The UNIcon control module controls fans mounted on coolers, for example, dependent on pressure or temperature. For this, a 0-10 V signal is output.
To additionally increase the cooling performance (in peak load times), the control module can switch on up to three moistening stages by relays. Usually these relays activate servo motors which open valves and ensure moistening of the air sucked in by the cooler. The air can be cooled additionally by evaporation and ensures and increase in the cooler performance.
The UNIcon also controls the pump for the water supply line, closes or opens valves for the frost protection function (close main supply line, open valves for draining).
