Designed for industrial steam boiler installations up to 100 bar, the AQ300 accurately monitors the boiler and feed water conditions. It injects exactly the required amount of chemicals and provides auto surface blow down control. It keeps the entire plant within the desired chemical limits, 24 hours a day, regardless of load.

The units can be fitted with a mixture of pumps of pumps and programmed for different pressure Boilers and water treatment chemicals.

The system includes pH, conductivity, dissolved oxygen, temperature probes, data commumications unit with software, feed flow meters, auto blow down valves, test kit and dosing pumps complete with suction assemblies and low level alarms.

The software provides for continuous display of all important readings and pre-formatted ?Management Reports? which outputs a summary of average readings for any period requested. The unit can be linked to other AQUANET systems and all readings are displayed on one monitor. The system is pre-configured for each installation and a choice of coolers, pumps, flow meters and blow down valves are available depending on requirements. Installation can be carried out by the owners staff, sub-contractor or AQUANET personnel.
