ALDEC G3

ALDEC-G3_decanter_front_640x360.png

The Alfa Laval ALDEC G3 features the same technology as ALDEC G3 VecFlow™, except for the feed zone. ALDEC G3 has a standard feed zone, giving it somewhat lower performance and higher power consumption. It is a good fit for a wide range of applications where high separation performance and low power consumption are required, but where the extra benefits offered by VecFlow™ are not necessary. An Alfa Laval ALDEC G3 can be upgraded to the VecFlow™ design.

ALDEC G3 is available with capacities from 23 to 225 m3/h.
