SAF type

Due to law registration of Dioxin treatment in 1999, many incinerators that didn't meet the requirement of new law were left unused, wainting for demolition works. Those demolition works require cleaning process of chimney or furnace, producing highly-conrtaminated water with dioxin, and cost a lot.

Concentration device for Dioxin-contaminated water

Designed for civil works in urban area, this machine can retrieve sand from mud water effectively.

Sand Master

Chemical tank

Data can be sent to computer directly resulting in paperless procedures. Accumulated flow volume can be shown in calculation fomula with analog values. Or pulse input device is applied since pulse signal from flowmeter is normally used. With the device, contact input becomes feasible, alarm can be recorded. This special display allows you to put comments on screen by touch-pen.
