How do I choose between buying a tank and using gas cylinders?

Cylinders are suitable for small-scale or intermittent use. Tanks are more economical for high usage volumes, offering lower cost per liter and continuous supply. LDH can help evaluate your consumption to determine the best option.

Do cryogenic tanks require electricity or active cooling?

Most standard tanks rely on passive insulation and do not require electricity. They keep liquids cold for long periods without power. Some specialized systems may use active cooling, but standard LDH tanks are reliable without continuous power.

Can I get a custom cryogenic tank built for my specific needs?

Yes, LDH specializes in custom solutions. We can design tanks with unique capacities, materials, configurations, or features like integrated scales to meet specific industry requirements.

AI-Powered supplier vetting

SummaryThe supplier is identified as a trading company whose scope includes gas, gas separation and purification equipment, machinery, installation, technical services, and import/export activities. It reports more than ten years of gas design and R&D experience, broad customization and ODM/OEM capabilities, available SDK support, and documented procedures for supplier service assessment, corrective actions, and customer complaints. Production information states annual outputs of 300 nitrogen generator sets, 350 oxygen generator sets, and 150 liquid nitrogen generator sets, with finished-product inspection instructions followed uniformly. ISO 9001:2015 certification is reported. Financial records are indicated for 2021–2023, but no financial results are provided. Overseas support appears limited because no overseas showroom, agent, branch, or offline trade-show participation is reported. No specific customer cases are disclosed.

CertificationsThe supplier reports holding an ISO 9001:2015 certificate and also reports uniformly followed instructions for finished-product inspection. The available evidence supports quality-management certification, although no other certifications are identified.

After-Sales capabilityThe supplier reports clear procedures and followed records for handling customer complaints, corrective and preventive actions, and service-capability assessment. It also states that its technical team provides pre-sale, sales, and after-sales technical support, including installation guidance and training; however, it reports no overseas agents, branches, showroom, or overseas-service countries.

R&D capabilityThe supplier reports more than ten years of gas design and R&D experience, a professional technical team, new products during the past year, ODM services, OEM services for well-known brands, and an available SDK. These statements provide explicit evidence of established product-development and technical-support capability.

Production capacityReported annual production output is 300 nitrogen generator sets, 350 oxygen generator sets, and 150 liquid nitrogen generator sets. The supplier also reports a one-month off-peak lead time, finished-product inspection instructions that are uniformly followed, and 11–20 quality-control staff, supporting a documented production and quality-control operation.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also reports ODM availability, providing direct evidence of broad customization and original-design support.

Product Q&A

Q:How long can cryogenic liquids be stored in a tank?

Storage time depends on insulation, size, and ambient conditions. Small Dewars may hold liquid for days to weeks, while large insulated tanks can hold cryogens for months. LDH provides static evaporation rate specifications for each model.

Q:Are cryogenic tanks safe?

Tanks include safety features like pressure relief valves. Main hazards are extreme cold and oxygen displacement. Users must wear protective gear, ensure ventilation, and never seal the container tightly to prevent bursting.

Q:How do I refill or transport a cryogenic tank?

Refilling is done via transfer hoses, siphons, or tanker trucks. For transport, secure tanks upright, use transport-designed models with shock absorbers, and keep vents open to release pressure. Follow local hazardous material regulations.

Q:What maintenance is required for cryogenic tanks?

Key tasks include annual pressure relief valve checks, monitoring vacuum levels, and inspecting for exterior damage. Keep the tank clean and free of ice. LDH recommends periodic professional inspections for larger tanks.

Q:Can I store different cryogenic liquids in the same tank?

It is generally not recommended without proper cleaning and purging. Tanks are often dedicated to a single cryogen to avoid contamination. If switching, the tank must be warmed, evacuated, and purged with inert gas.
