Twin and Duplex commercial softeners

Twin or duplex water softening systems include two tanks to treat an increased volume of water simultaneously and supply it continuously around the clock. In the Ecosoft online shop, you can order units with and without media at the most reasonable prices. 

Twin or duplex water softeners are designed to treat hard water. Their operating principle is similar to a traditional softener and is based on the use of the media that removes dissolved calcium and manganese from the water and improves its taste. Also, it protects appliances and equipment from limescale build-up that typically results in their premature failure. 

The difference lies in the number of tanks. Duplex models have two pressure tanks and a separate brine tank, which increases the productivity of a unit. In both pressure tanks simultaneously or successively, the hard water is forced through resin beads that exchange the unwanted minerals for sodium ions. When the resin is saturated with calcium and manganese, it is rinsed with salt water from a brine tank. After the regeneration, the wastewater is sent to the drain.

Twin and duplex systems use two simultaneous flows that enable the purification of a larger quantity of drinking water at a time. Such units provide homes with large families or commercial facilities with a sufficient, constant water supply. The flow rate may vary from 2.1 to 7.6 m³/h. There are models with regeneration control, which can launch the process immediately or delay it according to the water volume. It would be better to have settings to set the cycle of regeneration stages.

The menu should be comprehensive and available in various languages so that users can cope with the instructions regardless of their origin. Also, it makes sense to think about the possibility of an alternative use. In our catalogue, there are units without media, which can be accomplished with ion-exchange resin or the ECOMIX media to remove iron from the water. Thus, you do not need to buy an iron softener in addition, as a duplex system features this option too.

Such descaling systems are widely used by small businesses, like cafes, hotels, or restaurants, to provide a constant water supply for food processing, laundries, dishwashers, etc. Water softeners with two tanks better meet the requirements of the commercial sector due to comparatively high productivity. Still, they can be installed in residential buildings and small industrial enterprises.

Before choosing a duplex soft water system, you should know the hard water quality to meet the softener's requirements, which commonly define a hardness level, iron, manganese, and ammonium content. Also, the expectations for productivity are of significant importance. You should consider:

• operating flow rate rather than maximum;
• volume of pressure tanks (there are units with tanks of up to 21 x 62);
• volume of a brine tank (it can include 125 L, 378 L, etc.);
• quantity of resin needed to treat the water (the available range is from 50 L to 340 L).

We recommend paying attention to an operation alternative mode when one tank treats water while the other is at the regeneration stage or stands by, which provides a constant flow. Other settings are also available, like a simultaneous connection of two external devices. The choice depends on how much water is consumed. If you do not need the highly efficient treatment, you can look through our assortment of domestic iron softeners at a lower cost.

It is beneficial to buy Ecosoft duplex water softening systems and reverse osmosis filters for higher purification, as we deliver high-quality solutions manufactured at the ISO 9001-certified factories within the strict international standards. Our products stand out with steady filtration performance and reduced energy consumption. We offer a wide range of parameters to meet the versatile demand. Tailored offers, local support, and fast delivery are also available.
