FAQ
Q: Does the equipment require a dedicated person to be on duty during operation?
A: No, there is no need for a dedicated person. The equipment supports automatic start/stop, automatic liquid level control and fault alarm functions. The operating status can be remotely monitored, and notifications will be sent promptly in case of abnormalities.
Q: Can the nitrogen purity meet the requirements of the semiconductor industry?
A: The default purity is 99.9%-99.995%, and a high-purity version of 99.999% can be customized. It fully meets the requirements of precise scenarios such as semiconductor manufacturing and laser cooling.
Q: How long can the liquid nitrogen with the built-in Dewar flask be stored?
A: Using vacuum insulation technology, it can maintain for 7-10 days during static storage. During daily use, the equipment will automatically replenish production based on the liquid level, so there is no need to worry about supply interruption.
Q: What are the main technical types of nitrogen generators?
There are two mainstream technologies:
PSA (Pressure Swing Adsorption) nitrogen generator: It utilizes the difference in adsorption between oxygen and nitrogen by applying pressure for adsorption and reducing pressure for desorption, suitable for medium to high purity requirements (95% - 99.999%).
Membrane separation nitrogen generator: It uses hollow fiber membranes to separate gases based on their different permeation rates. The structure is simpler, with a purity typically ranging from 95% to 99.5%, suitable for low purity and small flow scenarios.
Q: Is the equipment energy consumption high?
A: The main energy consumption comes from the accompanying air compressor. Choosing an efficient air compressor, optimizing the system design, and achieving reasonable flow matching are the key to reducing the overall energy consumption. The equipment itself (control system, valves) consumes very little electricity.
Choosing a nitrogen filling and nitrogen generation machine for food preservation is choosing a safe, economical and efficient preservation solution for your products.
