Product Description

The demineralisation unit of the Honeywell NK300SE-VE facilitates the demineralisation of heating water according to VDI-guideline 2035, sheet 1 and 2. Lime scale and thereby caused damages and malfunction in hot water heating system (EN 12828) are avoided efficiently. The refilling combination fitted on the inlet and based on a BA-type backflow preventer protects the drinking water supply against back flow of heating water according to EN 1717.
