VFDs have been around the irrigation market for a couple of decades now. Some regions long ago embraced the use of VFDs, and others are just now coming to realize their value. A VFD allows a pump to speed up and slow down as required to meet the demands of the irrigation system. If less flow or pressure is required, the VFD can slow the pump down and thereby reduce the amount of electricity the pump is using. This means a lower electric bill and less impact on the environment.
Installing VFDs can save a grower as much as 25 percent on pump operating costs. Evaluating the payback
In the corner machine example on pg. 25, a VFD could save the grower as much as 25 percent of the cost to operate that pump throughout the growing season. The payback on a VFD investment can be quick, often in a matter of a few years. In many parts of the country, utility companies offer rebates and cost-sharing programs for growers to install VFDs. If there is a program like this available in your area, your payback can happen even faster.
VFDs are a mature technology used in a wide variety of industries. Any irrigation situation that causes a change in pressure of flow can likely benefit from the use of a VFD. It’s a proven technology with a quick return on investment that can reduce your operating costs and boost your bottom line.
