ADVANTAGES OF ULT SPACE COOLER

Safety and Environmental Responsibility
ULT SPACE COOLER units use R729 as the refrigerant — ordinary air that is completely safe for people and the environment. No chemicals, no harmful leaks, no risks for personnel — only clean, thermally processed air.
Efficiency at partial load
ULT SPACE COOLER systems operate reliably within a capacity range from 10% to 100%, with almost no loss of efficiency. This reduces energy consumption, lowers the load on the power network, and decreases operating costs from the very first days of operation.
Consistently High Performance (No Degradation Over Time)
The absence of friction parts, a lubrication system, and evaporator icing stops the system from breaking down and lets the unit keep its high efficiency and cooling power in the chamber for its whole service life.
High Energy Efficiency
The absence of heat exchangers, fans, and supporting structures prevents loss of useful cooling capacity and avoiding unnecessary heat input. ULT SPACE COOLER operates reliably even at extremely low temperatures.
Low Operating Costs
ULT SPACE COOLER does not require refrigerant refilling, oil replacement, or maintenance of oil pumps. The gas-dynamic bearings, as well as the entire turbo compressor, are designed for up to 20 years of operation, reducing the risk of failures and service costs.
No Frost Formation
The HED (Humidity Extraction Device) system mechanically removes moisture and ice particles from incoming air, reducing frost formation inside the chamber. The absence of ice build-up and defrost cycles ensures continuous cooling and stable, uniform temperature control.
Reliable Design
MIRAI INTEX uses an open air cycle without external heat exchangers, liquids, phase changes, or lubricants. The simplicity of the design increases system reliability and reduces the chance of failures.
Simple Chamber Integration
The MIRAI ULT SPACE COOLER connects directly to the chamber where the Snow Catcher is installed, without complex engineering or lengthy installation.
Wide Temperature Range and Easy Control
The system operates reliably within a temperature range of −40 °C to −130 °C with an accuracy of ±0.5 °C. The chamber temperature can be set via a touchscreen interface in just a few clicks, and the system reaches the target value without interrupting operation.
Low Noise and No Vibrations
The absence of fans and conventional compressors ensures minimal noise levels. The turbo compressor operates without vibrations, making it ideal for pharmaceutical and other critical industrial applications.

ULT SPACE COOLER APPLICATIONS

Biomedical Storage

Preservation of precious and delicate items or testing their duration through the most extreme conditions is only some of the things our solution can provide. Keep samples and sensitive materials in a homogenous environment all years round without harm.

Metal Hardening

Cryogenic steel treatment is carried out at temperatures between -70°C and -120°C for one hour. It increases hardness and wear resistance by converting a higher proportion of austenite to martensite. The cooling room for cryogenic steel hardening consists of two rooms separated by a permeable barrier. Therefore, two different batches can be hardened in one machine. A heat exchange takes place between a new batch and the warm batch before the warm batch has to be cooled down to the required temperatures using an air cycle machine. This saves some of the refrigeration capacity required for cooling and reduces operating costs.

Pharma Storage

Storage, management and transportation of life-saving products such as vaccines, pharmaceuticals require a precisely coordinated chain of events under controlled temperature conditions. Temperature accuracy and quality assurance are key requirements for manufacturers. Temperature uniformity, optimum storage temperatures, electrical equipment and surface area are decisive factors in the energy efficiency of a cold store. With reliable systems, the manufacturer will never be exposed to material losses in the form of spoiled vaccines or pharmaceuticals.

Climate Testing

Testing is an important part of the product development process, control at all stages of production and pre-sale preparation of equipment, products, and devices. The main indicator of the quality of any product is resistance to temperature effects. With highly reliable refrigeration system MIRAI COLD set and maintained temperatures have an accuracy down to the 0.5ºC via the integrated variable speed drive on the compressor.

Cryogenic Storage

Cryogenic storage of biological materials usually requires temperatures below - 130 °C. Ultra-low temperatures are achieved by cooling with clean air. Machines with temperatures down to -160 degrees Celsius are designed according to personal design and request. Cryogenic storage needs to be foremost stable and reliable for you to be sure that stored samples are in the best conditions.

Logistic Transport

Logistic transport with ultra-low temperature capabilities is a specialized service designed to safely and efficiently transport sensitive goods that require maintenance at extremely low temperatures, typically ranging from -40°C to -150°C. This type of logistics is crucial for sectors such as healthcare, pharmaceuticals, and biotechnology, where the integrity of products like vaccines, biological samples, and certain chemicals must be preserved throughout the transportation process. Equipped with advanced cooling technologies and real-time temperature monitoring systems, these transport solutions ensure that the products remain within their required temperature range, minimizing the risk of degradation or loss of potency.

Food Storage

Storing food at -60°С stops all intra-cellular biochemical processes and denaturation of proteins, doesn’t damage tissue cells and prevents the formation of large ice crystals as it occurs at -18°C.

Cryotherapy

Cryotherapy is mainly used to relieve muscle pain, sprains and swelling after soft tissue injuries (sports) or surgery, as well as to improve recovery after sports activities. The treatment involves exposing individuals to extremely cold dry air from − 100 °C down to – 160°C for 2-4 minutes. During these exposures, individuals wear minimal clothing to maximize the effects of cryotherapy.

How the open cycle systems works

Air is heated during compression and cooled through a series of heat exchanger sand then expanded to reach ultra-low temperatures.
While repeating the cycle of compression, cooling and expansion we can achieve temperatures down to -160°C.
