A manufacturer of heat exchangers, desiccant dehumidifiers, and VOC concentrators, and experts in dry & clean room design.

We have been operating our business in Japan for over 60 years as a manufacturer of industrial specialized air conditioning equipment, such as total heat exchangers and desiccant dehumidifiers.

Our greatest strength lies in the fact that we develop the rotor — the heart of the machine — in-house, and carry out all aspects of product design and manufacturing within our own company.

We also have extensive experience in dealing with overseas companies and have conducted business with countries and regions across more than several dozen nations.

Recently, to strengthen our relationships with customers in the Southeast Asia region and India, we have established a local subsidiary in Thailand.

With our experience and expertise, we hope to be of service to a wide range of customers.
