Prestige Duplex Commercial Water Softener 20-100 Litres
Duplex softeners are ideal for sites with varying water demand or for applications where a continuous and uninterrupted supply of softened water is required. The twin vessel configuration allows for one resin vessel to always be in service whilst the other is in regeneration or standby thus guaranteeing 24/7 soft water production.
Duplex water softeners are available in a range of sizes, from 20 litres up to 100 litres making them ideal solutions for when moderate amounts of softened water is required on a 24/7 basis. Hard water contains magnesium and calcium ions, which are responsible for causing scale. This scale can cause pipes to clog, unsightly crusting and marks on faucets and shower heads, as well as cause appliances such as dishwashers, washing machines and boilers to have reduced effectiveness and lifespan.
They are great solutions for large factories, agricultural applications, cooling towers and laundries where softened water is needed 24/7. Duplex softeners are two softener tanks working the exact same way as a simplex water softener. However, when one of the tanks needs to go into regeneration, the second tank takes over softening the water whilst the first goes through the regeneration process. When the second tank then requires regeneration, they switch again, and so on. This process is called Service and Standby and enables you to have a constant supply of softener water, rather than having “downtime” during the regeneration process.
Typical applications for this style of water softener would be:
- As a pre-treatment to water purification equipment such as Reverse Osmosis
- Large Scale Boiler Feed
*Comes with Resin but no salt*
