Mirai Intex develops refrigeration machines made of high-grade components and materials to ensure their long-term, efficient and reliable operation.

Air-cycle cooling technology was developped to eliminate the use of harmful fluorinated gases, as well as prevent ozone layer depletion and global warming. With such innovative refrigeration technology, Mirai aims to contribute to reducing greenhouse gas emissions and increase the safety of refrigeration equipment operating at ultra-low temperatures.

Full portfolio covers a wide range of applications, from biomedical and food storage to the freeze-drying and liquefaction of gases.

Air cycle cooling technology for cold chain storage

Mirai Intex’s air cycle is widely used in air separation plants as a cooling stage to obtain cryogenic cold and liquify natural gas, as well as in aircraft air conditioning systems.

Mirai Intex's specialists offer support with its machines at any point in their operations.

At the heart of the system is a turbo-module unit developed and manufactured in-house for the most efficient and reliable results. The technology is based on the heating capability of air during compression and cooling down during expansion. Repetition of the compression and expansion cycles allows our machines to reach and maintain ultra-low temperatures down to -160°C.

A key technological feature is that the turboexpander and compressor are located on the same shaft. The energy produced during the expansion process is transferred through the shaft to the compressor, which reduces energy consumption by up to 30% compared with vapour compression systems.

Air is heated during compression and cooled through a series of heat exchangers before being expanded to reach ultra-low temperatures.

Principal advantage of the air cycle system is that it uses air as a refrigerant and is therefore environmentally neutral. In addition, air cycle equipment is reliable and durable, which helps reduce maintenance costs and ensure a life-long cycle with no decline in performance, unlike vapour compression cycle equipment.

Another unique feature of this technology is that it can produce useful heat and can be integrated into a building’s heat management system to provide additional heating. All Mirai Cold machines are factory equipped with a frequency inverter, which ensures they do not consume any energy other than that required to maintain set temperature conditions.

Mirai Intex has developed air bearings that eliminate the need for lubricants in the system. This ensures additional cost savings and a safe, stress-free experience for our clients.

Open and closed-cycle refrigeration systems

Open-cycle refrigeration machines from Mirai Intex supply air directly to the cold room, removing the need for evaporators and auxiliary fans inside the chamber. Because they operate at low pressure, open-cycle systems are safer than any alternative.

Mirai Cold closed-cycle machines are designed as a plug-and-play refrigeration solution for ultra-low temperatures, with environmental sustainability in mind. Multiple Mirai Cold systems can be used in a modular configuration for redundancy and convenience.

Within a closed-cycle system, the ultra-cold air is circulating only inside the refrigeration machine in a closed loop. Due to this, closed-cycle machines are equipped with an additional heat exchanger for the secondary working fluid.

The best example of a secondary medium would be silicone oil, for which Mirai Cold machines are optimised. The secondary loop can cool down numerous applications requiring ultra-low temperatures. Our machines can be easily retrofitted to applications that have been using conventional or outdated cooling methods or used as a refrigeration unit for brand new installations.

Real-time, remote monitoring of refrigeration systems

Mirai Cold machines have an integrated control system with an easy-to-use touchscreen interface. Digital communication protocols such as Profi NET, EtherCAT, EtherNET/IP and Powerlink are integrated across all Mirai Cold solutions.

The system offers real-time and remote monitoring options, as well as data archiving capabilities. Remote monitoring allows users to check or set the machine’s performance and update its software online.

Mirai Intex’s team offers troubleshooting and other support during all machines’ operational lifespans, as well as regular check-ups to assess their condition and performance.

Humidity extraction technology for cold chain storage

At extremely low temperatures, moisture instantly turns to ice and the air circulating in the system must be ice-free. To address this, Mirai Intex has developed the Snow Catcher, a humidity extraction device (HED) designed to make regular defrosting procedures a thing of the past.

The HED allows Mirai Cold machines to operate continuously without defrosting procedures, which consume operating cooling power and additional energy. It is very easy to install – only a few holes need to be cut in the cold chamber wall to connect Mirai Cold and the Snow Catcher.
