This unit has recently been totally reconditioned by SPOMASZ-Wronki decanter factory work shop in 2020. The unit is now in our stock and ready to be put back in operation.

The tricanter unit will be delivered without electrical panel and without lifting tools.

We have in stock an original Alfa Laval control- and steering panels for automatic operation of a NX 438 decanter unit designed for a 55 kW main motor and for a 11 kW back drive motor. The main motor and the back drive motor, are connected via frequency converters to the Alfa Laval Differential Speed Control (DSC) system. We can optionally offer the tricanter unit with this electric panel and a 55 kW main motor.

Also, optionally, we can offer this tricanter unit with lifting tools and other special tools.

Dimensions and weight for the tricanter unit as to the pictures: L 4,8m x W: 1,2m x H: 2,2m - estimated weight: 5 tons.
