Up to -40° F Refrigerated Containers for Sale

Deep-freeze containers down to -40°F

A normal reefer tops out around -10°F, which is fine for most frozen food. But blast-frozen tuna, ice cream, certain vaccines and lab samples have to be held far colder. These units are built for it — heavy-duty refrigeration machines, including Daikin reefers, that pull and hold product all the way down to -40°F. At that range, insulation thickness and machine capacity matter more than anything, which is why these are 40ft purpose-built freezer containers rather than repurposed chillers.

Who needs -40°F cold storage

• Seafood: sushi-grade tuna and sashimi are held at -40°F to lock in quality
• Pharmaceuticals: vaccines and biologics that require ultra-low frozen storage
• Ice cream and frozen desserts: kept hard and stable through transport and holding
• Labs and research: long-term sample and reagent storage
• Blast freezing: rapid pull-down for meat and produce processors

Power and what you get

Deep-freeze units draw more than a standard chiller, so plan on solid three-phase power or a generator sized for the load — the colder the setpoint, the harder the compressor works and the more current it pulls. Sizing your supply (or genset) to the machine is the single most important thing to get right before delivery. Units in this category run $15,000 to $17,650 and arrive tested and certified to hit temperature. Because they're 40ft, you get pallet-rack-friendly floor space alongside the ultra-low capability, so you're not trading capacity for cold.

Why -40°F costs more

The premium over a standard reefer isn't marketing. Holding -40°F means thicker foamed-in insulation, a heavier-duty refrigeration machine and tighter door seals, because every degree colder makes the gap between inside and outside temperature larger and the heat load harder to fight. These are built as freezers from the start rather than chillers pushed to their limit, which is why they hold setpoint reliably under a real load instead of struggling on a hot day. For most frozen food a standard freezer reefer is plenty — reach for -40°F only when the product genuinely demands it, since you'll pay for both the heavier machine and the extra power it draws to run that cold.

If -40°F is more than you need, a standard chiller or freezer from our reefers for sale will cost less. New to reefers entirely?
