Product Showcase

This 25kVA compact silent genset features streamlined silent canopy. The shell adopts thickened carbon steel sheet, formed by bending and continuous welding. The exterior surface uses high-adhesion electrostatic anti-corrosion coating, resisting scratches and outdoor fading. Side maintenance door is reasonably laid out for easy routine inspection and component replacement. Optimized compact air duct design ensures stable heat dissipation while cutting airflow noise. Reinforced base fitted with integrated lifting holes for safe integral hoisting. Inner cavity is fully lined with high-density flame-retardant sound-absorbing material and acoustic baffles, minimizing sound leakage from gaps. The sealing strips around door frames reduce vibration noise during continuous operation.

Key Specifications

Noise Reduction Technology: Crafted for Silence

WOPUSAI compact silent canopy adopts tailored noise reduction solution, specially calibrated for 25kVA low-load operation, achieving quiet running without sacrificing heat dissipation performance.

1. Compact Optimized Labyrinth Air Duct

Streamlined labyrinth air channel matches the compact cabinet size. Multi-stage bending design weakens airflow noise step by step, and blocks dust and dew entering the cabin. Built-in silencer cavity absorbs exhaust noise. Continuous sealing gaskets eliminate assembly gaps to prevent sound leakage, stable for long standby cycles.

2. High-density Flame-retardant Sound Absorbing Layers

The canopy inner wall is fully covered with thickened acoustic materials:

• Composite sound absorbing structure absorbs low-frequency vibration and airflow noise
• High-temperature resistant material adapts to continuous outdoor standby
• Firm bonding process prevents peeling and hollowing, maintaining stable mute performance

3. Compact Vibration Isolation Structure

Vibration isolators are installed between unit and base frame, cutting vibration transmission paths. It suppresses cabinet resonance during operation and reduces abnormal rattling noise, improving overall mute performance of the compact enclosure.

4. Rigid Compact Canopy & Base Frame

The whole canopy uses integral welded steel plate with stress relief treatment, rigid and not easy to deform. Anti-corrosion coating delivers good waterproof, dustproof and anti-aging capacity. The reinforced base is equipped with integrated lifting holes, bearing load safely for whole set hoisting.

🎯 Application Scenarios

• Residential Villa Backup: Low-noise emergency power supply for villa and residential areas
• Small Commercial Premises: Shops, studios and small office standby power
