The ORBEN SERASTIL NKS, C and S series are refill cartridge systems in various sizes, with or without a system separator. They ensure optimal and standard-compliant treatment of replenishment water in accordance with VDI 2035 (as well as ÖNORM H 5195-1 and SWKI BT 102-1).

In the ready version, all series combine an automatic filling valve with a type BA system separator and a desalination cartridge as a complete treatment concept. The separation of both systems required in DIN EN 1717 in the event of short-term and permanent contact between the fresh water pipe and the service water installation (i.e. the drinking water network and the heating system) is thus fulfilled thanks to the integrated system separator. -> Blank space for drinking water, twice “is” in the last sentence

For easy and quick replenishment of supplementary water in accordance with VDI 2035 in hot water heating systems, for connection to an existing system separator.

Includes a water meter to document the amount of replenished water, ball valve and ORBEN high-performance cartridge with germ barrier and practical color change from blue to brown as a sign of wear.

The SERASTIL NKS series is available in UNO (with one), DUO (with a double cartridge) or QUATTRO (with two double cartridges).
