These Stirrers are specially designed brushless AC variable speed stirrers driven by frequency inverter to ensure reproducible speed with any load. Model RQ-140/D-FP is with flame proof motor & frequency inverter inside flameproof enclosure, suitable for use in Group II A & II B hazardous areas.
These stirrers have steady & constant speed for viscous materials and solutions that change viscosity during mixing. It has built in digital RPM indicator for process validation and reproducibility.
Facility for pre-setting of stirring speed in increments of 10 RPM
Digital display of stirring speed within the range of 10% to 100% (+100 RPM)
