How Much Cold Storage Space Do You Actually Need?

How Much Cold Storage Space Do You Actually Need?

Most buyers arrive at a cold store with a number in tonnes and leave with a quote in pallet positions, and nobody in between does the conversion honestly. So they guess. Guess high and you pay every month for space you never fill. Guess low and you find out in your busiest week, splitting a consignment across two buildings on opposite sides of the city.

The arithmetic is not hard. Here is the version we would walk you through on the phone.

Work in pallet positions, not tonnes

A cold store's cost is space, not weight — the chamber is the same chamber whether your pallet holds 400 kg of bakery product or 1,100 kg of frozen fish blocks. Your rate will be charged against a position, so size yourself against positions too.

You only need one measurement to start. Build one representative pallet of your own product, stacked to the height the store racks to, and count the cartons on it. That gives you your own cartons-per-position figure, which is worth more than any industry average, because your product's density and your carton dimensions are yours and nobody else's. Ask the store its clear height per racked level before you build it — a pallet built to 1.6 m when the store racks at 1.4 m is a pallet that gets restacked on the dock, at your cost and on your time.

The formula

Once you are counting in pallets, this is all of it:

Positions = (pallets in per month ÷ 30) × average days of cover × peak factor, then ÷ 0.9

Take an FMCG super-stockist moving 400 pallets a month through Kochi. That is about 13 pallets a day inbound. Hold an average of 21 days of cover and you need roughly 280 positions standing at any given moment. Now the peak: Onam and the December–January run are not average months, and a 1.4 factor is not unusual — that takes you to 392. Finally divide by 0.9, because a chamber at 100 per cent occupancy has nowhere to put the next pallet and nowhere to work. Call it 435 positions.

Run it on your own numbers before you take anyone's recommendation, ours included. If a store's suggested figure comes back more than about 20 per cent above yours, ask which assumption it is carrying.

Days of cover is the number worth arguing about

Everything else in that formula is a fact about your business. Days of cover is a decision, and it is yours, not the cold store's.

Going from 28 days of cover to 21 takes a quarter off your positions and a quarter off your monthly bill. It is also the single change most likely to fail badly — if your inbound is a container that arrives when it arrives, cover is your buffer against a sailing that slips. The right answer is not the lowest one. It is the lowest one your inbound reliability can actually support, and it is worth writing down which of those two you have chosen, because in six months nobody will remember.

Chilled or frozen, and how much of each

Most buyers need both, and almost all of them underestimate the chilled side — then discover that what they needed was never storage at all, but somewhere to put product that is waiting. Waiting for a vehicle. Waiting for a QC release. Waiting to be tempered, re-labelled, or picked down into a smaller order.

The two are different problems for the building. Deep-freeze is long dwell, few door openings, and a temperature floor you cannot negotiate with — frozen fishery product going to the EU must be held at not more than −18 °C in all parts of the product, under Regulation (EC) 853/2004, Annex III, Section VIII. Chilled staging is the opposite: short dwell, constant movement, and a door that opens all day.

Troveful ColdVault is built as 2,000 pallet positions = 1,890 racked (3 chambers × 630) + 110 chilled in the ante room. Set that against your own split before you enquire. If your chilled requirement is genuinely primary storage rather than staging, say so in the first conversation — it is a different discussion, and it is much better had early than after a quote has been written.

What the number does not include

Three things people leave out and then need anyway.

Blast freezing. It occupies space, but it is a process, not storage, and it is normally priced separately. If your product arrives unfrozen, it needs its own allowance.

Quarantine and rework. Damaged stock, held lots, a batch sitting on a test result. A handful of positions, permanently occupied, and always more than you planned.

Empties and dunnage. Pallets come back. They have to live somewhere, and somewhere is usually inside.

Then check the positions are the positions you think they are

A racked position and a floor-stacked pallet are not the same product, and both get called "a pallet" in a quote. Racked means selective access — you can pull any one pallet without moving another, which matters the moment you run FIFO or need lot-level traceability for an audit. Floor stacking is cheaper per pallet, slower to pick from, and capped at whatever stack height your own cartons will bear without crushing. When you compare two quotes, confirm in writing which one you are being quoted, because the gap between them is not small.

Bring your numbers and look at the building

The fastest version of all of this is twenty minutes on site with your own throughput figures in hand. Come and see a chamber, look at what one racked position actually holds, and we will do the arithmetic with you — including the part where the answer is that you need less space than you thought.
