The new and intelligent frequency converter (FU), which the water technology company Xylem is now presenting, is extremely reliable and suitable for numerous applications in residential buildings. For example, the Lowara ResiBoost increases pump performance, reduces wear and possible damage, and thus increases the life of the pump. By maintaining a constant system pressure, it reduces energy consumption while maintaining high performance.
The Lowara ResiBoost is a "plug-and-play" solution and easy to set and operate. The frequency converter is available for water-cooled direct mounting on the pump or as a wall mounting version and can be installed flexibly. The user only needs to connect the frequency converter to the water and power line, set the desired pressure, and the unit is ready for operation. The soft start and stop function prevents pressure drops that can damage pipes, connections and valves. The life and reliability of the pumps are increased because they are not constantly operated at the highest speed. This also reduces the energy costs and also means less mechanical stress and a lower noise level of the pump.
After power failure, the settings of the Lowara ResiBoost are automatically restored. It is equipped with an LCD display, in which error messages and operating data such as operating hours and number of pump starts are displayed in an easily understandable form.
From underwater pumps to pressure elevators, the ResiBoost frequency converter is an ideal solution with the best price / performance ratio. It can be used to control the highly efficient Lowara pumps such as the horizontal multi-stage pumps, 4 "and 5" well pumps as well as single-stage centrifugal pumps.
