UNIPUMP VARUNA - inverter for single phase electric pumps
UNIPUMP VARUNA inverter for single phase electric pumps is electronic device, based on the use of frequency converter, controls electric pump motor on/off. Varuna modulates input current frequency (Hz) of the pump motor changing its rotation speed proportionally to water flow that allows maintaining water supply system pressure at one and the same level. Electric pump motor power is proportional to water flow that allows substantial energy saving with constantly changing water consumption within 24 hours (for instance, in apartment blocks).
