1. Low energy consumption of equipment

Full load nitrogen production per hour, with a total energy consumption of less than 39kw/h.

       2. Stable flow rate and controllable purity

The airflow is stable, and nitrogen can reach equilibrium pressure after being stored in the gas storage tank

Purity is controllable, and the nitrogen production process is controlled by the PSA operating program with various auxiliary controls added. The flow rate can be measured and adjusted as needed, and the purity accuracy is controlled within ± 1%.

Product model XRFD-0100S:

When the purity is set at 90%, the flow rate is about 100Nm3/h;
   When the purity is set at 95%, the flow rate is about 60Nm3/h;
   When the purity is set at 99%, the flow rate is about 30Nm3/h; 
   When the purity is set at 99.9%, the flow rate is about 10Nm3/h;
3.Fully covering the cutting needs of commonly used boards, equipped with up to 7 working modes
