Leading Safety Standards I Superior Ease of Use I Reduced Cost of Ownership

Leading Safety Standards • The electronic stirrers feature individual setting of the start operation, which prevents spills and splashing media. The speed ramps up slowly until your set rpm has been reached • An optional shaft guard prevents accidents • Non-sparking motors for additional safety • Important for continuous operation: the motor will be switched off if a high thermal load situation occurs to increase safety in your lab and to prevent accidents • Safe start and stop of operation via slide touch panel to avoid accidental start-up • To protect your stirrer against corrosion and...

Superior Ease of Use • No more misplacing and searching for • A through-shaft design allows for • Reduce your work time and achieve the chuck key! Immediate and convenient ”one-hand“ impeller changing with the Quick-Chuck - without any tools precise documentation of process cycles • Free Hei-Control software for all Hei-TORQUE Precision models aids you with automating your process, and saves all data in electronic files • Newest motor generation for maximum power at minimum noise level below 50 dB • All stirrers maintain exact speed under adjusting the impeller position to make height...

O Powerful stirring YOUR ADVANTAGES • An overtemperature sensor preventively shuts off the unit in dangerous heat-up situations -particularly valuable for you in case of unattended continuous operation • All units are designed for continuous 24-hour operation - including challenging high viscosity applications in polymer research • The durable design of the Hei-TORQUE series promotes longevity in an aggressive environment: The sealed housing protects against corrosion, ensures years of maintenance-free operation and complies with the high protection class IP 54 Powerful Stirring Leading...

Hei-TORQUE Value Hei-TORQUE Precision These stirrers are ideal for standard stirring tasks. They are designed to mix and disperse media that require non-reproducible results in high-viscosity applications These stirrers are ideal for demanding tasks which have to be reproducible and documentable. The huge number of additional features and operation modes allow for perfect adjustment to your individual application Accurate torque indication shows any viscosity changes Rotation direction change at Hei-TORQUE Precision 100/200 models Constant speed even under changing loads Digital 3.2”...

The differentiation between performance and features enables you to easily configure the right stirrer for your specific application Hei-TORQUE Precision Basic models The reliable solution for all standard applications that do not need documentation Hei-TORQUE Value 100 Hei-TORQUE Precision 100 High-end models The professional stirrer for demanding tasks: several options for individual settings as ramps and interval operation. USB and RS 232 interfaces allow for documentation and reproducibility, e.g. with the free Hei-Control software (for up to four devices) Drehzahl (U/min) Hei-TORQUE...

O Impellers Selection parameters Operational guidelines Precise working with an overhead stirrer depends on the right choice of the stirrer toot. When choosing a stirrer toot you have to consider its different characteristics and their effects. For example, the flow which the toot causes in the medium, the toot's adequate field of application depending on the speed range, and the execution of the toot according to the viscosity it is destined for Application examples: • Gassing of liquids < 500 mPa s: Radial Flow Impetter • Homogenizing and suspending in tiquids < 500 mPa s: Propetter-Type...
