AS3020

This is a cooling tower controller

AS3020 cooling tower controller

Description

The unit type AS3020 is universal applicable for automatic monitoring and control of cooling tower plants. The controller is equipped with an conductivity meter without temperature meter. There are three possible stages : "Service", "Flush" and "Flush wait". This unit can monitor conductivity and several inputs e.g. level switches, low pressure switch, exceeded pressure and stop. Adaptable to user specific requirements by built-in programmable options. The programmed configuration will be stored into non volatile memory and therefore not be affected by power loss.
