Working principle: liquid nitrogen generator (liquid nitrogen machine) equipment consists of nitrogen generator (built-in or external), refrigeration equipment (gas liquefaction equipment) and duwa tank.The whole machine has the function of one-button start automatic rehydration. When the liquid nitrogen in the liquid nitrogen tank is lower than the set liquid level, the equipment will start automatically.Liquid nitrogen machine manufacturing adopts the principle of mixed working mass throttling cooling, nitrogen liquefaction from ambient temperature to saturated condensation temperature, refrigeration minimum temperature to 196, liquid liquid nitrogen to liquid nitrogen storage liquid nitrogen tank, equipment automatic detection of liquid nitrogen in the duwa tank, automatic control equipment operation.
1. The liquefaction system adopts advanced mixed environmentally friendly refrigerant (MR).
2. Refrigerator without regular maintenance, high reliability, long use cycle and other characteristics.
3. All deep cold pipe fittings use vacuum insulation pipe to reduce cooling loss.
4. Touch-type color Chinese and English operation interface.
5. The equipment has the function of automatic rehydration and automatic control system.
