Insulated Van Design: Key Materials & Principles

When it comes to refrigerated companies, India offers most manufacturing units that use the key materials and principles to build insulated vans. Refrigerated trucks in India are in high demand for specialized cooling systems that keep fresh and sensitive goods secure during transportation. 

India’s extreme temperature fluctuations and high demand for fresh goods that are temperature-sensitive can only be solved with highly efficient refrigerated trucks. These trucks have some of the key elements, like refrigeration units, durable builds, and highly insulated structures to protect sensitive goods from spoilage. Hence, refrigerated trucks became an integral part of India’s cold storage logistics.

Let us now explore the key materials and principles of refrigerated truck containers.

Key Materials in Refrigerated Truck Containers

The key materials used to build the insulated containers and the structure of the containers are listed below.

Insulation Materials

The key materials required for excellent thermal insulation are polyurethane foam or PUF, polystyrene foam, and fiberglass. PUF is lightweight and resistant to thermal changes, so it keeps your trucks lightweight without impacting the efficiency of the trucks. Polystyrene foam is less dense while cheaper in cost and comes in two forms: expanded (EPS) and extruded (XPS). Fiberglass is cheaper and not moisture resistant like polystyrene foam and PUF.

Outer and Inner Panels

Refrigerated companies India has trusts aluminum, FRP or fiberglass reinforced plastic and stainless steel for their outer refrigerated containers’ structure. Stainless steel's durability and corrosion resistance help make it the best material for reefer trucks. 

Aluminum is lightweight, offers good thermal conductivity, and is resistant to corrosion, making it one of the best materials for building any refrigerated container structure that needs to maintain hygiene and temperature fluctuations. Similarly, FRP is durable and corrosion- and moisture-resistant, along with being lightweight.

Refrigeration Units

Refrigerated companies India have used evaporators, compressors, and condensers to create a stable temperature inside insulated vans. While evaporators absorb heat and transfer it to refrigerant condensers release the absorbed heat outside the vans. The compressor helps circulate refrigerant across the van for the cooling effect.

Sealants and Adhesives

Any refrigerated container’s structure requires special sealants and adhesives to create an airtight container. So air leaks are avoided and the temperature of the container remains stable.

Key Principles of Insulated Van Design

Here are the key principles of an insulated van that refrigerated companies India need to maintain to build an efficient reefer container or truck. 

Thermal Insulation

You need an insulated van because you want to protect your temperature-sensitive goods from temperature fluctuations during transportation. So, thermal insulation is essential when it comes to reefers. 

From the container walls to roof, refrigerated trucks in India are made using highly insulated materials like PUF insulation and PPGI (pre-painted galvanized iron sheets) to protect external heat from reaching the goods inside the container. This helps protect your goods from temperature changes.

Airtight Construction

Any insulated van needs to be airtight in order to protect the goods from external temperature. When a cold container is airtight, it doesn’t let warm and humid air enter the container and spoil fresh and sensitive goods inside. So, an airtight construction is especially essential around container doors to create a stable temperature inside the container. 

Temperature Control

Whether it’s reefer trucks or refrigerated trucks one of the key principles of refrigerated trucks is temperature control. Any insulated van needs to have a highly efficient refrigeration system to secure sensitive goods during transportation. 

Refrigerated companies India must instill reefer containers and trucks with advanced temperature control units to create stable conditions inside the van to ensure goods safety. Any cargo that is perishable in nature because of temperature sensitivity needs a refrigerated truck to protect its quality in fluctuating temperatures.

Load Management

India is a country of varied temperature, high humidity and high population that require high quality fresh goods daily. So, refrigerated trucks in India are built keeping in mind high loads of goods to meet the demand of perishable goods. Refrigerated companies India have to follow strict load management regulations with proper van design to maintain temperature integrity. This allows proper circulation in the van thus protecting goods from spoilage.

Energy Efficiency

Sustainability is essential in today’s world to protect our planet from any more carbon-based damage. So, building a sustainable insulated van is a must for refrigerated companies in India. Through energy-efficient cold storage trucks you can create an environmentally friendly operation that offers you both mental and financial peace. 

As you use less fuel for your transportation and deliveries, you save in fuel costs without compromising transportation efficiency. So, it's crucial for refrigerated companies India to create energy-efficient insulated vans. If you are searching for fuel-efficient refrigerated trucks or reefers, Sub Zero specializes in fuel-efficient reefer trucks. 

Hygiene and Maintenance

Fresh goods like milk, vegetables, milk products, seafood, and meat require the highest hygiene and moisture resistance during storage and transportation. So, these fresh goods don’t lose their value or quality, and consumers can enjoy the highest quality goods. Therefore refrigerated trucks use highly corrosive materials to protect the goods without affecting the structural integrity of the insulated van.

Conclusion

If you are looking for refrigerated trucks in India, Sub Zero offers you personalized and highly efficient cold storage solutions. From reefer trucks to cold storage units with advanced refrigeration systems, this Pune-based refrigeration manufacturer is leading in cold storage sectors with its products.

Similarly, they also offer vans integrated with modern technologies like real-time temperature monitoring systems and GPS. So, you must understand your requirements for insulated refrigerated trucks and ask your designed manufacturers to customize your refrigerated trucks for efficient deliveries across India.
