Construction of a Cleanroom for a Power Distribution Box in Nepal

A cleanroom for a power distribution box in Nepal can be efficiently constructed using modular cleanroom panels, proper electrical planning, and ISO-compliant design to ensure contamination control and operational safety.

Cleanroom Design Considerations

When constructing a cleanroom for a power distribution box, the primary goal is to minimize airborne particles, dust, and microbial contamination while ensuring safe and reliable electrical operation. Modular cleanrooms are preferred due to their cost-effectiveness, faster installation, and flexibility for future expansion . The cleanroom should be designed according to the ISO classification suitable for electrical equipment, typically ISO Class 7 or 8, depending on sensitivity . Key design elements include:

• Wall and Ceiling Panels: Use modular sandwich panels with aluminum honeycomb cores or FRP/CPVC panels that are non-shedding, flame retardant, and easy to clean .
• Doors and Windows: Install airtight doors with proper seals and optional flush glazing to maintain pressure differentials and prevent contamination .
• Flooring: Anti-static, chemical-resistant flooring is recommended to prevent static discharge and contamination.

Electrical and Power Considerations

Electrical planning is critical for a cleanroom housing a power distribution box:

• Dedicated Electrical Panels: Install a dedicated panel to handle the cleanroom's load, including lighting, HVAC, and any monitoring equipment .
• HVAC and Filtration: HEPA-filtered fan units and proper HVAC systems are essential to maintain air cleanliness and temperature control. HVAC is typically the largest power consumer, often requiring 230V or 480V supply .
• Lighting: Use LED cleanroom lights with universal voltage to reduce heat and energy consumption .
• Power Distribution Modules (PDMs): These simplify connections to fan/filter units and control panels, ensuring safe and organized power distribution .

Construction and Installation

• Modular Assembly: Modular cleanrooms allow for quick assembly and disassembly, which is ideal for retrofitting existing spaces or future upgrades .
• Process Utilities: Ensure proper exhaust, pressurization, and airflow systems to prevent cross-contamination and maintain operational efficiency .
• Monitoring and Control: Include control panels for monitoring temperature, humidity, and particle counts to maintain compliance with ISO standards .
