Electric sliding door motor kit
Designed for long service life and stable performance, it features intelligent obstacle detection, adjustable opening/closing speed, soft start & stop, and manual release for emergency use. With IP45 weatherproof rating and robust construction, it works reliably in diverse environments. Ideal for shops, offices, warehouses, homes, and high‑frequency entry points.
Powerful and Stable Drive System
The kit uses a high torque 24V DC brushless motor as its core power component, delivering strong and consistent output to move door leaves smoothly even under heavy load. It supports a maximum leaf weight of up to 300kg for single leaf and double leaf configurations, making it suitable for standard interior doors, shop front glass doors and office partition doors. The motor adopts a gearless direct drive structure that reduces mechanical friction, lowers energy consumption and extends service life. Precision helical gear transmission ensures stable movement with low vibration, while the pure copper coil provides high efficiency and low heat generation for continuous daily use. The system supports adjustable operating speed, with opening speed ranging from 0.4m/s to 0.7m/s and closing speed from 0.3m/s to 0.6m/s, allowing fine tuning for different scenarios. Soft start and soft stop functions eliminate sudden jolts, improve user comfort and reduce stress on door frames and hardware.
Intelligent Microprocessor Control
At the heart of the kit is a self learning microprocessor controller that automatically detects door weight, friction resistance and travel distance to optimize operating parameters without manual adjustment. The controller stores multiple working modes, including full automatic, half open, hold open, exit only and night lock, to match different usage requirements. Users can adjust delay time for closing, sensitivity of obstacle detection and force limits via the control panel or wireless remote. The system features real time status monitoring and fault self diagnosis, with visual indicators for normal operation, obstruction, power loss and other conditions. It supports multi device linkage, including access control systems, security sensors, fire alarm interfaces and lighting controls, to create a unified building entrance management solution. Low power consumption in standby mode reduces energy waste, supporting eco friendly and cost efficient operation.
Comprehensive Safety Protection Functions
Safety is a core design focus, with multiple layers of protection to prevent injury and equipment damage. Obstacle detection works during both opening and closing: if an object or person is detected, the door immediately stops or reverses direction to avoid impact. The kit includes infrared photocell sensors and mechanical safety edges as standard, providing dual zone detection for enhanced reliability. Motor overcurrent and overheating protection automatically cuts power under abnormal load to prevent burnout. In the event of power failure, a manual release mechanism allows the door to be operated by hand for emergency exit or access. The system complies with international safety standards for automatic doors, including EN 16005, ensuring safe use in busy public areas such as shopping malls, hospitals, hotels and office buildings. The closing force is strictly limited to avoid pinching risks, making the kit suitable for environments frequented by children, elderly people and individuals with mobility needs.
Durable Construction and Weather Adaptability
The motor and controller housings are made of high strength die cast aluminum alloy, which is lightweight, rust resistant and able to withstand long term mechanical stress. The internal components are treated for dust and water resistance, reaching IP44 protection level to operate reliably in damp or dusty environments. The kit supports an operating temperature range from -20°C to +55°C, adapting to different climate conditions. Wear resistant suspension rollers and anti derailment design keep the door leaf stable and aligned during movement, reducing noise and maintenance needs. High quality cables and connectors ensure stable electrical connection and resist aging. All mechanical moving parts use lubricated components designed for long service intervals, lowering maintenance cost and downtime. The robust structure allows intensive use in high traffic locations, with a tested service life of more than one million opening and closing cycles.

FAQ
1. What is a cold storage sliding door electric control system?
It is an automation kit designed to convert manual cold storage sliding doors into automatic ones. It typically consists of a motor, a control box (PLC/Inverter), a drive track or belt, and various activation sensors.
2. Can your system be retrofitted onto existing manual doors?
Yes, our systems are designed to be universal. They can be installed on most existing manual sliding doors, provided the door track and wheels are in good condition.
3. What types of cold storage doors is this system compatible with?
It is compatible with light, medium, and heavy-duty horizontal sliding doors used in chillers, freezers, blast freezers, and controlled atmosphere rooms.
4. What is the difference between a standard motor and an inverter (VFD) system?
A standard motor operates at a fixed speed. An inverter (VFD) system allows for variable speeds (soft start and soft stop), which protects the door mechanics and allows for faster opening times to save energy.
5. Do you offer systems for stainless steel or food-grade environments?
Yes, we offer motor kits with IP65-rated stainless steel control boxes and corrosion-resistant components suitable for food processing and pharmaceutical applications.
6. What is the input voltage requirement?
Our standard units are single-phase 220V/50Hz. However, we can customize motors for 110V/60Hz or 3-phase 380V depending on industrial requirements.
