PT 7100

Stand dispersion unit for pilot plant


Drive Unit incl. high frequency three phase motor 1.5kW and frequency inverter for speed control (with display, main switch and potentiometer), with electricalstand (230V) and H-Foot base from anodized aluminum, CH type J (SEV1011) power cable

This POLYTRON® is ideal for applications up to 40 liters and for users who need to scale up from research and development to pilot plant or small production scale processes. The aggregate is one of the most important elements when scaling up. This unit has a great deal of versatility in the size and numbers of aggregates that can be successfully used with it. It can accommodate both the smaller laboratory aggregates and the larger ones used for pilot plant and small production applications. This permits the direct comparison of results between the smaller and larger aggregates which makes the scale up decision much easier.


– Application volumes up to 50 liters
– 2000 Watt motor provides sufficient power and high speed necessary for efficient particle size reduction
– Digital motor speed control with closed loop control from 500 to 12 000 rpm 
– Aggregate tip speeds up to 34 m/s produce the finest particles possible
– Available with electrical stand for easy raising and lowering of motor
– Soft start prevents splashing of homogenate from sample vessel
– Integrated overheating, overload and generator blocking protection
– Constant rotational speed regardless of load changes
– Aggregate replacement using one-handed quick-release coupling 
– Insulated motor housing keeps motor noise to a safe, approved level during operation
– Various models of dispersing aggregates which are Easy-to-Clean and  designed for many different applications
