The TEC-1865HD-FVS centrifuge is a Full Variable Speed model, which provides operators with the ability to adjust operating parameters including the differential speed, bowl speed, and feed rates while the centrifuge is in operation.

Our 1865 Full Variable Speed centrifuge has the added benefit of a “direct drive” Conveyor drive assembly.  With this new conveyor drive design, we have increased the efficiency of the conveyor drive motor significantly as well as eliminated any maintenance issues associated with utilizing belts and sheaves.

Flexibility, reliability and performance are attributes that all of our centrifuges come with.  Tecumseh, we truly are the experts!
