FRANK FTW®-systems made of durable and environmentally friendly PE (polyethylene) enable the source collection and safe storage of drinking water. We use the best and most suitable materials for the production, for example DVGW-approved and KTW-tested PE materials. With the adaptable and configurable FTW®-modules - which are the coiled tubing process - we can build tubular storage tanks up to DN 3500. This has already enabled our customers to build FRANK drinking water storage tanks with a capacity of over 1200 m³ (equivalent to 1200,000 liters) successfully into operation. Due to the modular design of the system tanks, our FTW®-systems, systems for drinking water production and storage can be adapted to customer requirements. The factory pre-assembled modules and components, facilitate on the construction site allow due to their low weight very short assembly times, which means the tanks can usually go short termed in operation. Another advantage of FTW drinking water tanks made of PE is the smooth surface with low incrustation, as well as very good and easy cleaning.
Summing up: FTW®-structures can be build ecologically, economically and fast. After a service life, estimated far more than 100 years, FTW components can be easily recycled.
In addition to drinking water storage, our PE tubular storage tanks can also be used to store fire-fighting water. Alternatively, we offer our resistant PE linings for new construction and for the coating of concrete water tanks, named HydroClick® and AGRUSAFE®.
