RINA Serie 200

Vertical batch centrifuges with manual discharge

Simplicity, robustness and compactness.

The RINA Serie 200 models are vertical batch centrifuges with manual discharge dedicated to solid-liquid separation of slurries with high rotating speed (see table below).

Riera Nadeu accumulates experience in several processes of the following sectors: Pharmaceutical & Fine chemicals, Bulk chemicals, Waste treatment (nuclear and others) and more applications with the most demanding requirements.

These machines can be equipped with a filtering (“F” version) or decanting basket (“D” version) with a retention capacity of solids from 4 to 550 dm3.

The filtering version RINA 200F is being used when the solid in suspension shows a granulometry and a morphology forming a permeable cake inside the drilled basket.

The decanting version RINA 200D is working by settling the solid on the ferrule of the basket thanks to the difference of density with the liquid phase. The clarified liquid is extracted by overflowing inside the casing and/or with a manual skimmer.

In both cases, the discharge of solid is operated by opening the centrifuge and acting manually or with lifting means.

Those manual centrifuges are specially recommended for products requiring a variable residence time for spinning and intensive washing. They allow to process some products presenting difficulties to be scraped out or that cannot be re-suspended.

The design of those machines is thought for being easy to use, for versatility and for easy-maintenance.

From the safety point of view, they can be adapted to work in explosive hazardous area with the relevant certification or approval for the operating location.

Riera Nadeu supplies manufacturing in various types of material from the most basic steel to the most high-grade alloy.
