Fan Inverter
Frequency control for Nederman fans in process ventilation systems.
Frequency control to maintain
constant system pressure
Nederman Fan Inverter is a frequency controller that is
preprogrammed with an extraction fan application for Nederman
fans. It is equipped with a pressure sensor and a PID controller
that can maintain a constant negative pressure in an extraction
system.
As a result, Nederman Fan Inverter can maintain an almost
constant airflow in extraction devices. The fan capacity is
regulated to the actual demand of the airflow, depending on the
number of extraction devices in use at the same time.
Nederman Fan Inverter comes with a clear multi- language
display to easily view and change settings.
Save Energy with Nederman Fan Inverter
The benefit of using Nederman Fan Inverter is that it reduces
running costs, heat loss to the atmosphere and noise levels. It
conserves energy and improves performance by regulating the
system’s power usage as the demand from extraction devices
increases or decreases.
• Preprogrammed for quick and easy commissioning
• Clear multi- language display for information and settings
• Fan timer included for automatic fan start/stop
• Built-in motor overload protection
• Energy counter
• Pressure supervision
