Overhead Stirrers

The overhead stirrers of the Hei-TORQUE series are perfectly designed for powerful stirring, in order to achieve best mixing results even for very challenging applications.

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

If you decide on our overhead mixers additional safety is provided by sparkless motors which reduce incidents in a volatile environment.

The speed of our lab agitator is adjustable over a large scale from 10 – 2,000 rpm.

Sealed housing of our overhead agitator complies with the high protection class IP 54 an guarantees longevity and maintenance-free 24 hour operation in aggressive environment.

The lab stirrers stand for longevity in challenging. Environments and for powerful stirring at minimum noise level – below 50 db. If demanding overhead agitators for any demanding stirring, our laboratory agitators line includes all standard features for safety, ease of use and reduced cost of ownership.

The laboratory stirrers of the Hei-TORQUE series features a high torque level of up to 400 Ncm and a number of unique features like a Quick-Chuck and a slide touch panel.

Standard Stirring Tasks

Hei-TORQUE Value 100/200 & 400 – Ideal for standard stirring tasks, they are deigned to mix and disperse media that require non-reproducible results in high-viscosity applications.

  • Indication of torque tendencies to monitor viscosity changes
  • Digital 2.4″ display for ease of operation
  • Constant speed even under changing loads
  • Safe start and stop of operation via slide touch panel to avoid unintended stirring
  • Newest motor generation for maximum power at minimum noise level
  • Unique Quick-Chuck for convenient impeller changes without tools

For Simple Mixing Tasks – For media up to 40,000 mPa’s and volumes up to 20L

  • The model is suitable for torque up to 100 Ncm at a power of 18 W
  • Slim design fits nicely into your research environment
  • A manual scale for speed adjustments for 35 – 2,200 rpm
  • A 2-gear stage design allows for high torque at various speeds and provides excellent mixing in short terms.

Hei-TORQUE Core – Lightweight for big tasks

The compact design allows for integration in closed systems, such as fume hoods, reactors, or production systems. Suitable for low- to medium-viscosity media up to 25 l.

The large diameter of the chuck (10 mm) allows you to use even large impellers and VISCO JET® tools. This facilitates a wide variety of applications, such as homogenization, dispersing, the dissolving of agglomerates, and more.

  • Torque up to 40Ncm
  • Speed range up to 2,000 rpm
  • Viscosity up to 10,000 mPas
  • Control knob for rotation speed, pushing starts or stops the function
  • Timer
  • “Max” button for short-term operation at maximum speed

Range of Performance – 40Ncm
