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

Utility aluminum doors that cater to 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 slim 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 slim and lightweight aluminum flush door that allows for the integration of electric locks using a dedicated outer frame, and it can also accommodate interlock and access control systems. Its frame has a small profile and dimensions, giving it a neat appearance. There are the "DR30," which uses latch-type locks, and the "DR34," which enables the integration of electric locks with a dedicated outer frame. The DR40 is a versatile aluminum flush door that accommodates a wide range of sizes, from large doors for the entry and exit of machinery from inspection openings to those requiring high airtightness for super clean rooms.

It is a standard machine hatch.

A detachable machine hatch that allows for an opening size that is difficult to achieve with a door. Some work is required for detachment, so infrequent opening and closing is a condition. 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 unevenness in the floor, so it is necessary to ensure a level floor. The four-sided frame specification, which emphasizes airtightness, tends to have the lower frame obstructing, 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 can accommodate an effective height dimension of up to 3000mm. The basic functions are the same as the TH40. Some work is required for detachment, so infrequent opening and closing is a condition.

No unevenness, easy to manage hygiene! Detachable panel flat type.

Flat-type removable 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-type 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 the removal and installation process. ◇THF50◇ Typical removable machine hatches have exposed tightening handles and grips to secure the removable panels. In clean rooms, dust and debris 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, meeting the highest JIS airtightness performance 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.

The size and specifications are completely customizable! A stylish 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 middle rail version that separates the upper and lower panels and the version 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 allows for 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.

We will be exhibiting at the only comprehensive and cross-sectional international convention in the marine field in Japan, "Techno-Ocean 2025." In this exhibition, we will introduce a wide range of specialized survey services related to offshore wind power generation projects, including wind and sea condition surveys, O&M, sediment surveys, and fishing ground environmental monitoring. We will also showcase marine surveys and seagrass bed investigations using marine robots such as autonomous surface vehicles (ASVs) and underwater drones, as well as the collection of dead fish in aquaculture operations.

The energy policy promoted by the government has finally made a significant shift from "quantity to quality." The previous large-scale introduction of renewable energy policies relied on inexpensive foreign-made panels, leading to the chaotic installation of mega-solar farms across Japan's land, which created environmental, landscape, and waste issues. As a result, Japan's energy self-sufficiency rate remains at a mere 13%, and even with the advancement of renewable energy, "import dependence" has not been resolved. In light of this reflection, the focus moving forward will be on "developing domestic energy technologies" and promoting "self-consumption type renewable energy." Among these, perovskite solar cells are lightweight, highly efficient, and offer great flexibility in installation, making them a trump card for "decentralized renewable energy" that can be easily retrofitted onto building walls and roofs. Kenneth Energy Development Co., Ltd. is developing a "selective self-consumption solar power generation system" that utilizes domestic panels and perovskite technology. Based on a track record of 83 projects nationwide and a total construction cost of 908.4 billion yen, it supports the industry's "energy independence." Now, renewable energy is entering an era of "security infrastructure."

"Perovskite solar cells" are once again emerging at the center of Japan's renewable energy policy. Mr. Takai has proposed "nurturing domestic technology for renewable energy" as part of energy and industrial policy, causing related stocks to attract attention in the market as the "Takai trade." The background to this is Japan's long-standing dependence on foreign-made panels in its renewable energy structure. While inexpensive imports have supported proliferation, they have also left a "negative legacy" of forest development, disposal risks, and price fluctuations. If this continues, both the land and energy supply will be controlled by foreign entities—this sense of crisis is the trigger for policy change. Perovskite solar cells possess the trifecta of being lightweight, highly efficient, and low-cost, making installation in existing buildings easy. Development is progressing as a domestic technology, and it is expected to become a mainstay for self-consumption power generation in the future. Kenneth Energy Development Co., Ltd. is developing a "next-generation self-consumption solar power system" with an eye on these perovskite cells. With over 8,000 installations nationwide and expertise in subsidy support, they are turning companies' "energy independence" into reality.
