20 Litre Duplex Commercial Clack Softener Flow Rate 800 litres per hour(835)
Our commercial Duplex water softener range of products are the ideal solution for applications that require consistent water flow
Whilst one tank performs a regeneration the second tank continues to supply softened water producing unrivalled daily supply.
Duplex softeners use high quality vessels and superior softening resin which reduces the amount of salt needed for regeneration. The units are controlled with a multi-port valve on top of the vessel allowing automatic regeneration at a given time or after a metered quantity of water is used.
A separate brine tank is included which sits next to the vessel.
