Product Introduction：
A liquid nitrogen freezer is an ultra-low temperature storage system that uses liquid nitrogen (LN₂) to preserve biological samples, cells, tissues, and other sensitive materials at temperatures as low as -196°C (-321°F). These freezers are essential in research laboratories, biobanks, fertility clinics, and pharmaceutical industries for long-term cryopreservation.
Product features：
Safety and reliability: Multiple safety interlocking designs ensure the safety and reliability of operators and production sites.
Sanitation and environmental protection: The machine is manufactured and produced in strict accordance with relevant standards for food machinery. The whole machine adopts a fully welded structure of food-grade 304 stainless steel. The machine body and internal parts are easy to move and clean, which fully complies with the design of sanitary engineering.
High configuration: Adopting low-temperature valves of world-renowned brands, PLC plus touch screen intelligent temperature control, interlayer adopts special low-temperature resistant insulation materials, and friendly human-machine operation interface.
Low energy consumption: The patented design of high-efficiency cold capacity transmission fan can quickly form an ultra-low temperature wind field, improve the utilization rate of cold capacity, and reduce the energy consumption of liquid nitrogen by 30% year-on-year.
Flexible response: The equipment adopts international advanced design technology, easy to operate; fewer moving parts, quick and timely response, and easy maintenance. The equipment occupies a small area, which can fully improve the space utilization rate.
Formula mode: Customized fresh-keeping formulas for different food characteristics, hundreds of fresh-keeping quick-freezing process formulas for food ingredients, to ensure the original quality of frozen food ingredients, consistent.
