What Size Cooler Box Do I Actually Need?

Picking the right size cooler box matters more than it seems. Too small and you cannot fit your harvest; too big and you are paying to keep empty air cold, which also shortens the cold hold. Kold boxes come in three sizes — 50L, 120L, and 270L — and here is how to choose between them.

The three Kold sizes

• 50L — compact and portable. Best for individual vendors, small daily volumes, deliveries, and personal or restaurant use.
• 120L — the versatile middle. Good for a busy market stall, a small farm's daily harvest, or regular transport runs.
• 270L — high capacity. Built for larger harvests, bulk cold transport, cooperatives, and distributors moving serious volume.

How to choose the right size

1. Estimate your volume. How much produce do you need to hold at once, on a typical and a peak day?
2. Think about the use case. Overnight storage, a full market day, transport, or all three?
3. Consider handling. Will you carry it yourself, or move it by vehicle? A 50L is easy to lift; a 270L is for vehicle transport.
4. Aim to pack it full. A well-filled box holds cold longer than a half-empty one, so size to your actual load.

Why a full box works better

A cooler box holds cold best when it is packed. Empty space is just air the PCM has to keep cold, which drains the cold hold faster. Choosing a size that matches your real volume — rather than the biggest box available — actually keeps your produce colder for longer.

Not sure? Rent flexibly

Because Kold boxes are rented by the day or week, you are not locked into one size forever. Many customers use a smaller box day to day and rent a larger one — or several — during peak harvest. You can match the box to the season instead of guessing once and living with it.

Bottom line

Match the box to your real produce volume and how you will move it: 50L for small, portable needs, 120L for a busy stall or small farm, 270L for bulk and distribution. When in doubt, size to pack the box full, and remember you can rent up during peak season.
