A wide range of laboratory instruments require the use of liquid nitrogen for cooling and sample storage, biological sample banks, medical cold storage, scientific research laboratories and other high-end fields.

We offer self-pressurized liquid nitrogen refill tanks, YDZ-15 to YDZ-500 liters, 175 liters preferred for laboratories and superconductors!

175 liter self-pressurized liquid nitrogen tanks, equipped with multi-stage safety system, including double safety valves, pressure stabilization facilities;

Drain valve, vent valve, pressurization valve, easy to operate continuous and stable replenishment of liquid nitrogen, IVF sample banks, sperm banks, stem cell banks as a fluid supply, as well as laboratories with large-capacity liquid nitrogen tanks, superconductors to use and so on.

Product highlights:

Ultra-large capacity storage: provide sufficient liquid nitrogen reserve for large sample banks,;

Self-pressurizing design: using the pressure generated by the vaporization of liquid nitrogen in the tank, the liquid nitrogen is automatically discharged safely and environmentally friendly, without additional power energy consumption, to ensure a continuous and stable supply of liquid nitrogen, with a stable working pressure of less than 0.09Mpa;

Safety technology: adopting double safety valve design to provide you with double safety protection measures; it can be equipped with low-temperature solenoid valve to realize full-automatic liquid replenishment;

Daily evaporation loss rate: adopting unique vacuum technology to ensure the long time preservation of liquid nitrogen;

Humanized caster design: equipped with high load moving casters, quick and convenient to move;

Production process: all welds are qualified by helium mass spectrometer leakage detection and 100% low-temperature rigorous testing to ensure the reliability of the product;

Production materials: made of high quality 304 low temperature resistant stainless steel.
