12. drying system Noise ≤65dB, dual fan air supply, dual-stage heating system

13. cleaning spray arm

It has top and bottom spray arms, each spray arm has two spray rods, 360° no dead angle. All spray rods can be disassembled manually without tools.

14. PLC controller

The PLC control, the automatic fault detection function, the sound alarm function, the strong anti-interference ability and the high stability.

15. Display content

The system displays temperature, time, current phase, runtime, and alarm information, with real-time calculation and display of A₀values and internal hardware status. It visually identifies active components, facilitating maintenance while providing clear insights into the equipment’s operational process and principles. The interface also includes actual display screen photos.

16. ★ display screen

Display: Features a 7-inch touchscreen with 1024×600 resolution and 24-bit color depth, paired with 256MB DDR3+ RAM and 4GB eMMC storage. Certified to EN61000-6-2:2005 and EN61000-6-4:2007

standards, it complies with RoHS requirements for lightning surge protection (±1kV), group impulse (±2kV), electrostatic discharge (4kV), and air discharge (8kV). The device includes lightning surge protection and ensures power loss response time under 5ms.

17. security guard

Door motor: When the equipment motor is overloaded, the overcurrent protection switch activates, and the motor stops working.

Circulating fan: When the air pressure is too low causing the air heating pipe to dry burn, the system automatically cuts off the heating power and issues an alarm for fan failure.

Circulating pump: If a fault occurs, the system automatically detects and terminates the program.

The amount of enzyme solution and lubricating oil: when the consumables are insufficient, it gives a prompt;

Heater: The system automatically cuts off the heating power when the

water level is low and the heating tube burns out. It adopts a double heating protection design for greater safety and reliability.

The door anti-pinch device: when the door is blocked during closing, it will stop closing and run in the opposite direction;

Overheat protection: Dual temperature detection. If the temperature exceeds the set value, the system automatically cuts off the heating power.

18. ★ programmed

The bidding equipment has ≥10 pre-installed programs and ≥20 custom programs. Users can edit programs and customize program control names as needed.

19. spray system

Removable spray arms for easy cleaning. High-flow circulation pump.

Multi-stage filtration (inlet filter + recirculation filter) to prevent clogging.

20. recording mode

The system features a traceability system for operational process records and alarm logs, with information directly displayed on the touchscreen for real-time monitoring by relevant personnel. It can store complete sterilization records for no fewer than 8,000 sterilization cycles.

21. data read

Read historical data from sterilization processes and directly export sterilization records to a USB drive for permanent storage.

22. Cleaning Effect

The equipment passed the cleaning test with satisfactory results.

23. Disinfection effect

The equipment has been tested for both moist heat and chemical disinfection, with all results meeting the standards. The program can be customized, and the heating temperature should be set within the

range of room temperature to 95°C.

24. identity recognition technology

Users can access the operating system with a password to perform operations.

25. Traceability system:
