Full flow sequencing of multi-pump stations assures efficient operating combination of pumps. Automatic alternation of equal pumps reducing wear and extending motor and pump life. VFD stations require no routine maintenance, provide maximum energy savings, and minimize operator training. Here are some features to compare. High frequency carrier control drive system for quiet operation.
Drive is supported by manufacturer service and parts centers world-wide.
Special cabinet and drive designs enable cooling by heat exchanger, saving energy, reducing noise, and prolonging cooling unit life. Units relying on air conditioners waste energy, are noisy, subject to more maintenance and moisture buildup in the control panel. Automatic pressurization program slowly pressurizes the system at startup, or after long shut downs. Automatic break or other failure monitoring during pressurization. Air eliminator on header discharge for more effective elimination of system air.
