Radiation Protection Automatic Sliding Hermetic Door
Radiation Protection Automatic Sliding Hermetic Door integrates three core functions: radiation shielding, cleanroom hermetic airtight sealing, touch-free automatic sliding operation. It is specially customized for medical sterile radiation departments that require both radiation isolation and high cleanliness, such as laminar radiology operating rooms, sterile CT examination rooms, nuclear medicine preparation zones, and medical device radioactive testing labs.
Ordinary cleanroom hermetic doors lack anti-radiation shielding layers, while traditional manual lead doors cannot maintain airtightness for cleanrooms. This product embeds integral lead sheet inside the flush door leaf, matched with cam inward sinking airtight structure, perfectly solving dual demands of radiation shielding and sterile dust-free environment.
Two main types: single sliding radiation door for narrow personnel passages; bi-part double sliding radiation door for wide passages to move CT beds, surgical trolleys and medical equipment.
Main Material & Structural Composition
1. Door Leaf Radiation Shielding Structure
- Outer Panel
Standard: Antibacterial coated galvanized steel; Premium upgrade: SUS304 stainless steel, seamless flush chamfer design without dust dead corners, resistant to repeated hydrogen peroxide and alcohol disinfection.
- Radiation Shielding Core Layer (Core Feature)
High-density pure lead sheet, standard lead equivalent options: 1mmpb, 2mmpb, 3mmpb, 4mmpb, 5mmpb, customized according to equipment radiation intensity (DR/CT/DSA/nuclear medicine). Lead plate fully covers the entire door leaf without gaps, vertical lead overlapping at door seam to avoid radiation leakage.
- Inner Core Filler
Aluminum honeycomb lightweight filling, reduces overall door weight while guaranteeing flatness and noise insulation; fireproof rock wool core optional for fire separation requirements.
- Flush Observation Lead Glass Window
Double-layer hollow radiation-proof lead glass, matching the same lead equivalent as door leaf, fully embedded flush with door surface, no radiation leakage gaps, convenient real-time observation of internal equipment operation.
2. Hermetic Airtight Sealing System (Cleanroom GMP Standard)
- Full surrounding continuous aging-resistant EPDM foam compression gasket;
- Automatic drop-down silicone bottom seal strip, drops 10–15mm after door fully closes to block floor air gaps;
- Door leaf sinks inward 8–12mm when locked to compress all gaskets evenly, low air leakage rate, stably maintain cleanroom positive pressure gradient;
- Top full-enclosed stainless steel track housing, sliding mechanism installed on non-clean side, no dust accumulation grooves inside sterile radiation zones.
3. Automatic Drive & Touchless Control System
- Silent Brushless DC Variable Frequency Motor
Soft start & soft stop, low running noise ≤55dB(A), adjustable opening speed 250–550mm/s, long service life over 1 million opening cycles. Equipped with power failure manual emergency unlocking crank.
- Multi Touch-Free Trigger Modes
Microwave radar sensor, foot infrared induction switch; RFID card / facial recognition access control optional for medical personnel management.
- Multi-Layer Safety Protection
Full-height vertical infrared anti-pinch light curtain, door auto reverse when blocked to prevent trolley/ personnel clamping injury; red emergency stop button on control box.
- Optional Dual Electronic Interlock Function
Interlocked with adjacent clean zone doors or radiation room inner/outer doors, only one door can be opened at a time, avoid simultaneous opening causing radiation leakage and cleanroom cross-contamination.
4. Lead Shield Seam Anti-Leakage Treatment
Core Product Advantages
- Dual Function: Radiation Shielding + GMP Hermetic Cleanroom Performance
Integrates lead radiation isolation and full airtight sealing, one door meets radiation safety and sterile dust-free standards, avoids separate installation of lead door and cleanroom partition, saves project cost and space.
- Touch-Free Automatic Sliding Design
No manual push-pull heavy lead door, reduces staff labor intensity; horizontal sliding without swing radius, convenient for passing medical beds, CT trolleys and large inspection equipment.
- Zero Radiation Leakage Overall Shielding
Whole door leaf, window, frame and door seam all equipped with matching lead equivalent shielding layers, overlapping lead baffle eliminates radiation weak points, meets national medical radiation protection acceptance standards.
- Sanitary Flush Crevice-Free Construction
Seamless chamfered panel surface without dust hidden gaps, suitable for daily disinfection and wiping in sterile radiology operating rooms, compliant with EU GMP Annex 1.
- Modular Customization Matching Different Radiation Grades
Multiple lead equivalent thickness options, single/double sliding sizes, stainless steel upgrade, interlock and fireproof functions optional, fully matched with hospital cleanroom sandwich panel wall systems.
Typical Application Scenarios
- Medical Hospital: Laminar flow radiology operating room, sterile CT/DR/DSA examination room, nuclear medicine sterile preparation lab, interventional radiology clean buffer airlock
- Medical Device Factory: Radioactive component testing clean workshop, radiation medical equipment sterile assembly room
- Biotech Labs: Radioactive reagent sterile testing isolation room, low-dose gamma ray experimental clean booth
