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 slack adjusters, even the Jaltest Diagnostics Equipment, the new ECU for e-ABS  and the latest Telematics Projects.


The appropriate facilities in accordance to COJALI’s turnover

The facilities where COJALI is located are divided into several areas:


  • Some are focused on manufacturing, such as the automated manufacturing assembly lines for cooling and braking systems, the electronics laboratory, the diagnostics preparation workstation, etc.

  • Others are focused on development, such as the departments for the implementation of vehicle systems for diagnostics, the design centers of cooling and braking systems.

  • Other departments are entrusted to the quality control, raw material or the finished product, for cooling systems, valves, servo clutches, brake chambers, automatic slack adjusters, even test benches for the testing of the Jaltest diagnostics tool or the ECUs.

  • Others are in charge of the commercial management, marketing and administration.


Not only a manufacturer. COJALI services.

And finally, a series of specific sections responsible for meeting the needs of our customers. All of them constitute the added value which differentiates us from our competitors:


  • Training: COJALI has developed a series of classrooms aimed at a theoretical and practical training. They offer training cycles of each and every one of the skills which are necessary in order to cope with the technological developments arising currently. Among them, we can find diagnosis, electricity and electronics, pneumatics, engine management, gearboxes and retarders, etc.

  • Technical Assistance: The technical assistance staff is a large team in charge of solving any incidents that our customers may encounter.

  • Customer Service: Telephone or on-road support are the two types of assistance that the COJALI group can offer. Both of them carry out a series of tasks providing information, advice or guidance in order to ensure that our customers have satisfactory business relations.

COJALI, innovating for more than 25 years.

COJALI, Mother Company of the COJALI Group, was born in 1991 with the goal of providing a technological boost to all the aspects of spare parts for commercial vehicles. With this goal, it began its journey with the manufacturing and development of cooling systems, braking systems, servo clutches and automatic slack adjusters of original quality, that is, an alternative product with equal or better performance than the original product.

This spirit of innovation makes its growth exponential and, in the following years, it will expand the references mentioned above, increasing the ranges of our products, including viscous fan clutches, fan clutches with bimetallic control, valves with electro-pneumatic control, etc.

Consecutively, new goals are being achieved, one of them was the achievement of regulation ISO 9001:2000 (Quality Management System) certified by IQ-Net (The International Certificate Network). Immediately, the technological projects of the Jaltest Diagnostics Equipment are addressed or, for instance, the viscous fan clutches with electronic control.

A few years later, the Jaltest Diagnostics was launched, along with a complete plan that includes training and technical assistance. Nowadays, we are still committed to this plan because since then, it has been a distinguishing factor and has turned Jaltest into the most important Multi-brand Diagnosis Global Solution for Commercial Vehicles in the European continent.

The viscous fan clutches with electronic control appears along with other developments within the scope of electronics. This is yet another of the important points of the R+D+i department which is reasserted thanks to the UNE 166002 R+D+i Management system certification awarded by the Spanish Association for Standardization and Certification (AENOR).

In this regard, the electronics laboratory has been created, responsible for the design and development of brake components with electronic control such as the e-ABS ECU for trailers and semi-trailers. In addition to many other developments such as the reconditioning of ECUs and EBS and ABS modules.

Currently, COJALI is a brand established in more than 95 countries all over the world, and this brings the confidence and commitment that ourproducts have the highest guarantee and quality, and this is certified by COJALI.
