Air Conditioning Systems Work

We provide air conditioning systems for industrial use and air conditioning equipment, water supply and drainage and sanitation equipment for a variety of facilities including offices, medical and welfare facilities, etc.

Industrial Process Air Conditioning Installation

We propose, design and construct the optimal environment for production facilities, factories, data centers, research facilities, etc., controlling temperature, humidity, air flow and air filtration.We also provide energy-saving equipment to meet customer needs.

General Air Conditioning and Sanitary Equipment Installation

We design and install in a variety of facilities including office buildings, schools, hospitals, hotels, etc., the air conditioning and water supply and drainage / sanitation equipment such as sprinkler systems that are essential for people to be comfortable.


Energy Saving and CO2-Reducing Solutions

We conduct operational status hearings, on-site surveys, and analysis of actual performance data, and make proposals for optimal energy-saving and CO2 reduction according to requirements such as budgets and reduction targets. From general air conditioning to industrial process air conditioning, we deliver safety and reliability to our customers.
