* Estimated consumption for the respective residential example system; not the maximum system capacity. For WAVE, the area of 1,000 m² is an arbitrary assumption. Basis for calculation: 50 m² per person, 150 liters per person per day, 365 days per year; rounded to 10 m³.

The specified operating ranges correspond to the manufacturer's technical application profile. The selection is based on the pipe diameter, system configuration, flow rate, and application.

Your Model Selection

Three pieces of information will help you determine the correct design.

01 / APPLICATION

Where is the device used?

Apartment, residential building, heating system, swimming pool, or industrial facility: Describe the water system and the desired area of operation.

02 / INSTALLATION

What type of line is available?

The pipe material, outer diameter, and a photo of the installation site will help determine the appropriate ferrite model and installation method.

03 / OPERATIONS

How is the water used?

Flow rate, consumption, and the layout of the piping system round out the selection criteria. Grubatec will review this information with you.

Frequently Asked Questions

Make an informed choice.

What is the difference between PURE and CARE?

Both devices have one channel, a type M ferrite core, and a control unit measuring 85 × 54 × 24 mm. PURE operates at 12 V and 3.5 W, while CARE operates at 15 V and 3.7 W. According to the manufacturers’ technical specifications, PURE treats limescale and rust; CARE also treats biofilm and algae.

What are the differences between PREMIUM, WAVE, HEALTH, and CLEAN DROP 2?

PREMIUM and WAVE operate at 24 V; WAVE has two channels, while PREMIUM has one. HEALTH and CLEAN DROP 2 operate at 48 V; CLEAN DROP 2 has two channels, while HEALTH has one. All four models use ferrite type L. Legionella and Pseudomonas are listed in the technical manufacturer's profile for HEALTH and CLEAN DROP 2.

How do I find the right device?

Key factors include the application, pipe material, outer pipe diameter, flow rate, the configuration of the water distribution system, and the desired coverage area. Please send Grubatec this information and, if possible, a photo of the intended installation site. The size of the building alone is not sufficient for a reliable design.

What does the maximum pipe diameter mean?

The values 33.7 mm for ferrite type M and 63 mm for ferrite type L refer to the outer diameter of the pipe. The nominal diameter (DN) and the inch specification are supplementary manufacturer specifications; the actual outer diameter must match the selected ferrite model. For larger pipes, Grubatec will determine the appropriate model.

How do you install the limescale protection device?

Signals are transmitted via ferrites attached to the outside of the existing water pipe. The pipe does not need to be cut open for this. The devices operate without salt or chemical additives; the natural minerals remain in the water. Installation and setup depend on the model selected and the accompanying instructions.

What are the displayed fuel consumption estimates based on?

The values have already been calculated for the respective living areas specified. The calculation assumptions are 50 m² per person, 150 liters of water per person per day, and 365 days per year. This results in 1.095 m³ per m² per year; the display is rounded to 10 m³. For WAVE, a hypothetical living area of 1,000 m² is used as an example. The values describe the consumption of an example system, not the maximum capacity of the unit. Commercial buildings, hospitals, hotels, swimming pools, and industrial facilities may have significantly different needs.
