Where to Put a Commercial Fridge: Placement, Ventilation and Room Temperature

Where you put a commercial fridge makes a real difference to how well it works. Put it in a hot corner with no room to breathe and it runs longer, costs more, struggles in summer and wears out sooner. Give it the right spot and it holds temperature easily for years. This guide covers ventilation and clearance, room temperature and humidity, heat sources to avoid, and practical placement for kitchens, bars and shops.

The short version

Leave the clearance around the cabinet that the manual asks for, and keep the condenser grille clear.
Keep fridges away from ovens, fryers, grills, dishwashers and direct sun.
Choose a fridge rated for the hottest temperature your room reaches.
Stand it on a level floor, plugged straight into a wall power point.
Put it where staff use it most, with room for the doors to open fully.

Why placement matters

A fridge doesn't make cold. It moves heat out of the cabinet and releases it into the room through the condenser. If that heat can't get away, because the fridge is boxed in, pushed against a wall or sitting next to an oven, the fridge has to work harder to do the same job. You pay for that in higher power bills, a fridge that can't hold temperature on hot days, and more wear on the compressor and fans.

Ventilation and clearance

Follow the manual's clearances

Every model lists how much space it needs around the sides, back and top. Use those figures, not a rule of thumb, because they depend on where the condenser sits and how air moves through it.

Know where your fridge breathes

Bottom-mounted compressors usually draw air through a grille at the front, near the floor. Keep that grille clear of boxes, mats and mop buckets.
Top-mounted compressors release heat at the top. Don't stack stock or boxes on top of the cabinet, and don't fit it under a low shelf or bulkhead.
Underbench fridges built into joinery need to be a front-breathing model, or the joinery needs ventilation openings. A rear-venting fridge boxed in under a bench will overheat.

Give fridges side by side some room

Two fridges jammed together can blow warm air into each other. Leave the gap the manuals ask for, and don't line fridges up so one's exhaust feeds the next one's intake.

Watch out for small rooms

A fridge in a cupboard, storeroom or small back room can heat that room up quickly. If the room has no air-conditioning or ventilation, the temperature around the fridge can climb well past what it's rated for.

Room temperature: check the rating

Every commercial fridge is designed for a maximum room temperature, and the figure varies a lot between models. In our range, for example, the NovaChill flower fridges are rated for rooms up to 43°C, the Crusader flower fridges up to 38°C, and the Bonvue SC120FA-2XB cake display up to 32°C and 60% humidity.

A busy kitchen behind the cooking line, a shopfront with afternoon sun or a bar with no air-conditioning can easily pass 32°C in summer. Check the temperature in the spot you have in mind on a hot afternoon, and choose a fridge rated above it. If it isn't rated for that room, it will run flat out and still struggle.

Humidity

Humid air brings condensation on glass doors, frost inside the cabinet and water on the floor. It's worst near the coast, in summer and near steam sources. Air-conditioning helps because it dries the air as well as cooling it. Heated or anti-fog glass helps display fridges in humid spots. Our guide to reducing condensation in display fridges covers it in detail.

Heat sources to avoid

Ovens, ranges, fryers, grills and salamanders
Dishwashers and glasswashers, which give off heat and steam
Coffee machines and bain-maries
Direct sun through windows and glass shopfronts
Heaters, and the hot exhaust from other equipment

If a fridge has to go near a heat source, leave as much space as you can and choose a model with a higher room temperature rating.

Placing fridges for how you work

Kitchens

Put prep and underbench fridges where the cooks use them, but not right beside the fryers and grills. Keep main storage fridges near the delivery entry and prep area, so stock goes in quickly and doors aren't open for long. Make sure the door can open fully without hitting a bench or blocking a walkway, and check which side the hinges are on before you order.

Bars and cafés

Back bar fridges sit under benches, so the front grille and ventilation matter most. Keep drinks fridges close to the service point to save steps on busy nights.

Shops

Put display fridges where customers see them, near the counter for impulse buys, but out of direct sun. Keep open multidecks away from the front door, air-conditioning vents and fans, because draughts disturb the curtain of cold air that keeps them cold.

Floor, power and setup

Level floor. Adjust the feet so the cabinet is level and the doors swing closed on their own. Lock the castors.
Power. Plug straight into a wall power point, not an extension lead or double adaptor. Most of our fridges run on a standard 10 amp plug. Check the product page for anything larger, as some equipment needs a 15 amp outlet.
After delivery or a move. Check the manual for how long to let the fridge stand upright before switching it on, then let it get down to temperature before loading it.
Access. Measure doorways, corridors and corners before you order. Our fridges are delivered by tailgate truck to the front of your premises.

Airflow inside the fridge

Good placement outside is only half the job. Inside, cold air has to move around the food:

Don't block the fan or the air vents with stock.
Leave a gap at the back and between items. Don't pack shelves solid.
In open displays and chest freezers, don't stack above the marked load line.
Restock in batches so the doors aren't open all day.

Placement FAQs

How much space does a commercial fridge need around it?

It depends on the model. The manual lists the clearances for the sides, back and top. Front-breathing underbench fridges can go into joinery with little side clearance, while other models need a gap to release heat.

Can I put a commercial fridge next to an oven?

It's best not to. Heat from the oven makes the fridge work much harder. If there's no other option, leave as much space as possible and choose a fridge with a high room temperature rating.

Can a commercial fridge go outside or in a garage?

Only if the space stays within the fridge's rated room temperature and the fridge is protected from sun and weather. Most commercial fridges are designed for indoor use, so check the manual first.
