Member news: Mirai Intex releases new high capacity ultra-low temperature refrigeration system

Mirai Intex, corporate member of the IIR, has released a new ultra-low temperature (ULT) system based on air-cycle technology, offering high cooling capacity.

IIR corporate member Mirai Intex has released a new refrigeration system for ultra-low temperature (ULT) applications. Designed for process cooling and freeze-drying applications, the Mirai Cold 80 C/W/T (MC 80 T) works in a closed cycle and is cooled by water. The system is also equipped with an additional heat exchanger for a secondary cooling medium.


Like previous Mirai Intex’s ULT systems, the MC 80 T uses natural air (R729), which has a GWP of 0, as refrigerant. The air-cycle technology is based on the heating capability of the air during the compression stage and the cooling down capability during the expansion process. Repeating of compression and expansion cycles allows to reach and maintain ultra-low temperatures. Furthermore, no oil is required for lubrication in this model thanks to the absence of contacting pairs.


Offering a large cooling capacity of up to 55 kW, the MC 80 T functions in a temperature range from -40°C to -110°C. Equipped with a separate electrical cabinet with a touch-screen control system, various installation layout options are possible since the electrical cabinet can be located further away from the machine.  


Other features of the system include:

- Advanced control system regulating machine performance

- Frequency inverter for precise partial load operation

- Integration of communication protocols (ProfiNET, EtherCAT, EtherNET/IP and Powerlink)

- Remote monitoring and remote software updates

- Compact dimensions in relation to the refrigeration capacity provided

- High cooling capacity with the same noise level as smaller machines
