1、 Advantages of Material Characteristics
304 stainless steel
Stainless steel made of 304 material has excellent corrosion resistance. In many industrial environments, such as around chemical workshops or areas with high humidity and a small amount of acidic gases, it can prevent the corrosion of the control box casing, thereby extending the service life of the control box.
Its excellent mechanical performance ensures that the control box is not easily damaged when subjected to certain external impacts or vibrations. For example, in places where factory equipment frequently starts and stops generating vibrations, 304 material can maintain the integrity of the structure.
2、 The significance of double layered door design
safety protection  
The outer door provides a preliminary protective barrier to prevent non professionals from accidentally touching the internal circuit components. The inner gate further isolates critical circuit components from the outside world. When conducting internal maintenance or repairs, closing the inner gate can avoid the danger of accidentally touching other circuits and causing short circuits during operation.
The space between the double layered doors can be filled with insulation material to enhance the overall insulation effect. This is important for electric heat tracing systems, as excessively high external temperatures may affect the performance and lifespan of electronic components inside the control box.
3、 Characteristics of 12 circuits
Functional diversity
12 circuits can meet the electrical heating needs of complex locations. For example, in a large warehousing and logistics center, there are multiple pipelines and equipment in different areas that require electric heat tracing and insulation, and each circuit can correspond to a specific area separately.
More advantageous in power management. It is possible to accurately allocate appropriate power to each circuit based on factors such as the size, material, and required temperature of each heat tracing object, improving energy utilization efficiency and ensuring that each area can achieve heat tracing effect.
Control flexibility
Multiple control methods can be combined. For example, for some circuits that require high temperature accuracy, PID control algorithm combined with temperature sensors can be used for accurate temperature control; For some relatively simple circuits, basic fixed value control or simple timing control can be used. The control parameters of each circuit can be independently set without interfering with each other.
4、 Key points for installation and maintenance
Installation points
The installation location should consider good ventilation to facilitate heat dissipation of the control box. If installed in a narrow and enclosed space, it may cause excessive temperature inside the control box, affecting the normal operation of electronic components.
To ensure the levelness of the installation position and avoid problems such as loose internal component connections or local stress concentration caused by tilting.
Electrical connections must be strictly carried out in accordance with specifications to ensure the correct and error free wiring of each circuit, good grounding, and prevent leakage accidents.
Maintenance points
Regularly inspect the 304 material casing for signs of damage or corrosion, and repair or replace it promptly if found.
Regularly inspect the internal circuits, including checking whether the wires of each circuit are damaged, whether the joints are loose, and whether the fuses are working properly.
When cleaning the control box, the power should be cut off first, and dry and soft tools should be used for cleaning to avoid scratching internal components or causing short circuits.
