Our technical department consists of a modern equipped structure, able to develop confidentially also customised solutions. We use CAD stations for design and creation of new components and Fan extractors. As well the prototypes are ready, all the electrical tests, according the required standards, are performed. the prototypes are tested in the most critical conditions of their real use. For example the fan extractor is acted into a sample cooker Hood, over Stoves on fire with boiling water: in these conditions we submit the motor to a thermal test. If the test results are fulfilled, we go ahead testing the performances: With a VENTURI measuring station we are able to measure the airflow in m3/h, and the air pressure in mmH2O. Finally, Before going in range, a technical report, certifies the results.
