NW-650 DEF Solution Production Equipment

Technological Craft of DEF Solution Production Equipment

1 Preface of DEF Solution Production Equipment

Shandong Newblue provides one set Adblue production system.

1.1 Raw water quality: use tap water supplied by customers.

1.2 Output quality：meet customer's requirement, 2 stage RO conductivity less than 10µs/cm, EDI conductivity＜1µs/cm.

1.3Users need to provide raw water, electricity, etc.for the system.
