GF Hycleen Flush

Automatic flushing for safe drinking water systems

Automated and recorded water exchange with stagnation flushing

Hycleen Flush automates stagnation flushing safely and precisely, thereby playing a key role in keeping drinking water hygienically safe in cold and hot water pipes. The valve ensures efficient compliance with modern hygiene standards by activating flushing cycles according to predefined parameters and recording them automatically. As a cost-effective and less invasive alternative to flushing stations, Hycleen Flush minimizes installation effort and interventions in existing systems. This demonstrably supports compliance with operator obligations and reliably prevents stagnation. The result: improved system performance in terms of safety, technology, and hygiene.


Greater safety and less effort with GF Hycleen Flush through automated flushing


Hycleen Flush ensures reliable drinking water hygiene through automated flushing. Its flexible applications, simple retrofitting, and quick commissioning significantly reduce hygiene risks, regulatory obligations, and operational workload, while automatic recording verifies safe system operation.

Areas of application for GF Hycleen Flush for hygienic flushing and shut-off

 


Hotels


Hospitals


Elderly and care homes ​

 


Schools, Kindergartens


Office buildings, Vacation homes

In buildings with highly fluctuating water usage and longer periods of stagnation due to vacations, seasonal factors, or regular renovation and non-use, the risk of stagnation and Legionella growth increases. Hycleen Flush addresses this challenge with automated flushing, simple installation, and comprehensive documentation. This results in hygienic water supply systems and significantly reduces the effort required by operators.

The system is particularly impressive for retrofits thanks to its uncomplicated and minimally invasive installation. It also saves water, reduces operating costs, and can be seamlessly integrated into existing building management systems. This makes it a reliable solution for planners, architects, engineers, and operators.
 

GF Hycleen Flush as shut-off valve

When used as a shut-off valve, Hycleen Flush provides an intelligent solution for protecting water-carrying systems. Pipes can be selectively shut off, monitored, and automatically closed when needed. The application is available in DN 15 and DN 20 and is ideal for tight installation spaces. States are recorded and can be controlled via app or building management system. This ensures clear control and a high degree of operational safety. 


Shut-off for every scenario

Hycleen Flush can be used not only as a flushing valve but also as a fully functional shut-off valve. It can be flexibly controlled via the app, sensors, or the building management system. The function is selected during the commissioning phase, as installation locations within the building may vary from application to application. This enables intelligent management of water flows, adaptive response to environmental conditions such as frost or leaks, and targeted enhancement of operational safety.

Benefits of GF Hycleen Flush as shut-off valve

Shut-off for every scenario

  • Frost protection

  • Closes and drains the pipe when temperatures drop below 5°C

  • Access control

  • Protects against misuse and vandalism at public water points

  • Loss and damage limitation 

  • Helps prevent damage in the event of pipe bursts or prolonged water usage

  • Smart irrigation

  • Time-controlled watering based on a programmed weekly schedule

Control and access

  • Manual and remote operation

  • The valve can be operated both on-site and remotely via the app, with automation options

  • Building Management System (BMS)

  • Control via Modbus for seamless system integration

  • Personalized access control

  • ​System integration allows assignment of individual access rights, ensuring that only authorized personnel can operate the valve
