Association of 3 Co., Ltd.

Association of Three Co.,Ltd. is a manufacturer of equipment for the “environmental industries” (the Three in the company name are earth, air and water, not people!). Thepthai Udomchanya started this company in 1993 and has built it into a very successful organisation supplying equipment for water and wastewater treatment throughout Asia and beyond. We have an excellent staff and workforce, many of whom have been with the company almost 20 years, and we make equipment which is technically superior, developed by the expert knowledge of our staff. We have a flexible and very capable manufacturing team, so we can make each unit as you need it, to match your exact requirements. From 2004 we have expanded our field of activity into the “earth” part of Association – Solid Waste. This will also benefit our third environmental discipline, “air”.
