Nastec - Variable Frequency Drive
VASCO - Pump Controllers
VASCO is a purpose-built family of variable frequency drives, designed to control and protect pumping systems based on changing pump speed. From water supply for domestic, irrigation, commercial and industrial applications, to heating and air conditioning, from filtering to pressure washing, the VASCO range perfectly fits any new or existing application ensuring:
VASCO units are extremely compact and, connected to our PEARL pumps, will manage the operation of the pump to maintain a constant desidered physical dimension (such as pressure, flow, temperature or other).
The pumping system runs only at the speed necessary to meet user’s requirements, ensuring energy savings and extending the life of the system.
Vasco also provides motor protection and monitoring , such as:
Protection against overload and dry running
Integrated soft start and soft stop functions, extending the life of the system and reducing peak absorption
Indication of input current and supply voltage
Recording running hours and loggins errors and alarms reported by the system
Vasco can control a second or third pump at constant speed DOL (DOL: Direct On Line)
Connect to other VASCOs to get combined operation
Body is constructed entirely of aluminum, making VASCO , with its compact dimensions, extremely solid, lightweight and easily cooled, adding to the unit’s versatility.
The degree of protection, IP55 makes it possible to install VASCO virtually anywhere, including humid and dusty enviroments; the liquid cristal illuminated display ensures VASCO is easy to operate and a buzzer provides an immediate indication of alarm.
VASCO can be installed directly on the cooling fan cover of the motor or directly to the wall with a supplied installation kit:
VASCO is cooled by the motor cooling fan.
Motor kits consists of 4 special clamps to fix the VASCO to the motor fan cover.
VASCO is cooled by an external cooling fan attached to the inverter radiator.
A special metal bracket is supplied for VASCO to be mounted to the wall.
