Managed by inverter panel (VAR)

DESCRIPTION

Pressurization units with 2, 3 or more electro pumps with automatic functioning managed by panel with 1 inverter and 2 (or 3, depending on the number of pumps ) direct starts (up to 11 kW) or delta star, complete with rotation of the inverter in all the pumps, by-pass for the functioning without inverter and alternation of th pumps.

IDROPRESS VAR - OPERATING LOGIC

Pressurization units VAR series with automatic panel with 1 inverter that controls and regulates, by means of pressure transducer, the first pump on the basis on demanded water capacity, keeping the constant pressure in the system. When the water demand changes, the second pump and the possible other ones, are activated automatically back to back (with direct or delta star starting). In order to optimize the functioning of all pumps, the panel calculates a starting in alternation. In this way there is the same work load on all pumps.
IDROPRESS VAR units calculate assistance starting by means of pressostats (one for each pump), in order to assure functioning continuity of the system, and also in case of break of inverter master.
