Softening and demineralisation modules for make-up water

Modules for the softening or demineralisation of make-up water according to VDI 2035 Bl. 1 / SWKI-BT-102-1 / ÖNORM H5195-1 to protect heat generators and waterborne heating systems without aluminium components from calcium deposits. For systems with aluminium components a version with full demineralisation is available. Pre-mounted unit features a softening device filled with a high-grade ion exchange resin, and a 25 µm fine filter.

Features and Benefits

Easy installation

Compact pre-mounted unit for use with all types of systems. Can be connected quickly to a backflow preventer and a TecBox with flexible hoses. Easily exchanged once lifetime has elapsed.

Filter with transparent enclosure

Visible filter with 25 µm mesh size prevents dirt and resin from entering the system.

Energy savings due to reduction in calcium deposits

Less scale deposits on the hottest surfaces in the system lead to increased boiler efficiency and thus lower energy use.

Make-up water limitation

Automatic limitation of make-up water with the help of the PNEUMATEX BrainCube Connect control unit.

Applications

Softening or full demineralisation of the make-up water in cold and hot water systems without aluminium components.

Functions

Softening/demineralisation of the make-up water and filtering.
