1-2-3 KVC A.D. are variable speed pressurisation units with 1, 2 or 3 vertical axis multistage centrifugal pumps particularly suited for domestic use, and small civil or industrial systems.
Thanks to the use of the Active Driver Plus inverter, they offer performance features capable of automatically adapting to the different needs of the systems to meet the constant pressure requirements of modern system engineering solutions. The constant pressure adjustment is a requirement in the most varied sectors: Water pipelines, Irrigation, Industry, Hotel, Residential building, Spas.
Their main features are reliability, simple operation, and minimum maintenance requirements.
