Industrial Nitrogen Liquefaction Unit

1. Product Overview

Nitrogen liquefaction unit — converts ambient-temperature nitrogen into liquid nitrogen through compression, purification, and low-temperature heat exchange. The system integrates pretreatment, a cold box, expansion refrigeration, a storage tank, and automatic control instrumentation. Upstream purification removes impurities, and the insulated cold-retention structure reduces liquid nitrogen boil-off losses. It continuously produces high-purity liquid nitrogen with complete safety protections, meeting industrial liquid nitrogen supply requirements.

2. Features

• Continuous liquid nitrogen production with stable product purity.

• High-efficiency insulation with low evaporation losses.

• Feedstock pretreatment ensuring clean medium.

• Adjustable production capacity and load.

• Complete pressure and level safety interlocks.

3. Applications

Electronics cryogenic cooling, food quick-freezing, biopharmaceutical freezing, cryogenic treatment of metals, and liquid nitrogen production at industrial gas stations.
