Alfa Laval decanter centrifuge rebuild service

Decanter centrifuge rebuilds and upgrades

Restore and improve decanter centrifuge performance for sludge dewatering and thickening

If your decanter centrifuge is showing signs of reduced performance due to wear and tear or changing process conditions, it may be time to consider a rebuild. Refurbishing or upgrading your decanter centrifuge can restore, or even improve, sludge thickening and dewatering performance. With decades of expertise in the industry, Alfa Laval can restore equipment to factory OEM specifications, with factory certified welders and mechanics.

A rebuild can be significantly less expensive than a new machine or full rotating assembly. By avoiding expensive engineering or structural expenditures associated with new equipment, you can significantly save time and money while ensuring that you continue to get the process results you need.
