Compact Self-pressurized Liquid Nitrogen Tank YDZ-15

| Product Overview

The YDZ-15 Self-Pressurized Liquid Nitrogen Tank is a compact, high-performance cryogenic solution from Zhonghuo, tailored for small-scale storage, transportation, and liquid nitrogen supplementation. With an effective capacity of 15L (geometric volume 16.5L), it features overall dimensions of 355×750MM, a net weight of 21KG, and a full weight of 33KG, making it highly portable. Operating at ≤0.1Mpa working pressure, it has a daily evaporation rate of 7% and a flow rate of ≥2L/Min, ensuring consistent cryogenic performance. Constructed with high-quality austenitic stainless steel inner and outer tanks and a high-vacuum insulation layer, the YDZ-15 maintains a stable -196°C environment, perfect for laboratories, small production facilities, and on-site cryogenic applications across various industries.

| Core Advantages

Compact Design & Easy Mobility

The tank’s space-saving 355×750MM dimensions and 21KG net weight make it ideal for limited spaces like laboratories. Equipped with braking casters, it offers flexible and stable movement, allowing easy relocation within workspaces without heavy lifting.

Efficient Self-Pressurization System

The internal self-pressurization mechanism vaporizes a small amount of liquid nitrogen to generate pressure, enabling automatic liquid discharge. This eliminates the need for manual pouring or external pumps, supporting single-person operation and significantly improving work efficiency for small-scale tasks.

Enhanced Insulation & Long Storage Life

The high-vacuum insulation structure, combined with austenitic stainless steel construction, effectively reduces liquid nitrogen evaporation loss. Even with a 7% daily loss rate, the YDZ-15 ensures extended storage duration, minimizing frequent refilling and operational costs.

Versatile Configuration & Smart Upgrades

Compatible with low-temperature voltage regulators and liquid nitrogen tank monitoring systems, the tank supports remote data transmission (liquid level, pressure), remote alarms, and manual remote control of pressurization and replenishment. It integrates seamlessly with laboratory equipment like freeze dryers, providing a stable cold source.

| Application Fields

Laboratory & Biomedical Research

Perfect for storing small batches of biological samples (cells, bacteria, viruses, blood, stem cells) in academic and industrial laboratories. The -196°C environment preserves biological activity, supporting experiments, sample banking, and research projects.

Small-Scale Manufacturing & Processing

Used in small-batch metal precision machining for cryogenic treatment, enhancing material performance. Suitable for mold industry, semiconductor workshops, and low-temperature chemical labs, providing localized cryogenic support.

Veterinary & Animal Husbandry

Ideal for small-scale breeding facilities to store semen of livestock (cattle, sheep) and rare animals, facilitating on-site artificial insemination and breeding program implementation.

Food & Pharmaceutical Small-Batch Processing

Applied in food freezing, pharmaceutical low-temperature storage, and vaccine preservation for small-scale production or clinics, ensuring product quality and safety.

| Operation & Safety Guidelines

Pre-Operation Checks

Tank & Accessory Inspection: Examine the shell for damage, ensure vacuum exhaust port integrity, and check that lifting baskets, canes, and pressure gauges are functional.

Pre-Cooling: For new or idle tanks, add 1/10 capacity liquid nitrogen slowly to pre-cool the inner tank. Wait for boiling to stop and liquid to stabilize before full filling.

Safe Handling & Filling

Wear mandatory PPE: cryogenic-resistant gloves, safety goggles/face shield, long-sleeved lab coat, and pants covering ankles.

Avoid confined spaces; operate in well-ventilated areas to prevent nitrogen gas buildup and oxygen depletion.

Use a dedicated transfer tool to pour liquid nitrogen along the inner wall slowly, avoiding splashing and overfilling (max 80%-90% capacity).

Maintenance & Storage

Monitor liquid level regularly via dipstick or weighing; replenish when level drops below 30% to protect stored samples.

Keep lid opening time under 30 seconds during sample access; handle samples gently with baskets to avoid neck tube collisions.

Store the tank upright in a cool, dry, well-ventilated location. Clean the exterior with a dry cloth; for long-term idle storage, rinse the inner liner with warm water and air dry completely.

Conduct monthly checks on seals, valves, and casters; address any frost accumulation or equipment malfunctions immediately.

| Production Process

The YDZ-15 is manufactured through a precision-focused process adhering to ISO9001:2015 and GB/T19001-2016 standards. High-grade austenitic stainless steel is cut and welded to form the inner and outer tanks, ensuring structural durability. The interlayer is wrapped with multi-layer insulation materials and subjected to high-vacuum processing to achieve superior thermal insulation. Key components, including Hongqi pressure gauges (calibrated to 0.1-0.4Mpa) and safety valves, are installed and tested for pressure resistance and reliability. Each tank undergoes strict quality inspections, including evaporation rate testing, vacuum tightness checks, and leak detection. The production line is overseen by experienced technicians, with third-party certification to guarantee consistent performance and safety.

| FAQ

Is the YDZ-15 suitable for laboratory use?

Yes! Its compact size (355×750MM), lightweight (21KG net weight), and braking casters make it perfect for laboratory spaces. The automatic liquid discharge function and stable -196°C environment support sample storage and equipment cold source supply.

How to prevent cold burns during operation?

Liquid nitrogen’s extremely low temperature (-196°C) poses cold burn risks. Always wear cryogenic-resistant gloves, safety goggles/face shield, and full-body protective clothing. Avoid direct skin contact with liquid nitrogen or cold tank surfaces.

Can the YDZ-15 be connected to monitoring systems?

Absolutely. The tank can be equipped with a liquid nitrogen tank monitoring terminal and software, enabling remote transmission of liquid level, pressure data, low liquid level/overpressure alarms, and remote control of pressurization and liquid replenishment, enhancing operational convenience.
