Energy Efficient Ultra-low Temperature Refrigeration System

MIRAI INTEX has engineered an energy efficient ultra-low temperature refrigeration system which can reliably sustain temperatures ranging from -40°C to -110°C (-40°F to -166°F) with ±0,5 °C accuracy, whilst saving up to 30% in energy costs.

The MIRAI Cold 22 (MC 22 O/W) is a state-of-the-art air cycle technology ultra-low temperature refrigeration system where each component has been designed for maximum efficiency and reliability.

Energy Efficient Ultra-low Temperature Refrigeration System (down to -110 °C)

MIRAI Cold 22 represents a new generation of sustainable Ultra-low Temperature (ULT) refrigeration systems using the air cycle technology (reversed Brayton Cycle) which drastically cuts energy consumption and operational costs and ensures reliability, safety and compliance with environmental legislation.

The Air Cycle Technology is underpinned by the heating capability of air during compression and cooling down during the expansion process. The repeated compression and expansion cycles facilitate achieving and maintaining ultra-low temperatures ranging from -40°C down to -110°C in cold chambers. One of the key advantages of this technology is its energy efficiency, which can help reduce running costs by up to 30%.

Unique humidity extraction for effective long-term ULT storage

The MIRAI Cold 22 refrigeration system employs an open cycle to deliver ultra-cold airflow straight to the chamber eliminating the need for an evaporator and auxiliary fans. The open cycle ULT refrigeration units manufactured by MIRAI, are equipped with a unique Humidity Extraction Device (Snow catcher) that mechanically captures and eliminates the air humidity from the chamber. The MIRAI Cold 22 is excellent for short-term as well as long-term storage needs at ultra-low temperatures since the humidity extraction mechanism avoids ice formation and frequent defrost procedures.

Safe and efficient solution for preservation and storage of biological or pharmaceutical materials

The MIRAI low energy consumption ultra-low temperature refrigeration system can be employed as a safe and efficient solution for the preservation and storage of biological or pharmaceutical materials, as well as providing a novel cryotherapy chamber experience.

MIRAI Cold is a new generation of environmentally friendly and energy efficient refrigeration systems, that are reliable and ideally suited for applications in the pharmaceutical industry, biomedical and diagnostics field, as well as many other industries.

For biomedical storage, ULT refrigeration can help with the preservation of valuable and delicate goods such as tissue cells, as well as assess their durability under the most extreme conditions. With the MIRAI Cold 22, keeping sensitive materials and samples safely protected in a consistent environment all year long is easy.

No hazardous chemicals – just fresh air

Air Cycle Technology offers many advantages compared to conventional systems using chemical refrigerants. Notably providing green energy not only cuts energy consumption costs but also provides increased safety and compliance with any upcoming environmental legislation and requirements.

Advanced real-time and remote temperature monitoring

All of the MIRAI Cold range refrigeration units come with an integrated digital control system that enables easy integration for real-time monitoring, data archiving, as well as remote monitoring as an option. For the pharmaceutical sector, where ensuring the right temperature conditions of goods, such as vaccines, is of vital importance, these options offer huge benefits for safe storage and supply.
