Commercial Under Bench Fridge Buying Guide: Doors, Glass and Airflow
Walk any busy line in Australia and the under bench fridge is doing more work than it gets credit for: it is the cold storage for the proteins, dairy and mise en place a chef reaches for dozens of times an hour, and its top is the prep bench they work on. Choosing the right commercial under bench fridge comes down to five things: door count and usable storage, solid or glass door, how the unit breathes, the ambient rating, and the working details such as castors, GN pan fit and the controller.
This guide sizes each decision to the bench run and the service. Browse the current range of commercial under bench fridges at Commercial Kitchen Appliances.
If you are already comparing two FED-X models, our FED-X XURC vs XURF undercounter guide goes model by model. This article stays brand-neutral and covers the questions that apply to every undercounter fridge.
Door count: 1, 2, 3 or 4 door under bench fridges and usable storage
Door count follows width. In the current range, single door workbench fridges start at around 900 mm wide, two door (double door) models run from roughly 900 mm to 1500 mm, 3 door units sit around 1368 mm to 1800 mm, and 4 door cooling tables stretch past 2 metres. Measure the bench run first, allow for door swing and any adjacent equipment, then pick the largest door count that fits.
More doors is not only more litres. Each door is a separate section, so staff open one compartment while the others stay shut. That limits cold loss through service and lets you zone stock by station: proteins behind one door, dairy and sauces behind another, prepped vegetables behind the third.
Gross vs net capacity
Always compare net (usable) litres, not gross. Gross volume is the inside of the cabinet; net is what you can actually load once shelves, evaporator and airflow space are accounted for. The gap is significant. One 3 door model in our range lists 339 L gross but 254 L net, and a compact two door unit lists 205 L gross against 161 L net.
| Door count | Typical width in range | Example capacity | Best suited to |
|---|---|---|---|
| 1 door | around 900 mm | 100 L | Coffee stations, small bars, a single prep corner |
| 2 door | 900 to 1500 mm | 160 L to 278 L | Cafes, sandwich bars, a single cook-line station |
| 3 door | 1368 to 1800 mm | 251 L to 350 L | Restaurant lines, under a pass, busy takeaway |
| 4 door | up to about 2230 mm | 339 L to 560 L | Large kitchens, hotels, catering production |
Depth matters as much as width. Most units in the range are either 600 mm or 700 mm deep. A 600 mm body is the space-saving choice for narrow galley lines and standard bench depths; a 700 mm body takes more stock per door and handles full-size GN pans more comfortably. If you need frozen storage in the same footprint, compare the matching under bench freezers, which share similar widths so a fridge and freezer can sit side by side under one continuous bench.
Solid door vs glass door under bench fridges
A solid door is the default for back-of-house. Insulated stainless doors hold temperature better than glass, recover faster after opening, cost less to run and survive knocks from trolleys and boots. If the fridge sits under a prep bench and only staff see inside it, solid door is almost always the right call.
A glass door earns its place where visibility matters. Staff can see stock at a glance and grab it without holding the door open to search, which cuts door-open time on a fast line. Front-of-house, a glass-fronted unit merchandises product to customers at a counter. The trade-off is heat gain through the glass, so look for double-glazed or well-sealed doors and a strong ambient rating if the unit faces a warm service area. Compare options in the undercounter glass door fridge range.
Under bench fridge vs bar fridge vs prep fridge
They look similar from the front, but each is built for a different job, and mixing them up is a common fit-out mistake.
| Feature | Under bench storage fridge | Bar fridge | Pizza or salad prep fridge |
|---|---|---|---|
| Main job | Chilled food storage under a work surface | Chilling and displaying drinks | Holding toppings in pans at the build point |
| Typical doors | Solid stainless, hinged | Glass, hinged or sliding, often lockable | Solid doors below, chilled pan well on top |
| Typical range | -2 to 8°C | +2 to +8°C | +2 to +8°C or -2 to 8°C |
| Top surface | Stainless work bench | Sits under a bar counter | GN pan rail with lid, canopy or cutting board |
| Where it sits | Back-of-house prep and cook lines | Behind the bar, front counter | Pizza bench, sandwich and salad line |
A bar fridge is designed around bottles and cans. Glass doors, interior lighting and a front finish that suits a customer-facing bar are the priorities, and sliding doors are available where nothing can swing into the walkway behind the counter. Use a bar fridge for beverages; do not rely on one as your main food storage. See the commercial bar fridges range for glass door bar coolers.
A prep fridge adds a refrigerated pan well on top so ingredients are chilled right where orders are assembled. Pizza prep fridges and salad bar fridges suit pizzerias, sandwich bars and salad counters. Our salad bar vs pizza prep fridge guide covers that choice in detail. If you only need storage and a bench top, a standard storage unit is simpler and holds more below the bench.
Ventilation: front-breathing vs rear-breathing
Every refrigerated cabinet moves heat out and dumps it through the condenser. Where that hot air goes decides where the unit can be installed, and it is the detail most often missed when a unit is built into joinery.
Front-breathing units
A front-breathing unit draws cool air in and exhausts warm air through a grille at the front. Because it does not rely on space behind it, it can sit flush against a wall or inside a bench cavity, provided the front grille is never blocked by bins, boxes or kick panels. For a built-in under-bench install, this is the configuration to specify.
Rear-breathing units
A rear-breathing unit exhausts through the back or sides and needs clear air space around it. Box one into a cabinet and it recirculates its own hot air: the compressor runs longer, running cost climbs, the cabinet struggles to hold temperature in summer and component life shortens. Freestanding placement with the manufacturer's clearances works well.
