Desalination plants Desalination plants are used to provide clean drinking water from the sea. The process uses high pressure pumps, which must be carefully controlled. With its built-in PID controller, the VLT֮ AQUA Drive ensures reliable and precise pressure control, maximising process control and effi ciency. Groundwater pumps Submersible deep well pumps need fast start capability, precise control and protection against running dry. The built-in dry run detection and the initial ramp-up make the VLT AQUA Drive handle such applications to perfection. Wastewater plants Fluctuations in fl ow...

Irrigation systems In irrigation today great concerns are put on effi ciency and energy savings in the water management. Precise pressure control is required. The built-in pump control makes VLT AQUA Drive a perfect match for irrigation in rural areas. It even off ers a special pipe fi ll function that prevents water hammering and reduces leakage when empty pipes are fi lled. Distribution Pressure booster pumps with precise pressure control lead to signifi cant reductions in water leakage and energy consumption. Costly and unsightly water towers can be elimi na ted. Built-in features make transducer...

Auto tuning of the PI controllers With auto tuning of the PI con - trol lers, the drive monitors how the system reacts on corrections made by the drive and learns from it, so that precise and stable operation is achie ved quickly. Pipe Fill Mode Enables controlled (closed loop) fi lling of pipes.Prevents water hammering, bursting water pipes or blowing off sprinkler heads.The new pipe fill mode is usable in both vertical and horizontal pipe systems. Gain factors for PI are conti nuously changed to compensate for changing characteristics of the loads. This applies to each PI controller in the...

Sleep Mode Sleep Mode keeps pump wear and power consumption to an absolute minimum. In low fl ow situations, the pump will boost the system pressure and then stop. Monitoring the pressure, the VLT AQUA Drive will restart when the pressure falls below the required level. Dry Pump Protection lowers maintenance costs The VLTή AQUA Drive constantly evaluates the condition of the pump, based on internal frequency/power measurements. In case of a too low power consump-tion indicating a no or low fl ow situation ֖ the VLT AQUA Drive will stop. Motor Alternation This built-in logic controls alternation...

Athens Wastewater Treatment Plant, Greece VLT drives up to 315 kW handle wastewater from a population of 5 million in Athens. VLTή operation saves approx. 25% energy. The Psyttalia Wastewater Treatment Plant treats daily 750.000 m > 3 of sewage and has a nominal daily capacity of 1.000.000 m > 3 . >

Monterrey City, Mexico Agua y Drenaje de Monterrey in Mexico is install- ing Danfoss VLT drives in wastewater treatment plants, boost pump stations and water wells for both residential and commercial areas in Monter- rey Ζ the largest industrial city in Mexico with 3.5 million people. Benefi ts from VLT operation of the pumps are energy savings of about 30% and also reduction of water leakage.
