Product Description

LDH Small liquid nitrogen machine is a plug-in liquid nitrogen solution. Based on the regenerative multi-component mixing medium throttling refrigeration cycle, the multi-component mixing medium with high, middle and low boiling point is selected to form the multi-component mixing medium from the ambient temperature to the target cooling temperature, and the relay matching of the effective cooling temperature zone of each boiling point component is realized. It is a kind of refrigerator that can efficiently realize the temperature zone of -40~-196ºC.

Working principle:
The compressed air passes through the oil-free air compressor, goes through the cold and dry suction and filtration, enters the PSA nitrogen machine, passes through the bactericidal filter and generates sterile nitrogen with a dew point of -60ºC. Sterile nitrogen enters the refrigerator and liquefies to liquid nitrogen.
Product feature:
Liquid nitrogen output: 10L-120L per day.
Timed start and stop: you can freely set the start and shut down time every day.
Liquid level start and stop: If the liquid nitrogen tank with a liquid level gauge is equipped, the start and stop can be controlled according to the liquid level and the liquid level is displayed.
Remote monitoring: MCGS remote monitoring, remote download of historical operation records, online program upgrade, convenient remote maintenance.
Fully enclosed box type compact design.
Liquid nitrogen dewar bottle (optional).
