Countertop display chillers: choosing a small refrigerated showcase

Main countertop case styles

Always check that the case can hold the food-safety temperature your product needs. Open-front cases struggle to keep product at or below 5 °C in a warm shop and suit packaged items with short display times.

Glass, light and heat load

A display case is mostly glass, and glass lets heat in far more easily than an insulated wall. Add lighting, a sunny window and a counter next to an espresso machine, and the case is fighting hard. Double glazing reduces heat gain and condensation; LED lighting adds much less heat than older lamps.

Ask what ambient temperature the case is rated for and test it, if you can, in conditions like yours. A case rated only for a cool, air-conditioned mall will fog up and run warm in a non-AC bakery in May.

Humidity: cakes and sushi want different things

• Cream cakes and mousse dry and crust in a fan-forced case with very dry air. Cases designed for pastry often use gentler airflow or humidity control.
• Sushi rice hardens when chilled and dried; sushi cases typically use a cold base plate and a closed hood rather than strong fans.
• Bottled drinks do not care about humidity; a fan-assisted glass-door cooler is ideal.
• Wrapped products tolerate drier air than unwrapped ones.

Customer side or staff side

Decide who opens the case. Self-service cases have doors on the customer side and need hinges and handles that survive constant use. Serve-over cases open at the back for staff, which protects food from handling and keeps hygiene under control. Many bakeries prefer rear sliding doors for cream cakes so only staff touch the product.

Placement on the counter

• Check where the case breathes: many countertop units take air in and out at the sides or rear, so do not wedge them between other machines.
• Keep the case away from coffee machines, fryers, ovens and direct sun.
• Make sure the counter can take the weight of a loaded case and is level, so doors close and the drain works.
• Give the case its own socket; small compressors are just as sensitive to voltage sags as large ones.
• Leave space to reach the controller and the condenser for cleaning.

Sizing a countertop case

Measure the counter before you look at brochures. Note the depth available, the height under any shelves or menu boards above and the space you need to keep for the till, the card machine and the customer's elbows. A case that blocks the line of sight to staff or forces customers to lean across it costs sales.

Then count what must be on show at the busiest hour: the number of cake slices, sushi plates or bottles that make the case look full. A half-empty case looks like the end of the day; an overloaded one blocks airflow and runs warm. Many outlets do better with a slightly smaller case restocked from a back refrigerator than with one large case packed to the glass.

Daily practice that keeps product safe

Load the case with product that is already cold; a display case holds temperature but cools warm food slowly. Do not block the air return at the front or back with trays or price cards. Move product back to storage refrigeration at closing if the case is switched off at night, and clean the glass and base daily. A probe thermometer check at opening and mid-afternoon catches drift before it becomes a food-safety problem.
