Nastec VASCO V409 Inverter (4kW)

Nastec VASCO V409 Inverter (4kW): Intelligent Pump Control for Diverse Applications

VASCO is a purpose-built family of variable frequency drives (VFDs) designed to optimise the performance and protect the integrity of pumping systems by precisely controlling pump speed. This versatile range is suitable for a wide array of applications, including:

• Domestic water supply and irrigation
• Commercial and industrial applications
• Heating, ventilation, and air conditioning (HVAC)
• Filtration and pressure washing

VASCO's compact units connect to virtually any pump, intelligently managing its operation to maintain a constant desired physical dimension (such as pressure, flow, or temperature). By operating the pump only at the speed required to meet demand, VASCO maximises energy efficiency and extends the life of the entire system.

Comprehensive Motor Protection and Monitoring: Overload and dry-running protection, input current and supply voltage indication, integrated soft start/stop (reducing peak absorption and further extending system life), running hour recording, and error/alarm logging.

Multi-Pump Control: Control of a second and thrid pump at constant speed DOL (Direct On Line), and connectivity for combined operation with other devices.

Robust and Versatile Design: The compact, all-aluminum body provides exceptional durability, lightweight handling, and efficient cooling. IP55 protection allows installation in diverse environments, including humid and dusty locations. An illuminated LCD and buzzer provide clear operational status and immediate alarm notification. 

VASCO variable speed drives offer a cost-effective, fully featured, motor-mountable solution (wall mounting kit available, sold separately) suitable for retrofitting to various pump types. By enabling pumps to operate below maximum speed when full power is not required, VASCO delivers significant energy savings and reduces pump wear. Integrated features include a pressure transducer, dry-run protection, soft start, and a duty pump changeover timer.
