1. Start with what you store, not with the cabinet
Every choice that follows depends on the temperature band your product needs. Write down what will live in the unit and how often staff will reach for it during service.
| Band | Typical range | Common uses |
|---|---|---|
| Chilled | +2 °C to +8 °C | Dairy, cut vegetables, marinated meat, prepared sauces, cooked food held for service |
| Beverage / display | +2 °C to +10 °C | Bottled drinks, packaged dairy, desserts on show |
| Frozen | −18 °C or colder | Frozen meat and seafood, ice cream, frozen snacks |
| Low / ultra-low | −25 °C to −60 °C and below | Specialist storage such as some pharma, lab and long-hold seafood applications |
2. Plan for the heat around the unit
Refrigeration works by moving heat out of the cabinet and dumping it into the room. The hotter the room, the harder the compressor works — and the room next to a tandoor, fryer or combi oven can run far hotter than the city's weather report suggests.
Ask every supplier what ambient temperature the unit is designed to hold its rated temperature at. For household fridges this is expressed as a climate class, where 'T' (tropical) covers rooms up to 43 °C; for commercial cabinets ask for the rated ambient directly. A unit rated only for a 32 °C room will struggle in a 40 °C kitchen.
- Keep the condenser away from fryers, ovens and dishwasher exhaust.
- Leave the clearance the manufacturer specifies at the back and top for airflow.
- Avoid direct sunlight on glass-door units near shop fronts.
3. Check the power supply you actually have
India's nominal supply is 230 V single-phase at 50 Hz, but many kitchens and markets see sags in summer evenings and spikes when heavy equipment switches. Compressors are the component most damaged by poor voltage.
- Ask for the unit's operating voltage range and whether it needs a stabiliser.
- Give each large unit its own properly earthed socket rather than an extension board.
- If your site has frequent outages, ask how the controller behaves on restart (delay timers protect the compressor).
4. Size it by what fits, not by the litre number
Brochure capacity is usually gross volume. Shelves, the evaporator and air gaps take space, so usable storage is lower. Bring a list of the containers you use — crates, bottles, trays or GN pans (a GN 1/1 pan is 530 × 325 mm) — and ask how many fit per shelf.
Size for your busiest day, not your average one, and leave room for air to circulate: a packed cabinet cools unevenly.
5. Choose the format that matches the workflow
Upright reach-in cabinets give the most storage per square foot of floor. Undercounter units put chilled ingredients at the point of use and double as a worktop. Glass-door visi coolers and display cases sell product as well as store it. Chest deep freezers hold cold well because cold air stays in when the lid opens.
6. Look closely at the build
- Stainless steel: grade 304 resists corrosion from salt, acids and cleaning chemicals better than lower-nickel grades such as 202 or 430. Ask which grade is used inside and outside.
- Insulation: polyurethane foam (PUF) is standard; thicker walls hold temperature better and cut running cost.
- Cooling type: fan-assisted (ventilated) cooling recovers faster after door openings and holds a more even temperature than static cooling.
- Defrost: automatic defrost saves labour; ask where the defrost water goes and how the drain is cleaned.
- Doors and gaskets: self-closing doors and replaceable magnetic gaskets matter more than they look.
- Controller: a digital controller with a visible temperature display and high-temperature alarm makes problems obvious before stock is lost.
7. Ask which refrigerant it uses
Many newer units use hydrocarbon refrigerants such as R290 (propane) or R600a (isobutane), which have a very low global-warming potential. Older HFCs such as R134a have a far higher one, and India has ratified the Kigali Amendment to phase down HFCs over the coming decades. Hydrocarbon units need technicians trained to handle flammable refrigerants — another reason to check who will service the unit.
8. Buy the service network, not just the box
A refrigerator that fails on a Saturday night costs the stock inside it. Before price, ask who repairs the unit in your city, how fast, and where spares come from.
- What does the warranty cover — whole unit, compressor, labour, travel?
- Is there an annual maintenance contract (AMC), and what does a visit include?
- Are spares such as gaskets, fans and controllers stocked locally?
- Who installs and commissions the unit, and is that included?
9. Compare running cost, not just purchase price
Ask for the rated energy use in kWh per day and the ambient temperature it was measured at, so you compare like with like. For chest-type deep freezers, the Bureau of Energy Efficiency (BEE) runs a star-labelling programme — ask whether the model you're offered carries a BEE label and what its rated annual consumption is.
Questions to ask every supplier
- What temperature does it hold, at what room temperature?
- What voltage range does it run on? Do I need a stabiliser?
- How many of my containers fit per shelf?
- Which stainless steel grade, inside and out? How thick is the insulation?
- Which refrigerant? Who in my city is trained to service it?
- What does the warranty cover, and what does an AMC cost and include?
- What is the rated energy use per day?
Frequently asked questions
- Can I use a domestic refrigerator in a restaurant kitchen?
- It will work for a while, but domestic units are built for a few door openings a day in a cooler room. In a commercial kitchen they struggle to recover temperature after frequent openings, and their compressors, hinges and gaskets wear quickly.
- How much clearance does a commercial refrigerator need?
- Follow the manufacturer's figure for the specific model. Units that exhaust heat through the back or top need open space there; units with front-breathing condensers can sit closer to walls and under counters.
