Chairman's Vision

In 1996, the chairman of the board set up a company in Wufeng, Taichung, and established the research and development, manufacturing and production of induction faucets. Implement true 100% MIT.
Although OEM was the main market in the initial stage. But at that time, it had already built a reputation in the industry for high quality and high durability.
The DOL brand initially aimed at medical care, hospitals and clinics, hoping to enter the medical market and protect medical personnel from exposure to infection.
During SARS in 2002, we entered surgical washrooms, nursing stations, and emergency centers in various hospitals. The first line of defense has been set up for medical personnel across Taiwan.
Since then we have established a firm foothold in the healthcare setting and have slowly expanded outward.
In 2019, COVID-19 Taiwan has done the best demonstration, and we also hope that DOL can further protect the land of Taiwan.
So starting in 2021, we will mass-produce high-power-saving IC boards and sensors.
Let the life of the battery increase from 2-3 years in the general industry to 6-8 years.
DOL's brand has also been elevated to a position second to none in the industry.
