ProMinent SlimFLEX - Model 5a - Controller
From Measuring, Control and Sensor Technology - Controllers
The cooling tower regulator SlimFLEX 5a continuously measures and controls conductivity and controls biocide metering, keeps pipework and heat exchangers clean and prevents legionella.
Overview
Controller SlimFLEX 5a, the entry-level class for cooling water treatment, VDI 2047 Sheet 2 and BIMSchV 42-compliant, the innovative and flexible controller.
The SlimFLEX5a records all the important measuring parameters for cooling water treatment and controls functions necessary for smooth operation:
- Time-dependent biocide metering (boost metering). Checks can be undertaken by measuring the ORP voltage in the cooling water.
- Measurement of electrolytic conductivity – controls bleeding.
- pH measurement with integrated PID controller.
Your Benefits
- A web interface for device configuration and remote maintenance is standard, Wi-Fi is available as an option
- Forced bleeding: performs bleeding before biocide metering
- Bleed lock: blocks bleeding after biocide metering has taken place
- Operating status displayed by 6 status LEDs
- Connection to the DULCONNEX IIoT solution, developed by ProMinent.
Field of Application
- Control of bleeding in smaller evaporation cooling systems
- Volume-proportional control or regulation of the metering of corrosion inhibitors, de-foamers and dispersants
- pH measurement and optional pH control
- Time-dependent metering of up to 2 biocides
Technical Data
- 6 digital inputs for contact water meter, flow detector and control signals
- 6 status LEDs display the operating status
- 5 flexible relay outputs: for setpoint-dependent flow volume-proportional or time-based control of actuators
- Measured variables: Conductivity, pH, ORP
