An energy-saving system that has achieved a 98.3% reduction in monthly power consumption! It enables CO2 reduction and lower electricity costs without changing the way air conditioning equipment is used!

The running costs of air conditioning equipment are a significant burden for management. The largest loss comes from the power consumption of pumps. We aim to reduce the power consumption of these pumps and achieve energy savings. The reduction effect has been proven to be between 50% and 90%. This meets two needs: reducing CO2 emissions and lowering electricity costs, without changing the way air conditioning equipment is used. [Features] ■ Unprecedented high reduction rate By controlling the flow rate of chilled water pumps and cooling water pumps with inverters, we can significantly reduce the power that was previously wasted. We can achieve a reduction of approximately 50% to 90% in power consumption. ■ Clear implementation effects We continuously monitor the operating conditions of the equipment and the electricity usage, accumulating data that allows us to compile cost reduction results for one day, one month, and one year. ■ Remote monitoring and maintenance In the event of a system failure, an emergency email will be sent to our support center and maintenance personnel's mobile phones. System operation control can be performed anytime via the internet. *For more details, please request materials or view the PDF data available for download.

This includes areas referred to as communications or IT, as well as the installation of machinery in plants and civil engineering.
