Several Key Design Considerations for Containerized Diesel Generator Sets

With the improvement of social productivity and rapid economic growth, the demand for electricity is also increasing rapidly. Containerized diesel generator sets have emerged in recent years as a type of mobile power supply device, offering advantages such as easy mobility, good resistance to rain and dust, and relatively low noise. Below, we will explore several key factors to consider when designing a containerized diesel generator.

Compared to indoor-installed diesel generator sets, containerized generator sets have clear advantages in terms of project timelines: the approval process is relatively simplified, installation and commissioning cycles are shorter, and the reduced delivery time means faster capital recovery. The advantages of indoor installation include easier transportation of the unit, more space for maintenance, and a relatively smaller overall impact on the environment.

Regarding the key factors to consider when designing containerized generators in China today, we will elaborate on the following four points.

1. Power output and cable selection

As a power supply device, containerised diesel generators’ power output, types of cables and the wiring method should be considered. In addition to the diesel genset, the container also houses other low-voltage auxiliary equipment. Designers should clearly define the types of these devices and their power requirements before starting the design process. It is essential to reserve capacity and power interfaces for the mains supply in advance, as well as control cable connections.

2. Ventilation and heat dissipation

Generally, to reduce overall container noise levels and provide better protection, the noise-reducing enclosure is designed to be larger, which reduces airflow permeability. This can negatively impact the ventilation and heat dissipation of the entire unit. Therefore, when designing a container diesel generator, it is crucial to accurately calculate the intake and exhaust air resistance of the entire container to avoid exceeding the cooling system limits of the diesel generator set.

3. Day tank capacity

Typically, a day tank is installed inside the container. Unlike indoor-installed diesel generating sets, which are often limited to a 1m³ day tank, the day tank capacity for containerized diesel generators can be slightly larger.

4. Protection measures

Special attention should be paid to protective considerations for containerized diesel generator sets. In southern regions, the focus is on rainproofing, while in northern areas, additional measures such as protection against willow catkins, snow, cold, and insulation are necessary. For the fire protection system, a heptafluoropropane fire suppression system is commonly used inside the container. The fire protection system is often interconnected with the fuel supply system—when a fire alarm is triggered, it immediately issues an alert and rapidly discharges fuel from the day tank to prevent the fire from spreading further.

Consider diesel generators from Dingbo Power

At Dingbo Power, we provide different types of 100% brand new diesel generators, such as open-type, silent type, containerized type, trailer-mounted type, etc. Each type of generator sets have their advantages and disadvantages. You need to choose the right one based on your specific needs. Our containerized generators are packaged in ISO containers and the containerized line comes standard on a Department of Transportation (DoT) approved chassis.
