Description

Big Fogg offers Variable Frequency Drive Misting Pump operating at 230 volt. These High-Pressure VFD Misting pumps can reduce electricity use by HALF compared to conventional misting pump systems.

Our exciting new line of VFD Misting Pump Systems are most commonly used in all areas of misting that have several zones or noise sensitive areas. These pumps can slow down and speed up as zones are opened and closed which makes the pump produce 1000 PSI of pressure at any flow rate.

These pumps are great for: High Residential Misting, Restaurant Patio Misting, Greenhouse Misting, Poultry Misting, and Livestock Misting, Humidification, Dust Control, and Odor Control.

Variable Frequency Drive Misting Pumps (VDF)

VDF’s are the most efficient high-pressure mist ing pump in the market. They consume approximately 25% less electricity than non-VDF systems due to the inclusion of the VFD inverter and the way it utilizes electricity. This is one of the first of three electricity related efficiencies associated with a VFD mist pump but it is the primary reason VFD units are desired for many commercial and industrial applications.

Because of the inclusion of a pressure transducer in VFD Misting Pump, the system also provides the unique capability of only turning the motor at the required hertz based on the flow demand at any given time. This unique feature provides a variable operating speed for the motor. In most cases, the motor AND the pump are both spinning at an rpm level that is less than a standard Direct Drive or Pulley Drive unit. The result is not only a substantially quieter operating mist pump, but also a mist pump that requires less electricity to operate. This is the second of three electricity related efficiencies associated with a VFD misting pump.

As an example, if a 2 gpm system utilized a Direct Drive pump, both the pump and motor would turn at 1750 rpm. A Pulley Drive unit would require the motor to turn at 1750 rpm but the pump would only turn at about 920 rpm (using a bare pump that provides 3.8 gpm at 1750 rpm). A VFD unit would allow the motor AND the pump to both turn at 920 rpm (using a bare pump rated at 3.8 gpm at 1750 rpm). The result of this is the Direct Drive would be the loudest; the pulley drive would be quieter than the Direct Drive; the VFD would be significantly quieter than the Pulley Drive.

As system flow requirements increase, the VFD will progressively increase the speed of the motor until the pump is providing the required flow to achieve the required 1000 psi pressure. As this motor speed increases, it will increase the noise level and it is possible that if the motor and pump are required to spin at full hertz and rpm (60 and 1750 respectively) due to the maximum flow requirement for the system, the noise level for the VFD in that scenario could be equivalent to the noise level of a Direct Drive or Pulley Drive unit of comparable size. However, because the VFD unit affects the speed of the motor being used, it is always possible to resize the VFD unit so that it never spins above a desired rpm.

Other than the power consumption savings on commercial or industrial systems and not accounting for any noise level considerations, a VFD is most typically used when the system includes multiple zones but flow for the system at any given time is less than 50% (and may as low as 5%) of the pumps capacity. In these cases, the VFD has the ability to manipulate the power supply to the motor and thereby affect the motor rpm such that the pumps resulting flow output exactly matches the systems requirements at that point in time.

That means there is no bypass in the system (since there is no excess water being pressurized and bypassed, there is no heat build up in the water supply for the pump so damage to the internal components of the pump is eliminated) which means the system operates more efficiently because the pump is not over working itself by producing excess pressurized water. This is the third of three electricity related efficiencies associated with a VFD pump.
