Adriatica 22 L water softener – Fleck 5600 SXT or 8200 Electronics valve
Adriatica 22 L: single-tank softener, 22 L resin, 80 kg salt tank, by-pass and mixing. Choice of Fleck 5600 SXT (Pentair) or 8200 Electronics valve. CE, NSF, ACS, RoHS certified. By DIMM.
Overview
The Adriatica 22 L is a single-tank (monobloc) water softener that houses the resin bottle directly inside the salt tank: one unit, a smaller footprint than a classic twin-tank. Its 22 litres of resin suit medium to large households and high-demand installations. The body is moulded in reinforced injected polystyrene with side stiffeners, keeping its rigidity even with a full salt tank.
This version is offered with a choice of two volumetric electronic valves: the market reference Fleck 5600 SXT (Pentair) or the new 8200 Electronics. Both share the same hydraulics and flow performance — the choice comes down to the interface, the design and commercial positioning.
Key points — Single-tank 22 L resin · salt tank up to 80 kg · dual safety by-pass + mixing valve · food-grade ion-exchange resin · choice of Fleck 5600 SXT or 8200 Electronics valve · CE, NSF, ACS, RoHS certified.
Two valves to choose from
Fleck 5600 SXT (Pentair)
The Fleck 5600 SXT volumetric electronic valve is a market benchmark: reliable, simple to set up and known for its longevity. Wide LCD screen with blue backlight, 48-hour power-failure backup, full front-panel access to all settings, separately adjustable cycles, co-current or counter-current brining, 4 modes (immediate or delayed volumetric, delayed or weekly timed) and optional double backwash.
8200 Electronics (new generation)
The 8200 Electronics carries the proven Pentair/Fleck 5600 SXT technology in a modernised housing. Precise volumetric regeneration, a more legible backlit LCD screen, protected electronics that keep settings during a power cut, and optimised hydraulics (lower water and salt use per cycle). It remains 100% compatible with existing installations and enhances the look of the install at the customer's home.
