Features

  • HOW IT WORKS: Yarna CWD48 is a Patented alternative water softner for homes that treats water with electric pulses generated within the electronic unit and controlled by a micro-chip! These pulses are transmitted via our Ultra Flat Impulse Bands which breakdown crystals that would otherwise buildup into limescale, which can break appliances.
  • WHO BENEFITS FROM YARNA: Our customers report cleaner pipes and faucets, lower costs for descaling and heating, and better overall water quality using our whole house water softener system alternative. Depending on the current condition of your plumbing, it may take up to three months to observe a significant improvement

  • Easier set up, cheaper, smaller, and more effective than any other industrial Descaler.
Size: CWD 48 - 4" Pipe
My 4th and hopefully final descaler, purchased the Yarna CWD48 for just 100$ more than than the residential model, just from experience Phoenix residents need commercial level descalers that can handle the Phoenix water 900ppm irrigating at 50gpm. Pros: Fastest install ever, thick copper bands wind quick, outdoor waterproof , so small can put anywhere, live oscilloscope display, (I don't have to use my own oscilloscope to check status of my descaler any more. Treats up to 4" pipe, 1.2 miles, that's industrial grade , it will have no problem handling 900ppm at 50gpg I have been using electronic descalers for the past 10yrs to reduce amount of mineral build up in the kitchen and bathrooms, to make cleaning easy, and less frequent, no ring around the toilet bowl, any calcium build up on plastic shower heads wipes of with a sponge once a month or every other month. Added bonuses: my lawn irrigation drip system and sprinklers have very little build up and require little to no maintenance cleaning/changing heads, Haven't changed a drip or sprinkler head since I moved in 4yrs ago, which is rare in phoenix for drip systems have about 20 drip heads running all year and 20 sprinklers with K Rain (screw on) rotary heads. My misting system requires very little maintenance with a occasional cleaning of a few heads during the year, for a system of 40 misters with 0.3mm orifice this is unheard of in phoenix. This is my 4th electronic descaler : At first I didn't understand the importance for testing gpg/ppm which in Phoenix uses well water in the summer goes as high as 900ppm /52gpg drops to 500-600 in winter when it uses surface water. So Phoenix area residents require a descaler that will go up to at least 60gpg or 1000ppm, typical residential models are not designed for use in phoenix especially when you want to use for irrigation system which is up to 50gpm at 850ppm, you need to buy a industrial/commercial descaler or note the gpm and gpg rating if buying a residental My 1st descaler DIY PCB descaler, square wave generator - noticed enough difference that convinced me descalers do work Cons: low power 12-18Volts ,50 windings, weak inductance, constant frequency pros :great starter model for 20$ Scale Blaster residential model SB-70 - noticed a bigger difference. Pros: good product for 75$ used, would work well in northern cities Cons: had to mount indoors and runs signal wire out through wall required a lot of windings, only up to 19gpg, Industrial/commercial (SB Max older version which treats up to 100gpg) - worked excellent, great product. very expensive retail 999$ found used for 399$ ,very large had to install inside the house all though it is rated for outdoor use I couldn't find the information on heat tolerance levels and customer service via phone didn't or wouldn't give that information cause the model was discontinued, long summers of 120F create internal temps of southern exposed metal machine towards 160F I assumed that would shorten the life significantly. so I ran the signal wire through the wall and had to wrap the wire 210 windings around 3/4inch incoming copper, which was really difficult, would still be using it but after 4yrs of use the wave generator became very loud, since it was inside the house it was disrupting sleep at night, so I gave it away. (Newer model of SB-Max only treats up to 40gpg can't use in Phoenix) ... show more

  • Innovative solution to tough problem, GREAT customer service!
Size: CWD 48 - 4" Pipe
We live in a small western mountain town with very hard water, and the high terrace where the house sits has quite limited land around it. Installing an old-fashioned salt-based system would have taken up valuable space. In addition, it would have been notably more expensive than the salt systems I had installed before on level ground on the east coast because of the labor and equipment required to hoist everything up to this level (not to mention the ongoing efforts to haul bags of salt up). When I was considering the Yarna system as an alternative, I mentioned it to a friend in Alaska who told me it was the same technology (scaled down, of course) which the big oil companies use on the pipeline up there. I was still a bit skeptical, but we purchased the product, and our handyman had it installed and operating within an hour...very simple, and it takes up almost no space. The next morning, my partner was all smiles when she got out of the shower because she got far more suds and said she finally felt really clean. She also mentioned the lack of "sliminess" she had always felt with salt-softened water. After a few weeks, I noticed we were no longer getting the mineral rings on the toilets which had previously required constant cleaning. In short, we were both quite happy. My old salt systems could not have done better, and in fact, we like this better. The one thing to note: if you leave water sitting for weeks (as we did on vacation a month or so ago), the minerals will start to crystalize again since this system does not remove them, just ionizes them for a period of time so they don't have a chance to do so (at least that's the way I understand it). The true test of a product and the company behind it, though, is what happens if something goes wrong. Every manufacturer, no matter how top-notch their quality control, winds up with a few "lemons" from time to time. Our unit worked fine for about six months, then quit (or, at least, the LED indicator stopped working). I have become so cynical about warranties that, at first, I thought of just throwing it in the trash and trying something else. Instead, I contacted the company, and a wonderful rep named Girlie responded immediately, told me the warranty was certainly in effect, and advised me on the simple process. Within a very short period, we had a replacement unit which is again providing excellent water. I've been on this earth for many years and have had many similar issues, but I can't think of any resolutions which have been more pleasant. Thank you, Girlie and Yarna! ... show more

  • Edited: not recommended
Size: CWD 48 - 4" Pipe
Well I'm giving this a shot. We have a well and pressure tank. Our water maxed out the hardness strips when I tested I five minutes before install. Install is super easy but with limited space I really struggled to get it wrapped around the pipe a minimum of nine times like it said. I saw where someone else said to let it overlap rather than leave a gap so I tried to do that. We live where it's extremely cold and have wires along the pipes as well to keep them from freezing in the winter so I'm not sure if that will hinder it or not. I contacted support through email because everyone said they are amazing, I wasn't super impressed and I'm really frustrated because I sent emails with videos and pictures asking how to do it better, if this was acceptable, if this would work. I just got canned responses back saying to give it time. So no help with install at all, the only helpful response was that it has to be before the pressure tank or it won't make much difference. If you have a lot of exposed pipe I'm sure this would be easy but we have a small area and this has me unsure about whether it will work. The lack of tech support makes me less likely to recommend this as the reason I went with this product was because of the rave reviews about tech support. Edit: It's been a few months. The hardness strips are still maxed out but now there is a white powdery substance on EVERYTHING our water touches. I'm not sure what's going on but I'm not a fan and there has been no customer service assistance. Our water is still itchy and our skin is still rough feeling and our shower heads are getting clogged with the white powder. For this amount of money I definitely recommend something else. This won't help your hard water. ... show more
