The working principle of the oxygen removal machine is molecular separation closed-circuit circulation type, that is, the air in the air conditioning warehouse is extracted through the pipeline, and the oxygen is separated out through the separation tank of the equipment, and then the remaining air is returned to the warehouse. The machine controls automatic operation through the circuit board in the microprocessor. As the equipment adopts double-tank circulating type work, it is characterized by fast oxygen reduction, low noise, maintenance-free, less power consumption, and its energy consumption is only 1/5 of the previous generation of hollow fiber membrane nitrogen making machine, without air compressor, without replacing the filter element, to achieve no maintenance operation, high reliability, is the fifth generation of products in air conditioning equipment.
