The Hycleen Automation System by GF Piping Systems offers a sophisticated package for the automation of drinking water installations. Sensors and controllers integrated in the valves log the required data. The master controls all processes and supports with its applications a hygienically impeccable, optimized drinking water installation through logging and reporting. The synchronised components are wired to each other in a way which is easy to handle.
Hycleen Automation System - Revolutionizing Sanitary Automation Processes and Securing Safe Supply of Drinking Water
The Hycleen Automation System is a state-of-the-art circulation control system that is particularly quick and easy to install and commission. It allows for all system data to be logged, evaluated and displayed on a 10-inch touch screen. All system data can conveniently be monitored remotely; status information and unusual occurrences are reported through push messages.

Safe and Hygienically Optimized Drinking Water Installation
Hycleen - 4 steps to safe drinking water hygiene
With its Hycleen Automation System, GF Piping Systems supports planners, installers and property operators in a variety of ways to implement the concept of „Hycleen – 4 steps to safe drinking water hygiene“.
The central data storage and control through the master, the powerful LegioTherm valves and sensors as well as the easy-to-operate software and the smart LegioTherm applications make it possible to automate important hygienic precautions.




Temperature-Sensitive Hydraulic Alignment
Especially in larger hot water distribution systems – e.g. in hospitals, hotels, nursing homes – stagnation, rough surfaces and temperatures below 50 °C can promote the formation of biofilms and thus the proliferation of Legionella. That is why the prevention of Legionella, sufficiently high temperatures and regular water exchange are of paramount importance.
Automatic Flushing
Depending on Temperature, Stagnation Time or Programmed
If water stagnates over a longer period, bacteria can multiply in it until a dangerous concentration is reached. If the entire volume in the drinking water distribution (cold and hot water) is exchanged within three days, the bacteria are flushed out of the drinking water installation and the bacteria concentration drops to a harmless level.
The Hycleen Automation System allows automatic flushing of cold and hot water supply lines depending on the temperature or a specific time of day (timer).

Valve
The LegioTherm 2T and LegioTherm K valves, together with the master, are at the heart of the Hycleen Automation System. Water temperature readings are permanently taken by the valves; the values are passed on to the master. The valves are activated dependent on preprogrammed parameters. During commissioning, all valves are automatically detected by the master by their ID.
