ZF eCALM Pneumatic Cab Suspension

ZF's ongoing development of the CALM module has led to the electronically controlled eCALM, a pneumatic cabin suspension.

• Reduced energy consumption due to use of new electronic control unit
• Entire air system (compressor, accumulator, drier) can be designed to be smaller and lighter in weight
• Compressor can also be operated electrically by integrating it into the suspension system which means it actuates based on need
• Can generate air suspension in driver's cab in vehicles without a centralized compressed air system
• Includes new features such as leveling, lowering and raising cabin to different levels
• Ergonomic driving with slope compensation offers additional benefits such as access to difficult-to-reach components in the service position 
• Can be combined with ZF’s semi-active CDC damper system to maximize drive comfort
