Product Description

Compact All - in - One Liquid Nitrogen Machine: Your Efficient and Convenient Cryogenic Solution


In numerous fields that demand a cryogenic environment, the compact all - in - one liquid nitrogen machine plays an indispensable role with its unique advantages. The compact all - in - one liquid nitrogen machine meticulously crafted by Beijing LDH Technology Development Co., Ltd. stands out as a top - tier product in this realm.

 

Company's Strengths as a Backing

Beijing LDH Technology Development Co., Ltd. is a high - tech enterprise specializing in the research, development, production, sales, and service of gas equipment and cryogenic application equipment. The company holds multiple national patents and computer software copyright certificates. It has also passed the EU CE certification and ISO9001 certification, ensuring a solid guarantee in technological innovation and product quality. With extensive cooperation with domestic and foreign research institutions, the company constantly absorbs advanced technologies, keeping its products at the forefront of the industry. This lays a solid foundation for the excellent quality of the compact all - in - one liquid nitrogen machine.

 

Working Principle Analysis

The compact all - in - one liquid nitrogen machine adopts the advanced Mixed Refrigerant Joule - Thomson (MRJT) process, operating based on the regenerative multi - component mixed - refrigerant throttling refrigeration cycle. From the ambient temperature to the target refrigeration temperature, it carefully selects pure components with high, medium, and low boiling points to form a multi - component mixed refrigerant. These components with different boiling points function like relay runners, each playing its part within its effective refrigeration temperature range, enabling efficient refrigeration from ambient temperature to the - 40~ - 196°C temperature range and successfully liquefying nitrogen in the air into liquid nitrogen.

 

During this process, the compressed air is first processed by an oil - free air compressor, then passes through cold - drying, adsorption - drying filtration, a PSA nitrogen - making machine, and finally, through a sterilizing filter to generate sterile nitrogen with a dew point of - 60°C. This sterile nitrogen is then liquefied into liquid nitrogen after entering the refrigerator.

 

Product Feature Highlights

1. Flexible and Diverse Output

The liquid nitrogen output ranges from 10L - 120L per day. For example, the LPLN - 10 model has an output of 0.3 - 0.4L/H (8 - 10L/day), and the LPLN - 120 model can reach 5L/H (120L/day). It can meet the needs of different users, whether it is a small - scale laboratory with a limited demand for liquid nitrogen or a small - scale enterprise with a medium - sized usage requirement.

2. Intelligent Start - Stop Control

It supports the timer start - stop function, allowing users to freely set the daily start and stop times according to actual needs, effectively saving energy. When equipped with a liquid nitrogen tank with a liquid - level gauge, it can also achieve liquid - level - controlled start - stop. The equipment will automatically control its operation based on the liquid - level in the liquid nitrogen tank and display the liquid - level in real - time, enabling users to keep track of the liquid nitrogen reserve at any time.

3. Convenient Remote Monitoring

Equipped with the MCGS remote monitoring system, users can remotely download historical operation records to understand the equipment's operating status and perform online program upgrades for convenient remote maintenance. Even if you are in a different location, you can have a clear understanding of the equipment and handle potential problems promptly.

4. Compact and Practical Design

It features a fully enclosed box - type compact design, occupying a small area. Taking the LPLN - 10 as an example, the equipment size is only 750*850*1700mm, with a footprint of 1m², and it only requires a room area of more than 5m². It has low requirements for the installation site, making it suitable for use in places with limited space. Additionally, a liquid nitrogen Dewar flask can be optionally configured, providing more convenience for liquid nitrogen storage.

 

Wide Range of Application Fields

1. Biological Sample Preservation

In the field of biological research, the cryogenic preservation of biological samples such as cells, tissues, and embryos is of utmost importance. The ultra - low - temperature environment provided by the compact all - in - one liquid nitrogen machine can preserve biological samples at - 196°C for a long time. This effectively inhibits microbial growth and chemical reactions, maintaining the biological activity of the samples and providing strong support for biomedical research, gene bank construction, and other fields. It plays an irreplaceable role in stem cell transplantation, umbilical cord blood cryopreservation, and other aspects.

2. Medical Applications

In the medical field, liquid nitrogen is commonly used for cryotherapy. The compact all - in - one liquid nitrogen machine supplies liquid nitrogen for cryotherapy equipment. Through the ultra - low temperature of liquid nitrogen, diseased tissues are frozen and necrotic, achieving the purpose of treatment. It can be used to treat various diseases such as corns, warts, and skin diseases. For athletes' recovery treatment, liquid nitrogen cryotherapy chambers also require liquid nitrogen as a cold source, and the compact all - in - one liquid nitrogen machine can stably supply liquid nitrogen to meet the treatment needs.

3. Assistance in the Food Industry

In the food industry, the liquid nitrogen quick - freezing technology is widely used due to its unique advantages. The compact all - in - one liquid nitrogen machine can provide liquid nitrogen for food quick - freezing. Liquid nitrogen quick - freezing features a fast freezing rate, the ability to maintain food quality, and low material dry - loss. It can enable food to quickly pass through the 0°C - 5°C maximum ice - crystal growth zone, maximizing the retention of the color, aroma, taste, and nutritional components of the food. It plays a crucial role in the quick - freezing and preservation of fruits, vegetables, meats, aquatic products, and other foods.

4. Guarantee for Scientific Research Experiments

In scientific research experiments, many experiments require an extremely low - temperature environment to simulate special conditions or conduct material processing. The compact all - in - one liquid nitrogen machine can provide liquid nitrogen for equipment such as nuclear magnetic resonance spectrometers, ensuring the stable operation of superconducting magnets and providing a guarantee for researchers to obtain accurate experimental data. In materials science research, it can also be used for experimental tests of material properties at low temperatures.

The compact all - in - one liquid nitrogen machine of Beijing LDH provides an efficient and convenient cryogenic solution for numerous industries with its advanced technology, reliable performance, and wide range of applications. If you have relevant needs, this product could be your ideal choice to start a new experience of efficient cryogenic applications.
