Application area

Applicable to scientific research laboratories, dermatology, cryosurgery, and non-invasive plastic surgery, etc,

LN2 is an important facility for these places. The Weidejie LN2  machine is equipped with air filtration and nitrogen sterilization filtration to enhance medical use.

Dermatology - cryosurgery to remove skin lesions, skin sags, and moles.

Plastic surgery - Non invasive surgery for removing wrinkles, scars, and burns in plastic surgery.

Fertilization - Frozen embryos in small plates before fertilization.

Industry: Frozen pipe fittings - installation or removal of tight fitting parts on machinery using low-temperature shrinkage method.

Main products:

1. Micro and small integrated (or split type) LN2 generators are used for storing biological samples in hospital laboratories (LABS), university laboratories, and research institute laboratories, as well as conducting physical low-temperature tests on new materials. They provide solutions for refrigeration of IC and SEMI (chip, semiconductor) packaging and testing systems. Engineers conduct on-site installation and debugging to achieve AMS (fully automated) fluid replenishment function

2. Liquefaction of gases, with a minimum temperature of -196 ℃, can liquefy oxygen, nitrogen, argon and other gases, and can also provide supporting services for enterprises producing nitrogen and Oxygen concentrator

3. Low temperature detection cooler; Provide solutions for sensor (SNSR) refrigeration in precision testing equipment for PC and IC (integrated circuits, semiconductors)

4. LN2 condensation chiller (zero evaporation) provides solutions for high-end IC, SEMI (chip, semiconductor) packaging testing equipment sensors (SNSR), and radiation resistant equipment refrigeration.

About storing LN2

1. Due to the limited capacity of the built-in LN2 tank, when the produced LN2 reaches the upper liquid level limit, the equipment will automatically stop producing LN2. Therefore, it is recommended that users can release the LN2 from the device after filling it up and store it in an external Dewar tank.

2. If the equipment is powered off and shut down, the pressure of the built-in LN2 tank will gradually increase. When the pressure reaches the upper limit of the internal safety valve, it will automatically relieve pressure, leading to an increase in the amount of LN2 volatilization. Therefore, it is recommended that users save the LN2 in the device to an external LN2 tank before powering off and shutting down.
