Geothermal Facility Case Study: Toa Automobile Manufacturing Co., Ltd. (Yamaguchi City, Yamaguchi Prefecture)

When employees arrive at work, it is quite cool! It shortens the hot hours.

At the factory of Toa Automobile Industry Co., Ltd., in the welding department, which is the main operation, the temperature in the workplace can reach nearly 40°C in the summer, raising concerns about the health risks to employees. [Challenges] - In the welding department, the temperature in the workplace can reach nearly 40°C in the summer, raising concerns about health risks to employees. - Air conditioning is unrealistic considering the installation and running costs. - Although a large water-cooled blower with low costs was considered, it could not be implemented due to concerns about welding flames and rust on iron products caused by humidity. Therefore, it was decided to introduce "Geo Power" with the expectation that a temperature drop of 2-3°C in the welding department would significantly reduce health risks. Due to its low running costs, keeping it on 24 hours a day ensures that when employees arrive, the environment is considerably cooler, thus shortening the duration of high temperatures. *For more details, please refer to the related links or feel free to contact us.
