- Product Description
JLMECH：Your Trusted Closed Frame Diesel Unit Manufacturer & Supplier
As an established generator manufacturer with over 20 years of industrial experience, our factory specializes in developing enclosed power solutions that deliver reliability in challenging conditions. Our Closed frame diesel unit integrates a durable protective enclosure with high-performance power generation, creating an ideal solution for applications where equipment protection, safety, and longevity are essential considerations.
Closed Frame Diesel Unit Advantages
All-Weather Enclosure Design: Our Closed frame diesel unit features a robust steel frame with IP23 protection, effectively shielding internal components from rain, wind-blown debris, and accidental contact while ensuring adequate ventilation for optimal performance.
Noise Reduction Technology: The integrated acoustic panels and engineered airflow system reduce operational noise to approximately 70-75 dB(A) at 7 meters, making the unit suitable for use in noise-sensitive areas such as residential neighborhoods, hotels, and hospitals.
Security and Vandal Resistance: Lockable access doors and reinforced panels prevent unauthorized entry and protect critical components from tampering or theft, providing added peace of mind for unattended installations.
Corrosion-Resistant Finish: A multi-layer powder coating offers superior resistance to rust, UV exposure, and chemical agents, ensuring long-term durability in coastal, industrial, or high-humidity environments.
Simplified Maintenance Access: Strategically placed service panels and removable sections allow easy inspection, filter changes, and routine servicing without requiring full enclosure disassembly.
