A Human-Machine Interface (HMI) is the tool that allows the operator of a lift station to see data output and change parameters on the control panel. Typically an HMI is mounted on the control panel and consists of a 6”-10” screen with push buttons for the user. They range from black-and-white displays with limited push button controls to color displays with many layers of touch screen menus. HMI can also be referred to as OIT …

An automatic transfer switch is designed for switching of electrical loads between primary power and a standby generator. The switch monitors both power sources for stability. If the utility power becomes unstable, the transfer switch signals the generator to startup and then transfers power until the utility power source returns to normal. Romtec Utilities uses ATS when a permanent generator is included in the design of the lift station. The ATS is sized for the …

Soft starters and VFDs are each used to reduce the in-rush current on the electrical utility during start-up of the pump station and/or electrical generator. They are necessary when the utility has restrictions on the horsepower of the machine being started or if there is a soft utility line that cannot handle the in-rush. Soft starters accomplish this function with basic controls and are much less expensive than VFDs. While more complex and more expensive, …

Yes, Romtec can provide a generator for your pump station.
