Modular Cleanroom Doors
Hardwall Hinged Doors
Single-leaf (900mm width) and double-leaf (1500-1800mm width) configurations. Stainless steel 304 frames with vision panels. Typical applications: personnel access in ISO 7-8 areas. Air leakage: ≤1.0 L/s·m² @ 50 Pa. Deiiang™ hinged doors feature reinforced frames capable of withstanding 500,000 operational cycles.
Sliding Doors
Automatic (0.8-1.2 m/s opening speed) and manual variants. Trackless systems preferred for minimal particulate generation. Example: Deiiang™ automatic cleanroom door systems feature brushless DC motors with 500,000 cycle MTBF and leakage rates of ≤0.8 L/s·m² @ 50 Pa.
Modular Cleanroom Sliding Doors
Hermetic/Air-Tight Doors
Critical for sterile applications and isolator interfaces. Inflatable silicone seals achieving ≤0.1 L/s·m² @ 100 Pa. Typical thickness: 60mm with stainless steel 316L construction. Applications: ISO 5-6 areas requiring maximum contamination control. A proper hermetic cleanroom door maintains pressure differentials even during frequent operations.
Pass-Through / Transfer Windows
Alcove and pass-box configurations with mechanical or electronic interlocks. Standard sizes: 400×400mm to 600×800mm. UV interlock options available for decontamination cycles. Deiiang™ pass-through window cleanroom systems feature seamless stainless steel construction and cascade interlock sequences.
Observation/Inspection Windows
Double-paned tempered glass (8+8mm) with anti-fog coating. Maximum size: 1200×1800mm without structural reinforcement. Flush mounting with minimal 3mm reveal for cleanability. Light transmission: ≥92% for optimal visibility. These specialized cleanroom window types provide critical visibility while maintaining environmental integrity.
Modular Cleanroom windows
Key Specification Parameters
Engineering checklist for specifying modular cleanroom doors and modular cleanroom windows must include material compatibility, performance metrics, and integration requirements. These parameters form the foundation of effective cleanroom doors specifications.
Comprehensive cleanroom doors specifications ensure that all components work together to maintain the required cleanliness levels while supporting operational efficiency.
Material Selection Guide
Stainless Steel 304: General applications, Ra ≤0.8 μm
Stainless Steel 316L: Chemical resistance, pharmaceutical
Powder-Coated Steel: Cost-effective, non-critical areas
Tempered Glass: Visibility areas, safety requirement
Performance Metrics
Air Leakage: ≤0.5 L/s·m² @ 50 Pa
Cycle Life: 500,000 operations minimum
Surface Finish: Ra ≤0.8 μm for cleanability
Thermal Insulation: U-value 1.1-1.8 W/m²K
Airtightness Calculations
Leakage rate calculation formula: Q = (V × ΔP) / (t × A) where:
Q = Leakage rate (L/s·m²)
V = Volume (m³)
ΔP = Pressure difference (Pa)
t = Time (s)
A = Door area (m²)
Example Calculation: For a 2.1m² door maintaining 25 Pa pressure differential with 0.5 m³ volume loss over 60 seconds:
Q = (0.5 × 25) / (60 × 2.1) = 0.099 L/s·m² – This meets ISO 5 requirements.
Performance & Test Criteria
Validation of modular cleanroom doors and modular cleanroom windows requires rigorous testing protocols documented in IQ/OQ packages. These criteria ensure reliable performance in critical environments.
Proper testing of both modular cleanroom doors and modular cleanroom windows is essential for maintaining ISO 14644 compliance and ensuring long-term operational reliability in controlled environments.
| Test Type | Standard | Acceptance Criteria | Frequency |
|---|---|---|---|
| Air Leakage | EN 12207 | ≤0.5 L/s·m² @ 50 Pa | Quarterly |
| Cycle Testing | ISO 15821 | 100,000 cycles | Annually |
| Cleanability | USP <797> | ≤1 CFU/25 cm² | Monthly |
Sizing, Clearances & Layout Considerations
Proper dimensional planning ensures efficient operation of modular cleanroom doors and optimal placement of modular cleanroom windows. These considerations impact workflow efficiency and contamination control.
The strategic placement of modular cleanroom doors and modular cleanroom windows directly influences personnel flow, material transfer efficiency, and overall cleanroom performance.
Standard Dimension Guide
Personnel Doors:
900×2100mm
Clear opening: 800×2000mm
Equipment Doors:
1200×2400mm
Clear opening: 1100×2300mm
Pass-through Windows:
500×500mm to 800×800mm
Material transfer only
Clearance Calculation Example: For a sliding door system, required wall space = Door width + (2 × frame thickness) + operational tolerance. For a 900mm door: 900 + (2 × 50) + 25 = 1025mm minimum.
Integration with Control & Interlock Systems
Modern modular cleanroom doors require sophisticated control systems to maintain contamination control protocols. Proper integration ensures seamless operation and compliance with regulatory requirements.
Advanced control systems for modular cleanroom doors and modular cleanroom windows provide the intelligence needed to maintain cleanroom integrity while optimizing operational efficiency.
Interlock Sequence Timing: Cascade interlock systems typically use 5-15 second purge cycles. Calculation: Required purge time = (Room volume × Air changes) / HVAC capacity. Example: 50m³ room with 20 ACH and 1000 m³/hr HVAC = (50 × 20) / (1000/3600) = 3.6 seconds minimum purge time.

FAQ
Are sliding doors suitable for ISO 7?
Yes, properly sealed sliding doors with appropriate gasket systems can maintain ISO 7 classification when installed correctly with proper air pressure differentials (≥15 Pa). Deiiang™ sliding doors achieve leakage rates of ≤0.8 L/s·m² @ 50 Pa, meeting ISO 14644 requirements for Class 7 environments.
How thick should a hermetic door be?
Hermetic doors typically range from 40-80mm thickness, with pharmaceutical applications requiring 60-80mm for adequate insulation and structural integrity. Critical applications may specify 80-100mm for enhanced performance. Deiiang™ hermetic cleanroom door systems feature 60mm thick panels with continuous welds.
What seal type is best for chemical cleaning?
EPDM or silicone gaskets provide excellent chemical resistance against common disinfectants like hydrogen peroxide and isopropyl alcohol. Silicone offers better temperature resistance (-60°C to +230°C) while EPDM provides superior compression set resistance. Deiiang™ recommends silicone for most pharmaceutical applications.
What is the typical lifecycle of cleanroom door seals?
Silicone gaskets: 100,000 cycles, EPDM: 200,000 cycles, inflatable seals: 50,000 cycles. Actual life depends on compression force, chemical exposure, and maintenance frequency. Deiiang™ provides seal replacement kits and recommends preventive maintenance every 2 years.
