WHAT IS A GENSET CHASSIS? APPLICATION AND HOW IT WORKS

26 Feb, 2025

In the ever-evolving landscape of power generation, the genset chassis stands out as a critical component for ensuring efficiency and reliability. Whether you are considering investing in a genset chassis for sale or exploring the benefits of a chassis with genset configurations, understanding these structures is vital for optimizing your power solutions. Therefore, in this article, Thaco Trailers will provide an in-depth look at what a genset chassis is, its various applications and how it operates.

What is a genset chassis?

A genset chassis is a vehicle frame or trailer designed including genset. This type of chassis is critical for supplying power to reefer containers. It ensures that these refrigerated units can function properly when there is no access to standard shore power. Gensets are frequently used to provide energy for long-distance shipping or to maintain sensitive commodities, such as medications or food supplies, at specific temperature levels. Most gensets are constructed as clip-on units that attach to the upper front of the reefer container for quick connection and separation. Alternatively, underslung gensets installed on a normal chassis frame beneath the container provide a more integrated and sturdy alternative.

Genset operating principle

The genset operates through a series of coordinated processes that convert fuel into electrical energy, ensuring a reliable power supply for refrigerated transport. Typically, it employs an internal combustion engine powered by diesel, natural gas, gasoline, or propane, which produces mechanical energy. When the engine runs, it spins a shaft connected to a generator.

The generator itself consists of a stator and a rotor. The rotor spins inside the stator’s magnetic field, inducing an electric current through electromagnetic induction, thus generating an alternating current (AC) output. For the genset to function effectively, it must provide stable voltage output that meets the power requirements of connected devices. A voltage regulator monitors and adjusts the voltage output by modifying the excitation of the rotor’s field winding, ensuring a consistent power supply.

Since gensets generate significant heat and exhaust gases, they are equipped with cooling and exhaust systems to prevent overheating and safely remove combustion gases from the engine. Additionally, the control panel plays a critical role in managing and monitoring the genset’s functions, including starting and stopping the engine, regulating voltage, and checking fuel levels and temperature. Some models even feature automatic transfer switch (ATS) capabilities, which enable seamless transitions between grid power and genset power during outages. This integrated operation guarantees that gensets deliver reliable power for temperature-sensitive cargo throughout its transport journey.

Genset application for containers

Gensets ensure refrigerated containers maintain appropriate temperatures by supplying consistent power to preserve sensitive cargo during transit. Gensets can be implemented in a variety of ways, including clip-on gensets, which are mounted directly onto the containers for easy access; underslung gensets, which are placed alongside the containers to maximize space utilization. They can be a part of a containerized power station, which provides a centralized power solution. These applications are critical for maintaining the quality of temperature-sensitive goods while they travel.
