The Cubner Blast Freezer 40-foot container is a mobile, ultra-rapid freezing unit. It reaches extreme temperatures ranging from +30°C to -70°C. Designed for the most demanding industries, this converted shipping container completely halts the biological degradation process of products. In fact, it guarantees optimal preservation of organoleptic and sanitary properties.

Why choose the Blast Reefer Cubner?

The Blast Reefer Cubner differs from conventional refrigerated containers in three key ways.

First, its cooling speed is unparalleled. Unlike a conventional reefer container equipped with a single refrigeration unit, the Blast Freezer incorporates five refrigeration units. This allows it to reduce the core temperature in record time. Furthermore, its cooling capacity is five times greater than that of a standard container.

Secondly, its Corten steel structure offers mobility and robustness. You can use it for dock-height storage. It can also be transported by flatbed truck or container ship.

Thirdly, it complies with HACCP standards. Therefore, it is perfectly suited for storing seafood, premium meats, or sensitive electronic components.

Standard container vs Blast Reefer: which is the right choice?

A standard reefer container maintains a constant temperature for already chilled products. The Blast Reefer, on the other hand, has significantly greater refrigeration capacity. It rapidly extracts heat from the products and can reach temperatures as low as -70°C, depending on the refrigeration unit installed.

In terms of figures, the difference is significant. A standard container generates 11,99 kW at +1,7°C and 5,04 kW at -29°C. The Blast Reefer, on the other hand, generates 59,95 kW at +1,7°C and 25,20 kW at -29°C. The power output is therefore five times greater.

Reliability and redundancy: zero risk of breaking the cold chain

One of the major advantages of the Blast Reefer container lies in its redundancy. If one of the five units fails, the other four remain operational. The risk of a total loss of the cold chain is therefore virtually nil. Furthermore, temperature recovery after the door is opened is very rapid.

In comparison, a standard container has no redundancy. In the event of a failure, the risk of total loss is high. Recovery after a door opening is also slow.

Optimal operation and thermal homogeneity

The Blast Reefer container offers excellent thermal uniformity thanks to its multiple diffusion points. Furthermore, its regulation is adjustable: you can operate it in partial mode as needed. This allows for very rapid temperature reduction.

Conversely, a standard container exhibits average thermal homogeneity. Its temperature regulation flexibility also remains limited.

Power supply: what you need to plan for

To achieve such performance, the Blast Reefer requires a three-phase power supply (400V/50Hz). Each refrigeration unit has its own separate power supply. The total power can reach 60 kW, which is why we recommend working with a specialist company. See our detailed information for more details. guide to refrigeration units.

Independent management of the five refrigeration units

Each refrigeration unit operates independently with its own control panel (controller). For optimal performance, it is best to set the same target temperature on all units. This configuration ensures both accuracy and safety.

An interior space dedicated to a single temperature zone

The Blast Reefer container manages a single temperature zone. In fact, the entire interior space is designed to maintain maximum uniformity. This configuration ensures consistent freezing of your entire shipment.

Which container should I choose for freezing down to -70°C?

For ultra-low temperatures, the Cubner 40-foot Blast Freezer container is the ideal solution. It surpasses the capabilities of a standard reefer container thanks to its industrial-grade refrigeration power.

Points to consider before purchase

The power ratings shown are based on the Thermo King Magnum Plus chiller unit, used here as a reference. A five-unit configuration results in a longer acquisition time. It also requires a reinforced power supply and sufficient installation capacity. Furthermore, maintenance is multiplied by five. The theoretical sum of the power ratings assumes ideal conditions; therefore, a preliminary technical study is essential.
