Brake systems require stable, high-pressure air supply under extreme duty cycles, without adding maintenance burden or integration complexity. The Sonceboz eCompressor delivers 15 bar and 400 lpm through high-efficiency oil-free scroll technology, eliminating emulsification risks while reducing TCO and downtime. Its 23 kg compact architecture integrates power electronics, liquid cooling, and CAN communication (AUTOSAR, ISO 26262 & ISO 21434 compliant), enabling seamless 500–1,000 V platform integration, optimized thermal management (<90°C discharge), and low-noise operation. The result: simplified vehicle architecture, secured functional safety, and reliable long-term braking performance in demanding commercial applications.
When braking performance is critical, reliability is not optional.

Heavy-duty electric vehicles still rely on uncompromised hydraulic capability, even as energy availability becomes a strategic constraint. The Sonceboz emPTO provides 80 kW of sustained output through a gearless transmission concept that minimizes losses and ensures exceptionally smooth operation. Its embedded control architecture combines power stage and software intelligence to deliver accurate torque management, real-time condition monitoring, and streamlined system validation. Engineered for platform flexibility, it integrates efficiently into diverse vehicle layouts while supporting long duty cycles and optimized energy distribution. The outcome: stable auxiliary performance, simplified development pathways, and dependable operation across the vehicle lifetime
