Zeta magnetic agitators meet GMP production requirements

The open design of the magnetic impeller in particular permits the important perfect cleaning in place (CIP). This has been proved in independent studies carried out by the Swiss University in Wädenswil in accordance with the European Hygienic Engineering & Design Group (EHEDG), Total Organic Carbon (TOC) and Riboflavin methods. A further decisive feature is the design of the ceramic sleeve bearing, whose generous dimensions and material combination (silicon carbide on zirconium oxide) offer the longest possible operating lifetime. Wear and the release of unwanted particles are almost negligible owing to the hydrodynamic properties of the agitator blade and the patented ‘lift-off’ lubrication channels, the company says. These properties are also why BMR magnetic agitators are used more frequently in the foodstuffs industry – reduced exposure to germs and bacteria can extend the shelf life of the product. The units are available with a transmittable torque of 0.3–200Nm for tanks with a maximum stirred volume of up to 45,000 litres. The Zeta product range also includes magnetic agitators for bioreactors, mixing units, conventionally sealed agitators and defoaming units. www.zeta.com
