VE300
Softening unit
for heating systems
Product specification sheet
Application
The softening unit of the Honeywell VE300 facilitates the softening of heating water. Limescale and thereby caused damages
and malfunction in hot water heating system are avoided
efficiently.
According to DIN EN 1717 the refilling combination NK300 have
to be fitted on the inlet to protect the portable water supply.
Special Features
• Intergrated water meter simplify the determination of cartridge
exchange
• Easy installation and exchange of cartridge without tools
• Constant connection with the drinking water supply in accordance with EN1717 by hose line or piping is possible in case
of using a NK300
Range of Application
Medium Water
Inlet pressure max. 6.0 bar
Suitable for heating systems with the following materials: steel,
copper, copper alloys and plastics.
Treated water has modified corrosive chemical parameters.
Conditioning by means of inhibitors is to be provided for separately.
