Building upon all the advantages of traditional pass-through windows, the introduction of an electronic intelligent control system provides a more reliable, intuitive, and manageable material transfer solution.
I. Core Functions: Intelligent Control and Safety Assurance
1. Absolute Safety and Zonal Isolation
Working Principle: Utilizes a microprocessor-controlled, electronically interlocked system. Electrical signals control electromagnetic locks, ensuring that when one door is open, the electromagnetic lock on the opposite door is de-energized and locked, making it absolutely impossible to open both simultaneously.
Customer Value: Provides more reliable isolation assurance than mechanical interlocks, effectively preventing cross-contamination caused by air convection. It acts as an intelligent barrier for maintaining cleanroom pressure differentials and cleanliness standards.
2. Mandatory Process Management
Working Principle: Implements a "close one door before opening the other" forced logic. The control system will only supply power to the electromagnetic lock of the other door, allowing it to open, after one door is fully closed.
Customer Value: Technically eliminates the risk of personnel accidentally opening both doors due to negligence. Enforces cleanroom procedures through intelligent means, enhancing management standardization.
3. Clear Status Indication and Alerts
Working Principle: Equipped with three-color indicator lights (Red/Yellow/Green) and a buzzer. Red indicates "Door Not Closed" or "In Use", Green indicates "Ready to Open", Yellow can indicate "Self-Cleaning in Progress" (if equipped), and the buzzer sounds an alarm if a door is not properly sealed.
Customer Value:
Clear Visibility from a Distance: Operators can clearly judge the status of the pass-through from afar, improving operational efficiency and accuracy.
Instant Alerts: Promptly reminds personnel to close the door securely, avoiding unintended compromise of the cleanroom environment due to oversight.
II. Materials and Performance: The Perfect Blend of Intelligence and Durability
We insist on using high-quality materials for key components to ensure long-term, stable operation in clean environments.
| Component | Primary Materials & Characteristics | Core Advantages |
| Chassis | SUS 304 Stainless Steel (Primary Recommendation) | Corrosion-resistant, dust-free, easy to clean and disinfect. Fully meets material requirements for regulations like GMP, ensuring long service life. |
| Quality Cold-Rolled Steel Plate (Electrostatically Painted) | A cost-effective and practical choice with a smooth, rust and scratch-resistant surface. Suitable for cost-sensitive applications with slightly lower environmental requirements. | |
| Doors | Same material as the chassis, sliding design, with tempered glass view window. | Good sealing, stable operation. The view window allows for visual inspection of contents. Combined with status lights, it offers an enhanced user experience. |
| Interlock System | Core Component. Electronic electromagnetic locks, controlled by an intelligent control board. | Rapid response, strong locking force, stable operation. The foundation for achieving the intelligent interlock function. |
| Sealing Gasket | Silicone Rubber or EPDM Rubber | Excellent sealing, aging resistance, ensures chamber airtightness, effectively preventing air leakage. |
| Control System | Microprocessor-based intelligent control board, integrates status indicator lights and operation buttons. | Stable functionality, customizable interlock logic. It is the "intelligent brain" of the pass-through. |
Key Performance Characteristics:
Intelligent & Reliable: Electronic interlock logic eliminates human error, making management easier.
High Sealing Performance: High-quality sealing gaskets and precise construction ensure excellent chamber airtightness.
Robust & Durable: Selection of premium materials guarantees long-term, stable performance in clean environments.
User-Friendly Interaction: Audio-visual alarms and status indicators reduce operational errors.
