How Does A Refrigerated Van Work?

In the United Kingdom, refrigerated vans play a pivotal role in the intricate web of the supply chain, with thousands of them traversing the roads to ensure the safe transport of goods that require specific temperature conditions. These vehicles are indispensable for preserving perishable food, consumables, and certain liquid medicines during transit.

At the heart of a refrigerated van is its airtight storage compartment, where a sophisticated cooling system diligently maintains the desired temperature. The primary objective is not only to transport items from point A to point B but also to prevent the degradation of sensitive goods by ensuring they remain chilled or frozen.

How Does It Keep Its Temperature

Key to the functionality of refrigerated vans is the use of high-grade insulation, far more effective than what one might find in a household refrigerator. Typically ranging between 50mm and 75mm in thickness, this insulation, often composed of a high-density polymer foam, creates a robust barrier against heat transfer. The insulation’s efficacy lies in its millions of tiny air bubbles that impede the movement of heat, whether the goal is to chill or freeze the cargo.

For chilling vans, a condenser is employed—a convoluted length of pipe containing a liquid coolant that absorbs heat efficiently. As the coolant warms, it transitions into a gas, circulating through the pipe until it reaches the compressor. The compressor then subjects the gas to extreme pressure, and as the gas returns to a liquid state, the heat is dissipated into the external environment, effectively maintaining the desired temperature within the cargo bay.

Crucially, the cooling system of these vans is not reliant on mains electricity but is powered directly by the vehicle’s driving mechanism. In cases where refrigerated vans are expected to remain stationary for extended periods, additional power sources, such as generators, can be incorporated.

How Long Do Refrigerated Trucks Last?

Refrigerated vans are designed for longevity, typically boasting a lifespan of seven years or more. These vehicles often come equipped with customisable shelving systems, maximising storage capacity to meet the unique needs of transportation businesses and end clients. The cooling system can be strategically placed on or within the van, depending on the manufacturer, with reputable companies like DAF, Iveco, Scania, Mercedes, and MAN producing models to suit various requirements.
