Pantai Hospital Penang installed SPL Hermetically Sealed Sliding Door System. utilizes Hermetically Sealed Sliding Door Systems primarily in its Operating Theatres (OT), Intensive Care Units (ICU), and isolation rooms. These systems are critical for maintaining sterile environments and precise air pressure control.
Below are the technical details and functional features typical of the systems installed in such high-standard clinical settings.
The "Hermetic" seal is achieved through a unique patented track system.
The 45° Drop-and-Slide: Unlike standard sliding doors, as the door nears the closed position, the track allows the door to move downward and inward simultaneously at a 45-degree angle.
Compression Seal: This movement forces the door blade against the wall frame and the floor, compressing the high-grade EPDM (ethylene propylene diene monomer) gaskets to create an airtight seal.
Pressure Maintenance: This is vital for Pantai's "Positive Pressure" rooms, ensuring that sterile air pumped into the OT does not leak out, thus preventing contaminated air from corridors from entering.
The doors are engineered to withstand heavy clinical use while remaining easy to sanitize:
Door Blade: Typically 60mm thick with a high-density polyurethane (PU) core for thermal and acoustic insulation.
Acoustic Rating: Most systems offer sound reduction up to 28dB – 32dB, ensuring a quiet environment for surgeons and patients.
To minimize cross-contamination, the system is designed for "hands-free" operation:
Activation: Use of foot sensors, "kick" switches, or infrared touchless hand sensors.
Safety Sensors: Integrated photo-cells or infrared curtains detect obstructions in the doorway, preventing the door from closing on staff or stretchers.
Manual Override: A heavy-duty stainless steel lever handle is usually present to allow effortless manual operation in the event of a power failure.
Microprocessor Control: An intelligent controller manages the opening/closing speed and braking distance to ensure smooth, quiet motion.
| Feature | Clinical Benefit |
| Airtightness | Prevents the spread of airborne pathogens and maintains sterile "Clean Room" status. |
| Space Saving | Sliding doors don't require the "swing" radius of traditional doors, allowing more usable space for medical equipment. |
| Hygiene | Seamless construction prevents the growth of bacteria and mold in gaps or joints. |
| Durability | Built for high-frequency use (hundreds of cycles per day) without losing the integrity of the seal. |
