If you have ever seen a large white “refrigerated truck” with a visible cooling unit mounted at the front and wondered what exactly you were looking at – most likely, it was a refrigerated semi-trailer. The truck itself is the tractor unit at the front; the “box” behind it is the semi-trailer, where the cargo is loaded and where temperature control is maintained.
For food products, pharmaceutical goods, cosmetics and other temperature-sensitive cargo, the right equipment – and the processes around it – are critical. That is why N&N Transport Logistics operates refrigerated transport as a dedicated, controlled service line – with structured capacity planning, monitoring and documented reporting.
1) The trailer body
This is the insulated box structure carrying the cargo. Brands such as Schmitz Cargobull typically manufacture the trailer itself – including chassis, doors and insulation system. It is precisely the insulation and structural integrity that ensure stable temperature performance during transit.
2) The refrigeration unit – the cooling system
Mounted at the front of the trailer is the refrigeration агрегate, often produced by Thermo King or Carrier. It is the core component managing cooling and freezing functions. In our fleet, you may see models such as Thermo King A-500 Spectrum or Carrier units on selected trailers.
Inside the trailer, ceiling evaporators distribute cold air evenly. Certain configurations also include an internal partition (bulkhead), which enables dual-temperature transport operations.
This solution is typically used when:
Typical industries and use cases:
Food & FMCG – fresh, frozen, dairy, chocolate products, seasonal campaigns and peak volumes.
Pharmaceutical & cosmetics – manufacturer-specified temperature ranges and documented traceability requirements.
Retail / HoReCa / e-commerce – scheduled deliveries, promotional logistics, tight receiving windows and high predictability standards.
At N&N Transport Logistics, the service is built upon:
Route – loading/unloading locations + preferred date/time window
Cargo type – chilled / frozen / pharmaceutical / cosmetics and sensitivity level
Temperature regime – set point and acceptable deviation range
Volume – pallets / cartons, total weight and cubic volume
Dual-temperature requirement (if mixed cargo)
Loading/unloading method – dock, side loading, high-volume trailer, site restrictions
Documentation requirements – temperature logs, client-specific rules, customs coordination if applicable
Urgency – standard service or express transport
The more structured the input, the more predictable the logistics outcome – both in terms of pricing and execution.
Refrigerated semi-trailers are part of a broader cold chain system in which equipment, procedures and monitoring operate as an integrated framework. When transporting food, pharmaceuticals or sensitive goods, partner selection should be based on capacity, control and documented compliance – not assumptions.

What exactly is installed on these trailers?
In the gallery below, you will see two main components that are often confused:1) The trailer body

What does “dual-temperature trailer” mean and when is it important?
A dual-temperature trailer allows two independent temperature zones within a single transport movement. For example, refrigerated transport of combined chilled and frozen cargo. This is achieved through internal partitioning and independent zone control, preventing thermal interference between product categories.This solution is typically used when:
- you operate mixed cargo profiles (e.g., chilled dairy + frozen products);
- you aim to optimise transport costs by consolidating into one trip instead of two;
- you manage retail supply chains where mixed product loads are standard practice.
When do businesses use refrigerated trailers?
Refrigerated transport is typically required in two scenarios – when the product legally or technically requires temperature control, or when the client requires documented temperature compliance, particularly on longer or international routes.Typical industries and use cases:
Food & FMCG – fresh, frozen, dairy, chocolate products, seasonal campaigns and peak volumes.
Pharmaceutical & cosmetics – manufacturer-specified temperature ranges and documented traceability requirements.
Retail / HoReCa / e-commerce – scheduled deliveries, promotional logistics, tight receiving windows and high predictability standards.
N&N Transport Logistics capacity in refrigerated transport
Professional refrigerated transport requires more than a single vehicle. It requires scalable capacity capable of handling seasonality, campaigns and diverse temperature profiles.At N&N Transport Logistics, the service is built upon:
- 120 double-deck dual-temperature semi-trailers
- 10 specialised refrigerated high-volume trailers
- 24/7 monitoring with alarms and documented temperature reports upon request
- SOP-based loading/unloading procedures, validated equipment and scheduled calibration (as part of strict cold chain discipline)
What information should you prepare to receive an accurate quotation?
The most common reason for inaccurate quotations is insufficient shipment detail. To receive a precise rate and realistic transit timeline, prepare the following information in a structured request:Route – loading/unloading locations + preferred date/time window
Cargo type – chilled / frozen / pharmaceutical / cosmetics and sensitivity level
Temperature regime – set point and acceptable deviation range
Volume – pallets / cartons, total weight and cubic volume
Dual-temperature requirement (if mixed cargo)
Loading/unloading method – dock, side loading, high-volume trailer, site restrictions
Documentation requirements – temperature logs, client-specific rules, customs coordination if applicable
Urgency – standard service or express transport
