Flygt - Geared Adaptive Mixers - 4320

Product Features:

• High-efficiency permanent magnet IE4 equivalent motor
• Integrated power electronics based on the Flygt Dirigo technology that eliminate the need for external Variable Frequency Drives (VFD)
• Large diameter propeller (up to 2,5 m ) with backswept self-cleaning design
• Geared and adjustable output ( thrust ) with speed up 70 rpm
• Scalable mixer control system with flexibility to match different process scenarios
• Tank-side or remote control by using FPG 415 gateway with analog I/O and fieldbuses ( ADF-system )
• Automated control for oxidation ditch processes by using pre-engineered controller APP 412 with analog I/O and fieldbuses ( ADC-system )
• Full status and alarms information for flexible or automated control ( ADF and ADC-system) by using jog wheel operator panel FOP 315 or touch screen operator panel FOP 402
• Multiple mixer control with APP 412 ( ADC system )
• Easy to upgrade to flexible- or automated mixer control (ADF or ADC system). The mixer is always the same independent of control system.
• Consistenly correct propeller rotation
• Soft start and stop
• Automatic overload protection
• Power factor close to 1

Spend up to 50% less on energy

Whether you operate Flygt 4320 with full automation or manage it from the tank-side or your control room, it provides market leading mixing efficiency with significant energy savings. By continuously matching output to real process demand without compromising mixing efficiency, it generates up to 50 % in energy savings and lower the overall operational cost.

Improve Process Resiliency

Customers will experience full and immediate flexibility with Flygt 4320. With manual tank side control or automated SCADA-integrated control, you can be sure that the mixer can adapt to handle unexpected and planned changes with maintained efficiency. During infrequent events like seasonal fluctuations, tank cleanings, plant upgrades or automated control in oxidation ditches, the user-friendly Flygt operator panel (FOP) puts you in complete control of your mixer’s output so you can react quickly and efficiently.

Different control systems are available to match different process scenarios:

• AD - Standard control system
• Pre-set control with fixed speed that incorporates many built-in valuables features providing high energy savings, key autonomous protection and scalability for easy upgrade to flexible control or automated control (ADF-or ADC system ) at a later stage.

• ADF - Flexible control system
• Gear up your Flygt 4320 for tank-side and remote operations by adding the FPG 415 gateway with analog I/O and fieldbuses.  The fully integrated monitoring functions provide ease of connectivity and connections to the operator panel assuring optimal mixer operation.
• ADC - Automated control system
  • Set-point speed control set mixer speed as a function of whether an aeration system is on or off.
  • Flow meter control for variable speed aeration sets the mixer speed as a function of an aeration system’s airflow via an air flow meter.
  • Fully automated sensor less torque based control with propeller speed that is adjusted automatically. Patented solution.
• A complete pre-engineered and optimized package by adding APP 412 controller for oxidation ditch process control and multiple mixer operations. Available with different functionalities:

Increase Mixer Uptime

• The control electronics in 4320 are placed inside a dust-free, non-oxidixing environment reducing the risk for drive failure. In addition, these integrated components are submerged in a cooling media, thereby eliminating the need for a fan - the most fail-prone component of a traditional VFD.  This integrated design also eliminates potential errors from sizing, set-up and wiring.
• With  4320 you know exactly what is going on without having to touch the mixer – or even leave the control room. Integrated monitoring functions include power consumption, energy meter, running time, drive temperature, phase loss alarm and overload.
• Flygt 4320 automatically senses when overload conditions are imminent and adjust output while providing notification to the operator. Motor protection is built-in and protect from mechanical damage due to overheating and over current.
• From the reduced wear of the mixer itself-thanks to generating mixer output with lower speed-to its advanced motor, Active Seal technology and durable hydraulics, Flygt 43200 offers low maintenance costs.

Reduce Mixer Inventory

Flygt 4320 have multiple duty points and can easily be deployed across different applications, reducing the need for inventory of back-up mixers and spares and also lowering capital investment for rebuild or mixer replacements.
