40ft Reefer Container with -40°C Cooling Capability

A 40ft reefer container with -40°C cooling capability provides reliable, ultra-low temperature storage for businesses requiring deep-frozen conditions for seafood, pharmaceuticals, or other temperature-sensitive products. For example, this container is perfect for storing tuna, ice cream, frozen meats, or vaccines that must be maintained at -40°C or below . However, unlike standard reefers that typically reach only -20°C to -30°C, this unit features a high-performance refrigeration system capable of achieving -40°C reliably . As a result, you receive a CSC-certified, high cube refrigerated container that maintains consistent deep-frozen temperatures even in ambient conditions up to +50°C . Learn about reefer container specifications from industry guidelines.

Why Choose a -40°C Reefer Container for Your Site?

Standard refrigerated containers typically reach only -20°C to -30°C, insufficient for certain applications. In contrast, this 40ft reefer container with -40°C cooling capability delivers ultra-low temperatures suitable for deep-frozen seafood (Grade A sashimi, tuna), ultra-low temperature pharmaceuticals, and specialised frozen products . Consequently, the 40ft high cube dimensions provide approximately 68 cubic metres of internal capacity with an internal height of 8ft 5in . Moreover, leading refrigeration brands such as Thermo King, Carrier, and Daikin are available, each offering reliable -40°C performance . Thus, you gain professional-grade deep-frozen storage for critical cargo.

Key Features of This -40°C Reefer Container

The ultra-low temperature capability and high cube dimensions are the defining features of this unit. For instance, the temperature range spans from -40°C to +30°C, accommodating deep-frozen goods, chilled produce, and ambient storage . Similarly, the aluminium T-bar floor ensures even cold air distribution throughout the cargo space, with heat leakage values as low as 37.5 kcal/deg.c.hr for optimal thermal efficiency . Furthermore, the unit meets ISO 6346 Type 45R2 certification (45ft high cube reefer equivalent) and complies with CSC, TIR, and classification society standards (ABS, BV, Lloyds Register) . Finally, the MP-4000 controller provides advanced temperature management with precision of +/- 1°C in frozen mode . Check UK storage regulations before ordering.

Thermo King, Carrier & Daikin – -40°C Capable Units

Several refrigeration brands offer -40°C capability on 40ft reefers. For example, Thermo King units are specifically noted for their -40°F to +70°F range (approximately -40°C to +21°C), making them ideal for customers requiring ultra-low temperatures . Likewise, Carrier and Daikin units typically reach -20°C to -30°C, with select models offering -40°C depending on configuration . If you require extreme cooling below -40°C, consider a SuperFreezer unit capable of -65°C to -70°C for specialised pharmaceutical or sashimi-grade seafood applications .

Temperature Performance and Precision

The refrigeration system is designed for demanding frozen applications. For example, the unit maintains -40°C with precision of +/- 1°C in frozen mode, ensuring cargo safety and quality . Likewise, advanced controllers (MP-3000/MP-4000) provide real-time monitoring and data logging capabilities . If you are storing valuable seafood or pharmaceuticals, this temperature precision is essential for product integrity. The unit operates on 3-phase power (360-500V, 50/60Hz) with typical amperage of 25-32A .

Construction and Insulation

Reefer containers are purpose-built for temperature-sensitive cargo. First, walls are filled with CFC-free polyurethane foam insulation (Cyclo Pentane blown, typically 100-120mm thick) with self-extinguishing flammability rating . Second, interior features stainless steel or pre-painted aluminium linings for durability and food-grade compliance . Third, the floor is extruded aluminium T-bar (30mm high) allowing air circulation beneath palletised cargo, with four (4) drain holes at front and rear . Finally, double rear doors feature multi-point locking and rubber seals for weather integrity.

Power Requirements

Proper power supply is critical for -40°C operation. For example, the unit requires 3-phase power (380-460V or 400-500V depending on configuration, 50/60Hz) with 25-32A typical draw . Likewise, a 32A CEE plug is standard for land-based operation . If you lack 3-phase power on site, voltage converters or generators can be arranged. The unit can operate in ambient temperatures from -30°C to +50°C without affecting structural integrity .

What’s Included

First, every unit includes the 40ft high cube reefer container with -40°C capable refrigeration unit (Thermo King, Carrier, or Daikin – subject to availability). Second, CSC safety plate is affixed and valid. Third, aluminium T-bar flooring and multiple air vents are fitted as standard. Finally, lifting points (forklift pockets and crane lugs) are included for repositioning.

For instance, add a temperature data logger for monitoring during storage. Likewise, dual voltage converters are available for 230V/460V operation . Contact our container team for bulk orders.
