Component Specifications

Definition
A specialized fluid distribution system consisting of precisely engineered nozzles and ducts designed to deliver decontamination agents (such as hydrogen peroxide vapor, chlorine dioxide, or other sterilants) uniformly throughout an isolator chamber. This system ensures controlled flow rates, optimal droplet size distribution, and complete coverage for effective surface decontamination while maintaining isolator integrity through sealed connections and corrosion-resistant materials.
Working Principle
Utilizes pressurized fluid delivery through calibrated nozzles that atomize decontamination agents into fine mists or vapors, distributed via ducts to ensure uniform coverage. Nozzles employ Bernoulli's principle and Venturi effects to create optimal droplet sizes, while ducts maintain laminar flow patterns to prevent dead zones and ensure complete chamber saturation.
Materials
316L stainless steel (primary), PTFE/PFA lining, silicone gaskets, borosilicate glass viewports, Hastelloy C-276 for corrosive agents
Technical Parameters
  • Flow Rate 0.5-10 L/min per nozzle
  • Leak Rate < 1×10⁻⁶ mbar·L/s
  • Duct Diameter 25-100 mm
  • Pressure Range 2-8 bar
  • Surface Finish Ra ≤ 0.8 μm
  • Temperature Range -20°C to 150°C
  • Nozzle Orifice Size 0.1-0.5 mm
Standards
ISO 14644-7, ISO 13408-6, DIN 25408, ASME BPE

Engineering Analysis

Risks & Mitigation
  • Nozzle clogging from particulate contamination
  • Duct corrosion from aggressive sterilants
  • Incomplete coverage due to improper nozzle placement
  • Leakage at connection points compromising isolator integrity
FMEA Triads
Trigger: Particulate contamination in fluid supply
Failure: Nozzle clogging leading to uneven distribution
Mitigation: Install 0.2 μm filters upstream, implement regular flushing protocols, use filtered compressed air for cleaning
Trigger: Material incompatibility with decontamination agents
Failure: Corrosion and pitting of ducts leading to leaks
Mitigation: Use 316L stainless steel with PTFE lining, conduct material compatibility testing, implement corrosion monitoring program
