Company information
Since its founding in 1945, our company has continued to provide refrigeration and freezing equipment, which is our core technology, to the industrial sector. In response to the advancement of medical technology, we developed blood storage devices, and since 1997, we have been manufacturing explosion-proof refrigerators and freezers that meet safety standards as part of our commitment to labor safety and health measures. The past twenty years for our company have been a history of trial and error, honing and integrating two technologies: refrigeration and freezing technology and explosion-proof safety technology. Currently, we have a wide range of products, including certified items for medical and industrial safety applications, but the development of these products is the result of diligent efforts to faithfully improve them in line with on-site needs. Our manufacturing of temperature control equipment that adds safety to the industrial and medical sectors has been recognized, earning us the Osaka Prefecture Excellent Manufacturing Company Award in 2010 and being selected as one of the "100 Energetic Manufacturing Companies in KANSAI" by the Kinki Bureau of Economy, Trade and Industry in 2011. We are committed to continuing to support the domestic and international industrial and medical sectors with our temperature control technology and fulfilling our social responsibilities.
