Double-Door Electronic Interlock Pass Box | Cleanroom Contamination Control Solution
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 Pharmaceutical industry and microelectronics. The robust 304 SS construction with seamless welds eliminates particle traps, and the intuitive HMI allows audit trail export for GMP documentation.
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 airborne particles.
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.
(Note: Provide cleanroom class & PLC type for pre-configuration)
