Commercial Softener RF1465SO1
A high-capacity, professional-grade water softener for demanding residential, commercial and light-industrial use, built around a 14 x 65 inch pressure tank with a CE 1 inch control valve and a large 146 litre overflow-protected brine tank.
About the Commercial Softener RF1465SO1
The Commercial Softener RF1465SO1 is a complete softener assembly for demanding residential, commercial and light industrial use. It is built around a 14 x 65 inch pressure tank with a CE 1 inch control valve, and a large 146 litre brine tank with grid, well, valve and overflow set.
You choose the media on order: Ecolite Soft SAC resin or Ecomix A, C and P. The valve regenerates on a delayed, immediate or volume basis, and it can run in twin or duplex and control two external devices.

Typical applications
Who the Commercial Softener RF1465SO1 is for
- Estates with hard water.

How the Commercial Softener RF1465SO1 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 RF1465SO1, the CE 1 inch valve regenerates on a delayed, immediate or volume basis. The brine tank has a grid, well, valve and overflow set. A meter assembly, distributor sets, fittings and a power supply are part of the assembly, and the datasheet lists the valve menu languages as EN, DE, FR and UK.
The Ecolite Soft SAC resin is a polystyrene DVB gel with sulfonic groups in sodium form, with a minimum exchange capacity of 1.9 eq/L, 16 to 50 mesh, a maximum temperature of 120 °C and a regenerant of 8 to 20% NaCl. The datasheet does not give a flow rate, so we size the unit to your demand at survey.
Which one should you choose?
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
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
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
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
You want a ready-loaded commercial softener: 75 L of resin, 3.5 m3/h continuous and 15 m3 between regenerations.
Commercial Softener RF1465SO1
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
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 RF1465SO1 is supplied as a complete assembly with the tank, valve, brine tank, meter assembly, distributor sets, fittings and power supply. You specify the media, Ecolite Soft SAC resin or Ecomix A, C and P, on order.
The datasheet lists a 230 V supply at 30 W. It does not list the inlet pressure, connection sizes or weight, so we confirm these for your site at survey. Two external devices can be connected, and twin or duplex operation is available.
The survey is chargeable and is credited back if you go ahead.
Commercial Softener RF1465SO1 questions answered

What media can it use?
Ecolite Soft SAC resin or Ecomix A, C and P. You specify which on order.
How does it regenerate?
Delayed, immediate or volume-based, controlled by the CE 1 inch valve.
What power does it need?
230 V at 30 W.
What languages is the valve menu in?

Can I run two units together?
Yes. The datasheet lists twin or duplex operation.
Can it control other equipment?
Yes. It can control two external devices.
What flow rate does it give?
The datasheet does not give a flow rate. We size the unit to your demand and your water at survey.
Which softener should I choose?
If you need a set flow figure on the datasheet, look at the Regal 500 (6.12 m3 an hour) or the Regal 750 (3.5 m3 an hour continuous). We compare options for your site 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.

Supplied, installed and serviced across the UK
Across most of southern and eastern England, mains water is very hard. Rain filtering through chalk and limestone dissolves calcium and magnesium, and that scale coats heating elements, so we size every system to your supply and your equipment.
