Coelbo Speedmatic Set 21110 MM Inverter.
Twin Pump Inverter
Inverter for two single phase pumps with alternated operation sequence. Patented system
Coelbo SPEEDMATIC SET ALT 21110 MM is a compact automatic control device designed for the automation of pressure groups with 2 pumps, with an electronic system managed by a software responding to the rigorous requirements of efficiency and safety.
It includes a frequency inverter for the main pump control regulating the speed in order to keep
constant the pressure independently of the flow given, the auxiliary pump is managed by mean of power relay.
There is alternated operating sequence, this means that the pump managed by the inverter is changed in each operating cycle and it is always the first to start
