Separation system for Pharmaceutical and Biotechnical applications BTAX 215 The BTAX centrifuge is specially designed for biotechnical processes such as cell harvesting, broth clarification and the separation of cell debris. The centrifuge has a very high separation efficiency and can be installed in a closed system. To ensure cleanliness, the BTAX can be heat pasteurised to 100oC. Available models The BTAX centrifuge is available in four versions • BTAX 215S-31 CEP Paring disc version. • BTAX 215S-31 CEFP Paring disc version, explosion protected. • BTAX 215H-31 CEP Hermetic version. • BTAX 215H-31 CEFP Hermetic version, explosion protected. All BTAX models are gastight. The complete system can be supplied in an explosion-protected version when required. Throughput capacity Actual throughput is in the range of 0-12 m3/h depending on paring disc size and design, as well as on the amount and type of solids in the feed, temperature, viscosity, required degree of clarification etc. Max hydraulic capacity of disc stack is much higher. Efficient solids ejection During separation, solids collect in pockets recessed in the bowl wall which avoids undesirable solids build-up, and minimizes disturbances during solids ejection. The pneumatically operated solids-ejecting system ensures fast and efficient discharges resulting in a clean bowl. Axial discharge channels lead from the solids pockets to valves, which are held closed by a spring loaded valve slide. To eject solids from the bowl during operation the slide is lowered momentarily by a very short injection of compressed air or gas through the hollow bowl spindle. This opens the valves and the solids are ejected. High separation efficiency The high speed of the bowl creates a peripheral centrifugal acceleration of 12,000 gravities. This gives the BTAX an extremely high separation efficiency that can capture particles down to 0.1 ì in diameter. Large solids space Long periods between ejections is possible thanks to the large (14 l) solids space, which results in better separation and drier solids. Paring disc design In this version the clarified liquid is continuously discharged under pressure by a paring disc, which is a stationary impeller that converts the rotational energy of the liquid into pressure. With the paring disc design there is no need for a downstream pump. Hermetic inlet and outlet The bowl is always completely filled with liquid in the hermetic version. This eliminates the risk for oxidation and airborne infections and ensures gentle treatment of the product.

Efficient cooling The frame hood and bowl casing are jacketed for cooling. When separated solids need to be cooled, a jacketed cyclone can be supplied. Totally contained system To protect both the product and environment, the BTAX 215 is provided with a special water cooled axial seal under the bowl to prevent contamination of the drive system. Sturdy frame and belt drive Power is transmitted from the vertically mounted motor to the spindle cartridge by the flat-belt drive inside the sturdy frame. The vertical bowl spindle which supports and drives the separator bowl is designed as a replaceable...
