KACO has started series production of its new generation of pressure compensation elements, developed to provide reliable housing ventilation for electric drive systems used in electric vehicles (EVs).
Electric drive units experience significant temperature and pressure fluctuations during operation, which can create fine oil mist and condensation. These factors often cause deposits on the diaphragms of conventional pressure compensation systems, leading to clogging and reduced function.
The new KACO design separates valve functions to keep the membrane clear of oil mist while maintaining continuous ventilation and effective protection against water and dirt. This ensures stable performance and extends the service life of electric drive systems, contributing to greater durability and reliability in EV propulsion units.
Key features include:
- Active pressure equalization during temperature and altitude changes
- A permanently clear membrane resistant to clogging by oil or dirt
- Oil and water-repellent materials with optimized geometry
- Protection ratings of IP6K4, IP6K7, and IP6K9 for harsh environments
- Scalable system design with variants for different load requirements
The development combines a reliable, non-clogging structure with high environmental resistance, making it well-suited for use in demanding EV and industrial applications.
