Efficient Self-pressurized Liquid Nitrogen Tank YDZ-200

| Product Overview

The YDZ-200 Liquid Nitrogen Tank is a premium self-pressurizing cryogenic container engineered by Zhonghuo, designed for reliable storage and transportation of liquid nitrogen (LIN). With an effective capacity of 200L and geometric volume of 210L, this tank boasts overall dimensions of 706×1350MM, a net weight of 105KG, and a full weight of 265KG. Operating at a maximum pressure of ≤0.1Mpa, it features a low daily evaporation rate of 1.10% and a flow rate of ≥8L/Min, ensuring minimal liquid nitrogen loss during long-term use. Crafted with high-quality austenitic stainless steel for the inner liner and outer tube, paired with a multi-layer insulation vacuum interlayer, the tank maintains the ultra-low temperature of -196°C required for cryogenic preservation. Equipped with essential components like a pressure gauge, safety valve, liquidometer, and mobile casters, it integrates functionality and mobility, making it a versatile choice for various industrial and laboratory applications.

| Core Advantages

Integrated Storage & Transport Efficiency

The YDZ-200 eliminates the need for manual pouring or external pumps through its built-in self-pressurization system. By vaporizing a small amount of liquid nitrogen to generate pressure, the tank enables automatic discharge, allowing single-person operation and significantly boosting workflow efficiency. Whether for on-site liquid nitrogen replenishment or long-distance transport, this all-in-one design streamlines operations and reduces labor costs.

Superior Insulation & Durability

Featuring a high-vacuum insulation structure, the tank minimizes daily evaporation loss, extending the storage duration of liquid nitrogen. The use of corrosion-resistant austenitic stainless steel ensures structural integrity even in harsh low-temperature environments, while the reinforced vacuum cover and sorbent enhance thermal insulation performance. This durability translates to long service life and consistent performance in demanding applications.

Flexible Mobility & Customization

Equipped with braking casters at the bottom, the YDZ-200 Liquid Nitrogen Tank offers smooth and stable movement within laboratories, factories, or medical facilities. It can be optionally fitted with a liquid nitrogen tank monitoring terminal and software, enabling remote transmission of liquid level, pressure data, and real-time alerts for low liquid levels or overpressure. Additionally, customizable accessories like low-temperature voltage regulators cater to specific user requirements.

| Operation & Safety Guidelines

Pre-Operation Preparation

Tank Inspection: Check the shell for dents or cracks, ensure the vacuum exhaust port is intact, and verify the interior is clean, dry, and free of foreign objects.

Accessory Check: Confirm lifting baskets and canes are undamaged, and the liquidometer (if equipped) has clear markings.

Pre-Cooling: For new or long-unused tanks, slowly inject 1/10 of the total capacity of liquid nitrogen for pre-cooling. Wait until boiling subsides before full filling.

Safe Filling Procedures

Wear cryogenic-resistant gloves (cotton gloves prohibited), safety goggles, a long-sleeved lab coat, and pants covering ankles.

Operate in a well-ventilated area to avoid oxygen deficiency from nitrogen gas accumulation.

Use a dedicated funnel to pour liquid nitrogen slowly along the inner wall, controlling flow rate to prevent splashing. Do not fill beyond 80%-90% of total capacity.

Sample Access & Maintenance

Keep the lid open for ≤30 seconds per access to minimize nitrogen loss and temperature fluctuation.

Use baskets to handle samples gently, avoiding collisions with the neck tube. Allow residual liquid nitrogen to drip off after removal.

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

| FAQ

Is the YDZ-200 Liquid Nitrogen Tank prone to explosion?

Liquid nitrogen itself is non-flammable and non-explosive. However, rupture may occur if the tank is hermetically sealed or the pressure relief valve fails, as liquid nitrogen vaporizes to 700 times its volume. Always use certified containers with functional pressure relief devices and never seal the tank mouth.

How to protect against cold-related injuries?

Liquid nitrogen’s -196°C temperature can cause severe frostbite. Always wear personal protective equipment (PPE) including cryogenic gloves, face shields, long-sleeved coats, and ankle-covering pants. Avoid direct skin contact with the tank’s cold surfaces or splashed liquid nitrogen.

When should liquid nitrogen be replenished?

Monitor the liquid level regularly using a dipstick or weighing method. Replenish when the level drops below 30% or before stored samples are exposed to prevent temperature rise and sample damage.
