The single-tank strategy
Summer use:
- Efficient watering: Whether manual watering with a hand-held lance or fully automated plant care using the Fiedler watering arm (FGA) – ensure water-saving and precise watering of your green spaces.
- Powerful surface cleaning & flushing: Use the Fiedler flushing bar or adjustable flushing nozzles for thorough cleaning of roads. For squares and pavements, our scrub deck or surface cleaner is the first choice.
- High-pressure & hot water cleaning: For stubborn dirt, our high-pressure systems, combined with a hand lance and a wide range of attachments and nozzles, offer the perfect solution. Need more power? Then our hot water systems are the right choice.
- Ecological weed control: Choose sustainability! With our hot water method, you can destroy weeds effectively, deep down and without chemicals – completely without the use of herbicides.
- Specialised washing brushes: Whether tunnel washing brushes, guide post washing brushes or universal brushes – the FTS reliably supplies your attachments with clean water for sparkling results.
Winter use:
- Highly efficient brine spray system: Convert the FTS tank system into a brine spray system for winter maintenance using our brine booms.
The 10 most important FAQs about Fiedler FTS tank systems
An FTS (Fiedler Tank System) is a modular body system for municipal utility vehicles and flatbed trucks. It is primarily used for watering green spaces, high-pressure cleaning, cleaning with wash booms or wash nozzles, and for the use of surface cleaners, scrub decks or various washing brushes. It is also ideal for weed control using a hot-water system. Thanks to its modular design, the capacity can be precisely adapted to the specific carrier vehicle.
Our systems are brand-independent and optimised for virtually all standard municipal narrow-gauge vehicles, vans, tractors and lorries (e.g. Multicar, Unimog, Hansa, Kärcher, Ladog, Reform, MAN, Atego, Kubota, Valtra, etc.). Thanks to the flexible modular design, we can tailor the centre of gravity and axle load distribution perfectly to your vehicle.
We use high-quality polyethylene (PE) because it offers significant advantages over steel or GRP:
Higher payload: Its low weight allows for the transport of significantly more water.
Extreme robustness: Our PE is impact-resistant, UV-resistant and far superior to GRP tanks in terms of durability.
Maintenance-free: The material is 100% corrosion-free and therefore extremely durable.
Our systems require very little maintenance. As they are made from PE plastic, there is no need for any form of corrosion protection on the tank. Maintenance is essentially limited to cleaning the filter cartridges and visually inspecting the pump units, as well as ensuring the system is properly winterised (drained) to prevent frost damage to the pipes.
Depending on the application, we offer a range of configurations:
- Low-pressure pumps: Ideal for watering plants and trees.
- Medium-pressure pumps: They offer the perfect balance of water flow and pressure for efficient surface cleaning and professional grounds maintenance
- High-pressure pumps: Perfect for cleaning traffic areas (e.g. with a flushing boom) or for sewer cleaning.
Power is supplied either via the vehicle’s hydraulic system, the PTO shaft, a separate auxiliary engine or electrically.
The FTS system serves as the centrepiece for various attachments and options:
- Spray booms and long-range nozzles
- Flushing booms and flushing nozzles for street cleaning
- Various hose reels for manual watering or high-pressure cleaning
- Sewer flushing units
- Various washing brushes
- Surface cleaners and scrubbing decks
- Hot water system for weed control
- Brine spray system for winter maintenance
Fiedler stands for ‘Made in Germany’ and decades of experience in municipal technology, worldwide. Our systems are characterised by exceptional durability, guaranteed availability of spare parts and seamless integration into your existing vehicle fleet. We do not supply a standard solution, but a system optimised for your fleet.
