Air Conditioning
Air Conditioning
The Zetros interior remains comfortable – no matter what the weather outside. Drivers can concentrate on the task at hand, even in extreme climates such as deserts and permafrost regions
- Powerful heating and ventilation system
- Optional air conditioning
- Optional auxiliary water heater
- Optional additional heat insulation
Automatic cut-outs
Automatic cut-outs: easier operation and faster troubleshooting.
Automatic cut-outs are fitted ex-works, instead of the standard blade-type fuses. After an overload, or after the fault has been remedied, the cut-outs are reactivated simply by throwing the switch. This simplifies operation, since you no longer need to exchange fuses or keep a wide range of blade-type fuses on hand. The fuse affected can be seen from the switch position, making troubleshooting much faster, too.
Axles and Wheels
Axles and Wheels
The cast-steel planetary axles are extraordinarily robust, allowing high axle loads. Moreover, Zetros comes with a spare wheel of equal quality to the standard wheels fitted to the vehicle ex-works. The spare is securely stored in a space-saving and easily-accessible location
- Axle suspension based on parabolic springs
- Axle articulation of 2 x 500 mm along diagonal
Body mounting options
