Automatic Energy Optimization
The standard feature AEO provides optimized motor magnetization at all speeds and loads. This increases energy efficiency by 5-15% for partial loads.
The VLT AQUA Drive provides a complete range of energy consumption information, which helps identify low-efficiency components in the system.
PM motor support
Support for any non salient permanent magnet motor up to 22 kW for better system efficiency.
Pipe Fill ModeEnables controlled (closed loop) filling of pipes. Prevents water hammering and bursting water pipes, or blowing off sprinkler heads.End of Pump Curve detects breaks and leakageThe feature detects breaks and leakage. End of curve triggers an alarm and shuts off the pump, or performs another user defined action. Dry Pump Protection lowers maintenance costs The VLT AQUA Drive constantly evaluates the condition of the pump based on internal frequency/power measurements. Deragging
Can be used as a proactive or reactive feature of the AQUA Drive for wastewater applications to prevent clogging of pumps. Deragging helps to avoid downtime and reduces maintenance cost.
Cascade controller solutionsThe built-in standard cascade controller controls up to three pumps with a fixed lead pump. The optional Extended and Advanced Cascade Controller makes it possible to extend the number of pumps and ensure smooth staging/de-staging, also in mixed pump and variable speed pump applications.Motor AlternationThis built-in logic controls alternation between two pumps in duty/stand-by applications. Motion of the stand-by pump prevents the pump from sticking. An internal timer assures equal usage of the pumps.Flow compensationThe flow compensation feature reduces the pressure set point according to the flow, which saves energy. Initial/Final RampThe initial ramp provides fast acceleration of pumps to minimum speed, from where the normal ramp takes over. This prevents damage on thrust and bearings.
Check Valve Ramp
The Check Valve Ramp of the VLT AQUA Drive prevents water hammering as check valves close smoothly when the pump stops.
The user-friendly Quick Menu, and its submenus of the VLT AQUA Drive, saves time during drive configuration. The submenu "Water and Pumps" provides direct access to application specific features.
A wide selection of accessories is available for the VLT AQUA Drive to suit your needs. For further details see the Operation Instructions.
