Detailed Equipment Introduction
Gain in-depth insights into Industrial Double-Door Sterilizer (Pass-Through Chamber) for Cleanroom Transfer equipment’s working principles, application scenarios, and technical highlights.
Product Introduction
In pharmaceutical cleanrooms, hospital CSSD units, and GMP food production lines, materials must move between controlled and uncontrolled zones without breaking the contamination barrier. The Double-Door Sterilizer (Pass-Through Chamber) addresses this challenge by combining an interlocked dual-door cabinet with three sterilization modes — UV-C 254nm, ozone, and optional 180°C dry heat — in a single SUS304 stainless steel enclosure. The interlock logic prevents both doors from opening simultaneously, protecting the cleanroom pressure cascade and ISO 14644 classification while materials transfer between zones.
Compared with a single-mode UV cabinet, the HSYL pass-through chamber lets operators choose the sterilization mode that fits the load: UV-C for surface decontamination of packaged goods, ozone for hard-to-reach crevices, and dry heat for heat-stable tools, glassware, and metal instruments. The unit is widely used in pharmaceutical GMP facilities, hospital sterile supply departments, biotechnology laboratories, cosmetic cleanrooms, and food processing plants that handle aseptic packaging or sensitive ingredients. For complete hygiene and sterilization workflow planning, the chamber can be integrated into a broader sanitation line that includes upstream washing and downstream controlled storage.

Working Process
- Load materials through the non-clean side door, then close and engage the interlock.
- Select sterilization mode on the microprocessor panel — UV-C duration, ozone cycle, or dry heat temperature profile.
- Run the cycle; the interlock holds both doors locked until the programmed exposure time and temperature are complete. For facilities integrating multiple thermal processes, a Tube Heat Exchanger can support adjacent heating or cooling stages in the same production line.
- Confirm cycle completion on the LED display, then open the clean-side door to retrieve sterilized materials. Perform a weekly UV lamp intensity check and quarterly HEPA filter inspection to maintain validated kill-rate performance.
Applications
- Pharmaceutical GMP cleanroom material transfer
- Hospital central sterile supply department (CSSD)
- Biotechnology and microbiology laboratories
- Cosmetic cleanroom pass-through between formulation and filling
- Food factory aseptic packaging material preparation
- Medical device and laboratory glassware decontamination
Advantages
- Triple-mode sterilization (UV-C 254nm, ozone, 180°C dry heat) in one SUS304 chamber — covers surface, gaseous, and thermal decontamination in a single unit.
- 99.9% kill rate against bacteria, viruses, and molds, validated to support GMP, FDA 21 CFR, and ISO 14644 compliance audits.
- Electronic or mechanical interlock prevents simultaneous door opening, protecting cleanroom pressure cascade and reducing cross-contamination risk during transfer.
- Optional H13/H14 HEPA filter removes ≥99.97% of particles at 0.3 μm, maintaining chamber air purity before and after each cycle.
- Adjustable UV exposure (1–60 min) and dry heat temperature profile let operators match cycle intensity to load type without over-exposing sensitive materials.
- SUS304 seamless interior with easy-wipe surface simplifies cleaning validation and supports repeatable hygiene workflows.
