ABOUT US
Every year, Karl Spiegl GmbH & Co. KG builds around 1000 water treatment systems in all sizes and areas of application.
Right from the start, the company has dealt with drinking water treatment for private households and objects, as well as with the treatment of process water in the industrial sector.
Continuous development activities gradually opened up further applications.
Membrane technology, with a focus on "reverse osmosis", has been an integral part of the production program for 20 years. In the last 15 years, the program has been expanded to include industrial applications in the high-demand area.
The main activities in recent years have been larger systems and applications with special requirements in terms of product water quality with a focus on the microbiological condition of the water.

WATER TREATMENT PLANTS

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 high flexibility, high operational reliability and short delivery times.
The optimal solution depends on the application, the required water quality and water consumption. Our team of specialists will be happy to answer your questions about solutions for pure water treatment.
Only with us.
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.
