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
