A Variable Frequency Drive (VFD) system is one of the most cost effective units to run and to maintain and they are extremely easy to use. The VFD display makes is simple to trouble shoot. The VFD display shows various input signals which can be used to visually display and indicate system faults. The VFD system offers substantial operational and maintenance savings. A variable frequency drive extends the life of the motor, pump, and pump components. A VFD significantly reduces maintenance or service related issues. The system will only utilize the power (speed of motor and pump) to match the output demands. For example: A 20 gpm system, set up for 4 users at 5 gpm each. If there is only one user on the system outputting 5 gpm, the motor/pump will only turn at 1/4” speed to meet that demand. The VFD system shows a savings in energy costs to run the system, it only uses what it needs. On system start-ups, a VFD controlled system slowly ramps up speed to the minimal required rpm to meet the initial demand. This eliminates the huge inductive amperage load a system with standard controls requires when starting. A VFD system does not require the use of motor contactors, overloads, and fusing.
VFD benefits
- Energy savings
- Smoother quieter operation, eliminate water hammer
- Extend pump life
- Extend system component life
- Extend motor life
- Reduce maintenance
Functional Design
- Real-time system monitoring and control (wash station duty cycle/activity, low inlet water supply and system pressure loss shutdown, and high water temperature shutdown)
- Compact and versatile design allows for installation in virtually any location/environment
- Systems designed/built to application requirements – provides for increased productivity
- VFD increases or decreases pump/motor speed to meet the demands of single and or multiple users
