Self-Pressurizing Liquid Nitrogen Tank YDZ-10

| Product Overview

The YDZ-10 Liquid Nitrogen Tank is a premium self-pressurizing cryogenic container engineered by Sichuan Zhonghuo Cryogenic Equipment Co., Ltd. With an effective capacity of 10L, overall dimensions of 355×700mm, and a working pressure of ≤0.1Mpa, this tank leverages the vaporization of a small amount of internal liquid nitrogen (LIN) to generate pressure, enabling automatic liquid discharge. It integrates reliable cryogenic storage and efficient liquid nitrogen replenishment functions, making it a versatile tool for preserving biological samples, supplying cold sources, and supporting industrial processes. Equipped with optional remote monitoring terminals and software, it realizes real-time tracking of liquid level and pressure, along with remote alarms and control, setting a new standard for convenience in low-temperature applications.

| Core Advantages

Integrated Storage & Supply Efficiency

Eliminates the need for manual pouring or external pumps through an internal self-pressurization system. The automatic discharge design allows single-person operation, significantly reducing labor costs and improving workflow efficiency. With a daily evaporation rate of only 7% and a flow rate of ≥2L/Min, it ensures stable and continuous liquid nitrogen supply for extended periods.

Superior Insulation & Durability

Features a high-vacuum insulation structure with inner and outer tanks crafted from high-quality austenitic stainless steel. This design minimizes cold loss, extending the storage life of liquid nitrogen and protecting valuable samples or materials. The robust construction withstands harsh working environments, ensuring long-term reliability in industrial and laboratory settings.

Flexible Configuration & Safety Assurance

Comes with essential safety components including a pressure gauge, safety valve, and vacuum nozzle. Can be equipped with a low-temperature regulator and remote monitoring system for customized needs. Braking casters at the bottom enable easy movement, making it suitable for use in laboratories, workshops, and other confined spaces. Complies with ISO9001 quality standards, guaranteeing strict adherence to safety and performance requirements.

| Types of Products

| Application Fields

Biomedical Preservation

Ideal for the long-term preservation of vaccines, cells, bacteria, viruses, animal organs, human stem cells, blood, and skin. The -196°C deep cryogenic environment maintains biological activity, supporting research, clinical trials, and regenerative medicine advancements.

Industrial & Manufacturing Processes

Widely used in the mold industry for cryogenic treatment, metal manufacturing for enhancing material hardness and wear resistance, and semiconductor production for precise temperature control. Serves as a stable cold source for laboratory equipment like freeze dryers in food processing and low-temperature chemical reactions.

Animal Husbandry & Agricultural Science

Facilitates the long-term active preservation and long-distance transportation of semen from valuable breeding stock (cattle, sheep) and rare animals. Provides critical technical support for artificial insemination and genetic improvement programs, boosting breeding efficiency and quality.

| Operation & Safety Guidelines

Pre-Operation Preparation

Inspect the tank shell for dents, cracks, and ensure the vacuum exhaust port is intact. Verify the interior is clean, dry, and free of foreign objects.

Check accessories: Ensure lifting baskets and canes are not deformed; confirm level gauge markings are clear (if equipped).

Pre-cool new or idle tanks: Slowly inject 1/10 of the total capacity of liquid nitrogen, wait for boiling to subside, and then fill completely.

Safe Filling & Usage

Wear full Personal Protective Equipment (PPE): Cryogenic gloves, safety goggles/face shield, long-sleeved lab coat, and ankle-covering pants.

Fill slowly using a dedicated funnel, pouring along the inner wall to avoid splashing. Do not fill beyond 80%-90% of capacity to leave space for expansion.

Minimize lid-open time (≤30 seconds per access) to reduce nitrogen loss and temperature fluctuation. Handle samples gently with baskets to avoid collisions.

Post-Operation Maintenance

Clean the exterior with a dry, soft cloth. For long-term storage, empty the tank, let it warm to room temperature, rinse the liner with 40-50°C warm water, and air dry completely.

Conduct monthly inspections: Check neck plug seals and accessories for damage; log nitrogen usage. Address abnormal frost on the outer shell promptly.

Store the tank upright in a cool, dry, and well-ventilated area, away from confined spaces to prevent oxygen deficiency.

| Production Process

The YDZ-10 Liquid Nitrogen Tank undergoes a rigorous manufacturing process to ensure premium quality. It starts with the selection of high-grade austenitic stainless steel for the inner and outer tanks, followed by precision cutting and forming using advanced CNC equipment. The high-vacuum insulation layer is created through professional vacuum pumping technology to achieve optimal thermal insulation performance. Safety components such as pressure gauges (certified by Hongqi Instruments) and safety valves are installed and calibrated to meet strict standards. Each tank undergoes hydrostatic testing, airtightness testing, and cryogenic performance verification before leaving the factory. Compliant with GB/T19001-2016/ISO9001:2015 quality management systems, every unit is accompanied by a product quality inspection certificate.

| FAQ

Can the YDZ-10 Liquid Nitrogen Tank explode?

Liquid nitrogen itself is non-flammable and non-explosive. However, if the tank is hermetically sealed or the pressure relief valve fails, vaporized nitrogen (expanding 700× its original volume) can cause pressure buildup and rupture. Always use certified containers with functional pressure relief devices and never seal the tank mouth.

How to handle skin contact with liquid nitrogen?

Liquid nitrogen’s ultra-low temperature (-196°C) can cause severe cold burns/frostbite. Immediately rinse the affected area with warm water (not hot) and seek medical attention if burns are severe. Always wear proper PPE during operation.

Can the tank be used for long-distance transportation?

Yes. The YDZ-10 is designed for both storage and transportation of liquid nitrogen. Its robust structure, secure sealing, and low evaporation rate ensure safe and efficient transport of biological samples or liquid nitrogen to remote locations.
