For the pharmaceutical enterprises with SKID, storage and distribution of water for injection system can achieve high temperature cycle, normal atmospheric temperature cycle and low temperature cycle and many kinds of operating modes.Using3D modular design to ensure compact , beautiful and generous .The pump ,heat exchanger , valves , pipeline materials required by equipment are used for outstanding international brands , to ensure the quality of the system . The selection of control system hardware is based on the standard module widely used in world . For PLC we use SIEMENS 300 series ,MP277 series of touch screen for HMI . The program design , check and constitute are in conjunction with V-GAMP5 model , the software model is applicable to all the PLC S7 system . The design of program refers to the GAMP5 to optimize the design , improving the stability of the program , and there are relevant documents to support , to ensure the traceability of the system . In order to check whether the purified water system can produced stably in accordance with the quality requirements in a variety of situations that may occur in the future , Joway verify and test the system involving: risk assessment (RA) / design qualification (DQ) / installation qualification (IQ) /operational qualification (OQ). All system meet the requirements of FDA cGMP 、EU GMP、WHO GMP and SFDA GMP .
