Demineralization cartridge small (M) WATER PURE H2O 1500004290
Demineralization of heating systems – protection and compliance with standards
The water used to fill heating systems is crucial for their reliability and longevity. According to VDI, SWKI and Ö-Norm guidelines, preliminary water treatment is essential to prevent scale formation and corrosion. Even with water of low hardness, modern devices – such as gas boilers, heat pumps or solar installations – are susceptible to damage caused by mineral precipitation. PURE H₂O demineralization cartridges from ROTHENBERGER are a solution that allows for quick and easy filling of heating systems with water that meets the VDI 2035 standard.
These cartridges are ideal both when commissioning new installations and when servicing existing ones. They allow the removal of harmful minerals from the filling water, thereby protecting the system components from damage. The Plug & Play system independently regulates all important parameters, delivering technical water in accordance with applicable standards. This means there is no need to use additional devices to test water quality during filling.
Simple installation and consumption control
PURE H₂O demineralization cartridges are distinguished by their ease of installation and use. The Plug & Play system minimizes the time required to prepare water for filling the heating system. In addition, the high quality of the ion exchange resin allows for visual monitoring of cartridge consumption – a change in the color of the resin indicates the need for replacement. This simple solution avoids problems related to improper water treatment and ensures continuous protection of the heating system.
Advantages in practice
- Compliance with standards: Filling heating systems with water meeting the requirements of VDI 2035, SWKI and Ö-Norm standards.
- Easy installation: The Plug & Play system eliminates the need for additional devices and complicated procedures.
- Quality control: No need to test water quality after using the cartridge – everything is regulated automatically.
- Visual consumption control: A change in the color of the ion exchange resin indicates the need to replace the cartridge.
- System protection: Preventing the formation of mineral deposits, corrosion and sludge in pipes, which extends the life of the heating system.
- Versatility: Can be used in various types of heating systems – from gas boilers to heat pumps and solar installations.
This demineralization cartridge (size M) is a replacement/spare part, intended for use with the ROTHENBERGER PURE H₂O system. It provides effective water treatment and protection of the installation against the negative effects of hard water and the minerals it contains.
