They are designed for clarification (OTR) of suspensions containing few highly refined solid phase and for separation (RTR) of stable emulsions. The centrifuges are made with clarifying or separating bowl.

The centrifuges with clarifying bowl are used for clarification of suspensions containing no more than 1% of highly refined solid phase (oil, albuminous suspension, culture liquid, blood protein).

The centrifuges with separating bowl are used for separation of stable emulsions (separation of water from transformer oil or different greases).

When separating of emulsions the centrifuges operate continuously, when batch separating of suspensions, the centrifuges are required to be stopped periodically for bowl cleaning.
