PresentationPasteruizer Chain for Glass
Bottles
Fortrex Pasteurizer chain
Fortrex Pasteurizer Chain
Fortrex Pasteurizer Chain
• Breakthrough development for Tunnel pasteurizers
• 3 year development time• For High end application:
• Long machines (Plan for 90 Meter long ongoing)
• Heavy Loads
• High % glass breakage
• High reliability of the tunnel pasteurizer
• Superior service cycle
Fortrex Applications
• Products:
• Glass Bottles
• Glass Jars
• Steel Cans
• 10 year life expected (needs to be approved and checked from case to case)
• Stainless steel modular chain• No thermal elongation (same as pasteurizer
construction)• Very little elastic elongation / catenary• High chemical resistance
Chain Features
• Positrack guiding option suitable for DTS-C self clearing transfers
Chain Features
Chain Features
• Positrack® Guiding System
• Rolling friction reduces chain load by 60%
Chain features
Chain Parts and Assembly
• Pitch 2.25”• Link Thickness – 1.04”• Link Material – SS 304• Pin Material – 204Cu• Roller Material – Special Polyamid (Not water absorbing)• Rollers connected to link when pins are removed• Pin Keeper Construction – SS304 metal gate with SS
rivets• Chain Available in 3 inch width increments
Chain Properties
Rod retention
Sprocket features
• Follows Rexnord drive design
− allows elongation >3% Follows Rexnord
− does not need a large catenary or tensioners• Wide tooth profile: low contact pressure• Idler drums/wheels preferred for return shaft
• Option of static large diameter return ‘shaft’• The belt runs on the rollers• Minimum diameter 6¼”/159mm
Idler design
• Carryway options:• Straight stainless profiles (no plastic wearstrips)• Chevron wearstrips (rollers in every bracket)• Positrack® guiding system
• Return way options:• Flat bed with 1 catenary (2 rollers)• Rollers (stainless steel with roller or slide bearing)• Self cleaning guide shoe
with rolling friction

What‘s new????
USP Material – What do we know?
• Life of plastic belts in pasteurizers is getting shorter:
• Legislation more tough (legionnaires disease in UK)
• Chlorine levels chosen too high by end-user
• No joint cooperation OEM ↔ Rexnord ↔ End user ↔
water treatment chemicals suppliers : results in wrong
chemicals chosen
USP Material – What do we know?
• Chemical degradation is identical to aging of plastics:
• Analogy: UV-light ages plastic window frames• Happens to all plastics always: only the speed can be
influenced• Many factors have an influence on the speed of the
degradation:• Temperature• Type of chemicals used• Time of exposure• Concentration levels• Combination of chemicals• Load on the chain
• and you can never control all of them
USP Material – What’s new???
• Break Trough Advantages of USP
USP Material
• High temperature, • Wet and dry environments• FDA Approval• Buoyant in water• Temp. range 4 -104°C
