40ft Used High Cube Ex Marine Refrigerated Containers
40ft used high cube ex-marine refrigerated containers for sale provide large insulated capacity for active cold storage or non-operational thermal storage. We confirm the exact unit’s machinery status, condition, test evidence, electrical requirements, CSC or ACEP status and delivered price before purchase.
“Ex-marine” describes a reefer’s former shipping-line service; it is not a condition grade or proof of current export suitability. Read our ex-marine refrigerated container guide for the checks that matter.
What Is a Refrigerated (Reefer) Container?
A refrigerated container, or reefer, is an insulated intermodal container with integrated refrigeration machinery. An operational unit can maintain correctly prepared goods within the limits of its exact machinery, ambient conditions, airflow, loading pattern and site power supply.
A reefer is designed to maintain temperature; it should not automatically be treated as a blast freezer. Interior materials, flooring, refrigerant and controller features vary by unit.
- Static chilled or frozen storage
- Seasonal and overflow cold storage
- Temperature-controlled logistics
- Insulated conversion or thermal-storage projects
What Does “Ex-Marine” Mean?
An ex-marine refrigerated container is a reefer retired from active shipping-line or leasing-fleet service. The term describes its service history only; it does not prove age, cosmetic grade, machinery condition, PTI status or current export eligibility.
Dents, repairs, shipping-line markings and cosmetic wear are normal. Buyers should assess the exact container, machinery evidence and intended use rather than relying on the “ex-marine” label alone.
Why Choose a 40ft High Cube Reefer?
A 40ft high cube reefer provides more internal height than a standard-height 40ft container and substantial capacity for palletised or bulky stock.
- Additional headroom for loading and airflow planning
- Large volume for bulk cold storage
- Potentially better cost per cubic metre than multiple smaller units
- Useful insulated shell for suitable conversion projects
The right choice still depends on stock layout, door-opening frequency, access, power and required temperature duty.
Two Types of 40ft Used High Cube Reefers Available
Used Operational Reefer
An operational unit is offered with refrigeration machinery intended to run. Before purchase, confirm the exact inspection or PTI date, test scope, controller and alarm status, known repairs, refrigerant, electrical requirements and any warranty terms.
A machinery test does not guarantee future performance. CSC or ACEP status is a separate structural shipping matter and must be checked independently if export use is planned.
Typical uses: static chilled or frozen storage, food and drink stock, agricultural produce and other commercial cold-storage duties where the complete installation is suitable.
Used Non-Operational Reefer
A non-operational reefer is sold without relying on its refrigeration machinery. It can provide an insulated shell for dry storage or conversion, but insulation, doors, drainage, floor and structural condition must be assessed on the exact unit rather than assumed.
Typical uses: temperature-buffered dry storage, workshops, specialist conversions and other projects where active cooling is not required.
Temperature Control & Performance (Operational Units)
Temperature capability is exact-unit dependent. Machinery model, refrigerant, age, ambient temperature, product load, airflow, door openings and site power all affect performance.
Do not buy on a generic setpoint range alone. Confirm the required operating temperature, the machinery specification and suitable test evidence for the actual container. A controller setting is not proof that a loaded container will achieve the same temperature in every condition.
Construction & Materials (Marine Spec)
Construction varies by manufacturer and year, but a 40ft ex-marine high cube reefer will normally combine an insulated shell, hygienic internal lining and an airflow floor.
- Steel or aluminium external components
- Stainless-steel or aluminium internal lining, depending on unit
- Insulated wall, roof and door panels
- Aluminium T-bar or comparable airflow flooring
Confirm the exact materials, repairs, floor condition and door-seal condition before purchase.
Shipping Certification & Testing
CSC or ACEP and PTI answer different questions.
- CSC or ACEP: concerns structural safety for international transport and must be current and acceptable for the intended route.
- PTI or machinery test: is a point-in-time check of the refrigeration equipment and does not guarantee future performance.
Neither should be implied from the words “ex-marine”. Ask what evidence is supplied with the exact unit. Our marine-spec reefer guide explains this distinction in full.
Standard 40ft High Cube Reefer Specifications
Approximate external dimensions: 40ft long × 8ft wide × 9ft 6in high.
Condition: used / ex-marine. Internal dimensions, weight, machinery, refrigerant, electrical demand and materials vary by unit.
Power must be taken from the machinery data plate and confirmed by a competent electrician. Do not assume every 40ft reefer uses the same socket, current rating or protective device.
Typical Uses for 40ft High Cube Refrigerated Containers
40ft operational reefers are commonly considered for food and beverage stock, seafood, agriculture, catering, wholesale and seasonal overflow storage.
For pharmaceutical, medical or other regulated goods, the container alone is not enough. The complete storage system, monitoring, alarms, calibration, procedures and site installation must be qualified or validated for the intended use.
Door-opening frequency, product pull-down requirements and airflow should be reviewed before treating a reefer as an alternative to a fixed cold room.
Condition & What to Expect
Used reefers are purchased for practical capacity, insulation and,where applicable,machinery performance, not a new cosmetic finish.
Expect dents, scratches, repairs, shipping livery and wear consistent with previous marine use. Ask for the actual unit’s condition, machinery evidence and photographs where available. Any functional assessment should state what was checked and when.
Optional Extras & Conversions
Options depend on the exact unit and intended project, and may include:
- Internal lighting
- Person-trapped alarm or emergency-release provisions where required
- Strip curtains
- Floor or access modifications
- Repainting
- Bespoke conversion work
Requirements should follow the site risk assessment and applicable rules. Explore our shipping container conversion service.
Delivery & Power Considerations
A 40ft reefer needs suitable large-vehicle access, adequate manoeuvring and offloading space, firm level ground and clearance around the machinery end for airflow and servicing.
Operational units also need the exact electrical supply specified on the machinery data plate. Confirm the delivery method, access and power before ordering. Read our container delivery access guide.
Commissioning After Delivery
A 40ft used high cube refrigerated container should be commissioned after delivery before stock depends on it.
Commissioning should confirm the electrical connection, controller operation, alarms, setpoint, airflow, drainage and whether the empty unit reaches and holds the required temperature under the agreed test conditions. Loaded performance will also depend on the goods, loading pattern, ambient conditions and door use.
Use a suitably qualified engineer where the machinery, warranty, site rules or intended goods require one. Record the settings and test results for future reference.
Why Buy a 40ft Reefer from Bosh Boxes?
- Clear distinction between operational and non-operational units
- Exact-unit condition and machinery evidence explained before purchase
- PTI kept separate from CSC or ACEP status
- Electrical and delivery requirements confirmed rather than assumed
- UK-wide delivered-price quotations
We focus on matching the reefer to the intended duty, site and evidence required,not overselling a generic specification.
Bottom Line
A 40ft used high cube ex-marine refrigerated container can offer excellent large-capacity cold storage, but the right unit depends on its actual machinery, test evidence, condition, power requirements, site access and intended duty.
If 40ft is too large, compare our 20ft used ex-marine refrigerated containers. For the correct unit and a clear delivered price, request your refrigerated container quote.
