Getting the most from Energy Crops

The products described here provide a package that delivers the ultimate in the protection of energy crops, each one making significant contributions to the stability, longevity and performance of all clamped silages.

SilaPactor

At 3 metres wide and weighing approximately 4,000kg with 11 individual roller rings, the SilaPactor can increase dry matter compaction density by up to 40% when compared to conventional tractor rolling. Better compaction means less air in the clamp, improved fermentation and better use of clamp space. Fewer passes are needed over the clamp resulting in significant time savings and lower fuel costs. 

Perfect for all silages above 25% DM, the SilaPactor helps to ensure that air pockets, which allow the growth of harmful bacteria, yeasts and moulds, are minimised. Significantly better use of available clamp capacity eases demands on valuable storage space. Conventional compaction methods result in typical silage densities of 180-220kg DM/m3, whereas SilaPactor users can expect densities of up to 310kg DM/m3.

SilaPactor benefits:

  • Increase silage compaction by up to 40%

  • Make fewer passes: less fuel, less time

  • Compact right to the edges of the clamp

  • Reduce DM losses

  • Improve silage quality

Feedstock Preservatives 

Proven products to conserve digestible organic dry matter, optimize energy potential and ensure unbeatable aerobic stability.

O2 Barrier 2in1

Available exclusively from Kelvin Cave Ltd O2 Barrier 2in1 is a combined polyethylene silage film and polyamide vacuum film just 100µm thick which separates into two on the clamp. It offers more effective clamp sealing with reduced workload and up to a ten-fold increase in oxygen barrier compared to conventional polyethylene silage sheeting.   

The two films separate automatically shortly after the sheet is laid on the silage surface and the polyamide vacuum film is sucked down onto the surface of the silage to form an airtight seal. Up to 40% lighter than conventional sheeting systems O2 Barrier 2in1 is easier to handle, and recycling and disposal costs are reduced.

See our O2 Barrier 2in1 page for more details.

ClampNet

ClampNet, exclusively from Kelvin Cave Ltd, is a 300g/m2 heavy-duty green silage cover with seamed, stitched edges to prevent fraying or unravelling. ClampNet is reusable and features reinforced loops to enable the secure attachment of gravel bags, allowing more weight to be focussed on the shoulders of the clamp.

As well as offering protection from birds and mammals, ClampNet helps to reduce spoilage and maintain good compaction of the clamp, preventing air pockets from forming.

See our ClampNet page for more details.

ClampTiles

ClampTiles are the ideal alternative to tyres for weighting down silage sheets. Made from 90% recycled material and with a life expectancy of around 15 years, ClampTiles are easy to handle and can be stacked on pallets when not in use, saving valuable storage space. And, unlike tyres, they won’t harbour rainwater and debris.

See our ClampTiles page for more details.

ClampFilm

ClampFilm is a cost effective 40-micron primary silage sheet that is spread directly on top of the silage, covered with conventional black plastic and weighted down. As the air in the clamp is used up the lightweight, flexible ClampFilm is sucked down onto the surface of the silage forming a perfect air-tight seal.
