Improve your engine performance with LEMA Viscous Coupling Units

The new LEMA high-efficiency viscous coupling units are the ideal solution for optimising engine cooling in the latest generation of vehicles.
Thanks to our experience in precision components, we offer a product that combines reliability, efficiency and innovation.

Advanced technology for intelligent thermal control

Designed to meet the needs of modern engine systems, LEMA visco-drive couplings use a variable viscosity fluid to dynamically regulate fan speed, adapting in real time to the engine's thermal conditions.

The main advantages:

- Active temperature regulation for optimal cooling at all times

- Less mechanical stress on engine components

- Reduced fuel consumption and pollutant emissions

- Optimised power transfer in AWD (All-Wheel Drive) systems


Tested reliability. Continuous performance.

Made with high-quality materials and subjected to rigorous endurance testing, LEMA viscous couplings ensure durability and consistent performance even under extreme operating conditions.
