How it works
How Flow Loop works
Recirculating shower technology for professional shower facilities
Flow Loop is an intelligent shower system that recirculates the warm shower water while the user showers. When the LOOP function is activated, a small amount of water collects on the floor, after which the system begins to recirculate the water through the shower.
The water is filtered and UV-purified in a continuous loop, preserving the shower experience while significantly reducing the use of new water and energy for heating.
The user can switch between traditional shower mode and LOOP mode. This makes the solution flexible in professional environments where user experience, operational reliability, and resource savings need to work together.
Recirculation
The water is treated in several steps
When the LOOP function is active, several technical functions work together to ensure stable operation and high bathing water quality. The water is collected from the shower floor, passes through filtration and UV purification, and is then sent back through the shower.
The process takes place continuously during the shower and does not require the user to significantly change their shower behavior. Flow Loop makes it possible to reduce consumption in professional shower facilities without compromising comfort.
UV purification: UV purification is a central part of the water treatment. UV light eliminates 99.999% of bacteria, viruses, and microorganisms in the recirculated shower water.
Microfilter: The microfilter captures smaller particles in the water before it is sent back through the shower. This contributes to a stable and clean shower experience during use.
Pre-filter: The pre-filter is located at the intake unit and captures larger particles before the water is passed on through the system for recirculation.
Intake unit: The intake unit is placed close to the floor and contains a sensor that detects whether there is enough water to start recirculation. When there is approximately 6 mm of water on the floor, the system can begin recirculating.
High flow
Resource savings without reduced user comfort
Flow Loop is developed for professional environments where water and energy consumption need to be reduced without compromising the user experience.
When the water is recirculated, the system can deliver up to 12 liters of water per minute through the shower. This provides a powerful and stable water flow while reducing the need for new water and heating.
The combination of high flow, stable temperature, and lower resource consumption makes Flow Loop relevant in environments where user acceptance is important — such as hotels, housing associations, businesses, and other shower facilities with regular use.
Maintenance
Developed for simple operation and service
Flow Loop is designed to require limited maintenance. The filter must be changed at fixed intervals, and the system must run a system rinse that helps keep the shower in stable operation.
For professional installations, fixed service procedures are important to ensure operational reliability, water quality, and a consistent user experience.

Recommendation
Flow Loop as a concrete sustainability initiative in professional employee facilities
At a major Danish company, Flow Loop is installed as part of the work to reduce the environmental footprint of daily operations. The solution has been highlighted in both the annual report and DGNB documentation and serves as a concrete example of how shower facilities can be included in ESG work, resource savings, and more sustainable employee facilities.
