IKA Overhead Stirrer RW 47 digital Overhead Stirrer

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 Technical Specification: Stirring quantity max. per stirring position (H2O) 200 l Motor rating input 490 W Motor rating output 370 W Motor principle three-phase current Speed display LED Speed range 69 - 1560 rpm Viscosity max. 100000 mPas Output max. at stirring shaft 300 W Permissible ON time 100 % Torque max. at stirring shaft 3000 Ncm Torque max. at stirring shaft at 60 1/min (overload) 4642 Ncm Torque max. at stirring shaft at 100 1/min 3000 Ncm Torque max. at stirring shaft at 1.000 1/min 285 Ncm torque I max. 3000 Ncm torque II max. 620 Ncm Speed range I (60 Hz) 69 - 330 rpm Speed range II (60 Hz) 330 - 1560 rpm Speed control stepless Setting accuracy speed 1 �rpm deviation of speed measurement 10 �rpm Stirring element fastening chuck Chuck range min. diameter 3 mm Chuck range max. diameter 16 mm Hollow shaft, inner diameter 13 mm Hollow shaft (push-through - when stopped) no Fastening on stand flange Torque display no Nominal torque 30 Nm housing material alu-cast coating / thermoplastic polymer clean room qualified no explosion proofed no Dimensions (W x H x D) 145 x 465 x 358 mm Weight 16 kg Permissible ambient temperature 5 - 40 �C Permissible relative humidity 80 % Protection class according to DIN EN 60529 IP 54 RS 232 interface no USB interface no Analog output no Voltage 3 x 400 / 3 x 230 V Frequency 60 Hz Power input 490 W
