Corrosion-Resistant Wall-Mount Enclosure

Modular splicing: The patented snap-on structure supports rapid expansion, and multiple boxes can be combined within 30 minutes to meet the deployment requirements of edge computing nodes in data centers.

Invisible heat dissipation system: Utilizing the thermal conductivity of stainless steel and the micro-groove design on the inner wall, 200W heat dissipation can be achieved without an external fan, which is suitable for high-temperature environments (such as smelting workshops).

Humanized operation: Removable hinged door, internal DIN rail installation and optional tempered glass observation window support rapid maintenance and real-time monitoring.

Installation and maintenance points

Installation steps:
Use M6 expansion bolts (torque 15N・m) for concrete walls and self-tapping screws + waterproof gaskets for metal walls to ensure horizontal deviation <2mm.
Introduce cables from the bottom gland and fill the gaps with sealing putty to maintain IP rating.

Maintenance list:
Check the compression of the sealing ring (≥2mm) quarterly and remove oxidation spots with 3M stainless steel cleaner annually.
Replace the EPDM rubber strip every three years and heat it to 50°C to ensure sealing.

Strict certification and environmental protection

 

It has passed international certifications such as UL, CE, and ISO 14001. The raw materials can be traced back to RMI-compliant mines. The production process uses cyanide-free electroplating technology, and the nickel content of wastewater is less than 0.1mg/L (better than GB 21900-2008 standard).
The recycling rate is as high as 90%, far exceeding plastics (30%) and aluminum alloys (70%), and meets the circular economy requirements of the EU WEEE Directive.

Be used in a wide range of industries.

How to ensure that the cable entry does not damage the corrosion resistance and waterproof performance of the shell during installation? ​

The key lies in the sealing treatment of the cable penetration: ​

Use a dedicated waterproof connector: The standard stainless steel gland must match the cable diameter, and the internal rubber seal must completely wrap the cable sheath. After tightening, the waterproof level can reach IP66. ​

Multi-cable scenario: If multiple cables are passed through, a multi-hole sealing plate (with elastic silicone pad) must be used. The single-hole single-cable design avoids water seepage in the gap; the redundant holes are sealed with waterproof plugs. ​

Direct hole opening is prohibited: non-standard holes must be pre-installed by the manufacturer to avoid on-site cutting that damages the surface passivation layer (stainless steel) or resin matrix (FRP), resulting in local corrosion. ​

Grounding treatment: The shielding layer of the metal shell cable must be reliably connected to the box through the grounding bolt to prevent electrochemical corrosion (especially when different metals are in contact).
