Product description

New features and functions – one big step for DULCOMARIN, one gigantic step for your pool system.

The measuring and control system DULCOMARIN 3 is a reliable system for the treatment of swimming pool water.

The intuitive menu navigation is also supported by videos and shows step-by-step calibration When a metering pump has been installed, the capacity in litres per hour has to be determined under ... more in the glossary of the sensors.

It is operated using the system’s touch display. You can also operate the DULCOMARIN 3 remotely online. This connects you to your DULCOMARIN 3 using your smartphone or any other Internet-compatible end device (VNC app needed). You can therefore also control other features, lighting, circulating pumps and filter backwash. The system can be extended at any time to meet future requirements.

The circulation capacity of the pumps adapts to the water quality in Eco! operating mode. Chemicals are metered precisely depending on demand based on the measured values, reducing ongoing energy costs and saving chemicals.

The DULCOMARIN 3 Global Unit is the central element of the measuring and control system. All information relating to the individual pools and associated control circuits is collated here. Use the DULCOMARIN 3 Compact version for one filtration circuit, and the Global Unit, which can display up to 16 Local Units, for multi-pool systems with up to 16 filtration circuits. Networking is provided by the LAN-based cNet.

DULCOMARIN 3 has the following communication options as standard:

Modbus RTU
OPC OPC stands for Openness, Productivity, Collaboration (formerly OLE for Process Control) ... more in the glossary UA
BACnet IP
Web interface
VNC server

A gateway to Profinet is available as an option.
