Energy efficiency waste extraction upgrade against the clock

When Impacts project team were challenged with the gauntlet of replacing a twin extraction system at Greenshires in a 24-hour shutdown they knew they had a challenge. After many years of suffering unreliability of an environmentally unfriendly waste system, Greenshires - Leicester, had no option but to replace it with the latest extraction system solutions. Impact Air Systems were called to the table.

After careful planning, Greenshires production manager and Impacts project team agreed that the existing system would need to be dismantled and replaced within a 24 hour period.  A challenge that Impacts senior project manager Glenn Mills relished.

The plan was to completely replace all the equipment outside consisting of two new Waste Fans, Rotary separator, Diverter Drop chute, Twin Compactors and a Reverse Jet Filter.  A complete new control panel was also installed during the shutdown period.

The old system compromised of balance fans and did not include a Filter.  This meant that the existing system was not only a noise issue for the neighbours but was also discharging dust fibres over the surrounding area.

The new system consisted of the latest separation device, a ‘Rotary separator' which also allows the inclusion of a fully automatic Reverse jet Filter.  The conveying air is now guided into the dust filter, cleaned and then returned back into the factory via ‘summer / winter' diverter valve.

This upgrade now ensures that no dust is omitted to atmosphere and the warm conveying air can be recycled back into the factory.  Two major environmental benefits and a must for Greenshires to ensure they keep their ISO14001 certificate.

Jonathon Green (Greenshires production manager) said, ‘the installation of the new system has had a huge benefit for the business, not only has production increased due to a reliable system but the cleanliness of the waste area is now second to none, Normally an area you want to hide is now a place you want to promote rather'.  

‘Working with Impact & Casepak has been rewarding, their commitment to install a quality system without disrupting our production far exceeded our expectations'.
