Presentation Pasteruizer Chain for Glass Bottles
2
Fortrex Pasteurizer chain
3
Fortrex Pasteurizer Chain
4
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
5
Fortrex Applications Products: Glass Bottles Glass Jars Steel Cans
6
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
7
Positrack guiding option suitable for DTS-C self clearing transfers Chain Features
8
Positrack ® Guiding System
9
Rolling friction reduces chain load by 60% Chain features
10
Chain Parts and Assembly
11
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
12
Rod retention
13
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
14
Option of static large diameter return ‘shaft’ The belt runs on the rollers Minimum diameter 6¼”/159mm Idler design
15
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 Design information

USP Material
17
What‘s new????
18
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
19
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
20
USP Material – What’s new??? Break Trough Advantages of USP
21
USP Material High temperature, Wet and dry environments FDA Approval Buoyant in water Temp. range 4 -104°C USP
