‘Zhongsu Hengda’ can help customers select supporting air compressor, under normal circumstances, ‘Zhongsu Hengda’ oxygen generator/nitrogen generator choose supporting screw air compressor. Due to its simple structure and few vulnerable parts, the screw compressor can operate under the condition of large pressure difference or pressure ratio, with low exhaust temperature, insensitive to a large amount of lubricating oil (often referred to as wet stroke) contained in the refrigerant, good gas transmission regulation and forced gas transmission, and the volume flow is almost not affected by the exhaust pressure, It can maintain high efficiency in a wide range and is suitable for a variety of working fluids without any change in the compressor structure. Screw air compressor adopts pre packaged configuration, which only needs a single power connection and compressed air connection, and has a built-in cooling system, which greatly simplifies the installation work.
