The benefits of having two resin tanks
- Soft Water 24/7 – you will never run out of soft water
- Only regenerates when necessary – you will use less salt and you’ll never have to reset timers
- Enables a large capacity from a small softener – it could be installed under your sink
- One size fits all – you won’t need to upgrade or downgrade if your family situation changes
- Simple to disconnect, no electrical wiring – take it with you if you move and the guarantee stays with the unit
How an ordinary electric softener works
Ordinary softeners only have one resin cylinder, which requires an electrical supply to power a mechanical or computerised timer. The timer is needed to control the regeneration process. Single cylinder softeners cannot regenerate during the day whilst water is likely to be used, so they are regenerated at night. With this type of softener, if water is used during regeneration it will be hard. This process typically takes an hour or more in an ordinary softener and during this time no soft water is available. Neither can they use the full capacity of the resin because it could exhaust itself during the day and would produce hard water. To avoid this possibility they are programmed to trigger a regeneration when a proportion of the resin has been used, which is inefficient. In homes with a water tank in the roof or with a pressurised system, using water during regeneration will harden all of the stored water, hot or cold and it can take some time for the water to become completely soft again.
Twin cylinder softeners do not suffer this problem because, when one cylinder exhausts itself the other takes over. This uses the full capacity of the resin and the unit can regenerate at any time, even when water is being used in the house.
How our non-electric TwinTec softener works
The obvious difference between an ordinary softener and the TwinTec is the fact that our water softener has two cylinders as opposed to one. This makes the regeneration process much more efficient, as shown in the diagram below.
TwinTec uses the flow of water to operate the control module. This is why the softener can cope with fluctuations in water demand in any household, without the need to alter time clocks or computer controls.
The TwinTec caters for a household of 1-10 people and requires no programming or maintenance other than keeping it topped up with salt blocks. Rest assured that if you go away on holiday the softener will not waste water or salt by regenerating unnecessarily. It simply waits for you to return and start using the water again.
Simple, efficient and luxurious!
