Water softening systems
Water softening systems for removing calcium and magnesium consist of a cation exchanger that exchanges calcium and magnesium for sodium. Softened water is used for steam boiler systems, district heating systems, laundries, cooling towers, rinsing and washing processes, dishwashing, etc.

Sensor-controlled water softening systems
Spiegl water softeners are equipped with a sensor to detect when the resin bed is exhausted. This feature is unique and patented by Spiegl. Intelligent water softener – triple sensors to indicate exhaustion at 33, 66, and 0%.

User-friendly control display
The reverse osmosis system has a robust, welded stainless steel pipe system that can withstand high water pressure. The low-pressure piping is made of PVC, PP, or PE.

Countercurrent regeneration
Countercurrent regeneration (UF) is a particularly gentle regeneration process in which operation takes place from top to bottom and regeneration from bottom to top. This allows regeneration to be carried out much more efficiently, saving 50% salt and wastewater while achieving the best soft water quality below 0.1 °dH.

Sensor-controlled water softening systems
Spiegl water softeners are equipped with a sensor to detect when the resin bed is exhausted. This feature is unique and patented by Spiegl.
Sensor-controlled water softeners only regenerate when the bottle is actually exhausted. In contrast, water meter-controlled systems regenerate according to a calculated value and not according to the state of exhaustion. After regeneration, the user-friendly touch panel can be used to check whether the regeneration was successful. In the event of an error, you receive an immediate notification and have time to react. In the event of an operational malfunction, e.g., salt shortage or low pressure during regeneration, we detect faulty regeneration or hard water breakthrough and protect sensitive technology such as reverse osmosis or boilers with an alarm.
The commissioning of a sensor-controlled system is more user-friendly, as no extensive capacities need to be calculated and safety is guaranteed. This means that the system can be put into operation easily and without complications.
Product overview
Our product range includes a wide variety of standard systems, all of which are developed and manufactured in-house.
The starting point is our modular standard system, which guarantees a high degree of flexibility and operational reliability. We can customize each solution to suit the customer's specific requirements and tailor it to the respective application by selecting the appropriate materials, devices, and control system.

Water softening systems for hot water
Fully automatic, volume-controlled water softening system for producing soft water with a residual hardness of less than 0.1° dH, using the neutral exchange process with a strongly acidic cation exchanger.
Regeneration is carried out with common salt. Regeneration is triggered fully automatically via quantity control. Manual intervention is possible. Regeneration can optionally be carried out with cold water from a separate supply.
Controls and automation
Spiegl GmbH offers a comprehensive range of PLC controls for our systems in the areas of filtration, ion exchange, membrane filtration, and CDI/EDI.
All controls are designed, developed, and programmed by our engineers. This guarantees flexible, functional software that is tailored to your needs. We offer hardware components from Siemens, Schneider, and Mitsubishi.
A central PLC control cabinet contains the pump control and supply, the HMI in the form of a touch panel, the CPU, and, depending on requirements, additional components such as frequency converters, transducers, rectifiers, and communication processors.
We would be happy to advise you on which solutions are suitable for you.
Why water softening?
Softening prevents limescale deposits, e.g., in pipes, steam boilers, district heating systems, hot water systems, heat exchangers, and cooling towers. The usual use of chemicals to bind calcium can be avoided. In other words, softening can optimize energy consumption in boilers and hot water systems, minimize chemical consumption, and extend the service life of installations and systems.
Do you need advice?
The optimal solution depends on the application, the required water quality and the water consumption. Our team of specialists will be happy to answer your questions about solutions for your water treatment solution.
