The mobile KTI ULT-Store uses innovative and environmentally friendly air-cycle refrigeration technology from MIRAI. 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 the ULT store design consists of an air lock zone at -20°C and an 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 a CSC-certified 40ft container that can easily be transported in every corner of the world without assembly or commissioning work.

The main benefits of the solution are as follows:


Only natural refrigerants are used – air for the ULT chamber, carbon dioxide for the airlock zone, and propane for cooling 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 with cascade systems that depend on multiple compressors running simultaneously, is a win-win for reliability and convenience.

Our technology has no phase change or 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 of around -70°C.

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

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


A plug and play solution. No additional construction 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 optimised for -80°C.

The ULT storage container is therefore suitable for storing various substances at the correct temperatures 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.
