For thirty years Presona of Sweden have been producing automatic balers that are renowned for their innovative features and enviable robustness. Hundreds have been installed throughout the world - including even Russia where they know a thing or two about rugged plant.

Unlike many competitors that use a shear method, Presona incorporate a pre-press system that reduces wear, saves energy and makes for quiet operation. See the diagram on the right.

The latest development uses proportional hydraulic valves whereby the accelerating ram decelerates as pressure is applied, reducing stress, noise and increasing the life of all components.

All Presona machines have been made in Sweden except for the recent LP50 horizontal baler designed and manufactured in Somerset. Because the Presona engineers recognised that our design and manufacturing was equal to theirs, this machine also carries the Presona badge. We're rather proud of that.

Breaking the code Not all the Presona range is shown on the website: with 18 models to choose from it would only confuse you (and us). Code letters after the model number, ie LP50 VH refer to the hopper size. In addition most models are also available with either larger or doubled up motors for higher output, ie EH1 or EH2. The benefit to you is that the correct capacity Presona can be installed to cope with your needs. Hopper sizes are therefore:   EH 1250 x 1100mm     VH 1500 x 1100mm     CH 1650 x 1100mm     DH 2050 x 1100mm   KW or HP? We have adopted Continental practice in giving power in kw, divide by ¾, ie 75kw is 100hp.

Presona Prepress Baler

1. Prepress and main press in starting positions. The press chamber is full.

2. The prepress presses the material to be baled into the chamber.

3. The main ram compresses the material using it's maximum pressure. The feeding conveyer continues to load material onto the top of the baler prepress.

4. When the bale has reached the preset length the wiring operation starts. The main ram continues to operate.

5. The prepress opens and the material stacked on top falls into the baling chamber.
