IKA Works Rw 47 Digital Overhead Stirrerika

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, a stirring shaft protection (R 303) and a clamping fixture (R 6547.1) to secure mixing vessels are available as accessories.

• 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
• SI 400 safety switch and SI 474 fixing device are available as optional accessories allowing the user to switch on the instrument only at a defined height in the stand’s working range

The device requires a 3-phase electricity supply and power cord (not included in scope of delivery) in order to operate. The connection of the unit to the power supply must be done by a qualified electrician. Wiring diagrams are included in the manual for reference.
