LDH Company is proud to introduce the YDZ series of liquid nitrogen tanks-high performance cryogenic containers designed for both storage and transportation of liquid nitrogen. Constructed from high-quality stainless steel, these tanks feature an internal pressurization system that vaporizes a small portion of liquid nitrogen to generate pressure, ensuring efficient discharge of the stored product. The tanks consist of a control structure and main body, with control components including inlet/drain valves, vent valves, pressure-increasing valves, safety valves, liquid level gauges, pressure gauges, and casters. Each model in the series comes standard with four movable universal casters, enhancing ease of use and mobility across various locations.
application scenarios
Laboratory Research: Academic and industrial labs use YDZ tanks to supply liquid nitrogen for cryopreservation of biological samples, cooling of equipment (e.g. NMR spectrometers, vacuum pumps), and cryogenic experiments. The tanks' stable pressure output allows easy filling of smaller Dewars and cryostats in lab settings.
Medical and Biological Storage: Hospitals, clinics, and biobanks utilize YDZ tanks to store and dispense LN2 for freezing biological materials (stem cells, blood products, vaccines, etc.) and for cryosurgery equipment. The self-pressurized design ensures a ready supply of LN2 for filling cryogenic freezers and transport dewars used in medical applications.
Agriculture and Veterinary Science: In livestock breeding and veterinary labs, YDZ tanks provide a convenient LN2 source for cryopreserving semen and embryos. The tanks' mobility and continuous dispensing capability support field operations such as artificial insemination services, where LN2 must be transported and used on-site.
Industrial and Manufacturing: Industries use YDZ series tanks for applications like metal shrink-fitting, cryogenic material testing, and as a local LN2 supply for processes requiring inert atmosphere or rapid cooling. The tanks can be moved around factory floors (thanks to built-in casters) to supply multiple workstations with liquid nitrogen.
Food Processing and Hospitality: YDZ tanks are employed in the food industry for flash-freezing ingredients and creating specialty frozen foods. They are also used in molecular gastronomy for instant freezing of culinary creations. The ability to dispense LN2 on demand makes these tanks useful in commercial kitchens and food labs.
Pharmaceutical and Biotechnology: Pharmaceutical companies and biotech firms use YDZ tanks to maintain cryogenic storage of reagents and samples, and to support processes like cryogenic grinding of materials. The tanks' safety features and stable performance meet the stringent requirements of these industries.
