1、 Characteristics of 304 material
Corrosion resistance
304 stainless steel has excellent corrosion resistance in various environments. In industrial environments with slightly corrosive gases such as sulfur dioxide, or in places with high humidity for a long time (such as the electric heating system control box in underground parking lots), it can prevent rusting and corrosion of the box and ensure the safety of internal circuit components.
For situations where there is a possibility of exposure to certain chemicals (such as residual cleaning agents), 304 material can also resist well and avoid corrosion damage.
Mechanical performance
Its strength and toughness enable the control box to withstand certain external impacts during transportation, installation, and daily use. For example, during the transportation process at the construction site or when affected by vibrations generated by nearby equipment operation, deformation and damage are less likely to occur.
2、 Double layered door design advantages
Security guarantee
The outer door plays a preliminary protective role, preventing unrelated personnel from opening and seeing the internal circuit layout, reducing the risk of misoperation. The inner gate further protects the core circuit components. When conducting internal maintenance or adjustment, closing the inner gate can avoid accidental contact with other circuits during operation, causing short circuits and other problems.
The space between the double layered doors can be sealed to enhance the insulation effect. This is important for electric heat tracing control boxes because the electric heat tracing system generates heat during operation. Good insulation can reduce heat loss to the outside world and prevent external heat from entering and affecting temperature sensitive components inside the control box.
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 Circuit 13
Application flexibility
13 circuits can meet the electric heating needs of large-scale or complex layout places. For example, in large chemical enterprises, numerous pipelines, reaction vessels, and other equipment require different electric heating power and temperature control. Each circuit can be individually set for specific equipment or pipeline areas.
It has more advantages in power allocation, as it can accurately allocate the power of each circuit according to the specific conditions of different heat tracing objects (such as length, pipe diameter, required temperature, etc.), improve energy utilization efficiency, and ensure that each area can achieve appropriate heat tracing effect.
Diversity of Control Functions
Each circuit can be controlled independently. For example, for some key equipment's heat tracing circuits, high-precision intelligent temperature control can be used, combined with temperature sensor feedback data, to accurately adjust the output power; For some auxiliary heat tracing circuits, simple timing control or manual control can be used.
4、 Installation and maintenance precautions
Installation aspect
The installation location should be chosen in a dry and well ventilated place, away from water sources and flammable and explosive materials. If installed outdoors, measures such as rain, sun, and wind protection should also be considered.
Ensure that the installation is secure and grounded according to electrical installation standards to ensure safe use.
Reasonably plan the wiring to ensure that each circuit is 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 circuits, including checking whether the wire connections of each circuit are secure, whether the fuses are working properly, and whether the relays are working properly.
When cleaning the control box, the power must be cut off first, and dry and soft tools should be used for cleaning to avoid scratching internal components or causing short circuits.
