Twenty-first Century is the era of biotechnology, nanotechnology and electronic information technology. Medicinal high purity nitrogen machine is mainly used in pharmaceutical raw materials, pharmaceutical packaging, nitrogen transport and protection; western medicine injection nitrogen filling, storage tank and container filled with nitrogen gas, spices pneumatic transmission etc..

The demand for nitrogen is very high. The high purity nitrogen making machine must meet the following requirements:

1, require high purity nitrogen, general requirements of 99% ~ 99.99%;

2, free of dust and nitrogen requirements for heat source, injection filling;

3, nitrogen production function in the production process to maintain the constant pressure of nitrogen supply, as well as to ensure the normal operation of production.
