VARIABLE FREQUENCY DRIVES and SOFT STARTERS

For advanced motor control, NOARK provides Ex9VF7 series VFDs and Ex9QR5 series soft starters, which are suitable for pumps and compressors.

Noark’s Variable Frequency Drives are designed to control the speed and torque of an electric motor by varying the frequency and voltage of its power supply, improving energy efficiency and providing precise control in HVAC applications. The series Ex9VF7 Variable frequency drives’ operational voltage range options are Single phase @110V & 230V; and Three phase @230V, 480V & 600V.

Advanced Control & Energy Optimization

Ex9VF7 Series VFDs

  • Motor speed control for pumps, compressors, and large fans
  • Built-in HVAC functions (PID, soft start, energy control)

NOARK’s Soft Starters are designed to facilitate soft-start and soft-stop of three phase electric motors. It provides the overload protection required for motor branch circuits, while also saving energy, reducing peak-demand charges, and limiting mechanical wear and damage to connected machinery.

Ex9QR5 Series Soft Starters

  • Reduce inrush current
  • Minimize mechanical wear on compressors and pump systems

Power Distribution:

Low Voltage Switchgear, Panelboards, and Enclosed Breakers for distributing power within HVAC units.

Pilot Devices:

Pushbuttons, Selector Switches, and Indicator Lights for user interface and signaling
