Amid the ongoing energy crisis, MIRAI INTEX is at the forefront of innovation, introducing three solutions designed to revolutionise the biogas liquefaction process: MIRAI Cold 50 LNG, MIRAI Cold 90 LNG, and MIRAI Cold 150 LNG, comprising an extended range of LNG machines.

The MIRAI LNG series represents advanced refrigeration machines meticulously crafted for the liquefaction of biomethane. Derived from the proven success of our standard MIRAI Cold series, the LNG series has been specially modified to meet the demands of the liquefaction process. Equipped with a range of safety features, high-temperature protection, sensor failure protection, and gas leakage protection, MIRAI’s machines not only comply with international standards but also ensure a secure and efficient operation.
Moreover, we at Mirai provide a Monitoring System for all our refrigeration solutions. For the customers, who want to enhance safety and increase the longevity of their projects, this solution is the perfect choice. You can choose the advanced Remote Access System (RAS) or Remote Monitoring System (RMS) accordingly.

Driven by an inverter for optimal part-load performance, the MIRAI Cold LNG line utilises nitrogen as a natural and environmentally friendly refrigerant. With a direct connection to the client’s condensate heat exchanger, it stands as a universal solution for diverse biogas liquefaction productions.


The largest-scale solution for bio-LNG liquefaction processes is represented by MIRAI Cold 150 LNG. Building upon the success of its predecessor, the 150 LNG incorporates similar safety features, an inverter-driven system, and the use of nitrogen as a refrigerant. This model, with its increased capacity, is ideal for meeting the demands of medium scale BioLNG/LNG productions and reliquefication of BioLNG/LNG or there is also option to take and advantage of the modularity and connect more MIRAI LNG systems in one production station.

In summary, MIRAI Cold 50 LNG, MIRAI Cold 90 LNG, and MIRAI Cold 150 LNG are innovative solutions that embody our commitment to the global protection of our planet. Their safety features, adaptability, and energy efficiency make them indispensable tools in the pursuit of sustainable and efficient biogas liquefaction processes, propelling us towards a cleaner and more secure energy future, in line with the ambitious goals of the Green Deal stated by the European Union and confirmed by the agreement  signed by 200 countries during the United Nations Climate Change Conference (COP28) in Dubai that signals the “beginning of the end” of the fossil fuel era by laying the ground for transition.

Benefits and applications of LNG systems

Bio LNG is a cold renewable biofuel that can be produced anywhere where anaerobic digestion (AD) and upgrading for liquefaction is possible. Anaerobic digestion and the production of bio-LNG can effectively address issues of clean energy production, environmental conservation, and waste management.

Biogas is upgraded and liquified into Bio LNG, consisting of almost 100% methane. This gas is a renewable form of energy and liquifying the biogas increases the valuation of the gas. Bio LNG (also known as liquefied biomethane) is ideal for manufacturing and industrial businesses with energy-intensive operations, as well as the transport industry.

MIRAI developed process designs with MIRAI Cold LNG solutions for various productions capacity (available for 3t, 5t, 10t, 15t and 20t of liquefied gas each day).
