The model RZR 2102 control is a 2-stage stirrer which holds speed constant under significant load changes such as sticky media like a polymers for example

• Choose between 2 options for gear setting and experience the power of the 100W output motor which allows for torque of 400 Ncm in an overload situation and 200 Ncm for continuous operation at speeds from 12 - 2000 rpm
• Calibrate your torque at the beginning or even during your process to monitor viscosity changes over time
• Speed control uses rheostat or interface
• Viscosity range up to 100000 mPa s

Computer Aided Lab Environment

Software Watch & Control
This software has been designed to run equipment for nine well known internatioinal manufacturers: Heidolph Instruments, Gerhard, Hettich, Ismatec, Julabo, Memmert, Mettler-Toledo, Prominent and WTW.

It is possible to run units at a time of either one or two different manufacturers.

Features for Heidolph electronic stirrers:

• Set speed (rpm)
• Set gear stage (#1 or #2)
• Register and save actual speed (rpm) and actual torques (Ncm) as a digital file
• Set speed can be programmed as a ramp

Profibus
Watch & Control is suitable for Profibus technology. Please call us for any of those components. Profibus Mastercard, Profibus Interface PBI, Interfache extension and Interfache cable.

Electronic Stirrers Overview
These models are ideal for any demanding stirring task in which the viscosity varies during the entire process either through reaction or due to mixing. Electronic stirrers maintain exact speed under changing load. The displayed torque gives information relating to the actual viscosity and all results are reproducible.

Stirrer line includes all standard features for safety, ease of use and Reduced Cost of Ownership plus:

Overhead Stirrers Overview
For Your Safety

• Important for continuous unattended operation:
• The motor will be switched off if a high thermal load situation occurs to increase safety in your lab and to preventatively avoid accidents
• Additional safety is provided by sparkless motors which reduce incidents in a volatile environment
• All models feature a smooth start operation which prevents spills and splashing media. The speed will ramp up slowly until your set rpm has been reached

• An optional shaft guard prevents any accidents involving contact with the impeller shaft running at high speeds
• Use an optional remote control via cable to start and stop your electronic stirrer outside a closed fume hood

For Your Ease of Use

• A through-shaft design allows for adjusting of the impeller position to make height adjustment more convenient for you
• Reduce your work time and yield excellent mixing results in challenging high viscosity media
• Optional software programs for all electronic stirrers aid you in automating your process and software saves all data in electronic files
• A single grip allows you to re-adjust the height of your stirrer on the optional telescope stand
• Due to the light weight design all set-ups in your lab are easy and fast
• Our clear and self-explanatory front panel layout is for your ease of operation
• Use your lab space efficiently: The slim and space saving design allows to fit into any glassware set-up nicely

Reduced Cost of Ownership

• Reduce your maintenance costs: The sealed housing protects your stirrer from aggresive fumes, liquids and vapors to prevent internal corrosion. This results in an increased lifespan of 10 years on average at a reduced maintenance and repair cost
• The high torque accounts for better mixing results in less time that reduces your process time and your work hours significantly
• Maintenance free motors reduce repairs and down times significantly to ensure years of continuous operation
• Patented impeller technology for demanding applications that mix gels and other similar media in shorter times which reduces process cost and work hours

inoJET Impellers: The all-rounder for thick and thin
Principle of Functionality
The worldwide patented inoJET® Mixing System from INOTEC GmbH is the result of the so-called-cone-principle. Turbulent flows are created at the taper end by acceleration, displacement and retardation. These flows advance through the stirred medium and result in the new dynamic mixing motion.

Application Examples
Worldwide the only impeller capable of completely mixing larger quantities of high-viscousity liquids and gels.

Fields of use include:

• Beverage production
• Dairy production
• Food, Sugar & Candy production
• Chemistry/Petrochemistry
• Ceramics
• Water treatment
• Cosmetics
• Cororant/Paint production
• Paper manufacture

• One system for literally all mixing tasks for low to high viscosity media
• Patented cone-principle creaties even at low speeds a turbulent flow which is unique to the VISCO JET®
• Even with high-viscousity media and gels which naturally do not mix by using common impellers you will observe an immediate flow through the entire beaker
• This technology allows for de-gassing of gels while preventing air-intake and foaming
• Reduce your process times significantly while performing the best mixing results ever
