The PH7 Cart
Starting at Just
$3900.00 +shipping

Our unique design features the only system with a custom built fully welded stainless steel chassis and RO housing. The 1/4" thick stainless housing forms the backbone of our dolly system, which allows us to fully weld our frame directly to our housing. With wheels on both ends, our EZ-load handles make loading and unloading the PH7 a breeze for anyone. Everything we build is quality, durable and built to last. Our products are not mass produced. They are custom built right here in Wisconsin by Myron himself. Another benefit of our products is that they all use universal fittings and filters. "Proprietary filters" and "custom fittings" are all swear words in our opinion. All those terms mean is that you're going to over pay and have to buy specific parts from the seller. This can Increase your odds at having to wait for parts to ship if you ever run into any problems or need replacements. This could mean downtime for your company and costing you even more. All of our systems can be easily worked on and parts found locally at any hardware store or on Amazon, which cuts out the massive up charge from resellers.

 

The PH7 is a 5 stage cart. Sediment, Carbon block, Tech 7, RO, and finally DI.

 

Our two pre-filters consist of first, a 5 micron sediment filter that is designed to filter out any rust, calcium, dirt, or other large sediments. Secondly, the water then runs through a carbon block filter. This second filter is to protect your RO from any chlorine damage that may be found in city water. When buying an RO system ensure that the pre-filters have clear housings. This is ESSENTIAL. Why? Well, without being able to monitor them you really have no idea when to change them. There simply is no hour, or gallon amount that can tell you when to change them. It is simply a matter of what's in the water as to how fast they burn out. This can literally change from job to job. Sometimes they can last weeks or more, sometimes mere hours depending on your area. Other systems risk RO contamination when you can't properly monitor your pre-filters.

 

After our pre filters we have our Wayne booster pump. All RO systems need a pump to run properly. Below is more info on types of pumps and why. Then the water goes through our Tech 7 reaction chamber, a unique invention available only at PH7 Pure Water Systems. It has proven to increase water shed off glass, reducing dry time, as the water acts more hydrophilic and sheets off the glass faster. This also reduces chances at spotting even at higher TDS. Many have found themselves being able to wash at up to 50% higher TDS without spotting. This lets you use your DI filters longer. Also where the Tech 7 is mounted is a standard hose fitting that you can disconnect. We recommend doing so when you change your carbon filter. This allows you to flush that initial carbon out without shooting it into your RO. Most systems do not have this ability. After these two, the water then goes to our Axeon HF5 4040 RO membrane. Below is more info on RO's and why we always choose the HF5. On the back end of the cart is the RO valve. This is where you can start testing how pure the water is before it's sent to your DI. This is important because RO's take time to get the water down. This way you can check it and even use RO only in many areas, saving your DI and making almost free pure water. If the TDS is still not low enough after the RO you can open the DI valve then close the RO and the DI will zero out the water.

 

Educate yourself.

 

RO's:

 

RO filters are not designed for window cleaning, period. We use them in the worst possible way for how an RO filter is actually designed to be used. So we have to acknowledge this and accept that way of thinking. This is a simple fact. RO's are designed to run at high pressures continuously, for efficiency. This is why we ALWAYS recommend using a pump with any RO system. Why is this important, and how does it benefit you? The closer we can run the RO to manufacturer's specifications the better the RO will perform and the longer it will last. Not to mention, making more water and not limiting you to tap pressure. The better the RO performs, the more cost effective it is to run. Running within this sweet spot allows your RO to do even more of the work. Sometimes letting you work without DI, or at the very least sending much lower TDS to your DI. What does that mean? Your DI will last longer, also saving you money. This is a no brainer. So what membrane do we use and recommend? The Axeon HF5 and here's why. Based on all our testing, across all major brands applied to our industry, the HF5 has ALWAYS performed on par or better than literally everything else. Some will claim more flow ect, but this simply isn't the case based on all our actual flow testing. Another benefit, its American made. The question is, what does the "best" cost? Well if you purchase through our Amazon link instead of a reseller it's very affordable. This is why we use only the HF5. Nothing has ever touched it performance or price wise.

 

Pumps:

 

Available pumps that are typically used for RO filters can vary in price, drastically. The three main types are, 12V diaphragm booster pumps, vane pumps, and centrifugal pumps.

 

First we will analyze the diaphragm pump. The main thing is that they are 12V in most cases. This means you are dependent on a battery as a power source. This can be both a positive and a negative, pun intended. The positive side to this is you don't need to hook up to a power outlet, you can use a battery bank or even wire directly to your vehicles battery. The downside to this is having to charge them, and in our experience they seem to have a tendency to wear out quickly. That being said they still have a place. The most practical application for this style of pump is for a static tank setup.

 

Next let's talk about vane pumps. These are commonly used on many pure water systems in our industry. It's a mechanical pump, meaning there are mechanical parts that are rubbing, metal on metal creating a lot of friction inside the pump. They typically run on 110V. The main benefit of a vane pump is their capability of producing high pressure within the RO. This can be very beneficial for making a good amount of pure water. What's the downside? One, they are expensive. Two, although they produce well on the high pressure side, being a mechanical pump means its limited on water flow. Whatever the specification is, that's it. So what does this mean? When it comes to flushing the RO, if your vane pump only pushes 2.5 gallons a minute, that is all you're going to get. (Flushing is vital for maintaining your RO) Hence this means you will have to flush your RO longer after each use, consuming valuable time. Another downside as they start to wear out, metal or metal filings can push through to the RO, as well as the chance for mechanical failure.

 

Lastly let's talk about centrifugal pumps. A centrifugal pump operates through the transfer of rotational energy from one or more driven rotors, called impellers. The action of the impeller increases the water's velocity and pressure and directs it towards the pump outlet. One of the benefits is the fact they are capable of much higher water flow (GPM). We can take advantage of this when flushing the RO membrane. (Flushing is vital for maintaining your RO) Another benefit is that these pumps can still create enough pressure to be within optimal range. The downside you may be limited to how much pressure you can create based on the water source. Lastly the biggest selling point for centrifugal pumps is the price point, which is much cheaper than its counterpart as well excellent longevity. This is why we choose to run a Wayne PLS100 centrifugal pump for our systems. Enhanced flushing, better price point, and they last a very long time! Best bang for your buck.
