Unique, Best-Selling Products and Services

■  “OMX” hot water, air conditioning, and ventilation system using solar power and exhaust heat.

With the technology and know-how we have accumulated over many years, we developed the world’s first household system for both hot water and air conditioning (cooling, heating) in a single unit, instead of separate heating and cooling units. Heat from the sun and in the atmosphere, which differs in summer and winter, is efficiently controlled and used for indoor heating and water heating. In addition, the heat that is generated through ventilation is used, as needed, to reduce the necessity of energy for heating and cooling. This is a highly efficient and next-generation energy-saving system for households.

Appeal to New Graduates/Mid-Career Recruits

We provide a full range of services from product development to manufacturing and sales. Our corporate culture encourages young people to take an active lead and attempt new challenges in order to grow, in a variety of fields regardless of educational background.
