What is it built for

What Is a GRP Reefer Box Built For? Applications & Cargo Types

Designed for temperature-sensitive cargo across pharma, dairy, meat, frozen food, fresh produce, bakery, and last-mile EV deliveries. The lightweight GRP skin maximizes payload, while the reinforced sandwich panels make it rugged enough for harsh routes. Whether the application demands cooling, chilling, or deep-freeze, the insulation performance ensures temperature stability throughout transit.

How GRP Reefer Boxes Are Built — Materials, Insulation & Performance

Sub Zero's GRP reefer boxes are built using a single-piece GRP skin internally and externally. This construction removes joints and weak points normally seen in locally assembled bodies and improves strength under vibration and long-haul stress.

Internal reinforcements inside the sandwich panels add load-bearing capability for heavy-duty and high-volume operations.

The GRP skin itself provides superior insulation, reducing dependency on refrigeration energy and improving temperature hold duration during power-off scenarios.

Frequently Asked Questions

1.

What is a GRP reefer box?

A GRP reefer box is an insulated cargo body made with Glass Reinforced Plastic (GRP) panels. It is commonly fitted on reefer vans and refrigerated truck fleets to transport temperature-sensitive products safely.

2.

What are the advantages of a GRP reefer body over a steel body?

A GRP reefer body is lightweight, corrosion-resistant, and offers excellent insulation compared to steel. These benefits help improve fuel efficiency and make it a popular choice for many reefer companies.

3.

What temperature does a GRP reefer box maintain?

A GRP reefer box can typically maintain temperatures from –25°C to +25°C, depending on the refrigeration unit installed and the product being transported.

4.

What industries use GRP reefer boxes?

GRP reefer boxes are widely used in the food and beverage, dairy, seafood, pharmaceutical, floral, and cold chain logistics sectors that rely on reefer vans and refrigerated truck transport.

5.

Is GRP food-safe for use in refrigerated truck bodies?

Yes. High-quality GRP panels have smooth, non-porous surfaces that are easy to clean and maintain, making them suitable for food transport in a refrigerated truck when they meet industry standards.

6.

What is the difference between GRP and PUF panels in a reefer body?

GRP is the durable outer and inner skin of the reefer body, while PUF (Polyurethane Foam) is the insulation core placed between the panels. Together, they provide strength and effective thermal insulation.

7.

How long does a GRP reefer body last?

With proper maintenance, a GRP reefer body can last 10 to 12 years or more, depending on operating conditions, usage, and build quality. This long service life makes it a cost-effective option for reefer companies.

8.

How much does a GRP reefer box cost?

The cost of a GRP reefer box depends on the vehicle chassis, body size, insulation requirements, and the refrigeration unit selected. As an estimate, a GRP reefer body typically starts from around ₹3 lakh for smaller commercial vehicles and can exceed ₹10 lakh for larger truck configurations. The total cost of a complete refrigerated truck, including the chassis and reefer unit, varies based on your operational needs and specifications.

9.

Which vehicle chassis are suitable for a GRP reefer body?

GRP reefer bodies can be installed on a wide range of light, medium, and heavy commercial vehicle (LCV, MCV, and HCV) chassis, depending on the required payload and cargo volume. Smaller chassis are commonly used for urban and last-mile deliveries, while larger chassis are preferred for long-distance transport and high-capacity cold chain operations. The ideal chassis depends on your application, delivery route, and refrigeration requirements.
