Double-Door Electronic Interlock Pass Box | Cleanroom Contamination Control Solution

Product Description

Advanced Dual-Chamber Barrier Technology
Our Double-Door Electronic Interlock Pass-Through ensures zero cross-contamination during material transfer between controlled environments. The intelligent electronic interlock system prevents simultaneous door opening through sensor-based automation, while dual independent chambers create a physical isolation zone.

Featuring real-time status monitoring and configurable purge cycles (air shower/vacuum/UV), it maintains ISO 14644-1 compliance for critical sectors like pharmaceuticals and microelectronics. The robust 304 SS construction with seamless welds eliminates particle traps, and the intuitive HMI allows audit trail export for GMP documentation.

Typical Applications

• Pharma Labs
  Transfer vials between Grade B/C cleanrooms

• Biotech Facilities
  Sample movement in BSL-2/3 laboratories

• Electronics Manufacturing
  Wafer handling in semiconductor fabs (Class 100-1000)

• Hospitals
  Pharmacy-to-ward sterile supply transfer

• Food Production
  Raw material entry to HACCP zones

Frequently Asked Questions

Q1: How does the double-chamber design prevent cross-contamination compared to single-door pass boxes?
*A: Unlike conventional pass-throughs, our dual-chamber system creates a physical isolation zone between environments:

• Stage 1: Outer door opens → material enters first chamber → door seals

• Stage 2: Internal sensors validate cleanliness → inner door unlocks

• Critical Safeguard: Electronic interlock enforces <2% door overlap risk (per EN 12469) via infrared sensors.
  This sequential transfer protocol blocks >99.97% of airborne particles (tested per ISO 14644-3).*

Q2: What certifications support compliance with pharmaceutical regulations?
*A: The system is engineered for full traceability:

• GMP Compliance: Validatable per EU GMP Annex 1 (2022) & FDA 21 CFR Part 11 (electronic records)

• Safety Certificates: CE-marked with SIL-2 rated interlocks (IEC 61508)

• Material Traceability: 304 SS material certificates & EPDM gasket USP Class VI reports included

• Audit Support: HMI stores 25,000+ event logs with CSV export for regulatory audits.*

Q3: Can it integrate with existing cleanroom control systems?
*A: Yes, we offer flexible integration:

• Communication: Modbus RTU/TCP protocol for BAS/BMS connectivity

• Automation: Dry-contact signals for door status/errors to SCADA

• Customization: Optional pressure sensors (0-30 Pa) for differential pressure monitoring

• Upgrade Path: Firmware supports future ISO 14644-18:2022 updates.
