The HUILIN carbon deoxygenation type nitrogen purification device adopts a carbon combustion deoxygenation+adsorption drying method, using a carbon supported catalyst. The trace oxygen in ordinary nitrogen is burned with carbon to remove oxygen. Its chemical reaction formula is C+O₂ → CO₂, and then impurities such as CO₂ and dust are removed through adsorption drying device to obtain high-purity nitrogen. It is an advanced nitrogen production equipment that can obtain high-purity nitrogen gas (≥ 99.999%) at low cost.

The HUILIN containerized nitrogen generator integrates an air compressor, purification system, oxygen-nitrogen separation system, control system, and other components into a standard container. The equipment is ready to use upon arrival, easy to move, and suitable for outdoor, temporary, and remote scenarios.

The HUILIN oxygen cylinder filling system consists of two core units: an oil-free oxygen compressor and a high-pressure filling manifold, suitable for steel cylinder filling operations in conjunction with PSA oxygen production. The compressor features multi-stage oil-free boosting to prevent oil and grease contamination of the oxygen, and is equipped with multiple safety protections against overtemperature and overpressure. The filling manifold integrates a high-pressure valve group, pressure gauge, and safety valve, allowing for grouped and alternating cylinder filling, making operation convenient. The entire system is clean and explosion-proof, with stable pressure, meeting industrial and medical oxygen filling standards. It supports customized cylinder filling stations as needed, operates safely and efficiently, and is suitable for use in conjunction with various small and medium-sized oxygen filling stations.

The HUILIN medical compressed air system consists of an air compressor, a dryer, a filter, an air storage tank, and a monitoring device. The equipment purifies the air in multiple stages, including drying, oil removal, and water removal, producing clean compressed air that meets medical standards, with no impurities, low dew point, and stable pressure. Mainly supplied to operating rooms, ventilators, anesthesia equipment, dental diagnosis and treatment, ward oxygen supply assistance and other departments.

Designed for a centralized vacuum production in hospitals and clinics, HUILIN Vacuum Stations ensure the continuous supply of the medical gas piping system. Fully automatic, they comply with the most demanding quality standards and require very little maintenance.

HUILIN Liquid Nitrogen Generator Working principle
The cryogenic mixed refrigerant throttle refrigerator is adopted in this nitrogen liquefier. It is based on the regenerative multi-component mixed refrigerant throttle refrigeration cycle. The high, middle and low boiling point pure components are selected to compose multi-component mixed refrigerants. The relay matching of effective refrigeration temperature zones of each boiling point component is realized. It can be cooled from ambient temperature to -196° C, the purpose of nitrogen liquefaction (-180° C @ 0.6 Mpa) is achieved.

HUILIN VPSA oxygen generator is a vacuum pressure swing adsorption oxygen production equipment. It uses air as raw material and utilizes the characteristics of molecular sieves to preferentially adsorb nitrogen and desorb under negative pressure, achieving oxygen and nitrogen separation through a "positive pressure adsorption vacuum desorption" cycle. The system consists of a blower, vacuum pump, adsorption tower, buffer tank, and PLC self-control. The two towers work alternately to continuously produce oxygen with a purity of 90% -95%. Compared to PSA, VPSA has lower regeneration energy consumption, higher recovery rate, and larger single machine oxygen production scale, making it suitable for high flow industrial oxygen supply scenarios such as metallurgy, chemical industry, and environmental protection.

For industrials looking for a safe and autonomous supply of oxygen, HUILIN introduces modular oxygen generator delivering a continuous flow of oxygen 95% produced on-site.
