Celeros APD centrifuge technology
Why select the Celeros APD centrifuge over other options?
Due to the inherently flexible design, the Celeros APD centrifuge is very compatible with many separation and clarification processes that frequently challenge the biotech industry. Typical applications include cell harvesting and debris removal, microbial processing, vaccine manufacturing, and blood plasma fractionation.
Its simple internal arrangement permits easy cleaning and sterilization of all process wetted components including the centrifuge bowl, piston, and casing. The Celeros APD centrifuge does not require internal stress baffles or scrapers, which commonly compromise solids discharge and CIP efficiency.
The Celeros Model APD centrifuges can be cart mounted for easy mobility or rigid frame mounted for permanent installations. Each system is equipped with a PLC and AC drive to afford extremely flexible processing and easy facility adaptation.
Compared to Disc Stack centrifuges, the Celeros APD centrifuge:
- Does not have internal conical discs that can plug up.
- Does not have solids discharge ports or piston mechanisms to plug or fatigue.
- Offers reduced internal components ensuring far more efficient CIP and SIP sequences.
- Is far less sensitive to abrasive wear.
- Is lower installed cost due to its simple design.
Depending on the process, the Celeros Model APD provides dry paste and clear centrate. In fact, the Celeros Model APD can achieve over 35X concentration factor, where disc stack centrifuges typically achieve less than 10X. This ability to concentrate benefits the customer by:
- Reducing the burden of downstream liquid handling
- Improving productivity by reducing the process duration
- Increased product throughput
- Overall lower operating cost
Compared to other high speed solid bowl & tubular bowl centrifuges, the novel Celeros APD centrifuge bowl configuration:
- Offers compete, automatic discharge of sticky pastes in a contained manner.
- Provides a low shear feed cone to gently accelerate the feed stream, and a submerged centrate zone to further reduce shear force applied to the process.
- Does not require internal stress baffles or scrapers, which commonly compromise solids discharge and CIP efficiency.
How it works.
The inner workings of the Celeros APD centrifuge are both technically brilliant and elegantly simple. Explore an interactive presentation describing the basic operation of the Celeros APD centrifuge.
Depending on the specific application, the Model APD centrifugal separation system can be equipped with a variety of ancillary components. However, as indicated below, the basics of the centrifuge are very similar.
The main elements of the Celeros Model APD continuous flow centrifuge are:
- A centrifuge bowl that spins at speeds sufficient to generate 20,000 x G at the bowl inside diameter.
- An axial motion piston for discharging accumulated solids.
- A sealed containment case with a compartment and discharge nozzle for the centrate, and a solids valve and discharge nozzle to secure residual liquid.
- PLC control systems and a variable speed electric drive.

How to get the best performance from your Celeros APD centrifuge.
Exact performance of separation equipment can vary greatly. Performance relates to many process and application factors, the most important of which are; the actual materials to be separated, their density and concentration and the operational settings of feed rate, rotation speeds and spin times. Accessory equipment like pumps and mixers can also influence the performance of the Celeros APD centrifuge. Varying process parameters can yield different performance from batch-to-batch or even within the same batch run.
