Description
Special features
A specially designed variable frequency drive (VFD) system provides benefits that include low starting current, and a short-time power supply (UPS). The UPS helps the control system to stop the separator in a controlled fashion to avoid damage and product loss in case of external power failure. The special geometry of the bowl ensures gentler acceleration for shear-sensitive agglomerates and particles. Combined with a new patented disc stack design (1), these significant improvements of the fluid dynamics lead to maximum separation efficiency, at the same time as reducing power consumption.
The CLARA 200 is also equipped with Oxy-Stop (2), a hydro hermetic seal that ensures minimal oxygen pick-up. CLARA 200 can also be equipped with a seal mechanism that makes it possible to clarify sparkling wines under pressure. The centrifuge has a built-in paring disc for the separated product, eliminating the need for an external pump.
The top part of the frame and the frame hood are jacketed for cooling and sound dampening. The sliding bowl bottom is fitted with an easily exchangeable erosion liner for protection against possible abrasive solids.
Standard design
This mobile unit consists of a stainless steel skid fitted with a disc stack centrifuge and all the auxiliary equipment needed for a safe, efficient operation. This includes:
- Feed valve that is automatically closed when not in production mode
- Sight glasses at both in- and outlet
- Sample valves at both in- and outlet
- Flow meter – Pressure indicator at outlet
- Regulating valve at the outlet for back pressure adjustment
- A Variable Frequency Drive (VFD)
The VFD also has a built-in control panel to monitor and control the CLARA 200 unit. The control panel displays information about the operation, such as operating mode and time to next discharge. It also displays alarm messages. The disc stack centrifuge consists of a frame that has a horizontal drive shaft, worm gear, lubricating oil bath and vertical spindle in the lower part.
The bowl is mounted on top of the spindle, inside the space formed by the upper part of the frame, the solids collecting cover and the frame hood. The feed and liquid discharge system also rests on this structure.
All metallic parts that come in contact with the process liquid are made of high-grade stainless steel. Liquid-wetted rubber gaskets are made of FDA-compliant nitrile rubber. The frame hood and the solids collecting cover are cooled with water to minimize any temperature increase in the process medium, and also to act as a sound dampener.
