Since the company's establishment in in 1923, our business objective has been heating-related work, starting with "Entertainment Hall Audience Seating Cooling (Mitsukoshi)" and "Whole Building Heat Pump Air-Conditioning (Kyoto Dento)," and up to now we have built numerous air conditioning equipment for renowned buildings.

Since 1960, when air conditioning became commonplace, we have achieved the No. 1 position in the construction industry, providing comfortable air conditioning systems to buildings such as the World Trade Center and other skyscrapers and department stores, high-quality air conditioning systems to buildings such as the New National Theatre, Tokyo and the National Art Center, Tokyo, and large volume air conditioning systems to buildings such as Tokyo Dome and Kyoto Station. In addition, we also worked on the Osaka World Exposition venue and Shinjuku subcenter, the world's largest district heating and cooling systems.

Meanwhile, we have a strong track record in providing air conditioning for a wide variety of industrial processes, starting from temperature and humidity adjustment in a pre-war rayon factory (Teijin Iwakuni), working on large-scale clean rooms for manufacturing electronic parts such as LSIs and LCDs and pharmaceuticals since 1970, and recently, working on dry rooms that are indispensable for the battery manufacturing process.

We will continue to work as a reliable professional for new construction or refurbishment, responding to customer's needs in every era.

TopicJapan's first heat pump heating facility

Mr. Yanagimachi, our first president, went on a business trip to the US in 1929 and met with Prof. W.H. Carrier. They discussed the possibility of a heat pump based on a turbo chiller and Yanagimachi strengthened his intention after the very promising answer from Prof. Carrier. After returning home, Yanagimachi advanced the practical research, and in 1932, he installed a system in the Murayama residence, a 230 m² two-story wooden house in Mikage Town, Hyogo Prefecture. This was the first heat pump-based heating system to be built in Japan. The refrigerator capacity was a 2RT ammonia refrigerator. In the nighttime, the bedrooms on the second floor (about 60 m² in 3 rooms) was heated or cooled, and in the daytime, the duct was switched and the living room on the first floor (about 100 m²) was heated or cooled.

When the company was first established, it had no choice but to import air conditioning equipment, and Article 3 of our Articles of Incorporation listed "Import and sales of heating equipment and other foreign products." However, in order to build equipment that truly satisfied its customers, the company had no choice but to build its own machinery and tools.

The company developed numerous products including the Takasago Ebara Turbo refrigerator - the first domestically-produced product built in 1930 - air washers, Sirocco blowers, and cooling towers.

Takasago developed a number of systems and items of equipment in response to the demand for individual control of air conditioning. These include the water heat source HP (heat pump) system PMAC® developed in 1971, the ice thermal storage system SIS^® (super ice system) for electrical power leveling, the clean room system TCR-MP^® that responded to the needs of the industry, and the energy saving type dehumidifier WINDS^® for dry rooms.

The spirit of the founder of "If we cannot find a good product we will make it ourselves" has been handed down to the present day.

Takasago EBARA Turbo Refrigerator

　We worked with Ebara Corporation to develop this refrigerator, and successfully achieved the first domestically-produced unit in 1930. The first unit was installed in Osaka Asahi Building in 1931, and was subsequently followed by many units installed at department stores, theaters, factories and other facilities. It was certified as The Japan Society of Mechanical Engineers' "Machinery Heritage" in 2010, and as the Japanese Association of Building Mechanical and Electrical Engineers' "Building Equipment Technology Heritage" in 2014. The turbo refrigerator in the photograph was delivered to the Konishi Roku Roku Sakurasya Hino Factory (currently Konica Minolta) in 1937 and was used until 1974 when equipment was replaced. Today, the Takasago EBARA Turbo Refrigerator is located at our Innovation Center where it is exhibited.

We have always led the industry in providing equipment for creating comfortable spaces that customers require along with changes in society, such as air conditioning equipment for comfortable office environments, industrial air conditioning equipment that makes full use of advanced technology which is indispensable for the manufacturing industry, energy conservation and CO₂ reduction technology for the preservation of the global environment, and as a service provider.

Within this, in 2012, our datacenter energy-saving air conditioning system "IDC-SFLOW^®" won the "Green IT Award" Special Award and "SWIT^®" received the Agency of Natural Resources and Energy Director-General Award at the "Energy Conservation Grand Prize." In this way, our technology goes beyond the normal confines of the industry and has been highly appreciated from the perspectives of environment creation to operation.

Through further development of the technologies we have accumulated, we aim to become an "Environmental Creator" by bringing together the strengths of the Takasago Thermal Engineering Group as a whole, operating as a global company, and providing solutions and consulting from the customer's point of view.
