Long - term storage of refrigerated cargo vans is a topic that holds significant importance for businesses in the cold - chain logistics industry. As a supplier of refrigerated cargo vans, I've witnessed firsthand the various effects that long - term storage can have on these specialized vehicles. In this blog, I'll delve into the key aspects of how extended periods of inactivity can impact the performance, components, and overall lifespan of refrigerated cargo vans.
Impact on the Refrigeration System
The refrigeration system is the heart of a refrigerated cargo van. During long - term storage, several issues can arise. First, the refrigerant within the system can slowly leak over time. Even minor leaks can lead to a significant reduction in the cooling capacity of the unit. When the refrigerant level drops, the compressor has to work harder to achieve the desired temperature, which not only increases energy consumption but also puts additional stress on the compressor, potentially leading to premature failure.
Moisture can also accumulate in the refrigeration system during storage. This is because the system is designed to remove moisture from the air inside the cargo area. When the van is not in use, the lack of proper air circulation can cause condensation to form. Moisture in the system can react with the refrigerant and lubricants, leading to the formation of acids that can corrode the internal components of the compressor, valves, and pipes.
Another concern is the lubrication of the compressor. The compressor relies on a proper supply of lubricating oil to function smoothly. During long - term storage, the oil can settle, and the seals may dry out. This can result in insufficient lubrication when the compressor is restarted, leading to increased friction and wear on the moving parts.
Effects on the Body and Insulation
The body of a refrigerated cargo van is typically made of materials that are designed to provide insulation and durability. However, long - term storage can take a toll on these materials. Exposure to the elements, such as sunlight, rain, and humidity, can cause the exterior paint to fade, crack, or peel. This not only affects the aesthetic appearance of the van but can also lead to rusting of the underlying metal parts if the protective paint layer is compromised.
The insulation inside the cargo area is crucial for maintaining the desired temperature. Over time, the insulation material can degrade due to factors such as temperature fluctuations, moisture ingress, and physical compression. If the insulation loses its effectiveness, the refrigeration system will have to work harder to keep the cargo at the correct temperature, increasing energy consumption and potentially reducing the lifespan of the system.
Battery and Electrical System
The battery in a refrigerated cargo van is essential for powering the electrical components, including the refrigeration system. During long - term storage, the battery will gradually lose its charge. If the battery is not properly maintained, it can become deeply discharged, which can damage the battery cells and significantly reduce its lifespan.
The electrical wiring and connections in the van can also be affected by long - term storage. Moisture and corrosion can cause the wires to degrade, leading to electrical shorts or intermittent connections. This can result in malfunctions in the refrigeration system, lighting, and other electrical components.
Tire and Suspension
The tires of a refrigerated cargo van are under constant pressure when the van is in use. During long - term storage, the weight of the van can cause the tires to develop flat spots. These flat spots can lead to a rough ride and uneven tire wear when the van is put back into service. Additionally, the rubber in the tires can degrade over time due to exposure to oxygen, ozone, and UV radiation, reducing their overall performance and safety.
The suspension system of the van is designed to provide a smooth ride and support the weight of the vehicle. Long - term storage can cause the suspension components, such as springs and shock absorbers, to lose their elasticity. This can result in a harsher ride and reduced handling capabilities when the van is driven again.
Preventive Measures
To mitigate the negative effects of long - term storage, several preventive measures can be taken. For the refrigeration system, it's important to have the system inspected and serviced before storage. This includes checking for refrigerant leaks, ensuring proper lubrication of the compressor, and removing any moisture from the system. A professional technician can also add a desiccant to the system to absorb any remaining moisture.
The body of the van should be cleaned and waxed before storage to protect the paint from the elements. It's also advisable to cover the van with a breathable tarp to prevent direct exposure to sunlight, rain, and snow.
The battery should be disconnected and stored in a cool, dry place. It should be charged regularly to maintain its charge level. For the electrical system, all connections should be checked for corrosion and tightened if necessary.
The tires should be inflated to the recommended pressure and the van should be placed on jack stands to relieve the pressure on the tires. This can help prevent the formation of flat spots. The suspension system can be inspected for any signs of damage or wear, and if necessary, the components can be lubricated.
Conclusion
In conclusion, long - term storage of refrigerated cargo vans can have a range of negative effects on the vehicle's performance, components, and overall lifespan.
