Electronic Stirrers RZR 2020 and RZR 2021These models are ideal for any demanding stirring task in which the viscosity varies duringthe entire process either through reaction or due to mixing. Electronic stirrers maintain exactspeed under changing load. The displayed torque gives information relating to the actualviscosity and all results are reproducible.For Standard ApplicationsBoth RZR 2051 control and RZR 2052 control are 1-gear stage stirrers which hold speed constant under changing loads.Stirrer line includes premium safety standards and features for superior ease of use and reduced cost of ownership, plus:RZR 2051 control:• Accepts torque of 40 Ncm in an overload situation and20 Ncm for continuous operation at speeds from50 – 2,000 rpm. Viscosity range up to 10,000 mPa sAll electronic stirrers accept 200 % peak overload for alimited period of time. Your process therefore will notbe interrupted in short-term overload and similarconditionsRZR 2052 control:• Accepts torque of 180 Ncm in an overload situation and90 Ncm for continuous operation at speeds from30 – 1,000 rpm. Viscosity range up to 40,000 mPa s• Speed control uses rheostat or interfaceCalibrate your torque at the beginning or even during yourprocess to monitor viscosity changes.

ImpellersSelection parameters:Propeller-Type ImpellerPrecise working with an overhead stirrer depends on theright choice of the stirrer tool. When choosing a stirrer toolyou have to consider its different characteristics and theireffects. For example, the flow which the tool causes in themedium, the tool´s adequate field of application dependingon the speed range, and the execution of the tool accordingto the viscosity it is destined for.Application examples:1. Gassing of liquids < 500 mPa s: Radial Flow Impeller2. Homogenizing and suspending in liquids < 500 mPa s:Propeller-Type or Blade Impeller3.
