The comparison has to start with an accurate description of what each arrangement does. A refrigerated vehicle actively cools the body air; its energy arrangement depends on the vehicle and the unit. An insulated container stores the cold in advance: eutectic plates are prepared at the depot, the box is closed, and the round runs on the cold held inside. The decision therefore includes starting load temperature, target band, route and pack-out.

Where the reefer is strong

Long distance and full loads. Once the body is pre-cooled and the door stays shut, an active system can maintain one regime across a large volume. Intercity lines, plant-to-warehouse shipments and full loads to a single point are strong reefer profiles; the decision still needs the target temperature, starting load condition, drops and waiting time.

The Turkish Ministry of Education training module describes some installation examples: on bodies up to 5 metres the compressor is belt-driven from the vehicle engine, while bodies between 5 and 13.60 metres run the unit's own diesel engine. These examples show why the energy arrangement must be checked against the vehicle and unit; they are not one scheme for every vehicle.

Where the reefer weakens

The same module states the weakness just as plainly: when the door opens, cold air flows out along the floor and warm humid air takes its place, while the evaporator fan, still running with the door open, blows chilled air outside. For a round that opens the door twenty times a day, that is a systematic loss.

The second issue is scale: the cooling works for the whole body, so energy and usable-volume costs need to be checked on partial loads. The third is the calendar: seasonal work still carries fixed vehicle and maintenance costs. The fourth is continuity: a unit failure requires a backup, transfer or waiting plan.

Where the closed container is strong

Multi-drop rounds, partial loads, more than one regime on a route, and seasonal capacity. Because the cold sits inside the box, only the box being delivered is opened and the pack-out of other boxes can remain protected. The vehicle stays standard, remaining space can be assigned to dry goods, and the storage and re-preparation plan for the boxes must be included outside the season.

The limit of the closed container

The container has no active refrigeration unit. The GEBHARDT TBX brochure describes temperature protection for up to 24 hours. The 24-hour values in the table on GEBHARDT's plate page are freezing times; that page also gives an 8-24-hour preparation range depending on cooling technology. Preparation time and carriage time are different measures. Route, outside temperature, openings, plate type and quantity, starting load temperature and target band affect carriage duration. Re-preparation makes freezing-rack capacity and the cycle plan part of the purchase calculation.

Which one do the rules require

Do not decide from the equipment name alone. The Food Hygiene Regulation, quick-frozen food temperature-monitoring provisions and ATP text listed below address different scopes. Check the temperature, monitoring, documentation and contract requirements applicable to the load and route before quoting. Do not assume that one vehicle or container document covers every shipment.

Building your own decision

Put the longest trip duration, drops per round, cold volume per trip, target temperature, starting load temperature, waiting time and months worked per year into the same brief. Send them to Aris Makina and we will assess both arrangements against the same trip, pack-out and monitoring plan. The purchase decision then rests on an operable setup rather than the body type alone.
