Features
MIRAI Cold 140 LNG is a refrigeration system designed for biomethane liquefaction, utilizing a natural and environmentally friendly refrigerant—nitrogen. The system operates on a closed-loop principle, with the heat exchanger positioned externally. It includes robust safety measures that prevent leakage of the cooled substance into the internal cycle, ensuring safe and efficient operation.

Key safety features and protections integrated into MIRAI Cold 140 LNG include high-pressure protection, water supply cut-off protection, over-current protection, sequential and phase failure protection, high-temperature protection, sensor failure protection, gas leakage detection, and a housing ventilation system. Additionally, the machine is safeguarded against direct moisture exposure, rodents, and sunlight.

For optimal operation, MIRAI Cold 140 LNG must be installed under a protective canopy or roof, as it is not designed for exposure to open-air conditions.

A distinctive advantage of MIRAI Cold 140 LNG is its flexibility and ability to seamlessly connect with any biomethane liquefaction process without requiring additional modifications or system reconfiguration.
