IKA Overhead Stirrer RW 28 digital

Powerful, mechanically controlled laboratory stirrer designed for highly viscous applications for quantities up to 80 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 from 60 to 1400 rpm in two speed ranges � Push-through agitator shafts � Overload protection � Error code display � Robust, ergonomic design � Quiet operation � With constant power-drive Technical Specification: Stirring quantity max. per stirring position (H2O) 80 l Motor rating input 220 W Motor rating output 94 W Speed display LED Speed range 60 - 1400 rpm Viscosity max. 50000 mPas Output max. at stirring shaft 90 W Permissible ON time 100 % Torque max. at stirring shaft 900 Ncm Torque max. at stirring shaft at 60 1/min (overload) 1144 Ncm Torque max. at stirring shaft at 100 1/min 900 Ncm Torque max. at stirring shaft at 1.000 1/min 86 Ncm torque I max. 900 Ncm torque II max. 300 Ncm Speed range I (50 Hz) 60 - 400 rpm Speed range II (50 Hz) 240 - 1400 rpm Speed range I (60 Hz) 72 - 480 rpm Speed range II (60 Hz) 288 - 1680 rpm Speed control stepless Setting accuracy speed 1 �rpm deviation of speed measurement 10 �rpm Stirring element fastening chuck Chuck range min. diameter 1 mm Chuck range max. diameter 10 mm Hollow shaft, inner diameter 10.5 mm Hollow shaft (push-through - when stopped) yes Fastening on stand extension arm Extension arm diameter 16 mm Extension arm length 145 mm Torque display no Nominal torque 9 Nm housing material alu-cast coating / thermoplastic polymer clean room qualified no explosion proofed no Noise without element 62.5 dB(A) Dimensions (W x H x D) 123 x 364 x 252 mm Weight 7.5 kg Permissible ambient temperature 5 - 40 �C Permissible relative humidity 80 % Protection class according to DIN EN 60529 IP 40 RS 232 interface no USB interface no Analog output no Voltage 220 - 240 / 115 / 100 V Frequency 50/60 Hz Power input 200 W
