Reefer trucks: insulated van and PUF body

Reefer trucks, also known as refrigerated trucks, are crucial in transporting perishable goods like fruits, vegetables, dairy products, and pharmaceuticals while keeping them fresh and safe. These trucks’ insulated van or PUF body is key to maintaining the desired temperature throughout the journey.

Understanding Insulated Vans and PUF Body:

An insulated van or reefer truck body is specially designed to provide thermal insulation. It consists of several layers that help regulate the internal temperature, ensuring that perishable goods remain at their optimal conditions during transportation. These trucks are essential for industries where maintaining a specific temperature range is critical.

Production Stages of Reefer Truck Body:

1. Design and Planning: The production process commences with a detailed design and planning phase. Our engineers and designers collaborate to create blueprints that meet industry standards and exceed client expectations. Every detail, from size and capacity to insulation thickness and temperature control capabilities, is carefully considered, ensuring a product of the highest quality and reliability.

2. Material Selection: High-quality materials are crucial for building a reliable reefer truck body. The primary materials include insulated panels, typically made of PUF (Polyurethane Foam) sandwiched between durable outer layers. PUF is chosen for its excellent thermal insulation properties and lightweight nature, which helps optimize fuel efficiency during transport.

3. Panel Fabrication: Once the materials are selected, the panels are fabricated according to the design specifications. This involves cutting the panels to precise dimensions and fitting them together to form the truck body’s structure. Advanced machinery and skilled labor ensure accuracy in panel fabrication to maintain the integrity of insulation.

4. Insulation Installation: The next crucial step is installing insulation materials within the panels. PUF foam is carefully injected between the inner and outer layers of the panels, creating a thermal barrier that minimizes heat transfer. This insulation layer is the backbone of our product, ensuring stable internal temperatures regardless of external weather conditions and giving you the confidence that your perishable goods will reach their destination in optimal condition.

5. Assembly and Fitting: Panels are assembled and fitted onto the truck chassis after insulation. This process involves securing panels with specialized fasteners and ensuring a seamless fit to prevent gaps that could compromise insulation effectiveness.

6. Quality Control and Testing: Rigorous quality control measures and testing procedures are implemented before the reefer truck body is ready for use. Each truck undergoes comprehensive testing to verify temperature control performance, structural integrity, and overall functionality. This ensures that the truck meets industry standards and consistently maintains the required temperature range

7. Finishing Touches: Once testing is complete and the truck body passes all quality checks, finishing touches are applied. This includes painting, branding with company logos or client specifications, and installing additional features such as refrigeration units, temperature monitoring systems, and safety equipment.


The production process of a reefer truck body is not just a series of steps but a detailed journey that ensures the reliability and efficiency of the final product. This process, with its advanced materials like PUF insulation and modern manufacturing techniques, allows manufacturers to create insulated vans that meet the diverse needs of transporting perishable goods across various industries, thereby ensuring the freshness and safety of these goods.
