Customization guide

Adjustable parameters include:

  • Material grade (SS304 vs. SS316L) to match chemical exposure and temperature demands.
  • Size/shape to fit tank dimensions (custom elliptical dimensions available).
  • Finish (electropolished or passivated) for enhanced hygiene or corrosion resistance.

Get inspired

Ideal for applications requiring rapid access to tanks while maintaining sterile conditions. For instance, pharmaceutical cleanrooms benefit from its seamless integration, while food processing plants appreciate its resistance to cleaning agents and high-pressure washdowns.

Supplier's note

  1. Three Breakthroughs:

    • The Pro Model’s dual-coated SS316L achieves 60% better corrosion resistance than SS304, enabling use in aggressive chemical environments.
    • Enhanced pressure tolerance (270 psi) in the Pro Model outperforms industry benchmarks by 20%, supporting high-pressure bioreactors.
    • Expanded temperature range (-50°C to 200°C) in Advanced/Pro models accommodates cryogenic and high-heat sterilization processes.

  2. Optimal Version Selection:

    • Base Model (SS304): Suitable for general food storage or low-pressure systems where cost-efficiency is prioritized.
    • Advanced Model (SS316): Ideal for pharmaceutical or dairy processing requiring moderate chemical resistance and pressure handling.
    • Pro Model: Recommended for industries like biotechnology or chemical manufacturing needing extreme durability (e.g., With SS316L’s triple corrosion resistance, you can safely handle sulfuric acid baths. Its 270 psi rating ensures reliability in high-pressure sterilization cycles).
