BASICS OF THE TECHNOLOGY

MIRAI Cryo is the refrigeration machine for the sustainable generation of Ultra-low temperatures. Our machine is particularly efficient at producing temperatures from – 130 ° C to – 160 ° C and can control with an accuracy down to 0.5 K and adjust steplessly. The refrigeration system transfers the waste heat directly to the surrounding air or cooling water. No additional refrigeration system is required for efficient operation.

The machine can be operated as an open circuit for direct cooling of the air or as an indirect closed system with the inert gas nitrogen. The advantages of the open cycle refrigeration can be found on this page below.

The technical basis of our machines is the air cycle refrigeration technology.

This is a reverse Joule cycle with air as the 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 -160 ° C (optional).

SYSTEM CONTROL

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 with the fast real-time bus system and EtherCAT master. The HMI is a touch display IP66 (front) is used. Optionally, various slave interfaces or a higher-level master control are available.

For devices with an open air circuit, there is also a specially developed air de-humidification system available. Thus, the refrigeration machines from Mirai meet all legal, environmental and procedural requirements in order to sustainably optimize your application.

SPECIFICATION

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.

VARIANTS

The system is available in different configurations, which allows us to react on a wider range of conditions:

  • Closed refrigeration cycle
  • Water cooled

Closed refrigeration cycle

The closed circuit can be operated as an indirect system with the inert gas nitrogen (N2). This has the advantage that it shields the area to be cooled and does not react with the substances to be cooled at the exit. In the dimensioning of the heat exchanger for your application, we are happy to advise you personally.


In case you believe that you need solution that is more specific please send us detailed information about your conditions through our configurator and we will provide you with the right solution for your needs.
