Application advantages: Simple and standard-compliant filling of any heating system with the required technical water. The cartridge's plug and play system regulates all the relevant parameters to fill the system in accordance with the standards, making installation simple. No additional devices are required to monitor the quality of the technical water during filling. The current consumption of the cartridge is displayed using the high-quality colour change ion exchange resin. In addition to the normal PURE S cartridge, a practical wall bracket including connecting hose is also included in the scope of delivery. Ideal for the customer to top up independently.
