Take me directly to Our products

COJALI, innovating for more than 25 years.

COJALI, mother company of the COJALI Group, was stablished with the goal of providing a technological boost to all the aspects of commercial vehicle components. With this goal, it began its journey with the manufacturing and development of Cooling systems, Air Brake 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 Diagnostics Solution for Commercial Vehicles worldwide.

Our Electronic Control fan clutch program is developed within the scope of electronics. This is yet another important milestone for COJALI’s 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 and is 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 105 countries all over the world, and this brings the confidence and commitment that our products have the highest guarantee and quality, and this is certified by COJALI.
