  • Ultra-low temperatures down to -70°C for the most sensitive and valuable cargo
  • Based on Thermo King SuperFreezer unit with cascade technology and double thickness insulation for the best performances in low temperatures
  • Advanced temperature management control system for extremely precise temperature control +/- 1°C over the whole operating range
  • Available in sizes 10 / 20 ft

Extreme performances for the most sensitive products

Trane SuperFreezer goes way beyond any conventional controlled temperature storage, to unveil new opportunities coming from lower temperature setpoints.

Food products like meat and seafood maintain all qualities of fresh food. Yoghurt or probiotics cultures can be preserved for extended periods, all microbial activity being blocked.

In the same way, SuperFreezer offers a reliable and compact solution for pharmaceutical or biological material storage, such as mRNA vaccins or blood related products.

Precise temperature control

The unique Superfreezer is designed for ultra-low high valuable products typically stored for longer duration.

Reliability, performance and advanced temperature control is a must have. With the MP3000 control system you get precise temperature management to monitor and control the cascade refrigeration system, with full data logging.

The solution to successfully protect critcial products ensuring they reach their destination in perfect condition even after extended periods: seafood , active pharmaceutical Ingredients (API), mRNA vials or other biological material such as blood plasma.

The longest shelf life

Thanks to its superior cooling capacity, our Superfreezer can reach specific set-points faster and prolong the shelf life of your ultra frozen products. The key is to reach below the eutectic point to stop any bacteria growth.

With the Superfreezer unit, you get exceptionally high performance to preserve first-day product, freshness and texture of seafood (Grade A sashimi, tuna, salmon) or other proteins that must be stored below -55°C for as long as you like.

Seamless connectivity

The integrated RMM module enables telematics solutions for both one-way and two-way communication. This is the ideal solution to monitor reefer units from remote, to change set-points or retrieve a datalog file. Serial connection to other systems or data transfer via API are also available.

Technical Specifications

ISO 6346 type R22B/12RB
Operational environment The container is designed and manufactured for the carriage of deep frozen products at ambient temperature from +50°C to -30°C without effect on the strength of the structure. A Super Freezer refrigeration unit of a “one piece picture frame type” fitted to the front end frame. The container is designed with a refrigeration unit to maintain the inside space temperature from -10°C to -70°C.
Standard and regulations The containers comply with the following authorized standards and regulations: ABS, Bureau Veritas, Lloyds Register, ISO/TC-104, ISO1496-2, ISO-668, TIR, CSC. They are buit to be capable of being handled without permanent deformation on the following basis: Lifting, loaded or empty, at top corner fittings vertically by means of spreaders fitted with hooks, shackles or twist-locks. Lifting, loaded or empty, at bottom corner fittings using slings with terminal fittings at any angle between vertical and 45° to the horizontal.
Air (Q) and Heat (U) Leakages "Double thickness insulatioon, the air leakage is approximately 5 m3/hr when the inside pressure of the container is 250 Pa. The total heat loss of the container is approximately 20 W/K at mean insulation wall temperature of 20°C."
Insulation material Cyclo Pentane blown rigid polyurethane foam; Flammability SE class (Self-extinguishing). In foamed sandwich panels where acrylic adhesive is coated on the inner surface of aluminum panels and stainless steel inner linings. Gasket material used on container is Ultra Polyethylene (UPE) rubber, that operates in environment down to -80°C.
