In the realm of biosafety and controlled environments, the integrity of doors is crucial for preventing the entry or exit of contaminants. QUALIA’s Mechanical Seal APR Doors are designed to meet these stringent requirements, offering a specialized containment solution for biosafety areas.
Key Features of QUALIA’s Mechanical Seal APR Doors
Material Excellence
These doors are constructed from premium 304 stainless steel, with a thickness of 3 mm, ensuring durability and resilience. The full welding on both door frames and leaves, along with corner arc welding, provides a smooth and professional finish.
Advanced Seal Material
The high-density EPDM (Ethylene Propylene Diene Monomer) sealing strips offer optimal resistance to corrosion, oxidation, and chemical agents. These strips have a service life of at least 5 years, significantly outlasting competitors' seals which last only 1-3 years.
Efficient Opening Mechanism
The doors can be operated using a disc-style turnwheel or a push rod, with an opening angle of 45°. This internal mechanical structure is easy to use and requires minimal maintenance.
Aesthetic and Functional Design
The fully concealed multipoint pressing mechanism ensures even pressure distribution and exceptional sealing. This design also maintains a clean and easy-to-maintain appearance.
Superior Observation Windows
The doors feature at least 12 mm thick tempered glass or a 32 mm double-layered circle variant, providing both safety and ease of cleaning.
Seal Integrity and Performance
| Feature | QUALIA’s Doors | Competitors’ Doors |
|---|---|---|
| Seal Integrity | ±2000Pa decay <0.5% Vol/h over 20 minutes | 100Pa less than ≤0.5% Vol/h |
| Compression Mechanism | Multi-point concealed compression | Single-point or exposed multi-point compression |
| Door Operating Mechanism | Disc-style turnwheel or push rod, 45° opening angle | >65° |
| Mechanical Seal Strip | EPDM (Ethylene Propylene Diene Monomer), 6±5° shore A | Silicone rubber |
| Service Life of Seal Strip | ≥5 years | ≤1-3 years |
| Corners of Seal Strip | R95 | R100 |
| View Window | 12mm thick tempered glass, round disc style | Square-shaped |
High Security and Biosafety Compliance
These doors are designed for use in biosafety laboratories, pharmaceutical facilities, medical centers, and other environments requiring stringent control, such as P3 and P4 level labs. The mechanical sealing mechanism maximizes the seal between the door leaf and frame, preventing contaminants from entering or leaving the controlled zone. The system can be operated manually or automatically, exerting pressure against the frame when closed to create a highly secure seal.
Operational Benefits
- Minimal Maintenance: The internal mechanical structure is designed for ease of use and minimal maintenance.
- Integrated Features: The doors come with interlock and alarm features integrated, ensuring that the environment remains controlled and secure.
- Emergency Preparedness: While the pneumatic seal doors have additional emergency deflation valves, the mechanical seal doors ensure consistent performance under normal operating conditions.
Conclusion
QUALIA’s Mechanical Seal APR Doors are a testament to innovative engineering and a commitment to biosafety. With their advanced materials, efficient mechanisms, and superior seal integrity, these doors are ideal for any environment requiring strict control over contaminants. Whether in a laboratory, pharmaceutical facility, or medical center, these doors ensure optimal biological and chemical isolation, making them an indispensable asset in maintaining a secure and controlled environment.
