Insulated highway trailers with active temperature-control systems for single- or multi-temperature freight.
Start with the product temperature, loading pattern and delivery cycle. A refrigerated trailer combines an insulated body with an installed temperature-control system; the body model and the refrigeration-unit model answer different questions. Refrigeration should be selected around the cargo and operation, not simply the presence of a front-mounted unit.
| Decision | What changes | Ask for |
|---|---|---|
| Single or multiple temperature zones | Mixed freight may require partitions, remote evaporators and a verified airflow arrangement. A movable bulkhead alone does not prove that separate temperatures can be maintained. | Zone layout, evaporator arrangement, bulkheads and unit capability |
| Linehaul or frequent deliveries | Door openings, dwell time and loading practices affect the thermal task. Rear-door geometry and optional side doors must be assessed alongside the temperature system. | Delivery cycle, door openings, return-air path and cargo loading plan |
| Power and body condition | Standby power, heating, fuel supply and refrigeration controls are installed-system details. Insulation condition and door seals matter independently of the unit hours. | TRU model/service record, power options and body/insulation inspection |
Cold ambient weather does not eliminate the need for temperature control: some freight needs heat or freeze protection. Establish the loading temperature, washout expectations and monitoring responsibilities for the actual commodity. A reefer container on a chassis remains an intermodal configuration.
For route-specific checks, start with the applicable provincial authority. Alberta permit resources ↗ and Ontario permit resources ↗ explain their respective processes; neither is a Canada-wide clearance rule.

3 specification references cover 1 trailer architecture. Open the specification library for model-specific documentation.
Model references are supported by manufacturer documentation. Check each configuration for its available dimensions and ratings.
Each reference shows the feature that controls classification. It is not a dimension, rating, compatibility or availability source.
Zone count is established by the documented interior partition and airflow system. The TRU is an installed system, not the trailer body identity by itself.
One controlled cargo zone served by the documented airflow system.
A physical partition and secondary evaporator create separately controlled zones.

An insulated highway trailer with a documented active temperature-control system is canonical here; the refrigeration equipment remains a separate installed component.
