Powerful Stirring

  • A through-shaft design allows for adjusting the impeller position to make height adjustments more convenient
  • All electronic stirrers accept 200 per cent peak overload for a limited period of time without interrupting the process. Your process therefore will not be interrupted in short-term overload and similar conditions.
  • Reduce process times by utilizing patented VISCO JET® impellers for mixing gels and other challenging media with ease
  • The motor will be switched off if a high thermal load situation occurs to provide operator safety
  • Sealed housing guarantees longevity and maintenance-free 24-hour operation in an aggressive environment
  • Calibrate your torque at the beginning or even during your process to monitor viscosity changes. Reproducible results made easy
  • Set your speed of choice on the self-explanatory panel or via digital interface from 30 - 2,000 rpm
  • Enhanced bright digital display for torque and speed
  • Constant speed under changing loads over the entire span of every gear setting
  • Shipment includes a 10-mm chuck as a standard

RZR 2051 control and RZR 2052 control - For standard applications
Both RZR 2051 control and RZR 2052 control are 1-gear stage stirrers which hold speed constant under changing loads

RZR 2051 control:

  • Accepts torque of 40Ncm in an overload situation and 20Ncm for continuous operation at speeds from 50rpm to 2000rpm.
  • Viscosity range up to 10000mPa s

RZR 2052 control: Accepts torque of 180Ncm in an overload situation and 90Ncm for continuous operation at speeds from 30rpm to 1000rpm.

  • Viscosity range up to 40000mPa s
  • Speed control uses rheostat or interface
  • Enhanced bright digital display for torque and speed

RZR 2102 control and RZR 2102 control Z - For high viscosity
Both models RZR 2102 control and RZR 2102 control Z are 2-gear stage stirrers which hold speed constant under significant load changes such as sticky media like polymers

  • Choose between 2 options for gear setting and experience the power of the 100W output motor which allows for torque of 400Ncm in an overload situation and 200Ncm for continuous operation at speeds from 12rpm to 2000rpm
  • Speed control uses rheostat or interface
  • Viscosity range up to 100000mPa s

RZR 2102 control Z - For high viscosity
Features identical technical specifications as the RZR 2102 control except for:

  • Speed: 4rpm to 540rpm
  • Torque: 800Ncm in an overload situation, 700Ncm at continuous operation
  • An additionally flanged planet gear for extreme viscosities up to 350000mPa s

The RZR 2102 control Z does not feature the through-shaft design for impeller adjustment
