Ultra-Large Self-pressurized Liquid Nitrogen Tank YDZ-1000

| Product Overview

The YDZ-1000 Liquid Nitrogen Tank is a heavy-duty self-pressurizing cryogenic container designed by Zhonghuo to meet the high-volume storage and transport demands of industrial production and large-scale laboratories. Boasting an effective capacity of 1000L and geometric volume of 1050L, this tank features overall dimensions of 1410×1920MM, a net weight of 375KG, and a full weight of 1170KG. Operating at a maximum pressure of ≤0.1Mpa, it delivers a low daily evaporation rate of 1.10% and an impressive flow rate of ≥20L/Min, ensuring continuous and stable liquid nitrogen supply. Constructed with high-strength austenitic stainless steel, a multi-layer insulation vacuum interlayer, and precision-engineered components (including a Hongqi pressure gauge and safety valve), the tank maintains the -196°C ultra-low temperature required for large-scale cryogenic applications. Equipped with mobile casters and a user-friendly control panel, it combines industrial-grade performance with operational flexibility.

| Core Advantages

Large-Capacity & High-Flow Efficiency

With a 1000L effective capacity, the YDZ-1000 caters to high-volume liquid nitrogen needs, eliminating frequent refills in industrial settings. Its self-pressurization system enables rapid automatic discharge at ≥20L/Min, making it ideal for continuous liquid nitrogen replenishment for production lines, large storage tanks, or multiple laboratory devices. This high-flow design boosts productivity and reduces downtime in demanding workflows.

Advanced Thermal Insulation & Stability

The tank’s high-vacuum insulation structure, paired with a stainless steel liner and outer tube, minimizes heat transfer and reduces daily evaporation loss to just 1.10%. The integrated sorbent and reinforced vacuum cover enhance insulation durability, ensuring consistent low-temperature performance even during long-distance transport or extended storage. This stability is critical for preserving large batches of sensitive samples or materials.

Industrial-Grade Durability & Mobility

Built with heavy-duty austenitic stainless steel, the YDZ-1000 withstands the rigors of industrial environments, including frequent movement and exposure to varying temperatures. The bottom braking casters provide smooth mobility across factories or large laboratories, while the reinforced armrest ring facilitates safe handling. Optional upgrades like remote monitoring software allow real-time tracking of liquid level and pressure, enhancing operational control.

| Application Fields

Industrial Manufacturing & Metallurgy

Widely used for deep cryogenic treatment of metal components, alloys, and precision parts in the mold and automotive industries. The -196°C treatment improves material hardness, wear resistance, and fatigue strength, extending the service life of tools and machinery. It also enables dimensional stabilization of precision parts, supporting high-precision assembly processes.

Large-Scale Biomedical & Pharmaceutical

Ideal for large pharmaceutical companies and research institutions requiring mass preservation of vaccines, cell lines, and biological reagents. The 1000L capacity accommodates large sample inventories, supporting vaccine production, clinical trials, and regenerative medicine research. Its reliable insulation ensures sample viability over extended periods.

Aerospace & Military Technology

Meets the strict cryogenic requirements of aerospace component testing, satellite equipment cooling, and military hardware development. The tank’s robust structure and stable performance make it suitable for harsh field conditions, providing a consistent cold source for critical experiments and equipment operation.

Agricultural & Livestock Breeding

Supports large-scale animal husbandry operations by enabling long-term preservation and transport of semen from elite breeding stock. It facilitates artificial insemination programs for cattle, sheep, and rare animals, helping improve herd genetic quality and agricultural productivity.

| Operation & Safety Guidelines

Pre-Operation Checks

Structural Inspection: Examine the tank shell for damage, ensure the vacuum exhaust port is intact, and confirm all valves (vent, enter/drain, safety) are functioning properly.

Accessory Verification: Check lifting equipment, liquid level indicators, and pressure gauges for accuracy and damage. Replace any worn or defective parts before use.

Pre-Cooling Protocol: For new or idle tanks, inject 1/10 of the total capacity of liquid nitrogen to pre-cool the liner. Wait 30-60 minutes until boiling stops before full filling.

Safe Operation & Filling

Mandatory PPE: Wear cryogenic-resistant gloves, a face shield, a long-sleeved lab coat, and ankle-covering pants to prevent cold burns.

Ventilation Requirement: Operate in a well-ventilated area or install nitrogen gas detectors to avoid oxygen depletion.

Filling Best Practices: Use a dedicated transfer tube to pour liquid nitrogen slowly along the inner wall. Do not exceed 80%-90% capacity to allow for expansion.

Maintenance & Storage

Regular Cleaning: Wipe the exterior with a dry cloth; for internal cleaning, rinse with 40-50°C water after emptying and air dry completely.

Monthly Inspections: Check the neck plug seal, safety valve, and pressure gauge for damage. Log liquid nitrogen usage and address frost buildup on the shell promptly.

Safe Storage: Keep the tank upright in a cool, dry, and well-ventilated area, away from heat sources and confined spaces.

| Production Process

The YDZ-1000 is manufactured through a precision-engineered production process adhering to international cryogenic standards. It starts with high-quality stainless steel sheet cutting, followed by robotic welding to ensure seamless, leak-proof joints. The vacuum interlayer is created via multi-stage evacuation, with insulation materials carefully installed to maximize thermal efficiency. Key components like the pressure gauge (Hongqi) and safety valve undergo strict pressure testing to ensure compliance with ≤0.1Mpa operating standards. Final assembly includes installing casters, control valves, and monitoring devices, followed by comprehensive performance testing (evaporation rate, pressure holding, and leak detection) to guarantee reliability. Each tank is inspected by quality control experts before leaving the factory, ensuring industrial-grade performance.

| FAQ

How to prevent overpressure in the YDZ-1000 tank?

The tank is equipped with a built-in safety valve that automatically releases excess pressure. Never seal the tank mouth, and regularly inspect the safety valve for blockages or malfunctions. Avoid exposing the tank to direct sunlight or high temperatures, which can accelerate liquid nitrogen vaporization.

Can the tank be used for long-distance transport?

Yes, the YDZ-1000 is designed for both storage and transport. Its robust structure, advanced insulation, and braking casters ensure stability during transit. Secure the tank upright during transport and avoid剧烈 collisions to maintain vacuum integrity.

What is the maximum filling capacity?

Do not fill beyond 80%-90% of the total geometric volume (1050L). This leaves space for liquid nitrogen expansion and gas evaporation, preventing pressure buildup and ensuring safe operation.
