Multi Channel Measuring and Control System DULCOMARIN® II Pool Controller

The DULCOMARIN®II control system is the first bus system in swimming pool technology used to network equipment. The system is designed for public swimming pools and also for sophisticated private pools, and conforms to DIN 19643. The flexible system can be designed to meet requirements either as a compact or decentralised modular system and is designed to meet all future requirements

The DULCOMARIN®II can be configured in two ways:

DULCOMARIN®II compact: For controlling a single swimming pool
DULCOMARIN®II DULCO® -Net: For controlling up to 16 filtration cycles.

ProMinent made the idea a reality, achieving the task of measuring and controlling from one up to 16 filtration cycles using a single device. Even from two cycles considerable cost advantages are gained in comparison with traditional measuring and control systems, because only one single central unit is needed. Each filtration cycle has an in situ calibration option and can measure and control the following parameters:

pH value
free chlorine
total chlorine (only measured)
combined chlorine (calculated)
ORP
Temperature (as correction variable for pH and chlorine)

Advantages

Considerable cost savings through integrated videographic recorder as standard and distributed modular design:
With only one central unit, up to 16 filtration cycles can be regulated and controlled.
The simplest operation because of the large illuminated colour display and automatic selection of measurement
range. Simple wiring by means of coded ready-made socket connections.
High degree of reliability thanks to extensive monitoring functions such as sensor monitoring and dosage time limitation.
Visualization* without special software using a normal PC and optional integrated webserver.

Features

Simple installation: installation only needs one bus cable
No wiring errors because of coded plugs and sockets
Each ProMinent device connected is automatically recognised by the central unit and works according to the “plug and play” principle making installation and start up much easier.
Investment for the future: flexible and simple upgrade with additional modules
Up to 16 filtration cycles controlled by only one central unit saving costs
Integrated videographic recorder (optional) saving costs on a printer, ink and paper
Built-in visualization – An embedded webserver as standard allows you to communicate with the DULCOMARIN® II without any special software and only one PC with a LAN interface and a web browser.
The card reader: The built-in SD-card reader allows you to transfer measured data to a PC or to carry out software updates using a SD-card familiar to you from using a digital camera
Intuitive operation using a large colour display
Minimizing combined chlorine: depending on the concentration of the combined chlorine, ProMinent UV and ozone plants can be used to breakdown chloramines.
