Commercial Freezers

The chest freezer behind a frozen-juice window:

it is the workhorse, and for most small businesses the place to start. A solid-lid chest holds its cold best, because cold air sinks and stays put when the lid goes up, and it costs least to run. Many have a key lock, which matters when the freezer sits within reach of the street. The price is manual defrosting and digging for whatever has sunk to the bottom. Glass-lid chests with sliding tops are the shop version, letting customers see the ice cream without the cold pouring out, and some chests switch between freezing and cooling, handy for a kiosk that may move to cold drinks.

Stainless upright freezers in a working kitchen:

an upright earns its floor space where a cook needs a bag of shrimp or a tray of portioned meat without emptying a chest to find it. Most are frost-free, so nobody spends a Sunday chipping ice, but every opening spills cold air onto the floor, and the fan and defrost heater are two more parts to fail. Ice cream parlours use a third kind, the curved-glass dipping cabinet, a specialist machine priced like one. Chilled drinks and dairy belong with commercial refrigerators, ranges and fryers with the rest of the commercial kitchen appliances.

Blackouts, voltage swings and the lid that stays shut:

in Panama they are a better guide to choosing a freezer than any spec sheet. A full chest left closed rides out a long outage with its stock still hard, while a half-empty upright opened by a worried cook starts thawing far sooner, so fill spare space with bottles of frozen water. The surge when power returns is hard on a compressor: plug any freezer, new or used, through a voltage protector that waits before reconnecting, and ask a seller whether theirs ran on one.

Household chest freezers against commercial stainless:

a household chest runs from about $200 for a small one to around $600 for the largest, and for a home business freezing juice bags that is often enough. A one-door stainless upright built for a restaurant is closer to $2,500 new. The extra buys a compressor meant to run all day in a hot room and a cabinet that survives being slammed through every service. Used commercial uprights from kitchens that changed trade turn up around $1,000, and the sealed system decides whether that is a good buy: one never regassed is worth the asking, one that has needed gas twice is not.

Gouges in the liner and rust on the skin:

an empty chest tells its history on the inside. The cooling coils run just behind the inner walls, so anyone who chipped ice off with a knife may have punctured them, and a leak there ends the machine. Look for scratches, dents or a dab of epoxy on the liner. Warm side walls while it runs are normal, since that is where the heat leaves; rust bubbling through the outer skin is not, because the condenser tubing runs right behind it. The lid should stay up on its own and seal all the way round. On a frost-free upright, a back wall caked in ice means the defrost system has failed. And sniff before you commit: a freezer that held fish or bait keeps the smell in its liner, which nobody selling frozen juice can live with.

A freezer handed over defrosted, dry and with its keys:

defrost and dry it before the photos, because a clean liner with no gouges is the picture that sells a chest. Give the capacity and the outside measurements, including the height with the lid open if it has to fit under a counter. Say whether it is manual defrost or frost-free, its voltage, what it stored and whether it ran on a protector, and mention any regassing or compressor work. Keep the lock keys and drain plug with it, tape the lid down, and tell whoever collects it that it travels standing, never on its back.
