The Ezetrol® plus controller has been designed for all types of swimming pools, spas and water features, both indoor and outdoor, that are dosed with chlorine.
It provides flexible measurement input options, offering parameters of free chlorine, pH and temperature as standard. The Ezetrol® plus can control chlorine and pH with metering pumps or with an electric positioner.
The Ezetrol® plus maintains the chlorine dose at the recommended standard values. Offering a free chlorine range of 0-10.00mg/l, from a robust amperometric potentiostatic free chlorine sensor, it can work with all types of pools, even with the low chlorine levels that are found with UV disinfection systems.
The Ezetrol® plus offers configurable 0-20mA outputs for BMS or chart recorders, as well as an on-board print manager and RS 485 connections for the optional ChemWeb server.
It is supplied pre-mounted on uPVC board for easy installation and routine servicing. It is also available with second sample cell and free chlorine sensor, for use with single water volume which passes through a common filtration system and is zoned for a distribution to a specific pool that requires monitoring and separate control.
