40ft Refrigerated Container Dimensions
40ft Refrigerated Container: Specs & Dimensions. Transport temperature-sensitive cargo safely with controlled environment & secure design.
40ft Refrigerated (Reefer) Container Dimensions
The 40ft refrigerated container stands as the industry standard for high-volume, temperature-controlled storage and transport. Often referred to as a reefer, this specialised unit maintains precise internal conditions for sensitive cargo regardless of external weather. A reefer is a refrigerated shipping container designed to maintain the temperature of perishable goods at a constant level. Shipping Containers of Southampton supplies these high-specification units to businesses throughout Hampshire and the surrounding regions, ensuring the integrity of cold chain logistics.
Every unit we supply is built with high-grade insulation and integrated refrigeration machinery. Whether you need to purchase this 40ft reefer unit for permanent inventory or seek flexible hire-a-40 ft reefer container options, our local depot ensures rapid response times. Our units are constructed from stainless steel or aluminium outer skins with food-grade internal linings to meet the highest hygiene standards.
Local Availability and Specialist Stock
We manage a regional inventory specifically designed to serve the Hampshire and M3 corridor. This local presence reduces haulage costs and allows for faster deployment for businesses in Southampton, Portsmouth, and Winchester. Our 40ft reefers are available in both new (single-trip) and used conditions. A one-trip container is a unit manufactured abroad that carries only one cargo load to the UK, ensuring the highest structural and cosmetic quality. For cost-effective solutions, our used reefers undergo rigorous testing of the refrigeration plant and insulation integrity before dispatch.
Before committing to a unit, you should view the complete technical dimension library. This ensures your site can accommodate the substantial 40ft footprint. Unlike standard 40ft shipping container dimensions, reefers have slightly reduced internal dimensions due to the thickness of the insulation panels and the space required for the cooling motor.
Technical Specifications: Internal and External Data
Precise data is essential for planning pallet layouts and site placement. The 40ft reefer provides a significant volume of temperature-controlled space, but the internal aperture must be checked for cargo clearance.

Payload and Cubic Capacity
Loading a 40ft reefer requires an understanding of weight limits to ensure safe handling and legal road transport. You must consider the unit’s tare, payload, and gross weight. Tare is the weight of an empty container. Payload is the maximum weight of goods a unit can safely carry.
- Tare Weight: Approximately 4,500 kg (9,920 lbs).
- Maximum Payload: Approximately 29,500 kg (65,036 lbs).
- Maximum Gross Weight: Approximately 34,000 kg (74,956 lbs).
The 40ft unit is known as a forty-foot equivalent unit (FEU). In a single tier, it can accommodate 20 to 23 standard UK pallets, depending on the specific model and refrigeration unit used. For international transport, every container must have a valid CSC plate. A CSC plate is a safety certificate used for international transport that proves the container is structurally sound and safe for stacking.
Engineering and Power Requirements
Refrigerated containers utilise a sophisticated digital controller to manage the internal environment. These units typically offer a temperature range from -25°C to +25°C. To achieve this, the container requires a constant and reliable power source. Most modern reefers at Shipping Containers of Southampton operate on a 3-phase, 380-460 V, 50/60 Hz supply.
The floor of a reefer is different from that of a standard storage unit. It features an aluminium T-bar floor explicitly designed to facilitate airflow beneath the cargo. This ensures that the temperature remains uniform from front to back in the container. We recommend leaving space at the top of the cargo, known as the “red line” or load line, to allow the fans to circulate air effectively. For farms and local growers, these refrigerated hydroponics units provide a highly controlled growing environment.
Logistics and HIAB Delivery in Hampshire
Navigating the geography of Southampton and the wider South Coast requires specialised equipment. Shipping Containers of Southampton utilises HIAB crane-mounted vehicles to ensure precise placement. A HIAB is a truck-mounted crane used for lifting and positioning containers without needing a separate forklift or on-site crane. Delivering a 40ft unit requires significant space, typically with an articulated vehicle approximately 65ft long.
Before we dispatch a vehicle, we use satellite mapping to assess your site for overhead obstructions. Power cables, low bridges, and overhanging trees can hinder a safe delivery. Live power cables usually require a clearance of at least 20 metres from the vehicle. To ensure your site is accessible, we recommend requesting a delivery assessment through our online form.
Commercial Flexibility: Buy vs Hire
Choosing between purchasing and renting depends on your long-term storage needs and capital budget. Shipping Containers of Southampton provides both options to suit local Hampshire businesses.
| Feature | Purchase 40ft Reefer | Hire 40ft Reefer |
|---|---|---|
| Best For | Permanent chilled facilities | Temporary sites and seasonal peaks |
| Asset Value | Complete ownership and resale potential | Zero capital outlay and no maintenance |
| Customisation | Nearly limitless (paint, shelving) | Standard configuration only |
| Post-Use | You keep or sell the unit | We collect it from your site |
For temporary events or seasonal food surges, container hire is the most flexible option. If you are building a permanent cold-storage facility, our new one-trip reefers offer the longest operational lifespan.
Site Foundation and Maintenance
A stable foundation is critical for the refrigeration unit to operate efficiently. If a container sits on an uneven surface, it can rack. Racking is the slight twisting of the container frame that can cause doors to jam or the refrigeration unit to vibrate excessively. We recommend a level, hard-standing surface such as concrete, tarmac, or compacted gravel.
To prevent moisture from trapping and maintain airflow beneath the unit, we recommend placing the container on railway sleepers or concrete pads at each corner. This is especially important for measuring container footprint. Proper maintenance includes checking door seals regularly to prevent cold air from escaping. If you are in a coastal area such as Portsmouth or Bournemouth, we also recommend rinsing the unit with fresh water to avoid salt corrosion from marine air.
Local Compliance and Planning Permission
Under local authority rules, shipping containers are usually considered temporary structures. However, if the container remains on site for more than 28 days or is located in a Conservation Area, you may need to seek advice. We recommend that all clients check our guide to local council planning rules for their area before finalising a delivery date. This ensures your project stays compliant with local regulations.
What power supply is required for a 40ft refrigerated container?
Most 40ft reefers require a 3-phase, 380-460 V, 50/60 Hz power supply. The unit is typically supplied with a 5-pin 32-amp plug. You should ensure your site has a dedicated isolator switch for safe operation. For technical details, you can speak to our Southampton experts.
Do you offer HIAB delivery in the Southampton area?
Yes, we provide shipping containers for sale in Southampton with full HIAB delivery. This allows us to lift the container over low walls or fences and position it precisely. We use satellite imagery to check for overhead obstructions, such as power lines or low-hanging trees, before dispatching the vehicle.
Is it better to buy or hire a reefer?
Hiring is ideal for short-term projects or seasonal peaks, as it involves no capital outlay, and we handle all maintenance. Buying is more cost-effective for permanent installations and allows for customisation. Many local firms choose to hire a 40ft reefer for temporary stock overflow during peak periods.
Are your used refrigerated containers still food-safe?
Absolutely. Every used unit we supply for sale or hire is thoroughly cleaned and inspected. We ensure the stainless steel or GRP internal lining is intact and that the unit is wind and watertight. We guarantee the refrigeration plant’s performance before it leaves our Southampton depot. You can find out more in our container refurbishment and repair guide.
How do I prevent condensation inside the container?
Refrigerated containers manage humidity through their digital controllers. However, keeping the doors closed as much as possible is essential. For further advice on protecting your cargo, read our guide on buying cargo-worthy containers and proper maintenance.
