characteristics:
◎Stable flow rate, controllable purity, with various auxiliary controls added. The flow rate can be measured and adjusted as needed, and the purity accuracy is controlled within ± 1%;
◎Fully covering the cutting needs of commonly used boards, equipped with up to 7 processing modes;
◎The overall safety factor of the equipment operation is high, and a delay electromagnetic valve is used to protect the impact of air (gas source) on the nitrogen generator, which can effectively adjust the nitrogen production efficiency of the nitrogen generator;
◎There are various safety control instruments such as pressure sensors, gas flow meters, and nitrogen purity analyzers installed on the gas supply pipeline to achieve the safe start stop and alarm functions of the entire nitrogen production equipment. The integration degree of the entire nitrogen production equipment configuration is very high.
