YDZ Self-Pressurized Liquid Nitrogen Tank

Product Overview

The YDZ self-pressurizing liquid nitrogen container is a professional cryogenic storage and delivery system that combines low-temperature storage with stable liquid nitrogen supply. It is designed for applications that require continuous LN₂ output and precise pressure control.

The container is manufactured from high-quality stainless steel, offering excellent durability, corrosion resistance, and reliable performance under extreme low-temperature conditions.

Equipped with a built-in pressurization system, the unit can automatically generate pressure and discharge liquid nitrogen without the need for an external gas source. This ensures convenient operation, high efficiency, and dependable performance.

The system consists of a storage vessel and an integrated control assembly. The control components include:

• Liquid inlet and outlet valves
• Vent valve
• Pressure-building valve
• Safety valve
• Level gauge
• Pressure gauge
• Heavy-duty swivel casters for easy mobility

This configuration allows flexible operation across various working environments.

Working Principle

The system operates based on the natural vaporization of cryogenic liquid.

A small amount of liquid nitrogen flows into a pressure-building coil, where it absorbs ambient heat and vaporizes into nitrogen gas. This process creates internal pressure inside the container.

The generated pressure then pushes the stored liquid nitrogen through the discharge line, ensuring continuous and stable delivery.

The pressure-building valve and control structure allow users to adjust and maintain the desired output pressure.

For safety, the system is equipped with a safety valve and vent valve to automatically release excess pressure under abnormal conditions, ensuring safe and reliable operation.
