INJ-1002(Dual)

INJ-1002(Dual) Maximum 5 (Five) Pumps Control Configuration ( 2 VFDs + 3 DOL Pumps ) This system using 2 (Two) VFDs is expecting higher energy saving effect than our model INJ-1000. Water hammering impact can be prevented by the variable speed operation of two pumps with accurate PID control function. As two variable speed pumps are adjusting together at the same time, minimize the pressure deviation at the alternation and sequence operation of pump so that it maintains a stable pressure and improve further reliability of the system. Various control functions: Constant Pressure Control, Heating Circulation Control, Differential Pressure Control and Temperature Control. User friendly graphic interface of the LCD Touch Screen (240 x 64 dots) is able to confirm and monitor each pump operation status and alarms easily. Easy to confirm the system conditions and the status due to auto saving function of alarms and operating data. Therefore, simple maintenance is possible. The Central Monitoring System (Building Management System) support: Rs-485 (Local) and Modem (Remote). Real-time Internet monitoring services via TCP/IP module (Internet/SMS/Mobile Devices- ipad, Smart Phone). The fastest A/S is able to be realized.
