DI cartridge PUROFILL

Demineralisation system for initial filling or refilling of heating systems

Similar to VES cartridge p10

Desaline PUROFILL is a demineralisation cartridge (de-ionisation cartridge) for treatment of the filling or refilling water for central heating systems. Due to the deionisation of the central heating filling water the risk of damages or loss of efficiency caused by limescale is avoided and the threat of water side corrosion is lowered. The use of PUROFILL complies with common European guidelines (such as VDI 2035, SWKI or ÖNORM H 5195-1) for heating system make-up water treatment.

By the demineralisation process with PUROFILL lime and corrosive substances, such as chlorides and sulphates, are reliably removed from the water. This makes the demineralised water treated with PUROFILL an ideal central heating filling water, as in addition to a low water hardness the total salt content and thus the electrical conductivity is low.

With the PUROFILL water filter system the generation of demineralised water for filling heating systems is a simple process for the installer.

The filling water is simply passed through the PUROFILL demineralisation cartdridge before entering the heating system. During this process dissolved salts are removed from the water by a special ion exchange resin. This results in a continuous demineralisation of the filling water during the filling of the central heating.

  • Reusable cartridge – PUROFILL can be regenerated anytime after exhaustion by a simple replacement of the mixed bed resin.
  • Flexibility – PUROFILL can be used both for the initial filling and refilling of all central heating systems.
