Dual-Motor Automatic Hermetic Sliding Door

As a professional manufacturer and supplier, OWNIC has upgraded its standard hermetic doors to develop and produce the Dual-Motor Automatic Hermetic Sliding Door. This innovative product utilizes two independent motor drive systems operating in tandem, ensuring enhanced stability and safety, making it ideally suited for high-standard medical environments.

Application:

OR room,newborn room,entrance,CT room, and other areas in high purification level

Product Features:

1. Equipped with original German-made DC motors, ensuring long service life and high efficiency.
2. Air tightness complies with the Chinese national standard (GB/T 7106-2019), achieving the 3.highest Level 8, and meets the EU standard (EN-12207), achieving the highest Class 4.
4. Utilizes PID closed-loop control technology and FOC space vector closed-loop control. Dual-motor synchronous drive with intelligent interactive communication enables automatic torque output balancing.

Technical Data:

How Does the Dual-Drive System Work?

Traditional single-motor sliding door systems rely on a single motor to handle all operations—opening, closing, and hermetic sealing. Since the power required for the airtight compression action is shared with the sliding mechanism, performance fluctuations can easily occur under heavy loads or during high-frequency usage.

Building upon this foundation, we have upgraded our system to feature dual motors. These two independent systems operate in tandem under a unified control scheme: Motor 1 governs the lateral movement of the door—handling the opening and closing functions—while Motor 2 is dedicated to controlling the vertical lowering and compression of the door body.

By choosing our Dual-Motor Automatic Hermetic Sliding Door, you benefit from:

✔ More precise sealing actions

✔ More stable operational logic

✔ A lower risk of malfunctions

FAQ

Q: Why is a dual-motor drive recommended for large or heavy-duty protective doors?

A: For heavy doors—particularly those fitted with lead shielding (for radiation protection) or large panes of insulated glass—a single motor operating under a constant heavy load is prone to overheating and belt wear over time. A dual-motor system provides double the torque, ensuring smoother and more fluid opening and closing operations.

More importantly, it offers a critical safety redundancy feature: should one motor require maintenance, the other can continue to sustain basic functionality, ensuring that medical passageways remain operational during critical moments.

Q: How effective is the noise reduction on the Dual-Motor Automatic Hermetic Sliding Door? Will it disrupt the operating room environment?

A: Hospitals have extremely stringent requirements regarding noise control. OWNIC employs proprietary low-noise brushless DC motors and a silent guide rail design, keeping operational noise levels below 45dB.

Whether late at night or during high-precision surgical procedures, the opening and closing of the door will not interfere with the work of medical staff or the rest of patients.

Q: Can the automatic hermetic medical door still be opened in the event of a power outage?

A: Yes, it can; safety is always our top priority.

Backup Power: Our system can be configured with a UPS backup power supply, enabling the door to perform multiple automatic opening and closing cycles even after a power failure.

Manual Opening: The door's structural design is ergonomically optimized; even in a complete power outage, medical staff can easily push the door open using the manual handles, ensuring that emergency escape routes remain unobstructed.
