Insulated PVC High Speed Door Cold Storage 1-Year Warranty For Freezer Storage

The High Speed Cold Room Door is a professional Cold Storage High Speed Door specifically engineered for freezer rooms and low-temperature cold storage environments. Designed to operate reliably under freezing conditions, this Freezer High Speed Door combines advanced servo control, superior thermal insulation, and a dual-side track heating system to ensure stable performance, fast operation, and minimal cold air loss. With high-speed opening and closing, excellent sealing performance, and enhanced safety protection, the door plays a critical role in maintaining temperature stability, improving cold chain efficiency, and reducing energy consumption in modern cold storage facilities.

Product Specifications

Control System (Servo System)

1. Equipped with a dedicated servo control system with a DSP chip at its core. The system determines the door opening height by combining incremental encoder signals from the motor shaft with mechanical home-position switch signals.

2. LED display for real-time fault code indication and diagnostics.

3. Direction protection: If the motor drive wiring is connected incorrectly, the controller immediately reports an error and prevents door operation.

4. Full closed-loop control: Torque loop, position loop, and speed loop for high-precision operation.

5. Vector braking function: The motor can stop precisely at the preset position without the need for an electromagnetic brake, ensuring accurate stopping at limit positions with no deviation.

Drive Motor

1. The drive system adopts a servo motor system, including encoder, braking system, gearbox, and emergency manual opening mechanism.

2. Constant torque output of the servo motor ensures optimal performance of safety devices (such as infrared sensors) with fast rebound response.

Safety Features

1. Infrared Safety Protection:
Photoelectric sensors are installed on both sides of the door frame. When an object is detected under the door, the door remains open. If an object passes underneath during closing, the door opens to the fully open position and descends again after a delay once the area is clear.

2. Bottom Safety Edge:
If an object is located in the infrared blind zone during closing, the door immediately rebounds to the fully open position upon contact, effectively protecting people and objects and preventing accidents. (Standard configuration)
