A membrane nitrogen plant is a set of special equipment designed to produce nitrogen from atmospheric air by the method of membrane separation at a pressure of up to 25 bar. The production of nitrogen in this technological process is based on the principle of separation of gas mixtures in a membrane module, due to the different penetration rates of the components of the gas mixture through polymer membranes and the differential partial pressures on both sides. In the case of separation of the air mixture, oxygen has a greater permeability than nitrogen. The difficult-to-penetrate gas components (N2, CH4, CO) pass along the entire length of the generator and then come to the consumer. The output is a gas mixture with an N2 content of up to 99.9%. The membrane installation allows to obtain high-pressure production gas (nitrogen). The composition of a standard membrane nitrogen production plant: Air compressor; Dehumidifier; Main filter block, including coal column; Air receiver; Membrane generator; Production gas receiver.

The optical parameters of the media converter are determined by the parameters of the SFP modules installed in the corresponding slot of the media converter. The media converter supports working with various SFP modules with a supply voltage of 3.3 V and a data transfer rate of up to 1250 Mbit/s, that allows you to organize data transmission at distances from 0.5 to 120 km, both over multimode and single-mode fiber in two- or single-fiber communication lines. The analogue of this media converter for the SFP module is Planet GT-805A.
