Choose portable cold room size by working backward from peak inventory and the way products are handled. External volume is not internal volume, and internal volume is not usable storage volume. Insulation, refrigeration equipment, shelves, aisles and air clearances all take space.

Start a FLAND small mobile cold room selection with a real loading layout: establish how products fit and remain accessible, then match refrigeration and site handling.

Separate peak inventory from daily intake

List daily deliveries, collection intervals and seasonal peaks for each product. Estimate the largest simultaneous inventory, then add a justified business allowance. Average stock can hide a capacity problem when deliveries arrive together and customers collect later.

Record the temperature of new arrivals as well. Refrigeration sizing must account for product cooling and other heat loads, rather than a simple room-volume-to-horsepower rule. Include incoming temperature, door activity and ambient conditions in the selection brief.

Replace vague tonnage with a loading layout

Supply the dimensions, weight and stacking limitations of the actual crates or cartons. Ask for a layout showing how they fit, rather than accepting an unexplained capacity in tonnes.

Worked example: planning 72 crate positions

A hypothetical small farm handles 24 crates per day, with a maximum two-day stay and a 50% inventory allowance. The planning quantity is 24 × 2 × 1.5 = 72 crates. A proposed arrangement of six crates per shelf, four shelves per rack and three racks provides 72 positions.

That verifies the count, not the room or refrigeration selection. Crate dimensions, shelf ratings, top clearance, aisle width, doorway access and airflow still need checking. If each crate contains 10 kg, total planned stock is 720 kg, while the cooling duty for 240 kg of daily arrivals remains a separate calculation. These figures illustrate a layout method; they are not a product capacity claim.

Holding and precooling lead to different requirements

With precooled arrivals, the main task is maintaining temperature. Produce arriving with field heat needs that heat removed within the available time. Additional fans cannot replace sufficient refrigeration capacity. UVM's farm forced-air cooling guidance demonstrates the importance of directing air through produce in small-scale postharvest work.^[1]

For a rapid-cooling application, specify initial temperature, target product temperature and the time available. For holding storage, state the expected receiving temperature. This prevents a supplier and buyer from assuming different duties for the same room.

Check the handling route, not only the footprint

The door must accommodate the real cart or package. Allow turning and door-swing space outside, plus ventilation and service access around the refrigeration equipment. For future relocation, confirm approved forklift or lifting arrangements, center of gravity, empty-transport requirements and access routes. A movable enclosure is not automatically intended to be moved while loaded.

Ask the operator to review the layout before ordering. A room that technically fits the stock can still be frustrating if staff must unload several crates to reach every order. Access requirements may justify more aisle space and fewer nominal positions.

Turn the crate plan into a workable FLAND configuration

For the illustrative 72-crate requirement, give FLAND the crate dimensions, weight and shelf arrangement, then use FLAND modular cold rooms configurations to check internal space, door access and equipment intrusion. For relocation, confirm the relevant mobile model’s base, handling and transport requirements.

The practical value of a small room is organized storage within limited space. A monoblock arrangement can reduce field piping work, while ventilation and service access remain necessary. Compare assembled delivery with disassembled shipping against the entrance, transport and local assembly conditions.

Frequently asked questions

Can I size the room using kilograms per cubic meter?

Use that only for rough screening. Packaging density, stacking, aisles and product type vary. Confirm the actual layout before purchase.

Will the next room size up cool products faster?

Not necessarily. Effective refrigeration capacity, airflow, packaging and batch size determine cooling performance.

Should I choose a single or double door?

Base the decision on handling equipment, package dimensions and access frequency, while accounting for the heat load from openings.
