Case will unveil seven new models Tier 4 Interim-powered C Series crawler excavator range at Intermat 2012. The advanced low emission engines and Case Intelligent Hydraulic System lead to a 10% fuel efficiency improvement over B Series models.

The CX130C, CX160C, CX180C, CX210C, CX210C Long Reach, CX470C and CX470C ME excavators deliver improved digging performance with lower emissions and reduced consumption. Five new energy saving systems contribute to a substantial cut in operating costs for customers, with revised boom design leading to an increase in productivity and durability.

Efficient Engine Technology
The Tier 4 Interim compliant engines in the seven machines use cooled exhaust gas recirculation (CEGR) to provide a cleaner burn. Customers with B Series models will have already seen up to a 20% fuel improvement over older models and some competitors. With the C Series excavators they can expect up to a further 10% efficiency improvement.

The Case Intelligent Hydraulic System incorporates five energy saving systems. Boom Energy Save lowers engine revs during boom lower and swing operations, while the Auto Energy Save system cuts engine revs when the joystick control levers are inactive.

Swing Relief Control manages the hydraulic power distribution at the start of a slewing operation to provide the most efficient use of hydraulic flow and pressure. Spool Stroke Control automatically adjusts the hydraulic pressure during digging operations.  Lastly, Idle Shutdown turns the engine off after a preset time has elapsed.
