Speed Variator for VASCO NASTEC Pumps

VA riable S CO , VASCO is a family of variable speed drives, manufactured by NASTEC , specially designed to control and protect pumping systems based on the speed variation of electric pumps.

Pump systems are often oversized for the application and use more energy than necessary. With energy savings of up to 70% at partial loads alone, the typical investment is recouped in less than 2 years, depending on energy costs and pump runtime. A motor at 80% of its maximum speed uses 48% less energy and reduces carbon emissions.

Available controls include constant pressure, system curve, constant flow or an external signal.

In addition to these functions, NASTEC - VASCO is capable of tasks that are normally only performed by more advanced computerized control systems, such as:

Stop the pump or pumps in the event of a water failure; enabling dry-running protection;
A second pressure value that allows switching between two different pressure settings, via an external switch;
Sensor failure;
Over temperature of the inverter and motor that protects the electric pump from under or over voltage.

Other features include:
Automatic initial tests;
Reversing the direction of motor rotation;
Inverter fault signal memory;
An operating hours counter.

Unparalleled user experience Thanks to the “ Nastec NOW ” application, it is now possible to communicate with the drives via Bluetooth with the possibility of:

Monitor multiple operating parameters simultaneously on your smartphone.
Get energy consumption statistics and alarm history.
Run operation and programming reports with the possibility of making notes with images and sending them by email or keeping them in the digital archive.
The inverter's settings and parameters can be saved in a file, with the possibility of copying them to other inverters and sharing them among several users.
Control the inverters remotely, using a Wi-Fi or GSM network through a smartphone placed close to the equipment that will function as a modem.

Improved usability via:

Monitoring and programming via your smartphone and the Nastec NOW application available for Android, IOS and Windows Mobile;
Remote control using a nearby smartphone as a modem;
Save and load schedules;
Possibility of sending reports by email;
Multi-language support. Various control modes: Constant pressure; Constant or proportional differential pressure; Constant temperature; Constant differential temperature; Constant flow rate; External frequency control (trimmer) or 1 or 2 preset frequencies.
