1、 Characteristics of 304 material
Corrosion resistance
In various industrial environments, 304 stainless steel can resist corrosion. Like in chemical workshops with acidic and alkaline gases, or near coastal buildings with high humidity and salt content, it can prevent the control box casing from being corroded and protect internal components.
Even if exposed to some chemical cleaning agents or oil stains for a long time, 304 material is not easily corroded and damaged.
Mechanical performance
It has high strength and can withstand certain external impacts during transportation and installation. For example, when accidentally dropped or collided with other equipment during transportation at the construction site, it is not easy to deform and damage.
Good toughness, able to maintain structural stability and reduce the risk of internal component loosening in environments that are subjected to long-term vibration (such as near large operating equipment).
2、 The significance of double layered door design
safety protection  
The outer door can prevent non professionals from opening and seeing the internal circuit at will, reducing the possibility of misoperation. The inner gate further isolates the core circuit components, and during maintenance or adjustment, the inner gate should be closed to avoid accidentally touching other circuits and causing short circuits and other problems.
The space between the double layered doors can be filled with insulation materials to enhance the insulation effect. This is important for electric heat tracing control boxes because they generate heat during operation. Good insulation can reduce heat loss to the outside world and prevent external heat from affecting the performance of internal components.
Upgrade of protection level
This design helps to improve the overall protection level of the control box and meet the requirements for use in some special places, such as humid, dusty, or slightly corrosive gas environments.
3、 Characteristics of 16 circuits
Application flexibility
16 circuits can meet the electrical heating needs of large-scale or complex layout locations. For example, in large factories where numerous pipelines and equipment require electric heat tracing with different power and temperature control, each circuit can correspond to a specific area separately.
It has more advantages in power allocation, as it can accurately allocate power based on the specific conditions of the object being heat traced (such as length, pipe diameter, required temperature, etc.), improve energy utilization efficiency, and ensure that each area achieves appropriate heat tracing effects.
Diversity of Control Functions
Each circuit can be controlled independently. For the heat tracing circuit of key equipment, high-precision intelligent temperature control can be used, combined with temperature sensor feedback data to accurately adjust power; For auxiliary circuits, simple timing or manual control methods can be used.
4、 Installation and maintenance precautions
Installation aspect
The installation location should be dry, well ventilated, and away from water sources and flammable and explosive materials. If outdoors, measures such as rain, sun, and wind protection should be considered.
The installation should be firm, grounded according to regulations, and ensure safe use.
Reasonable wiring ensures that the 16 circuits are clear and tidy, facilitating future maintenance and repair.
Maintenance aspect
Regularly inspect the 304 material casing for any damage or corrosion and promptly address any issues.
Regularly inspect the internal circuit, including whether the wire connections are secure, whether the fuses are working properly, and whether the relays and other components are working properly.
When cleaning the control box, first cut off the power and clean it with a dry and soft tool to avoid scratching the components or causing short circuits.
