Anti-Rust Noise Reduction LNG Generator Set

Kecheng Anti-Rust Noise Reduction LNG Generator Set is manufactured by Shandong Kecheng Electric Power Equipment Co., Ltd., a professional Supplier of natural gas and LNG power generation equipment in China. The unit combines anti-corrosion structure design, low-noise technology, and intelligent control to support industrial, commercial, municipal, and distributed energy applications requiring long-term operational stability.

Structural Design for Corrosion Resistance and Low Noise

Anti-Rust Enclosure Construction

• Outer enclosure uses cold-rolled steel plate with anti-rust coating treatment.
• Surface treatment adopts electrostatic spraying and high-temperature baking paint process to improve corrosion resistance.
• Suitable for coastal regions, humid environments, construction sites, and outdoor installation scenarios.
• IP23 protection grade helps reduce dust and water intrusion during operation.

Noise Reduction Configuration

• Double-layer soundproof enclosure structure.
• Internal sound-absorbing cotton reduces operational noise by approximately 20dB.
• No-load operating noise is ≤85dB at 1 meter.
• Airflow channel design balances ventilation efficiency and acoustic insulation.
