BWT Rondomat Duo - DVGW

Drinking water softeners

RONDOMAT DUO - DVGW Type 2 - 10

Quantity dependent controlled soft water pendular unit, with soft water short cycle generator, intelligent control electronics with control head and control device with ZLT-connection, individual setting of the raw water hardness at the press of a button, no additional system or pipe partition required, regeneration ends shortly before switching cycle, noticeable space-saving, integrated germ protection system, short and fast regeneration, optimal salt and flushing water consumption - independent of the prescribed water pressure. Scope of delivery: complete unit, hardness testing device.

Installation requirements:

• Nominal pressure 10 bar
• Operating pressure 2.5 - 8.0 bar
• Mains connection 230/50 - 60 V/Hz
• Protection class IP54
