Stainless Steel MatTop chain Fortrex 9200
2
Fortrex ™ 9200 development Breakthrough Chain development for Tunnel Pasteurizers For High End applications: Long machines up to 141’ (43mtr) Wide machines up to 240” (6mtr) High % glass breakage High reliability / eliminate downtime High chemical resistance, including necker lubes Maximize conveyor chain life Dynamic in/outfeed Eliminate catenary elongation
3
End User Design specification
End-user wishes Eliminate unscheduled downtime High chemical resistance Resistance against glass breakage Simple belt guidance and catenary design: Less thermal and elastic expansion Strength and stiffness not dependent on temperature No absorption of necker-lube Visual inspection of belt possible Stainless steel belt with rollers
4
End User Design specification
Modularity of design remains important Installation and repair should be similar to plastic modular belts Ability to use Positrack® guiding lugs Ability to use Classic & DTS-C self-clearing transfers Pasteurizer design very similar to plastic modular belts No welding on belt Low wear of hinges due to bushes Less pitch elongation Easier to get pins out of older belt

7
Chain width Chain width from 9” up to 240”in 3” increments
The width indicates the effective chain width. The total chain width is always 0.75” wider because of rod retention 0,375” (9,5mm) extra on both sides

13
Rollers to reduce load/friction
Reduce friction chain – wearstrips by 60% Reduction in motorpower/gearbox Reduction in shaft size & centre bearings Ultra smooth running / no chain pulsation
14
Roller options Fortrex 9217 Fortrex 9227 Fortrex 9237 Rollers every 3”
Retrofits in tunnel pasteurizers equipped with Chevron wearstrips Rollers every 6” Suitable for new pasteurizers with 6” parallel wearstrip layout Rollers every 12” Suitable for new pasteurizers with 12” parallel wearstrip layout
15
Positrack® chain guiding
Fortrex can be equipped with Positrack® tracking guide which provides centre tracking through the whole length of the machine This ensures that the chain can never run against the inside wall of the tunnel pasteurizer (no catching / jamming) Optional tracking guide Fits on centre of belt
16
Positrack® chain guiding
Positrack runs on 40mm straigh profile in the centre of the machine
17
Drive sprockets Conventional split drive sprockets
2” wide tooth profile for low Suitable for shaft 90mm, 120mm, 3,5” round and square shafts Sprockets are fixed on the shaft 14 tooth, pd: 10.1” (257mm), shaft drop: 4,7” (118,4mm)
18
Drive sprockets Conventional split idler drums 2” wide
For 90”mm, 120mm, 3,5” round and square (others upon request) Optional to use a static return system
19
Fortrex in/outfeed transfers combs
Classic combs are available for classic in/outfeed transfers sections Fingercombs made out of Reinforced Polymer
20
Fortrex DTS-C in/outfeed transfers
DTS-C transfer plates in combination with 7705 DTS chain enables the in- outfeed transfers to be self-clearing from Ø50mm

Fortrex™ Testing Programm
26
Extensive testing programm
Glass testing programm Drive sprocket engagement Idler system (where glass collects) Outfeed finger transfers
27
Extensive testing program
Fortrex offers a highly reliable conveyor chain for pasteurizers Fortrex is designed for Strength in the specific pasteurizer conditions. No degrading in strength with elevated temperatures. No degrading in strength during lifecycle of machine. No degrading in strength when chemicals are applied
28

Specific benefits Fortrex belts
OEM High end solution with respect to tunnel pasteurizer reliablity Retrofits to existing machine made easy Very narrow tunnel due to reduction of catenary sag Classic drive shaft arrangements End User Highest reliability during lifetime of the pasteurizer Elimination of unscheduled downtime Dynamic in/outfeed bottle transfers Superior (dis)-assembly of belt Reduction in maintenance
33
Total Cost of Ownership / theory
34
Total Cost of Ownership / practice
Eliminate cost of unscheduled downtime creates significant savings and improves productivity Based on a single deck pasteurizer running bottles/hr with an unscheduled downtime taking 72 hours to repair 60.000 x €0,40 x 72 = € Bottles/hr Cost of distribution loss per product Lost hours due to Downtime Cost elimination of a single downtime
35
Pasteurizer Retrofits
36
Retrofit to Fortrex™ / USP MatTop
From To: Plastic MatTop Fortrex Stainless Steel MatTop ++ Walking Beam + Wiremesh Not recommended
37
Retrofitting to Fortrex™
With Retrofit focus on following items: Carry way Chevron wearstrips can accomdate Fortrex 9217 series Parrallel wearstrip can accomdate 9227/9237 depending on the Pitch of wearstrips Return part Static rollers covered with plastic or rotating rollers are OK Drive shaft Classic drive shaft can accomdate Fortrex drive sprockets (machined according to the required shaft diameter) Idler shaft Classic idler shaft can accomdate Fortrex idler drums (machined according to the required shaft diameter) Transfer combs Classic Fortrex combs suitable for any retrofit
38
Fortrex™ can run on Chevron/Inline
Fortrex 9217 Suitable for Chevron retrofit Chevron wearstrips Parallel wearstrips
39
Retrofitting to Fortrex™
For Retrofits it is recommended to involve an experienced OEM. Our Application engineering Team is very experienced to supply all data for succesfull retrofit.
