Cojali Viscous Fans, Air brake products and electronic components

COJALI is an European company that manufactures products and diagnosis for commercial vehicles.

COJALI, with more than 20 years of experience in the manufacture of spare parts for commercial vehicles, began with the production of viscous fan clutches, plastic blades, valves, servo clutches, etc. Then, there were just a few references being manufactured, however, the research was already becoming one of the most important pillars of the company. Year after year, this fast process is bearing excellent fruit, strengthening COJALI and JALTEST as reference brands in Europe, USA and the rest of the world.

COJALI, R+D+i at the service of commercial vehicles

Research, development and innovation are the foundations upon which COJALI is built. For this reason, each and every one of its products have been able to come to life; from fan clutches with electronic control, to valves with electro-pneumatic control, automatic levers, even the diagnosis tool and the new ECU for e-ABS trailers and semi-trailers. All of them were born in this department that comprises all the sections developed by COJALI.
