Installation and Maintenance
CTW Corporation offers variable frequency drive (VFD) installation and maintenance options to all of our customers. Our factory supported team of engineers have developed a comprehensive program utilizing this advanced technology. Learn how CTW’s variable frequency service can help save you money on your energy costs.
What is VFD?
VFD stands for variable frequency drive. The VFD has two main purposes: to control the output frequency and to convert incoming single phase power to a three phase power. Here’s a quick breakdown on how these two processes work.
Controlling the Incoming Electric Frequency
For well pumps to accelerate and decelerate during a cycle, they depend on incoming electric frequency; 60hz. VFD systems sequentially control the motor output frequency, increasing acceleration time and reducing water pressure surges. This process causes a gradual ramping and extends the life of the controlled equipment, like the motor and distribution piping.
Incoming Single Phase Power Conversion
Properly sized VFDs can operate three phase motors with the incoming single phase power. This method converts the single phase into a three phase, allowing the use of more plentiful, more efficient and less expensive three phase motors.
The Benefits of VFD Equipment
Installing a VFD system for your water well garners many benefits, such as:
High Level Protection
Having clean water throughout your home and business is important. VFDs offer a high level of ground fault, thermal and overload protection that shields the motor from damage.
CTW partners with Focus on Energy, which offers financial incentives to clients who install VFD systems for their wells. Please give us a call and we’ll walk through the process with you and handle the paperwork. Over the last seven VFD projects, our customers earned a combined total of $73,000 in incentives for their contributions to carbon footprint reduction.
Decreases Maintenance Costs
VFD’s are extremely efficient and will not put undue stress on your pump and pumping system. In the long run this will save on repair costs and system interruptions.
Reduces Your Energy Consumption
Compared to traditional well pump controls, VFD equipment allows the speed of the pump to vary. As a result, the pump is only consuming as much electricity as needed for demand of the home or facility. Starting a pump motor requires 9x the running amps, while a VFD operated pump will never exceed 1x the running amps – this is efficiency.
Significantly Reduces your Carbon Footprint
At CTW, we care about our environment. Our VFDs have helped to reduce the carbon footprint through non-renewable energy conservation. Thanks to our clients, we’ve prevented the burning of 480 tons of coal. As a result, we’ve reduced the time we have to drive to a service call, theoretically eliminating 150 cars from the road a year.
Let CTW Help You Save Money
For over 40 years, CTW Corporation has worked with municipal, commercial and residential property owners to provide well maintenance services. We have an entire team of experts, including in-house certified VFD installers that can help improve your water well’s function.
In addition to our VFD installation, we offer emergency services and will respond to your needs within the hour. Ready to save money on those energy bills? Call us today. One of our technicians will listen to your needs and help you schedule a well assessment with one of our VFD specialists.
