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 Controls processes automatically to ensure that the specified values (e.g. pH: acid or alkaline) are maintained even in the event of interfering influences. more in the glossary.
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.
