The difference between the three routes lies in when the money leaves and what it is tied to. With renting the cost follows the trip; with buying it follows the calendar; with equipment it follows capacity. The right choice depends on which axis your business actually moves along.
Renting: cost tied to the trip
Renting does its job in short-term and unpredictable work. There is no fixed cost, maintenance stays with the owner, and the vehicle ageing is not your problem.
In exchange it has four limits:
- Unit cost is high; the daily rate earns the owner both their cost and their margin.
- Availability drops in the peak - everybody needs a vehicle in the same week.
- The vehicle is not built around your operation: shelving, compartments and interior fit-out are standard.
- Clauses on cooling failure, delay and product liability are usually written in the lessor's favour.
Buying: cost tied to the calendar
Buying lowers the unit cost if trip counts stay high all year. The vehicle is built around your operation, it is ready whenever you are, and the make and fit-out are your decision.
The limits are equally clear: depreciation, insurance, taxes and inspection run for twelve months; unit servicing and failure risk are yours; out of season the vehicle either stands idle or becomes a restricted dry-goods vehicle because of its refrigeration equipment. The unit's life is shorter than the vehicle's, so a second investment has to appear in the plan.
The third route: separating the cold from the vehicle
On this route the vehicle is a means of carriage, not a refrigeration system. Eutectic plates are frozen at the depot, the insulated container is closed, and the cold stays inside the box for the round. GEBHARDT puts the cold chain holding time for this arrangement at up to 24 hours with eutectic plates or dry ice.
In practice the consequences look like this: the vehicle stays standard and can be put on other work out of season; capacity grows with the number of boxes rather than vehicles; there is no line item called cooling failure, because a spare box carries on; and on the day the vehicle is in the workshop the round continues in another standard vehicle.
This route has conditions of its own: plate-freezing capacity at the depot, enough plate sets, and washing the boxes. The system asks for depot discipline.
The three side by side
| Criterion | Renting | Buying | Container arrangement |
|---|---|---|---|
| Shape of the cost | Follows the trip | Follows the calendar | Follows capacity |
| In the peak | Availability risk | Ready | Grows by adding boxes |
| Out of season | No cost | Fixed cost continues | Boxes on the rack, no cost |
| Effect of a failure | Replacement depends on the contract | The round stops | Carry on with a spare box |
| Fit to the operation | Standard vehicle | Full fit | Box size and regime are chosen |
| Long-distance full load | Strong | Strong | The 24-hour limit applies |
| Multi-drop urban | Weak | Medium | Strong |
Three numbers for the decision
- Trips per year: the unit cost of buying falls with this number.
- Season length: how many months are worked shows how long the fixed cost runs for nothing.
- Drops per round: the number of door openings decides which arrangement is physically suitable.
With those three in hand the decision stops being an argument. Send your figures to Aris Makina and we will calculate all three routes against the same round. Whichever of the three comes out ahead, the decision rests on the same trip calculation.
An intermediate step when switching
Most businesses that move to the container arrangement do not do it in one step. The common path is a pilot round with the existing vehicle: a few boxes, one set of plates and measurements across ten trips. Those ten trips show the cost per trip and the cold-holding time on your own route, and the decision is then made with a number.
