Invertek Drives frequency inverter Optidrive Eco pump series

Energy Efficient Pumping.

When a pump or pump set is selected, it must be suitable for operation during periods of maximum flow demand. In many applications, this maximum flow level may be rarely required, and as such the pump may operate for long periods at less than maximum flow capacity. By varying the speed of the pump to match the actual flow demand, significant energy savings are possible. Optidrive Eco Pump has been designed to maximise the energy savings potential in pumping applications, whilst also providing significant additional benefits in reduced installation costs, maintenance costs and downtime. Throughout all this, Invertek’s “Ease of Use” philosophy ensures that advanced features are simple to commission, without requiring extensive, in depth knowledge of a huge number of parameters. Optidrive Eco Pump has a simple menu structure, and provides just the right amount of parameters to allow flexibility without over complication. Overall, this provides the perfect balance of Easy to Install, Easy to operate, Advanced Pump Control.
Save Energy.
Eco vector operation, based on Invertek’s advanced motor control provides the most energy efficient operation of the pump, continually optimising the output to match the required flow with minimum energy consumption. Advanced sleep & wake functions provide maximum energy savings by switching off the pump when not required.
Save Money.
Optiflow technology allows simple operation of multiple pump sets without the need for a PLC Pump blockage detection and cleaning dramatically reduces pump maintenance requirements Built in PLC function allows bespoke customised applications to be programmed directly in the drive.
Save Time.
Simple parameter set allows fast commissioning of pump control systems Pump operating curve detection automatically detects and monitors normal pump behaviour and is able to react when pumping conditions change Customisable OLED display provides excellent visibility of drive status and operation in all conditions.

Maximum Pumping Efficiency with Invertek Drives frequency inverter Optidrive Eco series.

Unique Eco Vector Sensorless Control.
Optidrive Eco Pump uses advanced motor control technology, designed to provide the most energy efficient motor control possible. Operation with standard IM Motors, Permanent Magnet or Synchronous Reluctance motors is possible, all without requiring any feedback device or optional modules – simply change parameters to suit the connected motor, autotune and operate! Eco Vector continuously adjusts in real time to provide the most efficient operating conditions for the load, typically reducing energy consumption by 2 – 3% compared to standard AC drives – providing similar long term costs savings to selecting a higher efficiency motor.

Energy Optimised Design.
Optidrive Eco Pump up to frame size 5 are designed with film capacitors, replacing the traditional electrolytic capacitors used in the DC link. Film capacitors have lower losses, and also remove the need for AC, DC or swinging chokes, improving overall drive efficiency. Efficiency is improved by up to 4% compared to standard AC drives, whilst also reducing supply current total harmonic distortion (iTHD), improving the Real Power Factor and reducing total input current, leading to cost savings on installation through reduced cable and fuse ratings and smaller supply transformer rating. Improved Efficiency, Reduced Lifetime Costs: e.g. for a 37kW load, operating 10 hours per day, 5 days per week, 50 weeks per year, improving the efficiency by just 1% will provide an energy saving > 900kWh per year.

Pump Prime with Burst Pipe Detection.

Pump prime mode allows starting of the pump in a safely controlled manner, to ensure consistent filling and pressurisation of pipe work and systems. Low pressure warnings are ignored during priming to allow the system to prime correctly, whilst a failsafe timeout prevents the pump from continuing to run in the event of a failure to prime. This helps to prevent the effects of water hammering (such as bursting water pipes) or damage to fountain / sprinkler heads. The time limit, set for pump prime mode to complete, means that the pressure in the system must reach the minimum level within the set time. Failure of the system to pressurise would indicate a leak or burst pipe within the pump system and result in the Optidrive Eco Pump shutting down the pump. During normal operation the system pressure is still continuously monitored against the minimum level so that a burst pipe during normal operation will likewise result in the drive tripping ‘low pressure’ and shutting the pump down.

Avoid Pump Downtime with Invertek Drives vfd Optidrive Eco series.

Blockage Detect/Clear.
Optidrive Eco Pump can detect pump blockages and trigger a programmed cleaning cycle to automatically clear them, preventing downtime.

Dry Run Protection.
Optidrive Eco Pump can evaluate a pump’s speed/power and shut it off or warn when the pump starts to run dry, protecting it from heat/friction damage.
Motor Preheat Function.
Optidrive Eco Pump features a motor preheat function to help ensure moisture is not permitted to collect on the motor in periods of inactivity and prior to motor start up. In addition, the motor preheat function can be used to keep condensation from developing on the motor as the motor cools down immediately following a stop. The feature is fully configurable, meaning the pump can be always available the instant it is required.
Pump Stir Cycle.
Triggered by a settable period of inactivity, a configurable cleaning cycle can be run to clear sediment, ensuring the pump is ready to run when needed.

- All drives operate at variable speed for maximum energy efficiency. 
- Operating time (Hours Run) is automatically balanced and duty pumps rotated 
- Automatic system reconfiguration in the event of a pump fault (including the master pump). 
- Continued system operation when drives are individually powered off (including the master drive). 
- Communication and +24V control voltage shared between drives via a standard RJ45 patch lead. 
- Independent maintenance indicators for each pump. 
- Any pump can be switched to Hand operation a the touch of a button, and will automatically rejoin the network when switched back to Auto. 
- For waste water applications each pump can be set for blockage/ragging detection and activate an automatic de-ragging/pump cleaning cycle. 
- Optional mains isolator with lock-off for safe pump maintenance. 
- Optiflow function configured through simple parameter set-up and intelligent drive self configuration.

Invertek Drives frequency inverter Optidrive Eco series Reduced Harmonic Current Distortion.

Optidrive Eco Pump uses innovative design to improve overall efficiency whilst minimising the harmonic distortion levels. All drives designed for 3 phase power supply operation1 up to frame size 5 utilise film capacitor in the DC link, providing exceptionally low harmonic current distortion without compromising efficiency. Frame size 6 and above include DC chokes and traditional electrolytic capacitors. Optidrive Eco Pump product range complies with the requirements of EN61000-3-12.
Optidrive Eco Pump delivers:
- Improved Efficiency, Reduced Lifetime Costs: e.g. for a 37kW load, operating 10 hours per day, 5 days per week, 50 weeks per year, improving the efficiency by just 1% will provide an energy saving > 900kWh per year 
- Improved True Power Factor – No additional charges etc. 
- Lower Mains Supply Current.

It can be clearly seen that the reduced DC link capacitance significantly reduces the total harmonic distortion at full load, and has a much greater benefit at part load compared to a conventional DC choke or swinging choke. This results in reduced overall input current and reduced transformer heating effect. Optidrive Eco offers improved power factor over conventional VFDs under all loads.
