Commercial Salt Free Scale Inhibitors

Price range: £170.00 through £1,480.00 Incl. VAT

Our Commercial Salt Free Scale Inhibitors utilise tried and tested template-assisted crystallisation (TAC) technology to prevent limescale formation in pipework, heating elements and outlets. Considered an eco-friendly alternative to ion exchange water softeners these low-maintenance systems require no electricity, no salt top-ups and no access to a drain. Suitable for both point-of-use and point-of-entry applications, these systems are commonly found in commercial settings such as hotels, offices, restaurants and cafes to prevent limescale build-up.

COMMERCIAL SALT FREE SCALE INHIBITORS

Versatile Salt-Free Limescale Inhibitor

As an easy-to-install and versatile alternative to a water softener these salt-free systems provide a ‘fit-and-forget’ solution to preventing limescale build-up in a commercial premise, or at the point of use (eg; on the feed to machinery). Suitable for flow rates up to 85 litres per minute, each size features a built-in bypass with threaded inlet/outlet connections allowing for a straightforward installation. Similar to a water softener, these systems will also work to clear existing limescale deposits over time without needing to be topped up with salt. Requiring very little maintenance the media has a lifespan of 2-3 years for point of entry or 1 year for point of use, with refill packs costing less on average than running an ion-exchange water softener for the same period.

An Excellent Salt Free Water Softener Alternative
These systems work by converting scale-forming molecules such as calcium and magnesium into inactive micro-crystals which float freely through pipes and heating systems without sticking to surfaces. The chemistry of the water remains unchanged, meaning people can still enjoy mineral-rich drinking water without the associated problems of hard water. This technology is the first effective salt and chemical-free limescale prevention method, which has been independently tested to 99.6% effectiveness using the German DVGW protocol.

How Long Does The Media Last?
The media in our salt free scale inhibitors needs to be replaced approximately every 3 years for point of entry, or every year for point of use applications. Refill packs are available by model size (eg; 10″ x 19″).

Installation Information
For installations where new copper pipework is required on the feed to the system, the new pipework should be left to passivate for a minimum of 4 weeks. We recommend installing the vessel without the media during this period and inserting the media at a later date when the pipework has had time to passivate. If this is not done then excess copper can foul the media and dramatically reduce its lifespan and effectiveness.

Why Choose Our Salt Free Scale Inhibitors?

  • Prevents limescale formation and clears existing build-up
  • Tested to be 99.6% as effective as a water softener
  • Small footprint with no power or drain required
  • Built in bypass for an easy installation
  • WQA gold seal approved media

Very pleased with the service. There was an issue with the water softener I ordered initially, but then following communications made the replacement process quite pleasant. Happily recommend this company. Thanks to Becky for working with me. Great follow up support 😊😊😊

First time using this company and product and i wasnt dissappointed. Communication was easy and quick resulted in an easy order and now having fitted the filter i can say its a great product easy to install and appears good quality apart from the four mild steel bracket screws stainless would have been better considering the environment these are fitted. All in all, very pleased and would highly recommend .

Excellent local company and genuinely lovely people to deal with. Really helpful and knowledgeable, with great advice about my water softener and the correct salt to use. They even gave me some resin cleaner at no charge, which was a very kind gesture. Fantastic friendly service and I’ll definitely be returning for my salt in future. Highly recommended.

Excellent service. Product proved my softener was not working as it should. I fully serviced it and cleaned with Resin Clean returned to service and it is now working as designed. Very pleased.

If you're thinking about a water softener then i HIGHLY recommend Ultra Soft Water Softeners Ltd. Great softeners and exceptional customer service. The water softener I bought needed some adjustments with the installation setup where I supported throughout. The customer service is honestly next level. I had countless calls with Becky Gillett, the Sales Manager, over a period of months to get to the bottom of it. She was incredibly patient with me, staying on the phone and doing video calls to walk me through the programming instructions step-by-step while I changed the settings and ensured all was installed correctly. All the staff here have been great, but Becky really stuck with me from start to finish to make sure it was sorted and working well. It runs like a dream now. HIGHLY recommend them!

Easy to order, quick delivery, good communication. Resclean worked a treat; one treatment cycle and soft water is back again from our 12 yr old softener!
