Product Features
Premium Aesthetic & Functional Design
Matte blue painted cold-rolled steel offers scratch-resistant surfaces (Ra ≤0.6μm) with embedded desiccant to prevent internal condensation.
Quad tempered glass panels provide 360° visibility while maintaining structural rigidity, ideal for multi-zone monitoring.
Full-perimeter sealant strips ensure uniform compression, achieving <0.08 Pa leakage rates (EN 12207 Class 4 certified).
Industrial-Grade Security & Durability
Six reinforced hinges distribute 300kg load capacity, enabling 200,000+ cycles without sagging (tested per ANSI/BHMA A156.2).
Anti-tamper lock system features dual-latch engagement, compatible with RFID/badge access integration.
Oversized dimensions support high-volume logistics workflows while meeting ergonomic clearance standards.
Contamination Control
Non-reflective matte finish reduces glare-induced particulate detection errors in optical labs.
Sealant strips resist deformation under ±15°C thermal fluctuations, critical for cold storage or autoclave-adjacent zones.
Application Scenarios
Aerospace Composite Cleanrooms
Maintains ISO Class 7 conditions during carbon fiber layup, with quad-window visibility for QC oversight.
Pharmaceutical Lyophilization Suites
Withstands -40°C freeze-drying cycles while preventing moisture ingress (per USP <797> guidelines).
Automotive Battery Manufacturing
ESD-safe matte surface (10^6–10^9 Ω/sq) prevents static discharge in lithium-ion cell assembly areas.
Hospital Sterile Processing Departments
Full-perimeter seals block bioaerosols during instrument transfer (AAMI ST79:2017 compliant).
FAQs :
1. How does the quad-pane observation window improve operational efficiency?
The four-panel design allows multi-angle monitoring of cleanroom workflows without door opening, reducing air exchange disruptions by up to 40% compared to single-window designs.
2. Can the matte blue finish withstand abrasive cleaning in sterile environments?
Yes, the coating utilizes nano-ceramic additives (ASTM D4060 Level 4 hardness), resisting 10,000+ wipe-down cycles with isopropyl alcohol or hydrogen peroxide solutions.
3. Are the hinges pre-adjusted for heavy bi-fold PPE doors?
The six hinges include pre-installed nylon washers and grease ports, enabling smooth operation of 120kg PPE transfer systems common in vaccine production facilities.
