Silent Diesel generator set advantages
1. Low Noise. This is the most significant feature of the silent generator. It reduces noise generation and transmission through the use of soundproof materials, sealing design and special noise reduction technology.
2. Compact Structure. Silent diesel generator sets are usually compact in design, easy to install and move.
3. Efficient Performance. Even use of noise reduction measures, this type of generator set usually still maintains efficient power output.
4. Durable. Silent generator sets usually use high quality materials and components to ensure its reliability and durability in harsh environments.
5. Easy to Maintain. These generator sets are usually designed with ease of maintenance in mind, making regular inspection and maintenance work easier.
6. Environmental Protection. Due to lower noise levels, silent generators are more environmentally friendly, suitable for areas with more stringent noise restrictions.
7. Multifunctionality. Silent diesel generator sets can not only be used in home, commercial and industrial environments, but also for field working and emergency rescue.
8. Temperature Adaptability. Some silent generator sets are designed with temperature control devices, which can operate stably at different ambient temperatures.
9. Intelligent Control. Modern silent diesel generator sets are usually equipped with intelligent control systems, which can realize remote monitoring and fault diagnosis.
10. Energy Saving. Silent generator sets have a relatively low fuel consumption rate, which helps to save energy.

It can be used as the main power source and run continuously to provide uninterrupted power supply for various civil and industrial power equipment. The main components are selected from top international brands with high reliability, safe and stable performance. The intelligent parallel control system can perform parallel operation of multiple units to meet the power demand of larger loads.

The advanced waterproof and dustproof design adopts a labyrinth type air duct structure and a dustproof net design, while adding sealing strips and applying sealant to balance the different needs of ventilation and waterproof and dustproof. Meanwhile, it has been repeatedly tested in rain and dustproof tests, the highest can reach the protection level IP54.

High quality steel is used for the cabinet and surface spray treatment, corrosion resistance, scratch resistance, rust resistance, it can meet the C4, 05-1 and C5M class anticorrosion requirements according to different use environments, the surface treatment process of the diesel genset has passed the 1500 hours salt spray test.

Radiator and high voltage parts are isolated and protected to avoid accidents caused by touching, there are emergency stop buttons inside and outside of the cabinet for convenience and safety, and the negative battery switch on and off DC control power supply, and it has a lockable fuel cover.

Through the three dimensional construction analysis simulation software on the generator set load bearing and vibration calculations and long time running tests, effectively reduce the genset running vibration, to ensure stable and reliable working.

The fully enclosed noise reduction system, advanced product design and manufacturing process to ensure better stability of the engine, thereby getting the lower body noise and exhaust noise, in addition to use of sealing rubber around the door, the concept of noise reduction is also fully integrated into the entire intake and exhaust system and all other components.

Here are several key features of silent diesel generator sets conponents:
1. Galvanized sheet steel cabinet, corrosion and fire resistant with abrasion and tear resistance function.
2. High strength base, low vibration, stable work.
3. Forklift lifting holes and top lifting lug for easy transportation.
4. Large capacity base fuel tank for long time use.
5. External fuel filler for easy to refuel.
6. Air inlet, make sure there's enough air in.
7. External coolant filler for easy injection.
8. Full featured control system to meet different types of customer needs.
9. Exhaust with rain cap to protect the genset.
10. External emergency stop button, its primary function is to immediately shut down or stop working of a machine or system in an emergency situation to prevent damage to equipment.
