Main functions and features
The water business market including water purification plants and wastewater plants has continued to grow in recent years. Using a large volume of water, cost reduction is required and it largely depends on how efficiently water can be managed. It is of course achieved by reducing the amount of water to be used, however, the reduction in power consumption in water transfer and supply also allows significant cost reduction.
And the key to that is the dedicated inverter which controls pumps and motors.
The FRENIC-AQUA series, a Fuji’s new product, helps energy-saving of pumps, eliminating ineffectual operations by adjusting the amount of water properly to produce a significant effect both on electricity conservation and on cost reduction.
Wide variation in model capacity
Model can be selected from two model types.
■Standard type (EMC filter built-in type)
0.75 to 710kW (Protective structure IP21 or IP55 can be selected between 0.75 and 90kW.)
■DCR built-in + EMC filter built-in type
0.75 to 90kW (Protective structure IP21 or IP55 can be selected between 0.75 and 90kW.)
|Inverter capacity||EMC filter||DC reactor||Protective structure|
|0.75kW to 90kW||Built-in||Built-in||IP21/IP55|
|110kW to 710kW||Built-in||External||IP00|
* The models with inverter capacity 45kW to 710kW are coming soon.
