Features |
| Woodchipper |
| Own hydraulic cooling system (using Venturi airflow) |
| Integrated blowing system which, in combination with Venturi blowing system guarantees a powerfull airstream |
| No nonsense machine; chipping at the front, discharge at the back. |
| No jacks or accelarator needed, which otherwise shatters good woodchips. |
| This prevents unneccassary wear, saves power and therefore fuel, resulting in higher efficiency |
| Greentec drum woodchippers stand for uniform chips with low particulate percentage |
| Drum |
| Knives distributed along the drum. Drum with blower blades on both sides. |
| Widia bottom knive placed below cutting knive, easy accessible |
| Exterior wall of drum is 15 mm thick and main axe Ø100 mm |
| Specially designed anvil knife, small branches are cut at a differente angle, resulting in better chipping quality. |
| Infeed |
| Lowered table for bottom roller providing more space for wood clamp to insert thick logs |
| Upper infeed roller on both sides driven by heavy torq engines with embedded oil bearings (low maintenance) |
| Bottom roller driven by heavy engine with embedded oiled bearings (low maintenance) |
| Screenunit |
| Venturi discharge chute can be tilted hydraulically, for easy replacing of the sieve unit |
| Quality |
| All machines are manufactured out of premium steel 355 (52-3) |
| Teeth on infeed rollers are made of hardwearing Hardox steel, guaranteeing agressive infeed for years |
| Discharge chute, bottom between infeed roller and anvil knife beneath the drum equipped with replacable wear plate made of hardwearing Hardox steel |
| Machines are made of durable materials, including bearings, hydraulic valves, engines, pumps and more |
| After sandblasting machines are double powder coated |
| Servicing |
| Knives are easy accessible, under a hinged cover, on the top of the machine. |
| Drum is easily secured for changing knives. |
| Anvil knife adjustable, and can be used four times |

GCS control – Greentec Control System
- Compact touchscreen control.
- Programs for different wood types.
- In these programs different parameters are adaptable. Pressure down at top roller, starting and stopping speed of the no stress, either or not reversing of the infeed rollers and infeed speed.
- Easy switch to low engine speed to reduce fuel consumption and noise. This gives coarse wood chips with even lower fine percentage.
- Chip size and wood type adjustable at any time.
- Stopping and if needed short reversing of the infeed responds not only to speed, but also to working pressure of the system.
- GCS control box compact design with stainless steel casing.
- Vulcanised controllers without moving parts, less chance of error.
- In these programs different parameters are adaptable. Pressure down at top roller, starting and stopping speed of the no stress, either or not reversing of the infeed rollers and infeed speed.
- Exclusive on Ufkes Greentec machines.
- Least possible electronics (relay, cables and more), operational reliability.
- Minimum cables on the machine, only Canbus signal with plus and minus.
- Minimal chance of errors
- Waterproof up to IP67.
- 5 languages available; Dutch/English/French/German/Polish.
