DESCRIPTION FOR GOODS 对供货范围的描述
Centac C90MX5N2 is a unit of single deck configuration, single suction and discharge, five stage 100% oil free centrifugal air compressor driven by an electric motor, The compressor and the motor are coupled by coupling and the entire unit is mounted on a common baseplate with air cooling system, local control system, lube system and auxiliaries. The compressor can be operated and controlled either at the local panel, which is mounted on the compressor base-plate, or at the Operation Control Center “OCC” room in which the relative computer control system is installed as option.
CENTAC C90MX5N2氮气压缩机是一台由电机驱动，单层结构的、单级吸气和排气的五级压
缩并提供100%无油氮气的离心式氮气压缩机。压缩机和电机经由联轴器直接连接，整个机组包括冷却系统、控制系统、油润滑系统及其它辅助设备都安装在一个公共底盘上。 该机不仅可在安装于机组底盘上的就地微机控制柜上进行操作和控制，还可选择与中央控制系统相连。
