The transition from virtual exhibitions to real life has happened! Now even more people have been able to experience the power of Mirai's air-cycle refrigeration technology.

MIRAI at Medica 2021

A visit to the chamber in the container generated a great deal of excitement and interest. Visitors were invited to try out the technology proper and what the all-in-one storage solution looks like. KTI's turnkey solution for storing vaccines and biological material was presented at the fair in Düsseldorf.

The mobile ULT-storage uses innovative and environmentally friendly air-cycle refrigeration technology. The refrigeration machine Mirai Cold 10 main component is an oil-free turbo module that compresses and expands air and transfers it on a single shaft for energy recovery. Air as a refrigerant is natural, free, non-toxic, non-flammable, and safe for humans and the environment!

The turnkey solution for ULT store design consists of an airlock zone at -20°C and the ultra-low-temperature section down to -110°C. The two-chamber principle avoids high infiltration of heat and humidity from the outside air and guarantees the highest efficiency.

​An unbeatable solution built inside of a CSC-certified 40 ft. container that can easily be transported in every corner of the world without assembly or commissioning work.

The main benefits of the solution are following:


Only natural refrigerants are used - Air for the ULT chamber, CO2 for the air lock zone and propane for cooling of both systems.

With this solution, the customer is completely independent of the phase-out of synthetic refrigerants and can use the storage for decades.



Innovative technology using only one compressor, compared to cascade systems that depend on multiple compressors running simultaneously, is a win-win for reliability and convenience.

Our technology has no phase change, no oil, and thanks to the air bearing, it is not subject to wear and tear.



Thanks to the dual-chamber principle, which avoids high heat infiltration from the outside air and humidity, the solution boasts the highest degree of efficiency. There is no equivalent on the market that can compete with Mirai's innovative air-cycle refrigeration technology; it is most effective at temperatures around -70°C.

The air as a refrigerant is free, which makes the technology very economical to operate.

HED (Snow catcher) allows to forget about the defrosting procedure as it traps the humid particles and extracts it automatically from the chamber.



A plug&play solution.No additional construction work is necessary. Shipping the container worldwide is absolutely possible!



The adjustable temperature, ranging from -30°C to -110°C in just a couple of clicks, in the presented KTI solution is optimized for -80°C.

The ULT storage container is therefore suitable for storing various substances at the right temperature with flexible temperature adjustment.



Compact design with a storage capacity of 25m³, easy to add to existing storage facilities.

Reliable and innovative technology guarantees high availability with low maintenance.
