How to choose refrigeration for food service

Refrigeration is the most expensive category to get wrong, because the cost of a failure includes the stock inside the cabinet. It is also the category where the cheapest purchase most often turns out to be the most expensive decision. A structured approach helps.

First decide: storage or display?

Cold storage and refrigerated display do two different jobs. Storage prioritises volume, temperature stability and efficient use of floor space. Display prioritises visibility, presentation and customer access. The same cabinet rarely does both well, and being clear about which you are buying saves a costly mismatch.

We list freezers from R6 820 to R88 956 and beverage coolers from R6 439 to R36 489 — the price spread within each reflects capacity and duty rating rather than brand alone.

Size against your delivery cycle, not your average stock

The most common sizing error is buying for average holding. If stock lands twice a week, you need more standing volume than a site restocked daily, because there is a point each week when the new delivery arrives before the floor has cleared. Undersizing here shows up as product stored in the wrong place at the wrong temperature.

Count the shelf metres or facings you need at your busiest trading hour and buy to that number. A unit that runs full works harder than one sized to the average, and that is the condition it needs to cope with.

Placement drives running cost more than the specification does

Where a cabinet stands affects the electricity bill more than most buyers expect. Ambient heat, poor ventilation and direct sunlight all push the compressor to run longer. Keep refrigeration clear of ovens, fryers and windows, give the condenser room to breathe, and stand the unit on a level floor so the doors seal and the drain runs correctly.

Check the plug point too. Refrigeration draws a start-up surge well above its running load, and sharing a circuit with other heavy equipment causes nuisance tripping that looks like a fault in the cabinet.

Door discipline

How often the door is opened matters as much as the rating. A unit on a busy service line loses far more cold air than one used for back-of-house storage, which is worth factoring into both the model and where you site it. Sliding doors need no swing clearance, which can be decisive in a tight aisle; hinged doors need room in front.

Maintenance that actually prevents failures

Three habits prevent most refrigeration call-outs:

• Brush the condenser coil clean on a schedule — dust on the coil is the single most common cause of a unit that no longer holds temperature
• Check door gaskets for splits and gaps
• Log internal temperatures daily so a slow drift is caught before stock is at risk

For bulk storage

Where volume outgrows cabinets, coldrooms and freezer rooms start at R53 356. These are projects rather than deliveries — floor construction, drainage, power capacity, door position and panel access all have to be confirmed on site before a quotation is final.

Common questions

What size commercial fridge do I need?

Size against your delivery cycle rather than your average stock. If deliveries land twice a week, you need enough standing volume to absorb a full delivery before the floor has cleared. Count the shelf metres you need at your busiest trading hour and buy to that.

Why is my commercial fridge not holding temperature?

In most cases it is a dirty condenser coil or a perished door seal, not a failed compressor. Both are cheap to check. Ambient heat and poor ventilation around the unit are the next most common causes, particularly where the cabinet sits near a cooking line.

Is an under-counter or upright fridge better?

Under-counter units save floor space and keep product within reach of the station using it. Upright cabinets give far more volume per square metre of floor. Busy service lines usually need both — under-counter at the station, upright for back-of-house holding.