Whichever type you choose, check the manufacturer's installation clearances before the joiner builds the bench, and keep the condenser clean so the unit stays energy efficient. Our guide to energy saving tips for commercial refrigeration explains how a dusty condenser quietly lifts power use.
Ambient and climate rating for hot Australian kitchens
The ambient rating is the room temperature it is designed to hold its cabinet temperature in. It is one of the most important specs for Australian conditions and one of the least read. The room may be 25°C at the door and well over 35°C beside the fryers on a summer service.
Ratings in our current range run from around 30°C to 43°C. As a general guide:
- Around 30 to 32°C: suits air-conditioned cafes, bars and cooler prep areas.
- Around 38°C: a middle ground for warm service areas and front counters.
- Tropical-rated to 43°C: the choice for cook lines next to heat-producing equipment, kitchens without air-conditioning and hot regional sites.
Measure or estimate the temperature where the unit will actually sit, not the room average. A cabinet running above its rated ambient will work continuously, struggle to recover after door openings and can drift above safe holding temperature through a long service.
Castors vs legs, GN compatibility and digital controllers
Castors or adjustable legs
Castors let you roll the unit out to clean underneath and behind it, which matters for pest control and council inspections, and make it easy to reconfigure a line. Several workbench fridges in the range ship on castors. Adjustable legs suit fixed installs where the fridge must sit level with adjoining benches and stay put. On castors, lock the front wheels during service.
GN pan compatibility
If your kitchen works in gastronorm pans, check that the cabinet is GN1/1 compatible. A GN-compatible fridge takes full-size pans on shelves or runners, so prepped ingredients go straight from prep to storage to the line in the same pan. Several compact models in the range are GN1/1 compatible, and 700 mm-deep cabinets generally handle GN pans more comfortably than shallow ones.
Digital controllers and temperature control
A digital controller gives precise temperature control and a readable display, so staff can check the cabinet at a glance during service. Look for clear set-point adjustment, auto defrost and, ideally, alarms. Auto defrost with a self-evaporating drain removes manual defrost downtime and the drip tray to empty. The display is a guide, not a record, so still verify with a probe thermometer.
Food safety: holding at 5°C or below
Under the FSANZ Food Standards Code, Standard 3.2.2 (Food Safety Practices) requires potentially hazardous food to be kept under temperature control, which general Australian guidance sets at 5°C or below for cold food. Standard 3.2.3 (Food Premises and Equipment) covers the equipment itself, including easy-to-clean surfaces. See Food Standards Australia New Zealand for the current wording, and confirm local council and state requirements for your premises.
In practice that means choosing a unit with enough capacity and ambient headroom to hold product under 5°C through the busiest part of service, not just first thing in the morning. Set the controller comfortably below the limit, avoid overloading shelves so air can circulate, keep door openings short and log temperatures.

Ready to choose your under bench fridge?
Start with the bench run and the service. Measure width and depth, pick the door count that fits and compare net litres, not gross. Choose solid doors for back-of-house and glass where staff or customers pick by sight. Specify front-breathing if the unit is built in, and match the ambient rating to the hottest spot it will sit in. Then check castors or legs, GN pan fit and a digital controller that makes holding at 5°C or below easy to verify.
If the job is drinks, look at a bar fridge; if it is building orders from chilled pans, look at a prep fridge. For everything else, compare the full range of commercial under bench fridges.
Frequently asked questions
Which is the best undercounter fridge for a commercial kitchen?
There is no single best model. The right unit is the one whose width fits the bench run, whose net capacity covers a full service, and whose ambient rating matches the hottest spot it will sit in. For a hot cook line, shortlist fan-forced units rated to 43°C ambient with a digital controller. For a front bar, a glass-fronted bar fridge usually suits better. Match the unit to the job before comparing brands.
What is the difference between an under bench fridge and a bar fridge?
A commercial storage fridge is back-of-house storage: usually solid stainless doors, a -2 to 8°C range and a work surface on top for prep. A bar fridge is built to display and chill drinks, usually with glass doors, interior lighting and a +2 to +8°C range, and often a black or stainless front for customer-facing positions. Use the storage fridge for food and the bar fridge for bottles and cans.
Do under bench fridges need ventilation when built into joinery?
Yes. Every fridge has to reject heat from its condenser. A front-breathing unit draws and exhausts air through the front grille, so it can sit inside joinery or against a wall as long as the grille stays clear. A rear-breathing unit needs open space behind and around it. Boxing a rear-breathing fridge into a cabinet traps heat, raises running costs and shortens compressor life. Check the manufacturer's clearance requirements before building in.
What ambient rating should a commercial undercounter fridge have in Australia?
Match the rating to the real temperature at the installation point, not the room average. Units in the current range are rated from about 30°C up to 43°C ambient. A 30 to 32°C rating can suit an air-conditioned cafe or bar. Next to fryers, a combi or a chargrill, or on a line without air-conditioning, a tropical-rated unit specified to 43°C gives far more headroom through a hot summer service.
What temperature should a commercial under bench fridge run at?
Under Australian food safety guidance, potentially hazardous food should be held at 5°C or below. Most commercial storage fridges run a -2 to 8°C range, so set the controller to hold product comfortably under 5°C and check it with a calibrated probe thermometer, not just the display. Log readings as part of your food safety program and confirm any extra requirements with your local council or state food authority.
