Supply, service, calibrate (UKAS) and support a wide range of industrial mixing and laboratory equipment.

Zanelli Testing Laboratory

Zanelli offer the possibility to trial your products at pilot/small production scale to verify correct specification of mixing equipment.

The new TEST CENTER ZANELLI at Customer’s service is equipped with laboratory machines having small capacity up to pilot machines that can deal with small-scale production of products with low, medium and high viscosity. Our attention is focused on the aim of reproducing in scale, as far as possible, the functional features and structural properties of industrial size machines. The machines available in the TEST CENTER ZANELLI are equipped with instruments for monitoring and data detection such as: temperature probes, vacuum pump, over pressure, heating/cooling of mixing vessel, variable speed of the tools, etc.. all managed by a supervision system that allows us to collect all the data and the trends of the values during the tests. After completing the tests, results, obtained from the tests carried out, are examined together with the Customer and with the help of our Technical Department, that has an established experience, we are able to calculate which is the most suitable production machine or plant according to Customer’s needs in terms of technical and economical issues.

THERMOGRAPHIC ANALYSIS OF MECHANICAL AND ELECTRICAL PARTS
Thermographic analysis with high definition infrared camera, industrial type, in order to identify dthe distribution of the temperature in different parts of the machine. In the field of ATEX classification, the compliance to maximum surface temperatures shall ensure compliance to the Standards. The distribution inside the electrical cabinets allows identification of possible overloads of components or lines finalized to predict future failures.
