About us

Message from President and CEO

Our corporate philosophy is to continuously contribute to society.
We have been holding up this ideal since we were established in 1982. To realize this ideal we have been trying to improve our skills and knowledge to better meet our customers’ needs.

Our company is an all-around manufacturer. Special environmental control technologies such as vacuum, pressurization, steaming and heating are applied to all our products. We handle the manufacture of our products from the earliest stage to the last, from creation to designing and production. In this way, we can ensure that our original machines satisfy our customers’ needs.

We will continue our firm determination to improve ourselves with pride and enthusiasm. In addition, we are confident that innovations in high technologies will provide boundless possibilities for us to create new original products to meet our customers’ diverse needs.

About us

We are an engineering company that develops, designs, manufactures, and sells equipment that is useful to society through comprehensive control of pressure, temperature, humidity, etc. We are unique in the development, design, and manufacture of high-pressure equipment, which is subject to particularly high pressure and requires strict manufacturing approvals. We also hold a number of practical patents related to it. Devices that control pressure, temperature, and humidity always require a container as a space for physical control. This vessel has a wide range of hazards, especially where "pressure" control is required, and is subject to legislation in many countries. Therefore, specialized techniques and skills are required. This is where our experience comes in. We have obtained CE marking certification for our equipment.
