Nitrogen liquefier (Refrigerator)

The liquid nitrogen generator (liquid nitrogen machine) is composed of three parts: nitrogen generator (built-in or external), refrigeration equipment (gas liquefaction equipment) and Dewar tank. The whole machine has the function of automatic liquid replenishment with one key, and the equipment starts automatically when the liquid nitrogen in the liquid nitrogen tank is lower than the set liquid level. Liquid nitrogen machine manufacturing adopts the principle of mixed mass throttling refrigeration, cooling nitrogen from the ambient temperature to the saturation condensing temperature of nitrogen liquefaction step by step, the lowest temperature of refrigeration machine refrigeration can be up to -196 °, the liquid nitrogen liquefied in the refrigeration evaporator is transported to the liquid nitrogen tank to save the liquid nitrogen to obtain liquid nitrogen, the equipment automatically detects the liquid nitrogen level in the Dewar tank, and fully automatic control of the operation of the equipment.  

One-button power-on, fully automatic rehydration! The small integrated liquid nitrogen machine is an ideal choice for your laboratory. Using advanced mixed environmentally friendly refrigerants, our liquid nitrogen machine can cool nitrogen to a liquefied state step by step, and the refrigeration temperature can reach as low as -196°C. The equipment has a one-button start-up automatic liquid replenishment function, which will automatically start when the liquid nitrogen tank is lower than the set liquid level. The product operation interface adopts touch-type color Chinese and English interface, which is convenient for operation. In addition, all cryogenic pipes use vacuum insulated pipes to reduce cold loss and provide efficient refrigeration performance. Choose our products, you will get the advantages of automatic control, environmental protection, energy saving and convenient operation.

Our laboratory small liquid nitrogen machine adopts advanced cold head refrigeration technology, which can reliably freeze dry nitrogen to a low temperature of -196°C. The equipment has various alarm protection functions to ensure safety and reliability during use. In addition, our products do not require regular maintenance and have a long service life, providing laboratories with high reliability and long-term stable operation solutions. The appearance of the product is beautiful and durable, and it adopts advanced manufacturing technology, which has the advantages of safety, quietness, convenience, energy saving and intelligent environmental protection.

The air enters the air compressor after removing dust and mechanical impurities through the air filter, compressing to the required pressure, and outputting clean compressed air after strict purification treatment of oil, water and dust removal, with the purpose of ensuring the service life of the molecular sieve in the adsorption tower. There are two adsorption towers with carbon molecular sieves, one tower works while the other tower is decompressed and desorbed. The clean air enters the working adsorption tower, passing through the molecular sieve when oxygen, carbon dioxide and water are adsorbed by it, the gas flowing to the exit end is nitrogen and trace amounts of argon and oxygen. Another tower (desorption tower) so that the adsorbed oxygen, carbon dioxide and water from the molecular sieve pores out of the discharge to the atmosphere. In this way, the two towers take turns to complete the separation of nitrogen and oxygen, continuous output of nitrogen, variable pressure (_bian4 ya1) adsorption nitrogen purity of 95%-99.9%, if you need a higher purity of nitrogen need to increase the nitrogen purification equipment. Variable pressure adsorption nitrogen machine output of 95%-99.9% nitrogen into the nitrogen purification equipment, while adding the appropriate amount of hydrogen through a flow meter, in the purification equipment in the oxygen removal tower hydrogen and nitrogen in the trace oxygen catalytic reaction to remove oxygen and then cooled by the water condenser, vapor separator to remove water, and then through the dryer depth drying removal.
