Meritor WABCO to supply electrically controlled air dryer to OEM

Meritor WABCO Vehicle Control Systems has announced the release of Electrically Controlled Air Dryers (ECAD) for use on a major OEM's trucks beginning in late February. ECAD is a robust, highly developed air processing system and meets increased requirements for processed system air.

ECAD offers a number of advantages compared to conventional air dryer systems. Its electric air dryer includes two solenoid valves which facilitates pressure control and regeneration. To control ECAD, the vehicle's electric control unit (ECU) compiles relevant information for air drying, such as line pressure, engine speed, engine operating time, road speed and ambient temperature. With intelligent regeneration control, intermediate regenerations take place during long delivery cycles and are determined by delivered air volume. Regeneration takes place from the system reservoir volume, with no separate regeneration reservoir required.

The benefits of ECAD include:

  • Intelligent compressor control and drying
  • Monitoring of dryer working cycles and flow rate
  • Cartridge change requirement detected and displayed on control panel
  • Potential fuel savings can be achieved using ECAD when combined with control software
  • Lower service cost

"At Meritor WABCO, we take extreme pride in customer relationships and are honored that ECAD has been chosen by a major OEM," said Rick Romer, director of Key Customer Management, Meritor WABCO. "It reemphasizes our company's leadership in air dryers and their importance on improving heavy-duty vehicle efficiency for our customers."
