VFD - Variable frequency drive

Many water and wastewater companies use a professional installation service, such as that provided by authorized channel partners, to assist with the replacement. The authorized partners can undertake a pre-installation survey and advise about any modifications required for a successful installation, for instance if the ventilation needs improving or if the existing cabling is inadequate. They can also look at existing applications and advise about potential energy savings.
Upgrade
The next choice to be considered is whether the VFD is actually giving you what you want. During 20 years, technology moves on and today`s VFDs offer a whole raft of new functions that were only dreamed about in the early years. In many cases this does not mean you have to throw away your existing VFD. Depending on its age, you could decide to upgrade the technology to add functionality, either by downloading the latest software or applying a hardware update.
There are many reasons why this may be a good course of action. It could be that faster production levels are needed; or more process intelligence is required including exact energy saving levels measured in kWh, CO2 emissions or in monetary terms. In fact an upgrade can have a major impact on the actual process by bringing new levels of efficiency and end-product quality.
So an existing VFD can often be upgraded to the latest software or hardware to improve the performance of the application. Drive upgrades are designed for improving the performance and extending both the functionality and the lifetime of the VFD to provide end-users with the best possible return on their investments.
