Code: 6282/OP 6282/OP2 6282/OP3 6282/OP4 6282/OP5 Choose variantProduct detailed description
Double Water Softener OP DUO 25-75 is a reliable solution for a constant supply of softened water, combining advanced control technology with efficient regeneration and flexible operating modes. Ideal for larger family homes, guesthouses, smaller hotels, and other facilities.
Continuous Supply of Softened Water
The dual water softener OP DUO 25-75 is designed for continuous operation without interruption for regeneration. With two pressure tanks containing filtering media and one tank for regenerating salt, it allows for a steady supply of treated water.
Pentair Autotrol 255/764 TWIN Control Valve with volumetric regeneration
Pentair Autotrol control valves use a unique system of camshaft and control flaps that are characterized by high reliability and durability. Thanks to modular construction, they are universally applicable for a wide range of applications.
Smart Control Unit Logix 764
This unit offers several levels of settings, the ability to adjust the timing of individual cycles, and a history mode. In case of a malfunction or downtime of one pressure tank, it automatically switches to simplex mode, allowing operation to continue with just one tank.
Advanced 7-Cycle Regeneration
The softener employs a 7-cycle regeneration with a second backwash and rapid rinse, optimizing salt usage and reducing hard water leakage. Mixing the filtering media after regeneration contributes to more efficient use of capacity and can reduce regenerating salt consumption by up to 10%.
Non-stop Operation
The Autotrol 255 TWIN valve is exceptional because each pressure tank has its own full-function valve, allowing for the creation of a double system. It offers 2 operating modes: alternating and parallel. Switching between these modes is done simply through the Logix 764 control unit.
Two Operating Modes for Maximum Flexibility
- Parallel Mode – both pressure tanks operate simultaneously, with regeneration occurring alternately so that one tank is always in operation.
- Alternating Mode – only one tank is active at a time while the other is ready for immediate use after the first tank's capacity is exhausted.
Practical External Bypass
The device is equipped with an external bypass with a 1” connection, allowing for easy outage of one or both tanks during maintenance or servicing.

| Flow Rate during Rinsing | 0.5 m³/h | 0.6 m³/h | 0.6 m³/h | 0.9 m³/h | 1.1 m³/h |
* Nominal flow rate when using alternating mode, where water flows only through one pressure tank.
** Nominal flow rate when using parallel mode, where water flows through both pressure tanks simultaneously. During the regeneration period (1 to 2 hours) of one of the pressure tanks, you must account for a reduction in flow by half. Once the regeneration is completed, the full capacity of both pressure tanks is available again simultaneously.
- Regenerating salt and filter media can be purchased at our e-shop.
- A pre-filter for mechanical impurities must be installed before each softener.
- It is necessary to have a connection to the sewer near the filtration system to drain the accumulated calcium, as well as iron and manganese, from the filtration system.
Installation and Service of the Device
Installation and transport will be provided by our own service technicians (we have 14 authorized service technicians across the Czech Republic and Slovakia). If you're interested, we would be happy to prepare a price quote for you. The installation cost depends on the difficulty and the materials used (connecting hoses, valves, etc.). If you are interested in installation, please let us know in the note section of the cart ("Enter a note for the seller").
We recommend carrying out service replacements regularly once a year. The cost of service replacement is 1,990 CZK + travel costs, which are charged as a flat rate of 590 CZK (for Prague and Brno 990 CZK) in cases where the technician's trip is combined with other installations or services along the way.