7. What is the maximum door weight your motor can handle?
We have different models ranging from light-duty (up to 200kg) to heavy-industrial (up to 800kg or 1000kg).
8. What is the operating temperature range?
Standard models operate between -20°C to +45°C. For blast freezers, we offer a low-temperature series capable of operating down to -45°C with integrated heating elements.
9. What is the opening and closing speed?
Speeds typically range from 20cm/s to 50cm/s. Systems equipped with a frequency inverter can be adjusted to run faster (up to 60cm/s) to minimize air loss.
10. Does the motor use a belt drive or a rack and pinion?
We offer both. Rack and pinion is better for heavy, industrial doors, while synchronous belt drives are quieter and smoother for smaller to medium-sized doors.
11. What is the IP rating of the control box?
Our standard control boxes are rated IP54 or IP65, protecting against dust ingress and low-pressure water jets (wash-down safe).
12. Does the system support "Drop Down" (hermetic) rail systems?
Yes, our motors have a specialized "closing force" setting that pushes the door firmly at the end of the cycle to engage drop-down rails and ensure a hermetic seal.
13. Can I install the motor on either the left or right side?
Yes, the system is reversible. The opening direction (left or right) can be easily set via the DIP switches or the digital controller menu.
14. How much space is required above the door for installation?
Generally, you need at least 150mm to 200mm of clearance above the door track to mount the motor and drive mechanism.
15. Do you provide wiring diagrams?
Yes, every unit comes with a detailed English installation manual and wiring diagram. We also offer video support for technicians.
16. Is the limit switch mechanical or digital?
We use encoder-based digital limit setting for our advanced models (no physical limit switches to adjust). Economy models may use magnetic or mechanical limit switches.
17. What happens if the door hits an obstacle while closing?
The system features an automatic reverse function. If the motor detects resistance (like a forklift or person), it will stop and reverse to the open position immediately.
18. Does the system function during a power outage?
In the event of power failure, the electric clutch disengages (or can be manually disengaged), allowing the door to be opened and closed manually with very little effort.
19. Is there an "emergency stop" feature?
Yes, the control box usually includes a large Red Emergency Stop button. Additionally, safety edges can be installed on the door leaf.
20. Can I set an automatic closing timer?
Yes, you can program the door to automatically close after a set time (e.g., 10 seconds, 30 seconds) to prevent employees from leaving the freezer open accidentally.
21. What is the "Half-Open" or "Pedestrian" mode?
This feature allows the door to open only partially for personnel entry, minimizing cold air loss compared to fully opening for a forklift.
22. What types of switches can trigger the door?
The system supports push buttons, pull cords (ceiling switches), remote controls, radar sensors, magnetic induction loops, and facial recognition terminals.
23. Can I use a remote control?
Yes, most of our controllers have a built-in receiver module that supports wireless remote controls up to a range of 50-100 meters.
24. Can this system interface with an Air Curtain?
Yes, the control box has a relay output specifically for air curtains. It turns the air curtain on when the door opens and off when it closes.
25. Does it support Interlocking (Airlock) function?
Yes, for facilities with anterooms, two doors can be interlocked so that Door B cannot open until Door A is fully closed.
26. Do I need a safety edge sensor?
While the motor has built-in resistance detection, we highly recommend installing a rubber safety edge (air wave or electric) for maximum safety compliance.
27. How do I troubleshoot errors?
The advanced control box features an LED display that shows error codes (e.g., E1 for motor error, E2 for sensor blockage), making troubleshooting easy.
28. Does the motor require lubrication?
Most of our motors use sealed bearings and are maintenance-free. However, the drive chain or rack should be greased periodically, especially in humid environments.
29. Why is my door moving slowly?
This could be due to ice build-up on the track, worn-out roller wheels, or the speed setting on the inverter needs adjustment.
30. What happens if the door freezes shut?
Our motors have a high starting torque to break minor frost seals. For severe icing, we recommend installing frame heating cables to prevent the door from sticking.
31. What is the warranty period?
We typically offer a 12-month to 24-month warranty on the motor and control board, depending on the model purchased.
32. Do you sell spare parts separately?
Yes, we stock replacement control boards, remotes, belts, and motors for quick shipment.
33. Can you customize the logo on the control box?
Yes, we offer OEM services and can print your company logo on the control panel for bulk orders.
34. What is the lead time for 50 sets?
Standard production time is usually 10-15 days for orders under 100 sets.
35. How is the product packaged for export?
The kits are packed in reinforced carton boxes with foam padding. For larger shipments, we use wooden pallets to prevent damage during sea freight.
