Electronically Controlled Air Dryer (ECAD)
WABCO is well-known for its robust, highly developed air processing systems. The Electrically Controlled Air Dryer (ECAD) has been developed to meet the increased requirements for processed system air. ECAD shows one of the possibilities for future air processing. ECAD is electrically controlled via the vehicle's electronic control unit (ECU). It completes WABCO's range of market leading air dryers, which also includes electronic air dryers with integrated electronic control (Electronic Air Processing Unit E-APU).
Features
- Pressure control and regeneration function via two solenoid valves, controlled by the vehicle ECU
- To control ECAD, the vehicle ECU evaluates relevant information, e.g. system pressure, engine speed and air supply
- System pressure adjusted individually via the vehicle ECU, e.g. single device for cut-off pressure 8.5 bar and 12.5 bar
- Regeneration takes place from the system reservoir volume: no separate regeneration reservoir is required
- Intelligent regeneration control:
- Intermediate regenerations takes place during long delivery cycles
- Regeneration determined by delivered air volume
Benefits
- Intelligent compressor control
- Intelligent drying
- Monitoring of dryer working cycles and flow rate
- Cartridge change requirement detected and displayed on a control panel
- Low service cost
Application
- Trucks: heavy, medium
- Buses
Market availability: Africa, Asia, Europe, North America, South America
