Why kitchen heat changes everything
A refrigerator moves heat from inside the cabinet to the room through its condenser. The condenser can only reject heat if it is hotter than the air around it, so as the kitchen warms, the whole system has to run hotter and harder. Capacity falls, run times lengthen and the compressor runs closer to its limits. A unit sized for a 32 °C room may hold temperature at night but lose it during lunch service, exactly when doors open most.
Ask every supplier for the ambient temperature at which the cabinet holds its rated band, and how long it takes to recover after the door has been open. For household appliances the 'T' (tropical) climate class covers rooms up to 43 °C; commercial cabinets are rated differently, so ask for the rated ambient as a number.
Match the cabinet to the room
| Condition | What happens | What to ask for |
|---|---|---|
| Air-conditioned prep room | Easy duty; long compressor rest periods | Standard cabinet; focus on capacity and layout |
| Cooking line near fryers or tandoor (38–43 °C+) | Long run times, slow recovery | High rated ambient, generous condenser, fan-assisted cooling |
| Humid coastal city | Door sweating, faster frost on the coil | Good gaskets, anti-condensation measures, automatic defrost |
| Flour or grease in the air | Condenser clogs within weeks | Easy access to the condenser for cleaning; filter if offered |
Doors and sizes
Reach-ins come as one-door, two-door and sometimes three-door cabinets, and many offer half doors. Half doors halve the cold air lost each time someone grabs a single item, which helps a lot in a hot kitchen. Solid doors insulate far better than glass; choose glass only if staff genuinely need to see stock without opening up, as in a bar or a front-facing kitchen.
- Self-closing doors with a hold-open position for loading.
- Reversible hinges, so the door opens away from the walkway.
- A lock if stock control matters.
- Front clearance for the door to swing fully — measure it, including the open-door depth.
Shelving that fits your containers
Litre ratings are gross volume and say little about how much fits. Check whether the interior takes GN 2/1 shelves (650 × 530 mm) so full-size gastronorm pans and trays slide straight in, and how many shelf positions are available. Bakeries may want slides for 600 × 400 mm trays instead. Plastic-coated or stainless wire shelves let air circulate; solid shelves block it.
Keep the bottom shelf high enough to clean under and leave space between stock and the evaporator fan, because a cabinet packed tight cools unevenly.
Top- or bottom-mounted refrigeration unit
Top-mounted units keep the condenser away from floor dust and mopping water, but they breathe the hottest air in the kitchen, which gathers near the ceiling. Bottom-mounted units breathe cooler air and are easy to reach for cleaning, but pick up grease and flour from the floor and can be splashed during wash-down. In a very hot, high-ceilinged kitchen a bottom-mounted unit usually has the edge; in a wet kitchen with low ceilings the choice is closer.
Cooling, defrost and drainage
- Fan-assisted (ventilated) cooling recovers temperature faster and evens it out between shelves.
- Automatic defrost prevents ice choking the evaporator; ask how often it runs and whether it can be timed outside service.
- Ask where defrost water goes. Units that evaporate it themselves need no floor drain.
- Ask whether coils and internal fittings are protected against corrosion from salty or acidic foods.
Build details that decide its lifespan
A reach-in in a busy kitchen is opened, slammed, leaned on and washed down every day. The body and door construction decide whether it still seals properly in its fifth year. Polyurethane foam (PUF) insulation is standard; thicker walls cut heat gain and running cost, which matters more the hotter the room. Stainless steel inside and out is easiest to keep hygienic, and the grade matters in kitchens that handle brine, tamarind, lime and harsh cleaners — ask which grade is used on the interior liner, not just the door skin.
- Door hinges and closers rated for constant use; sagging doors are the commonest cause of poor sealing.
- Magnetic gaskets that push in and pull out for cleaning and replacement.
- Adjustable feet or castors with brakes, so the cabinet can stand level on an uneven floor.
Controls and power
A digital controller with a large display lets staff read the temperature without opening the door. High-temperature and door-open alarms catch problems before stock is lost. On Indian supply — nominally 230 V single-phase at 50 Hz, with sags and spikes — ask for the unit's operating voltage range, whether a stabiliser is recommended, and whether the controller delays compressor restart after a power cut. Give each reach-in its own earthed socket.
Frequently asked questions
- Should I buy a bigger reach-in so it is never full?
- Size for your busiest day plus room for air to circulate, not much more. An oversized cabinet costs more to run and tempts staff to keep stock longer than they should.
- Can a reach-in be installed right next to a range?
- Avoid it if you can. Every degree of extra air temperature at the condenser costs capacity. If there is no choice, leave the clearance the manufacturer specifies and clean the condenser more often.
