OEM Dustproof Danfoss VFD Siemens PLC Control Cabinet HMI LV Switchgear
Product Describe:
• Protection Level and Structural Design: Their outdoor enclosures can cope with dusty, high-temperature and high-vibration environments. The protective vents can balance the internal pressure, block dust and dirt, and prevent wear of rubber seals. For example, in the food and beverage industry, some Danfoss VLT® series drives reach IP66/UL type 4X protection level, which can resist daily high-pressure washing and dust intrusion, meeting strict hygiene and dust-proof requirements.
• Air Duct and Heat Dissipation Design: The air duct is carefully designed to ensure smooth air exhaust and avoid dust accumulation caused by eddy currents in the cabinet. At the same time, a protective top cover is installed at the top air outlet to prevent debris from falling directly in, and a protective net is installed at the side air outlet to block flocculent debris, which greatly reduces dust entry while ensuring heat dissipation efficiency.
• Sealing Treatment: The front and rear doors of the control cabinet and other joints are sealed with gaskets or sealants, which effectively prevent dust from entering through the gaps and ensure that the internal electronic components are isolated from dust.

| Standard Sizes |
- Cabinet dimensions: The common height range is 1200mm to 2200mm, the width range is 600mm to 1000mm, and the depth range is 400mm to 800mm (for example, 1800mm × 800mm × 600mm is commonly used for medium-power units). - Installation space: Designed to fit standard electrical enclosures, with panel mounting holes conforming to industry specifications for easy on-site installation. |
| Custom Sizes |
- Adjust the height/width/depth according to the capacity of the variable frequency drive (larger units are required for high-power motors) or space constraints (for example, compact cabinets of 600mm × 400mm × 300mm can be used for small pumps in narrow areas). - Modify the size of internal compartments to accommodate additional components (sensors, communication modules, etc.) or meet specific wiring layout requirements. - Can be customized into wall-mounted (thinner depth) or floor-standing (sturdier frame) installation forms as needed. |
IP Grade:
IP30/IP40/IP54 / IP55 /IP66
Suggestion:
1. For Danfoss: Upgrade to IP66/UL type 4X for extreme dust; add custom air filters for specific debris (e.g., food particles).
2. For Siemens: Opt for IP54+ enclosures with reinforced seals for mining/dusty areas; integrate heat-resistant materials for high-temperature environments.
3. Common tweaks: Customize vent sizes for airflow-demand balance; add sensor-linked auto-cleaning filters for low-maintenance setups.
