I have always been fascinated with there product. Maybe for the wrong reason. 🙂 My Dad purchased two also and they are stupid expensive. But what I don’t get is if I put a bunch of injectors together on my system everyone would laugh and make fun and say injector are a bad idea. Make them expensive, fancy and oh also GREEN! You have a product! That’s why I enjoy marketing. 🙂
My actual question is not the injector there all the same ss or these fancy kevlar (I think?). It’s the HydraFlex setup. The picture shows I assume 4 functions. If 2 or 3 functions or even 4 are in use at one time…. wouldn’t this reduce the threw put of water thus pulling to much or to little chemical? Which is one of the problems with using injectors in the first place? Thus the 27% chemical savings would either go up or down? In another picture they have 5 functions? Even worse? I might be missing something here…. please let me know. I’m going to build one. LOL 🙂
Also I understand that they use those big well pumps to regulate the water…. which is very important with injectors. Also the bigger units have 2 pumps I assume it’s a fall over but I really don’t care it doesn’t matter. I would just think the pressure can’t be consistent on all functions if pulling water at the same time? I just don’t see it? Unless it’s just good enough and doesn’t matter?
UPDATE: The water intake is 200 psi and the output is anywhere from 60-80 psi like the injectors are rated at or 40 psi like some operator said his has at. Not even sure how you would know that unless there was a gauge on them? Maybe the color denote the psi also?
Did you know…. You can purchase the “quick disconnect” injectors from “Hydraflex™®? ©” (don’t want to infringe on ™®? or © :P) , however you cannot purchase the quick disconnect adapters from them. Hmmmmm? Isn’t that nice? Why not? Oh, that’s right you can, if you purchase one of their “Aqualab™®? ©.” TEN THOUSAND dollar units. Then, they will sell replacement parts for it, which include the quick disconnect fittings. Very frustrating to say the least. IN A STORY NOT RELATED -> If you want to never ever ever worry about check valves again, look into the icheck magnum series which you can buy from Kleen Rite (low ph, high ph, and high pressure) Also, if you are tired of replacing brittle, cracked, sun-drenched, winter haggard poly line, step up and buy the parker (or equiv.) “air brake” line (type B, reinforced). it will last for over 20 years in a carwash, and will outlast stainless steel when running corrosive product thru. I have been running HF thru it for over 3 years now. It is so strong that when a check valve failed, the line did not break, the brass fitting did. All I can say is WOW. If you dig, you can find 3/8 for around or under $350 for 500 feet. Or less by searching ebay for “500 air brake 3/8”. If you account for labor, downtime, and pain in the ass time of frustration with poly that breaks when you look at it wrong, it is well, well worth the extra $. In the long run, it ends up being less. Unless you enjoy replacing lines every or every other year. Some people are into that…They say it is “meditative”.
I just built a system that fixes the problem of pressure you are referring to. The answer is 2 fold. 1.VFD+ Pressure 2.Monitoring Sensor.
Set up where VFD runs at say “40%” putting out 150psi. Then have a sensor that is inline (before manifold) to when a second bay calls for product, and pressure drops, it senses this, and increases the VFD to say 50% to make up for the difference, and retain the 150psi. So on, and so forth depending on how many bays you have. It will take some tweaking, but once it is set, it is set. Also, you only can have a maximum of 5 ports open at once, even if you have 6 different functions, as each bay can only have one selection running at any given time. Email me, and I can give you more info, and / or if you want to buy one rather than build one. It is a very expensive “trial and error” job, as the VFD, pump, and sensor have to do the job right, and give the correct pressures. They will not share any of their tech, as they want us all to buy from them, and not experiment. (and god forbid make their product better) – Oh, and it needs to be 3phase as VFD’s only work on 3Ph. Good luck!
