The BTUX 305 pilot separator is suitable for feed rates up to 2000 l/h, is available in a variety of configurations and therefore can be adapted for virtually any application.
Suitable for hazardous materials, as it meets ATEX requirements for zones 1 or 2. It can be supplied with an inert gas purge system, thus ensuring a high level of safety.
When operating with biologically hazardous material, the system can be supplied in a hermetic version for steam sterilization, which meets NIH requirements for BLS2.
Applications
The machine is designed for clarification duty, separating particles from one liquid, especially shear sensitive particles. The sterilizability makes the machine suitable for most biotechnological separation duties. The solids content in the feed is normally in the range of 1–20% by volume, but can vary between different duties.

Standard design
The machine consists of a frame that has a horizontal drive shaft, worm gear, lubricating oil bath and a vertical bowl spindle in the lower part. The bowl is mounted on top of the spindle, inside the space (bowl casing) formed by the upper part of the frame, the solids collecting cover and the frame hood.
The bowl casing is double-walled for cooling and noise reduction. There is a mechanical seal at the top of the spindle to make sterilization with steam possible.
For continuous pressurized discharge of separated solids the machine is fitted with a non-rotating device, a paring tube, positioned inside a central chamber, to which the separated solids flows through vortex nozzles.
All metal parts in contact with the process liquid are made of stainless steel. For CIP, the bowl contains an automated hydraulic operating system or discharging. It is a system, in which the bowl content is emptied in connection with an automated CIP procedure.
The discharge takes place at full speed without any interruption of feed of CIP liquids. The centrifuge is available with main connections as sanitary clamps and all other utility connections of clamp type.
The electric motor is suitable for variable frequency drive, which makes it possible to have bowl speeds down to 62% of the maximum bowl speed.
The design conforms to a number of EC directives, and the machine is made in accordance with the general directives for machinery. The machine is equipped with nozzles for flushing of the bowl top, the bowl bottom and the solids collecting chute.
