Non Enclosure VFD - 1HP

GK3300 Series economic low cost 1HP Non-Enclosure variable frequency drive (VFD) with compact design, it's the best choice for integrate system solutions. As there is no enclosure on GK 3300 series VFD, the price is extremely cheap. You can install multi VFDs into a big cabinet, which is very useful in textile machines and other highly-integrated applications. Since this non enclosure VFD being manufactured by Gozuk, it has been widely applied in weaving machines in textile industry in local China and global countries.

Tips: VFD vs. Valve on pumps
Running a primary pump at full speed and then bringing on a second pump full speed on a demand just past the first pump's duty point means we now have two pumps running slightly over 50% each - not real efficient. The VFD setpoint controller, i.e. pressure etc, will throttle both pumps to maintain the required system a parameters.

Another problem with multiple parallel pumps using Pressure Reducing Valves instead of VFDs - if the Pressure Reducing Valve settings are not all balanced (the same), the pump with the lowest setting may "hog the load" if the settings are too far off. The pump with the higher setting sees this as over pressure and wants to throttle closed. This is worse on flat curve pumps for constant pressure. On larger systems you can add load sharing controls based on amps - like generators do.
