The SPI series of Centrifugal Extractors from DEPRAG employs an unconventional technology that produces high potential and high-grade output. They speak of the holistic system efficiency used in the olive oil extraction industry. They utilize a full stainless steel system, where all wear parts are coated with wear proof materials. The hydraulic coupling offers soft starting, and the electronic revolution center is responsible for the bowl and the differential scroll speed. Moreover, the ground is insulated due to anti vibration supports.
