Next Generation PLC Controls Boost Performance of Polymer Melt Filters
Operational parameters are configured via an automation algorithm that detects real-time processing conditions. The rate of filter screen advancement is continuously monitored and automatically adjusted according to pressure conditions to maintain constant processing pressure and melt temperature.
High-Technology Corp. latest generation of PLC touchscreen controls has descriptive graphics and enables maximum flexibility to adapt to varying processing conditions. Both operational parameters and hardware are continuously monitored with 19 discrete alarms that can be integrated into the operation of the line.
Operational parameters are configured via an automation algorithm that detects real-time processing conditions and adjusts the operation of the screen changer accordingly. Configuration of operational parameters is completed via multi-layer password protection. Constant processing pressure is automatically maintained with the highest level of automation by adjusting screen displacement according to pressure conditions.
High-Technology’s latest Model DRXL screen changer introduces several new features including a proprietary flow-channel and breaker plate geometry to form a balanced polymer seal for consistent screen displacement. Outstanding results have been achieved in a wide range of challenging applications including flexible PVC precision tubing as well as co-ex cast film lines running highly filled polymers requiring ultra-fine filtration.
