It gives up to 6.12 m3 an hour of service flow at a 1 bar pressure drop. It is supplied as a media-ready assembly: the tank is delivered without media, and you choose Ecomix or cation exchange resin on order. The datasheet describes it as domestic and light commercial. ## Key features - Up to 6.12 m3/h of service flow from a 10 x 54 inch pressure tank - CE 1 inch control valve with volume-based regeneration: delayed, immediate or both - Separate 125 L brine tank with overflow protection - Media-ready for Ecomix and cation exchange resin - Twin, duplex or up to 6 systems on one controller - Multilanguage menu and two external device connections ## Specifications | Item | Value | | --- | --- | | Model code | RF1054CE | | Service flow (1 bar drop) | 6.12 m3/h | | Backwash flow (1.7 bar drop) | 6.12 m3/h | | Pressure tank | 10 × 54" · 63 L | | Brine tank | 15 × 17 × 36" · 125 L, overflow-protected | | Control valve | CE 1" | | Regeneration | Volume-based: delayed, immediate or both | | Media | Supplied without media: Ecomix or cation exchange resin, specify on order | | Inlet pressure | 2 to 6 bar | | Feed temperature | +4 to +30 °C | | Power | 230 V, 50/60 Hz, 30 W | | Inlet / outlet | G 1" | | Brine / drain | G 3/8" / G 3/4" | | Dry weight | 15 kg | | Connection height | 1435 to 1540 mm | ## Who the Regal 500 is for - Domestic sites that need more softening demand than a cabinet softener handles. - Light commercial sites with higher softening demand. - Installs where quick installation matters: the datasheet describes it as a ready set. - Sites that want to choose between Ecomix and cation exchange resin. - Installs that may grow: twin, duplex or up to 6 systems can run on one controller. ## Where it is used - Domestic - Light commercial ## How it works In general, a water softener swaps the calcium and magnesium that cause hard water for sodium, using a bed of ion exchange resin. When the resin is used up, the softener regenerates with salt brine and rinses the hardness away to drain. In the Regal 500, the CE 1 inch valve regenerates by volume: delayed, immediate or both. In general, a delayed regeneration waits for a set time, and an immediate one starts as soon as the volume is reached. The valve menu is multilanguage. The datasheet gives a service flow of 6.12 m3 an hour at a 1 bar pressure drop, and a backwash flow of 6.12 m3 an hour at 1.7 bar. The capacity between regenerations depends on the media you choose and on your water, so we work it out at survey. ## How it compares The Regal range runs from under-sink cabinets to twin alternating vessels. The right one depends on how much soft water you need, and how fast. - [Regal 100](https://sovereignwater.co.uk/products/regal-100-water-softener): You have **limited space under the kitchen sink** and want a cabinet softener: **10 L of resin**, 1.0 to 1.2 m3/h. - [Regal 150](https://sovereignwater.co.uk/products/regal-150-water-softener): You want **a little more capacity under the sink**: **15 L of resin**, 1.3 to 1.5 m3/h and 3 m3 between regenerations. - [Regal 200](https://sovereignwater.co.uk/products/regal-200-water-softener): You want **the most capacity in the cabinet range**: **20 L of resin**, 1.6 to 1.8 m3/h and 5 m3 between regenerations. - Regal 500: You need **a floor-standing softener with a separate brine tank** and up to **6.12 m3/h** of service flow, with the media you choose. - [Regal 750](https://sovereignwater.co.uk/products/regal-750-water-softener): You want **a ready-loaded commercial softener**: **75 L of resin**, 3.5 m3/h continuous and **15 m3** between regenerations. - [Commercial Softener RF1465SO1](https://sovereignwater.co.uk/products/commercial-softener-rf1465): You want **a 14 × 65 inch tank** with a CE 1 inch valve and a large **146 L brine tank**, with your choice of resin or Ecomix. - [Regal Twin 3672](https://sovereignwater.co.uk/products/regal-twin-3672): You need **soft water that never stops**: two 36 × 72 inch vessels working in turn, with **18.2 m3/h** of service flow. ## Installation and servicing The Regal 500 connects with G 1 inch inlet and outlet. The brine connection is G 3/8 inch and the drain is G 3/4 inch. The connection height is 1435 to 1540 mm and the dry weight is 15 kg, before media and water. The datasheet lists a 230 V, 50/60 Hz supply at 30 W, an inlet pressure of 2 to 6 bar and a feed temperature of +4 to +30 °C. The media is not in the assembly: you specify Ecomix or cation exchange resin on order, and we quote it with the unit. Two external devices can be connected to the controller. The survey is chargeable and is credited back if you go ahead. ## Questions and answers ### What flow does the Regal 500 give? 6.12 m3 an hour of service flow at a 1 bar pressure drop. ### Does it come with resin? No. It is supplied as a media-ready assembly without media. You specify Ecomix or cation exchange resin on order. ### How big are the tanks? A 10 x 54 inch pressure tank (63 L) and a 15 x 17 x 36 inch brine tank (125 L) with overflow protection. ### How does it regenerate? By volume, delayed, immediate or both, controlled by a CE 1 inch valve. ### What does the multilanguage menu mean? The valve menu can be set to different languages, so the controller is easy to read on site. ### Can I run more than one? Yes. The datasheet lists twin or duplex operation, or up to 6 systems on one controller. ### What power does it need? 230 V, 50/60 Hz at 30 W. ### What connections does it have? G 1 inch inlet and outlet, G 3/8 inch brine and G 3/4 inch drain. ### What pressure and temperature can it take? An inlet pressure of 2 to 6 bar and a feed temperature of +4 to +30 °C. ### Regal 500 or Regal 750? The Regal 500 has a higher service flow (6.12 m3 an hour) and you choose the media. The Regal 750 comes loaded with 75 L of resin and gives 3.5 m3 an hour continuous with 15 m3 between regenerations. We size from your water and use at survey. ### Do you supply and install it? Yes. We supply and install it. The survey is chargeable and is credited back if you go ahead. ## Related products - [Regal 750](https://sovereignwater.co.uk/products/regal-750-water-softener): A ready-loaded softener with 75 L of resin. - [Commercial Softener RF1465SO1](https://sovereignwater.co.uk/products/commercial-softener-rf1465): A 14 × 65 inch tank with a 146 L brine tank. - [Regal Twin 3672](https://sovereignwater.co.uk/products/regal-twin-3672): Twin alternating, for soft water that never stops. ## Downloads - [Regal 500 datasheet (PDF)](https://sovereignwater.co.uk/datasheets/regal-500-water-softener.pdf) ## Contact - Request a quote or a site survey: https://sovereignwater.co.uk/contact - Email: sales@sovereignwater.co.uk - Phone: +44 20 8050 2115
