit of people and goods. The DR30 is a thin and lightweight aluminum flush door suitable for inspection openings and doors for people, commonly referred to as "man doors," using latch-type locks. The DR34 is a thin and lightweight aluminum flush door that can incorporate electric locks using a dedicated outer frame and is compatible with interlock and access control systems. It has a clean appearance due to its small frame dimensions. There are the "DR30," which uses latch-type locks, and the "DR34," which allows for the incorporation of electric locks using a dedicated outer frame. The DR40 is a versatile aluminum flush door that accommodates a wide range of needs, from various sizes for large doors for the entry and exit of machinery to super clean rooms that require high airtightness for the entry and exit of people. It meets airtight performance grade A-4 even with three-sided frames, as well as four-sided frames.

It is a standard machine hatch.

A detachable machine hatch that allows for an opening size that is difficult to achieve with a door. Since some work is required for detachment, it is a condition that the frequency of opening and closing is low. Additionally, the internal aluminum frame of the TH40 is sturdier and can accommodate larger sizes compared to the TH30. When the height dimension increases, it is recommended to use a plus bar to increase the engagement with the outer frame. ◇TH40◇ The TH40 can accommodate a large size with an effective height dimension of 4500mm. Multiple machine hatches can be removed one by one and then put back in place. The three-sided frame specification is affected by floor irregularities, so it is necessary to ensure a level floor. The four-sided frame specification, which emphasizes airtightness, often has the lower frame getting in the way, so it is common to make the lower frame detachable. Additionally, when the height dimension increases, it is recommended to use a plus bar to increase the engagement with the outer frame. ◇TH30◇ The TH30 accommodates an effective height dimension of up to 3000mm. Its basic functions are the same as those of the TH40. Since some work is required for detachment, it is a condition that the frequency of opening and closing is low.

No unevenness, easy to manage hygiene! Full flat machine hatch.

Flat design machine hatch with minimized protrusions ◇THF40◇ Windows and doors installed on the walls of clean rooms need to eliminate protrusions that could obstruct airflow as much as possible. This is a flat design removable machine hatch that reduces the number of tightening handles and grips for each panel. Additionally, even for tall machine hatches, no ladder or similar equipment is required for installation and removal. ◇THF50◇ Typical removable machine hatches have exposed tightening handles and grips to secure the removable panels. In clean rooms, dust can accumulate on these hardware protrusions, and the protrusions can disrupt airflow within the clean room, potentially affecting product quality. The full flat type removable machine hatch "THF50" features a design that minimizes surface protrusions to the utmost, clearing the highest grade of airtight performance according to JIS, which is grade A-4. It is the ultimate removable machine hatch for clean rooms, ideal for industrial clean rooms (ICR) in semiconductor and precision manufacturing, as well as for bio clean rooms (BCR) that consider GMP and HACCP standards.

Outstanding visibility and stylish! A machine hatch with excellent display effects.

It is ideal when expecting display effects with a detachable machine hatch. Even for the installation of large windows, which can often look awkward with panel types, TK offers a smart see-through type. By assembling transparent resin panels within the frame, a smart see-through type machine hatch is achieved.

Flexible sizes and specifications! A smart-looking framed door.

This is a lightweight frame door that can accommodate from the inspection opening to the large door for the entry and exit of machinery. There are options that can use the Gremon mechanism and electric locks. You can choose between two types: one with a middle rail that separates the upper and lower panels, and one without a middle rail. This lightweight frame door is suitable for inspection openings and doors for human entry and exit, commonly referred to as "man doors." There are two models available: "DK30," which uses a latch-type lock, and "DK34," which allows for the integration of an electric lock using a dedicated resin cassette and a dedicated outer frame. You can choose between the type with a middle rail that separates the upper and lower panels and the type without a middle rail. The DK40 is an aluminum frame door specifically designed for large doors for the entry and exit of machinery. By increasing the vertical frame size, it enables the installation of the Gremon mechanism and electric locks, achieving a larger frame door. It can also be used when you want to secure a large window in a large door.

In public works, not only construction quality but also safety measures, environmental considerations, and unique site-specific innovations are important. One proposal that is easy to suggest is the civil engineering CLT "Hyper CLT Mats" utilizing wood. These can be used for temporary roads, access routes, worker pathways, and material yards, improving the site environment from a different perspective than steel plates. It is also characterized by the ease of explaining the purpose of implementation to clients, such as measures against summer heat reflection, noise reduction, CO2 fixation, and consideration for the landscape. Furthermore, being a **NETIS registered technology "TH-250021-A"** by the Ministry of Land, Infrastructure, Transport and Tourism is a significant point when proposing in public works. It can be considered as one of the new technology applications and creative innovations. Clearly communicating "why this material is used" is also important when making proposals to government offices. The Hyper CLT Mats, which combine wood, NETIS, and civil engineering, are expanding their use in public works as a new civil engineering material that balances practicality and environmental consideration.

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding methods for repairs often change the base material around the crack due to heat, leading to residual stress and deformation, which constantly carries the risk of "crack recurrence" and "secondary damage." Hinode Waterworks Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for the repair of metal cracks without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material at all. Repairs can be made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. For more details, please contact us or download the catalog.
