Description

RW 47 digital
Overhead Stirrers

Extremely powerful, mechanically controlled laboratory stirrer designed for highly viscous applications for quantities up to 200 l (H2O). It is suitable for intensive mixing for use in laboratories and pilot plants. The stirrer comes equipped with a protection for overheating of the motor by means of self-locking temperature limiter. Additionally, to secure bowls, a stirring shaft protection and clamping fixture are optionally available.
– Digital speed display
– Infinitely adjustable speed (57 – 1300 rpm) in two speed ranges
– Overload protection
– Error code display
– Robust, ergonomic design
– Quiet operation
– With constant power-drive
