MIRAI Cold 10 T is the refrigeration machine designed for the sustainable generation of Ultra-low temperatures. Our machine is particularly efficient at producing temperatures from -40 ° C to -110 ° C in a single cascade and can control with an accuracy down to 0.5 K and adjust steplessly. The refrigeration system transfers the waste heat directly to cooling water. No additional refrigeration system is required for efficient operation.
The technical basis of our machines is the air cycle refrigeration technology.
This is a reverse Joule cycle with air as a refrigerant. The air is compressed and expanded after cooling in a series of heat exchangers. By repeating compression and expansion cycles, Ultra-low temperatures can be reached and maintained down to -110 ° C. The minimal temperature is limited in accordance with the limit of the secondary cooling fluid (Silicone oil).
All machines are supplied as stand-alone units with required insulation and removable housing cover.
The devices have an integrated control cabinet including a compact controller. Our control system allows the customer to communicate with their control system using the digital protocols ProfiNET, EtherCAT, EtherNET/IP and Powerlink, which provides easy integration. Please specify the type of digital protocol when ordering.
The HMI is a touch display IP66 (front).
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.
This specific model has been developed for applications such as Freeze-drying, process cooling and others. The MIRAI Cold 10 T comes with an additional heatexchanger for cooling of the working fluid of your choice. It is easy in maintenance and operation.
The system requires pressurized air supply from 6 to 8 bar with air quality of second category. Dew point at -40ºC.
Automated machine pressurisation system is available as an option at additional cost.
The system is available in different configurations, which allows us to provide cooling for a wider range of applications:
Closed refrigeration cycle
The closed circuit can be operated as an indirect system with air as the refrigerant. This has the advantage that it shields the area to be cooled and does not react with the substances to be cooled. We are happy to advise you personally with selecting a heat-exchanger for your applications.
In case you believe that you need a solution that is more specific please send us detailed information about your cooling requirements through our configurator and we will provide you with the right solution for your needs.

The advantages of properly freeze-dried products are that they do not need refrigeration and can be stored at ambient temperatures. A freeze-dried product retains its original nutritional value, texture, product shape, and taste. It is the fresh product with just the water removed – and nothing added.
MIRAI Cold refrigeration machines are compatible with any industrial process due to safety of the refrigerant, lack of the oil in the system and exceptional reliability of the system.
