Safe and efficient system

The BLUELINE filter cartridge produces demineralized water from normal tap water (also deionized or fully desalinated water or VE water) and inputs it with a deposition and corrosion protection.
The cartridge contains the proven LIQUIPURE ion exchanger mixed bed resin and a PROTABS Clean & Safe tablet with special corrosion protection for copper and aluminum alloys by the active ingredient tolyltriazole. The mixed bed resin removes all dissolved ingredients (ions) from the flowing water. The color change indicates when the capacity of the resin is reached. The tablet gradually dissolves and releases its active ingredients into the water. Used cartridges can be easily disposed of via normal household waste.
The BLUELINE fitting has Gardena connectors as standard, so that it can be connected to the heating system with appropriate couplings and hose lines. Other connections, adapters and other accessories (e..B. system disconnectors, if not already available) are available in the shop or on request.

Easiest application

The BLUELINE filter fitting is simply inserted into the filling hose of the heating system (standard with Gardena system). Via the filling valve on the heating system, VE water can now be directly refilled into the heating circuit with deposition and corrosion protection agents (optionally also pure VE water with LIQUIPURE cartridge).
The cartridge is easily interchangeable and displays via a color indicator when it is burned.
