EWS ES 2050 Duplex Controller Wall Mount 230/24V for Control Valve

Product Description

Water softener/filter controllers designed for the monitoring and control of simplex and duplex water softener installations.

Description

The ES2050(wall mounted) and ES2051(panel mounted) water softener/filter controllers are designed for the monitoring and control of simplex(single exchange column) and duplex(twin exchange columns) water softener installations. Whilst a simplex installation can not provide softened water to service when the exchange column is in regeneration, a duplex installation is capable of providing treated water from one column whilst the other is being regenerated. Duplex plants can be operated either in duty/standby mode(one unit in service, the other either in regeneration or waiting to be called into service), or in parallel mode(both units in service except when one is regenerating). The regeneration of an exchange column is effected either by one central control valve or by means of a pilot system controlling individual valves. Five volt free relay contacts are available for control of valves, pumps, lamps, etc. or can be used for remote monitoring.
