Closed Cycle

Circulation of ultracold air inside the cooling unit. The machines are equipped with an additional heat exchanger for the secondary working fluid.
-40°c -110°c
Temperature range
10-80 kW
Motor power
Features
Great advantage - environmental neutrality of the system, using air as the refrigerant. Air cycle equipment is substantially reliable and durable, reducing maintenance costs and ensuring cycle longevity without performance degradation, unlike steam compression cycle equipment.

A unique feature – production of useful heat and integration into a building's heat management system.

Remote monitoring
An integrated control system with easy-to-use touchscreen interface and integration of digital communication protocols such as ProfiNET, EtherCAT, EtherNET/IP and Powerlink come as standard.

The system offers real-time monitoring, data archiving and remote monitoring as options. Remote monitoring allows you to check and log machine performance, as well as update machine software online.
Support from Mirai Intex during machine’s operation and during troubleshooting
Detection and prevention of problems
Regular check-ups of machine condition and performance
System Pressurization Unit
MIRAI Cold refrigeration machines are running only with gaseous air as refrigerant which cannot change its state to liquid
With the optional System Pressurization Unit, MIRAI Cold machines are capable of matching required operating conditions and can charge or drain the appropriate amount of air from the refrigeration cycle. Required air purity for MIRAI Cold is 1.2.1 (according to ISO 8753).

Mirai Intex has developed high-quality automated charging system available as an optional accessory for MIRAI Cold T models. This option is fully integrated inside the machine housing and therefore does not require any additional space. And since it is installed at the factory it goes through all testing procedures with the machine.

New Product line for Hydrogen re-Fueling Stations
We are proud to announce the launch of an entirely new machine line – MIRAI H2. Line developed and designed to help grow the number of Hydrogen Fueling Stations using refrigeration technology with zero ecological impact. MIRAI H2 units were developed with attention to safety related to hydrogen use. Additional safety systems, features, and special software is part of the MIRAI H2 package. One particular change for MIRAI H2 is the use of Nitrogen instead of Air due to safety reasons.
Machines are optimized to provide cooling capacity to respect SAE J2601 for T40 dispensers which means the turbo-modules design temperature was -40 °C.

Freeze Drying
Freeze drying is a freeze drying process in which water is removed from the product after it has been frozen and placed under vacuum, thus allowing the ice crystals to pass directly from the solid state to the vapour state. The process is based on the physical phenomenon of sublimation, which allows a direct transition from the solid to the liquid state. Lyophilisation is mainly used in pharmaceutical and biotechnological research and the industrial production of cosmetic products or drugs such as tablets but also in the drying of foodstuffs and the preservation of archival materials (i.e. books and documents).
Process Cooling
Large industrial plants or facilities need to cool their production processes almost all year round. Mirai solution is not only environmentally friendly and free of any F-gases or oils, but it is also extremely efficient. The primary role of cooling systems in industrial refrigeration systems is not only to be extremely efficient, reliable and cost-effective, but also to improve the initial production processes and contribute to environmental protection.
Solvent Recovery
Solvent Recovery is based on the fact that the vapor of a boiling mixture will be richer in low boiling point components such as alcohols, acetones, aliphatic hydrocarbons and, ketones. When the vapor is cooled and condensed, the liquid condensate becomes a valuable product that can be sold back into the industrial marketplace. A solvent recovery system is the preferred recycling method among many industrial manufacturers since it provides a cost-effective solvent recuperation solution and minimizes adverse environmental effects. Only natural refrigerant (AIR) is used in multiple stages of the refrigeration process. The ultra-low temperature process is realized with a MIRAI INTEX air cycle refrigeration solution MIRAI Cold.
