HNJS Liquid Nitrogen Storage tanks: Superior LN2 storage tanks
HNJS Liquid Nitrogen Storage tanks: Superior LN2 storage tanks
At HNJS, we engineer and manufacture cutting-edge liquid nitrogen (LN2) storage tanks designed for the secure and efficient storage of cryogenic liquids. These tanks are primarily utilized for the preservation of liquid nitrogen at extremely low temperatures, ensuring minimal loss due to evaporation. Our tanks are built with a double-walled construction: the inner vessel is crafted from S30408 austenitic stainless steel, prized for its exceptional corrosion resistance and cryogenic toughness, while the outer shell is constructed from robust Q245R steel, providing structural integrity.
Product Highlights & Applications
HNJS cryogenic liquid storage tanks are versatile double-layer containers perfect for liquid oxygen, nitrogen, and argon. Utilizing vacuum powder insulation, these tanks come in both vertical and horizontal orientations, making them suitable for a diverse range of applications.
Industries served:
Industrial Gas Production: Safe and reliable storage for distribution.
Healthcare Facilities: Preservation of biological samples, cryosurgery applications.
Metal Processing: Controlled cooling and hardening processes.
Welding: Shielding gas storage.
Food Industry: Rapid freezing and preservation of food products.
Transportation: Secure and efficient transport of cryogenic liquids.
Key Advantages of HNJS LN2 Storage Tanks
HNJS tanks stand out in the industry due to their advanced engineering and commitment to safety and performance:
Exceptional Thermal Insulation: Our tanks employ a high-vacuum powder insulation system within the double-wall construction. The annular space is filled with carefully selected perlite insulation and meticulously evacuated to create a superior thermal barrier. This minimizes heat transfer and significantly reduces boil-off rates, leading to cost savings and optimized storage efficiency. We tailor our vacuum standards to specific tank volumes to achieve peak insulation performance.
Uncompromising Safety & Reliability: Safety is paramount. Our tanks feature a redundant safety system incorporating both primary and secondary safety valves, offering a dual layer of protection. This "main and standby" configuration allows for routine inspection and maintenance of one safety valve while the other remains fully operational, ensuring continuous and uninterrupted protection against overpressure. This proactive approach mitigates potential risks and safeguards both personnel and equipment.
User-Friendly Operation: Designed with the operator in mind, each tank is equipped with easily readable pressure gauges, differential pressure level indicators, and liquid level comparators. These instruments provide real-time, intuitive information on storage volume and pressure, simplifying filling, draining, and monitoring processes. The clear and accessible instrumentation enhances operational efficiency and reduces the potential for errors.
Customization and Flexibility: We understand that every customer has unique needs. HNJS offers both vertical and horizontal tank configurations, with storage capacities ranging from 5m³ to 200m³. The inner layer is crafted from Austenitic stainless steel(S30408) known for its high corrosion resistance, strength and toughness. Outer layer material is selected as high-quality mild steel(Q245R). We can also offer customized solutions based on regional environmental conditions and specific operational requirements.
Proactive Monitoring System: Each tank includes a dedicated vacuum valve, enabling regular vacuum level checks using a standard vacuum gauge. This proactive monitoring system allows for early detection of potential insulation breaches, ensuring the continued safe and efficient operation of the tank and preventing costly downtime.
