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
