Strong Stronger HEM 841 Z 

The HEM 841 Z is the largest PTO chipper from JENZ. The machine is designed for large tractors with an output of 244 to 544 hp. Thanks to its wide intake of 1.40 m, particularly bulky material can be distributed wider and flatter on the table. This leads to better cutting geometry and easier running of the drum, which increases the wood chip quality enormously.

Designed for mass, the HEM 841 Z has an unbeatable throughput. This means that several jobs can be completed in a short time, the machine and the tractor can be used to capacity all year round and operating costs can be kept low.

Epsilon S100F101

JENZ chippers are equipped with a Palfinger Epsilon crane as standard, because they are robust and easy to maintain. Thanks to professional solutions, EPSILON cranes increase the chipper's productivity and allow the operator to fully concentrate on chipping. The S100F101 crane has a 10 m reach to be able to reach material that is further away. The optional splitter is used for any larger logs. As a result, no material is left unprocessed.

Hydraulic discharge

The hydraulic fan can be controlled continuously and independently of the speed of the chipping rotor and can therefore optimally adapt to operating conditions. This ensures more even chip discharge and reduces the load on the hydraulic system. The reduced fan speed reduces the abrasion on the wood chips, which lowers the fines content.

easyChange 
maintenance system

The hydraulic screen basket cover of the HEM 841 Z allows quick and easy access to the rotor. With the push of a button, the cover is opened without having to be screwed on or off. The screen basket can then be changed by crane, as it is freely accessible in the rotor cover. This makes manual lifting and carrying of the screen basket a thing of the past.


Everything needed for maintenance on the rotor is in the optional professional swivel toolbox located directly on the rotor. Included are an air connection, light and useful tools. Maintenance work is facilitated by the sufficient freedom of movement in the screen basket cover.

Uniquely good

JENZ wood chipper are the ideal choice for companies that value economy, ease of use and flexibility. The chippers are fuel-efficient and take the burden off the driver thanks to ergonomic cab concepts and intelligent maintenance and control solutions.

 

easy2advanced
 Control System 

The new easy2advanced machine control system is a comprehensive update of the familiar easy2 control system. It supports the driver with active feedback, enables flexible, user-orientated settings and ensures a reliable crop flow. This allows the machine to be used even more productively and efficiently.  

D1.2
Drum

Whether fine or coarse chips, the robust D1.2 cutting drum convinces with outstanding chip quality. The regrindable blades enable maximum economy and operational reliability. In addition, the high inertia of the D1.2 ensures very smooth running. This not only protects the drive train, but also leads to improved chip quality.

CFA
Draw-in Control System

The CFA and CFA2 intake controls automatically adjust the intake speed to ensure that the chipper is utilised evenly and in a way that is gentle on the machine, and that the wood chips are of optimum quality. CFA adjusts the infeed speed depending on the rotor speed. CFA2 adjusts the infeed speed depending on the opening angle of the upper roller.

DIP 
Roller Pressure System

Due to the variable pre-load pressure of the upper roller, the chipper can adapt to any material. Shrub trimming, for example, requires a higher pressure, while logs are fed in almost without pressure. Thanks to its easy adjustment to respective requirements, the chipper works efficiently and achieves a consistent output.

Efficient screening technology

The innovative screen baskets reliably prevent excessive lengths with a minimum of fine particles. This is particularly noticeable in the processing of cut shrubbery, where the wood is often drawn in crosswise.
Available sizes: 
S (private heating systems) 
 M (medium-sized heating systems)
NEW: L (large-sized heating systems, Combined heat and power plants)
 XL (Combined heat and power plants)

Smart 
Hydraulic

The CFA and CFA 2 intake control systems forward material-dependent information to the easy2 control system. The intelligent JENZ Smart Hydraulic system quickly and sensitively adjusts the intake speed. In addition, top roller pressure and the maximum intake speed can be set by the operator at the push of a button.

IPS Impact Protection System

With the IPS (Impact Protection System), sensors detect inadmissible vibrations caused by foreign bodies such as stones or iron parts. The system activates a protection programme that, for example, stops material discharge in 0.8 seconds. This protects the machine from expensive consequential damage and reduces unplanned downtime to a minimum.

Additional 
screen basket

Changing orders mean changing demands on wood chips. The additional screen basket on the screen basket cover facilitates incredible flexibility. The screen basket is simply changed by crane. Lifting and carrying by hand is not necessary.
