Product Description

How does it work

The G140 Pre-Crush compactor is simple in its operation, a large heavy-duty sliding door at the end of the compactor closes to form a pre-crush chamber. This allows the material to be crushed inside the machine a number of times to reduce its volume substantially. Once the volume is reduced, the door is then opened and the crushed waste is ejected into a regular 20 or 40ft container attached to the end of the compactor. This machine has been built to comply with the same CHEM  standards as the other machines in our static compactor range, meaning any compactor container can be used.

What is the advantage

The Pre Crush will ensure that there is uniform compaction throughout the waste stream, in other words, all of the waste is well compacted before it goes into the container.

All memory of the shape of an object is obliterated by the G140 Pre-Crush compactor, it indiscriminately will crush anything put inside it. This means that bulky items will take up much less space. This is particularly beneficial with items such as sofas or wardrobes which typically would have posed a problem for waste disposal.

With greater compaction efficiency than a conventional static  compactor, it is possible to get more waste into a given size of the container. A real-world example is a council in County Antrim that previously had 2 collections per day for its waste wood containers. After installing the Pre Crush they have reduced this down to one collection every 5 days, resulting in massive savings on collection services. Meaning that in this instance the compactor will pay for itself in under 18 months.

Machine could pay for itself in under 2 years
