  • Why VFD?  Top 20 advantages to powering a pump or fan motor with a Variable Frequency Drive... 
     
    1. Regulates pressure at varying flow 
    2. Converts single phase to three phase power 
    3. Eliminates need for power line installation to bring in 3-phase power 
    4. Provides precise speed control of an AC motor 
    5. Generates full torque from the motor at very low speed 
    6. Allows simple setpoint control throughout the speed range 
    7. Protects the motor and wiring from overload currents 
    8. Provides built in Power Factor correction 
    9. Highly efficient – 97% minimum 
    10.  Limits in-rush current at start-up (Power Companies will love this one!)  
    11.  Adjustable soft-starting (acceleration time) 
    12.  Adjustable soft stop (deceleration time) 
    13.  Protects mechanical equipment/piping by eliminating water hammer 
    14.  Allows a simple connection to a communications network 
    15.  Provides substantial energy savings on pump and fan applications 
    16.  Automatic restart after instantaneous power loss or failure 
    17.  Power failure-time deceleration-to-stop function 
    18.  No power used during “off” time 
    19.  Electronic thermal overload relay 
    20.  Energy saving operation and energy saving monitor 

Agriculture

In January of 2008, Watertronics became part of Lindsay Corporation, a Nebraska-based global manufacturer of agricultural irrigation products.  Being a market leader in pump and control innovation, Watertronics was an excellent fit for Lindsay — matching water supply with water distribution… pumps with pivots.   
 
Watertronics products include not only pump stations, but advanced controls technology for high efficiency pumping that produces significant energy savings and labor savings.  Today the Ag market is benefiting from advancing irrigation efficiencies, available through Lindsay’s worldwide Dealer network.   
 
In recent years, the Ag industry has started to utilize Variable Frequency Drives, or VFD, to regulate water pressure, efficiently matching pump output to water demand.  Combined with Programmable Logic Controllers, the VFD is bringing real change to the Ag market.   
And the result?  Lower overall cost of operation. 
 
As the world strives to reduce energy consumption, companies like Watertronics are improving efficiencies and effectively reducing power consumption.  Solutions include converting from single-phase to three-phase power, minimizing the need for new power lines, running grain bin dryer fans on VFDs with variable speed controls to automatically adjust when full speed is not needed—these are but a few of the products Watertronics is bringing to the market today. 
 
Irrigation systems frequently include multiple irrigation heads run off singular or multiple pumps.  Controlling these pumps with VFDs allows the system to run only as many irrigators as necessary at a given time – a capability that for years was not available.  Wasted energy and over-irrigation has now been replaced with intelligent irrigation and precision control.
