Diesel generators have always been considered the most reliable and low-cost power equipment.

They provide powerful power support for residential, commercial, and industrial applications, and are not affected by weather and the use environment.

However, the high noise level of diesel generators has always been a concern for users when purchasing, especially for residential and commercial customers.

Therefore, the demand for silent diesel generators in the market has soared.

For every 100 diesel generators sold, silent diesel generators account for more than 60%.

If you are also looking for reliable portable or industrial silent diesel generators, this article will guide you when choosing and purchasing, helping you to choose the right Chinese silent diesel generator easily

WHAT IS A SILENT DIESEL GENERATOR?

These diesel generators use soundproofing materials and advanced reduce-noise technology to minimize the noise effect, making these diesel generators suitable for residential, and commercial buildings, etc which have high low-noise environment requirements.

HOW DOES THE SILENT DIESEL GENERATOR WORK?

Work by the diesel engine to drive the brushless alternator, converting kinetic energy into electrical.

A good silent diesel generator includes below key points

• Reasonable structural design
• Environmentally friendly, flame retardant, high thickness sound-absorbing cotton
• Quality diesel engine
• Residential mufflers

WHY CHOOSE GENERATOR SET DRIVEN BY DIESEL?

• Fuel Efficiency: diesel generator generally provides higher fuel efficiency than gasoline generators. Longer burning time and lower cost of use.
• Durability: diesel generators are more durable, have lower failure rates, and have longer service life than gasoline generators.
• Power Output: diesel generators produce higher output power than gasoline generators and can meet the application of different fields such as home, residential, construction, commercial, and industrial purposes.
• Easy of Use: Not affected by weather conditions, can be used at any time.

BENEFITS OF SILENT DIESEL GENERATOR

Low Noise Levels:  work at lower noise levels, often below 65 dBA, making them suitable for use in residential, commercial areas hospitals, and schools.

Reduced Environmental Impact: Most silent diesel generators are equipped with eco-friendly technologies and diesel engines that reduce emissions, making for a cleaner air environment.

KEY FACTORS WHEN CHOOSING A SILENT DIESEL GENERATOR

1. Output Power

Calculate the total power you need in KW or KVA for your all connected equipment.

Please be attentive, some appliances require more power to start up.

Such as air conditioners, refrigerators, water pumps, etc.  

2. Noise Level

The noise level of a diesel generator depends on the capacity of the diesel generator.

The larger the output power, the noise is higher. Usually, we advise the buyer/users to tell the manufacturer about the installation or use environment before purchasing.

If have high requirements for the noise, we will recommend more suitable models.

3. Portability

If the silent diesel generator requires frequent moves for outdoor activities, work sites, and other environments, choosing a trailer will make it easier to move and use.

We have models that can be pushed by a single person below 20kVA diesel generators and models that can be installed on mobile trailers below 500kVA for selection.

4. Fuel Tank Capacity

The fuel tank capacity of the diesel generator is determined according to the daily or weekly usage time.

Generally, we recommend reserving 20% of the capacity based on the basic usage time as an emergency standby.

When an emergency occurs and the diesel generator can’t be refueled in time, the necessary emergency power can be ensured.

For example, a 30kW diesel generator with a standard 60-liter fuel tank can continuously run for 12 hours at 75% load.

If power outages are frequent or the diesel generator is installed in a remote location, we recommend a large fuel tank 200 liters, or larger fuel tank.

5. Quality Cooling Performance

The cooling performance of a silent diesel generator is also important.

Since the silent diesel generator is wrapped in a completely enclosed steel canopy, the calculation of the air intake and exhaust volume during the design of the generator set will directly affect the heat dissipation of the silent diesel generator.

Poor heat dissipation performance will cause the engine cylinder to overheat and cause mechanical failure.

Excessive exhaust volume will increase the decibel of noise, so it is important to choose a diesel generator set manufacturer with rich manufacturing experience.

6. Ease of Operation

• Control Panel: It should be easy and simple for you to operate the diesel generator and adjust settings.
• Remote Start & Monitoring: all models offer remote start options, allowing you to start and monitor the generator from a distance, which is particularly useful in inclement weather and remote locations.

7. Basic Safety Protection Functions

• Low Oil Protection: When the oil in the generator is insufficient or reaches the warning level, the generator set will issue a low oil pressure alarm and shut down to prevent mechanical failure caused by lack of oil.
• High Water Temperature Protection: When the water tank temperature of a diesel generator set reaches above 98 degrees, the generator control module will issue a high water temperature warning and then shut down for protection to prevent the water tank from overheating and causing damage to the equipment.
• Over Current Protection: When the user’s load exceeds the rated current of the generator set, the generator set will issue a shutdown alarm to prevent excessive current from causing damage to the equipment.
• Over Load Protection: When the user’s load exceeds the rated power of the generator, the generator will also issue an alarm and shut down to prevent the equipment from overloading due to excessive load.

8. Warranty and Technical Support

Consider the manufacturer whether can provide complete technical services and after-sales warranty in your country.

9. Brand Reputation

Some of the top names in the diesel generators include:

• Cummins Onan
• Kohler
• Generac
• WALT
• SDMO
• ATLAS

MAINTENANCE TIPS FOR SILENT DIESEL GENERATORS

1. Regular Change the Oil

Changing the oil regularly is essential to maintain engine health. Follow the manufacturer’s recommendations for oil type and change intervals.

2. Keep The Genset Clean

Dust and debris can negatively affect the performance of your generator. Regularly clean the exterior, including the air filter and cooling vents, to ensure enough intake and exhaust airflow.

3. Regular Check the Fuel System

Regularly inspect the fuel tank and pipelines for any leaks or blockages. Ensure that you use clean diesel fuel to prevent clogging the system.

4. Battery Maintenance

Regularly check the battery. Ensure it is charged in full and in good condition to avoid startup failure.

5. Run It Regularly Per Month

It’s a good idea to run your silent diesel generator every month for 20-30 minutes at 25% to 50% load. This helps keep the engine lubricated and prevents fuel from degrading.

6. Winterizing

If you’re using your generator in cold climates, consider adding heaters for your diesel generators to ensure normal use.

CONCLUSION

Choosing the right silent diesel generator will provide a good use experience during power outages or outdoor operations. A good silent diesel generator set is not only a power equipment you need in your daily life, but also a reliable friend.
