If you are searching for “reefer container for sale”, chances are you need to move or hold temperature-sensitive goods at scale: produce, dairy, frozen food, pharmaceuticals, flowers, or a permanent cold room for a business. A 40ft high cube reefer is the biggest standard refrigerated box on the market, and it is also the one where buying the wrong version costs the most. The main decision is simple: a working unit that actually refrigerates, or a non-working insulated shell. This guide explains the difference, who each suits, what power you need, and how to buy without surprises.
Quick answer: choose the 40ft high cube working refrigerated container if you need cold storage now, and the 40ft high cube non-working refrigerated container if you want a heavily insulated shell for storage, a conversion, or your own refrigeration build.
What is a 40ft high cube reefer?
A reefer is an insulated container with a built-in refrigeration unit mounted at the front. “High cube” means the box is one foot taller than a standard container, which adds interior height and cargo volume. The insulated walls, floor and ceiling hold the temperature the refrigeration unit sets. Compared with a regular dry container, a reefer has a lot more going on: thick insulation, a floor designed for air circulation, and a machine that needs power.
Working vs non-working: which should you buy?
| Working reefer | Non-working reefer | |
|---|---|---|
| Refrigeration unit | Working, function-tested | Removed or non-functional |
| Best for | Cold storage, cold-chain transport, on-site cold room | Insulated storage, conversions, custom builds |
| Needs power | Yes, for the unit | No, unless you add your own equipment |
| Upfront cost | Higher | Lower |
| Main risk | Power supply and running cost | Cooling must be added; cannot hold temperature as sold |
Who buys a 40ft high cube working reefer?
- Food businesses: restaurants, caterers, butchers, farm stands and distributors that need walk-in capacity.
- Growers and farms: short-term cold storage at harvest.
- Events and seasonal retail: temporary cold rooms for holiday peaks.
- Exporters: cold-chain shipments where the box is part of the product.
Who buys a non-working reefer?
- Buyers who want thick, insulated walls for a quieter, more stable storage space and do not need active refrigeration.
- Builders converting a container into a studio, workshop or utility room who want an insulated shell.
- Operators who plan to install their own refrigeration or cooling equipment.
Be clear with yourself about this: a non-working reefer is not a cold room as sold. If you need to keep goods cold, buy the working version or budget for adding refrigeration.

Power and site requirements
Reefer units run on electrical power, and reefer power is not the same as an ordinary household outlet. Typical refrigeration units use three-phase power, so check the exact voltage and plug type for the unit you buy and confirm it with us before delivery. Beyond power, plan for:
- A level, firm surface. See the site preparation guide.
- Airflow around the machine end. Do not box in the refrigeration unit.
- Delivery access. A 40ft box needs room for a truck to turn and place it. Read the delivery process guide.
- Permits. Some areas regulate temporary or permanent structures. See the zoning and permits guide.
What to check before you buy a used reefer
- Unit status: confirm whether the refrigeration unit is working and how it was tested.
- Box condition: inspect door seals, floor, interior panels and exterior dents.
- Temperature range: ask what the unit is rated for, and match it to your goods.
- Power: voltage, phase and plug type.
- Documentation: ask for photos, grade and any inspection paperwork.

How much does a 40ft high cube reefer cost?
Price depends on whether the unit works, the age and the condition. Request a quote on the product page for current availability and delivery to your location.
Can I use a non-working reefer as a freezer?
Not as sold. It is an insulated shell. You would need to add a refrigeration system.
Do you deliver reefers?
We deliver nationwide in the U.S., and international export is available. Ask for a delivered quote.
What is the difference between a reefer and a climate controlled container?
A reefer is built for cold-chain temperatures. A climate controlled storage unit keeps a comfortable range for sensitive items. See our climate controlled containers guide.
