Rust eliminated with dry-film NSF H1 lubrication
Doubling chain life in stunning & bleeding conveyors
Initial situation
A leading European slaughterhouse operated stunning and bleeding conveyors (Stork) under wet and heavily cleaned conditions. Conventional oils were washed out during sanitation, resulting in:
- Chain corrosion and stiff movement after washdowns.
- Premature chain replacement (≈ 1.5 years average life).
- Grease washout on adjacent bearings in wet areas.
This led to recurring micro-stoppages, increased spare-part spend and hygiene/compliance pressure.
Solution
- Switched chain lubrication to Interflon Food Lube G220 dry film lubricant with MicPol® technology.
- Weekly relubrication on stunning conveyors to build and maintain a protective boundary film.
- Same product on bleeding conveyors with optimised dosing to avoid dripping.
- Where relevant, exposed bearings moved to Interflon Food Grease LT2 for better washdown resistance.
- Clean-in/clean-out: legacy residues removed and lubrication route & frequency logged for repeatability.
Compliance: All lubricants used are PFAS-free and NSF H1 certified (Halal & Kosher).
Results (measured & observed)
- Chain lifetime doubled: ≈ 1.5 → 3.0 years on stunning/bleeding lines.
- Rust almost eliminated on chain surfaces after washdowns; stiff operation noticeably reduced.
- Smoother running, with fewer post-washdown interventions.
- Reduced lubricant consumption
- On related infeed conveyors, relubrication interval extended from weekly → monthly after trial and checks.
Conclusion
Switching to a dry-film NSF H1 lubricant with MicPol® technology doubled chain lifetime, reduced rust-related stiffness and stabilised conveyor operation without drip risk. Optimised dosing and bearing upgrades further reduced maintenance load. The approach is repeatable, audit-ready and directly valuable to reliability and production KPIs.
