MIRAI Cold 10 (MC 10 O/W)

MIRAI Cold 10 – an air cycle refrigeration machine designed to provide and maintain ultra-low temperatures from -60 °C down to -110 °C in cold chambers.

MIRAI Cold 10 operates in an open cycle and provides ultra-cold air directly into the chamber, without the need of an evaporator and auxiliary fans inside the chamber. Our open cycle refrigeration machines are supplied with a unique humidity extraction device, which traps the humidity from the air in the chamber and extracts it mechanically. Thus, eliminating the buildup of ice and frequent defrost procedures, making our MIRAI Cold 10 machine a perfect solution for long term storage needs at ultra-low temperatures. Applications of our machines include biological/pharmaceutical materials storage, storage of meat and fish, as well as creating a unique experience in a cryotherapy chamber.

MIRAI Cold is a new generation of sustainable refrigeration machines using the air cycle technology (reversed Brayton Cycle).

Air Cycle Technology is based on the heating capability of air during compression and cooling down during the expansion process. Repetition of compression and expansion cycles allows us to reach and maintain ultra-low temperatures down to -110 °C.

SYSTEM COOLING  Water-cooled
DIMENSIONS (L x W x H)  103 x 145 x 179 cm

MC10 control system

All MIRAI Cold machines are supplied as stand-alone units with required insulation and removable housing cover. The control panel is rated IP66.

MIRAI Cold machines have an integrated control system that allows the customer to communicate with their control system using the digital communication protocols ProfiNET, EtherCAT, EtherNET/IP, and Powerlink, which provides easy integration. The system offers real-time monitoring, data archiving at specified intervals, and remote monitoring as an option.

One of the key features of the technology is, that the turbo-expander is located on the same shaft as the turbo-compressor.

The energy produced during the expansion process is shared by the compressor, thus significantly reducing energy consumption. This feature allows us to reduce energy consumption by 30%, as compared to conventional systems.

Open refrigeration cycle

In the case of an open cycle machine, the ultra-cold air is supplied directly to the cold room (or any other form of refrigerated well-insulated closed space). Typical refrigerants work only in closed loops, and refrigerant leaks are a big problem of the refrigeration system itself, and harm to the environment is almost inevitable. This all is not applicable when Air is used as a refrigerant.

Air (refrigerant) is provided straight to the refrigerated space and there is no need for evaporators or auxiliary fans inside. At ultra-low temperatures humidity crystalizes into ice instantly and the Air circulating in the system has to be ice-free. For that reason, Mirai Intex has developed a unique Humidity Extraction Device. This device traps all the humidity inside the refrigerated space and extracts it mechanically as snow. It operates automatically and therefore eliminates the need for defrosting procedures, ensuring the most stable condition for long term storage.

Applications of open cycle machines include biological/pharmaceutical materials storage, storage of meat and fish, as well as creating a unique experience in a cryotherapy chamber.
