Road Transport Rail Transport Marine Transport Intermodal LogisticsThe Sigma Advantage
Unlike conventional lead-lined bromine containers, Sigma utilizes PVDF Roto-Lining technology developed and proven through more than a decade of bromine service experience. PVDF provides exceptional resistance to bromine and bromine derivatives while maintaining long-term lining integrity under demanding operating conditions.
The Proven Performance
- 10+ years of documented bromine service
- Field-proven technology
- Excellent resistance to bromine attack
- Resistant to bromine containing moisture and impurities
- Low permeation characteristics
- Minimal maintenance requirements
- Extended service life
Product Purity Protection
Traditional lead-lined containers may introduce contamination risks during long-term service. PVDF is chemically inert to bromine and bromine derivatives, helping maintain product purity while eliminating concerns associated with lead contamination.
Reduced Lifecycle Cost
The Sigma PVDF system is designed to reduce:
- Periodic lining repairs
- Maintenance interventions
- Downtime
- Inspection-related costs
- Lifecycle ownership costs
