In this video I show you how to build your own compressor aftercooler and cooling coil using copper pipe. The aftercooler will greatly reduce the moisture in your tank and air system. The benefits of reducing moisture in your compressed air are:
The aftercooler works far better than the cooling coil. If I had to choose one to use I would use the aftercooler. The tank will last much longer if your compressor has an aftercooler. A lot of higher end air compressors come with them as a factory option. They can be added yourself for far cheaper. Both the cooling coil and the aftercooler work on the same principle. When air is cooled any water vapor is condenced back into water. A properly working dryer system will trap this water an keep it out of the air system.

I made a VERY cheap "refrigerated" water trap many years (when I was broke) ago when I had a painting shop. I bought a 25' coiled yellow hose, fittings and a water separator like you have. I drilled two holes in a plastic 5 gallon bucket side by side at the top. pushed the coiled hose ends through them from the inside, attached the rest of the stuff. Then I filled the bucket with ice and water and weighted the hose down. Worked like a charm.

2 things- The superheated compressed air won’t drop its moisture until it returns close to room temperature. If you put your coolers on the other side of the shop away from the compressor heat, it helps. The “fan” cast into the compressor pulley is a joke. Get a $10 box fan or 2, and mount them so they blow over the electric motor and compressor. That’s made the biggest difference on my set up.

Only thing is, you want to cool before the tank to keep the water out of your tank. If the cooler is across the shop you are running pipe both ways. Agree on the small electric fan - made a huge difference for me too but I have it blowing on the aftercooler mounted right on the compressor.

@tyking1533 5 жыл бұрын

First, Thanks @Repair Geek for the great idea, as well as sharing it. I followed this exact design method and can attest that it works very well. Once the system was installed I measured the the tank inlet temps, and comparing them to the outlet temp at the pump I've seen as much as a 175 degree difference between the two on a 70 degree day. Plus, even in the dry air of the western state where I live, I typically get a couple ounces of water in the moisture trap during a single tank fill on a 60 gallon compressor. This is water that's not going into my tank or into the lines downstream. This design works. I used all soft 1/2 copper, picked up a tubing bender which helped routing the copper on the compressor, and bought a flare tool for the fittings to the transmission cooler. Putting it together probably took me the better part of a day all totaled with a couple trips to the hardware store, but it was totally worth it. Almost looks like a factory accessory, and the secondary water/oil trap before my primary regulator has been nearly dry since. A couple weeks ago I was running an HVLP gun for almost two hours painting a fence. I lost track of how many times the compressor refilled. The water/oil trap on the compressor had pumped out a solid cup of liquid (auto-drain). The trap before my regulator stage had a couple drops of water inside. I hit the blow off valve on the tank and got what was probably an ounce of water.

(it's a 16 pass cooler w 12" per pass) PLUS it has fins. Air over the fins makes a huge difference. Now there is nearly zero water collection in my tank, lines or wall mounted separator - it all ends up in the separator before the tank. This mod is highly recommended. And it's much cheaper, simpler and more compact than the pipes on the wall.

I like a good research adventure! BTW, I think you’ll find that the mfr. anticipated the air tank acting as a condenser and that after won’t hurt it if it’s drained daily through the petcock. Also, the most efficient use of your aftertank 50’ of rigid cooling line is to run it at a slight downward incline across your walls with as few 90 degree elbows as you can, with several drops along the way to collect and remove the water. This is more efficient at water removal than your up and down course where some air, trying to loose water, is forced to rise against a waterfall of 100% humidity that won’t accept it. Such a system is remarkably capable at removing water. But your experiments made a very Interesting and thought provoking video from which I gleaned several great ideas and enjoyed very much. Thanks.

I used this exact transmission cooler on my set up. I originally used 5/8 copper tubing to connect from the pump to the cooler inlet, the cooler outlet to the separators and again from the separators to the tank. I was concerned about the vibrations being transferred to the cooler so replaced the line to the cooler with a stainless PTFE lined hose and the other connections with a 1/2 whip hoses. Galvanic corrosion played a huge roll in component choices here. I also added a 12v fan to the cooler to supplement airflow and ensure proper cooling during continuous duty cycles of the compressor during blasting. It is wired to run when the compressor activates. I was not aware the regular 45 degree flare would work with the AN fittings on the cooler. As of now my weakest link in this is the anodized aluminum AN to npt fittings connected to the cooler. I figured these would be easy enough to replace if they corroded to the point of failure. Stainless AN fittings are upwards of $75 each!

@bobbg9041 5 жыл бұрын

die electric union or plastic fitting between dissimilar metals. Good eye! as copper and cast iron don't mix well together. I would not waste my money on steel pipe anyway. Just use high pressure rubber hose and no problems with galvanic corrosion. your weak link will be that hose as rubber dosn't last forever but it will save the compressor tank and help cut down noise from vibrations.

@VB-bk1lh 4 жыл бұрын

I would also pay close attention to the tubing size of the trans cooler vs. the compressor outlet size, if the tubing in the cooler is smaller than the original compressor outlet tube size you may decrease efficiency and create more heat at the compressor. Also, if all tubing is the same size, I believe there may also be a greater expansion effect at the water separator which I think would cause even more moisture drop out. With the amount of water your getting, you may also want to consider a different type of air cleaner and longer drop tubes on the copper tube cooler on the wall. I could see it accumulating quite a bit of water if you were able to catch 2oz in that short amount of time. an all day run on a humid day may leave the drops overfilled on that wall cooler. On my system, I used a through the wall heat exchanger which I adapted from a commercial application, its basically a huge high pressure radiator with 1" tubes. I made a 2" diameter, 30" long drop below it to catch and hold moisture with an manual drain. Every drop line in my entire air system also has a drop and a clean out valve beneath every coupler. Water get caught at all points but the most is caught at the cooler. My cylinder head temps on my compressor are no where near what your seeing but I'm running a dual pump Quincy with two 5hp three phase motors. It doesn't turn near the RPM yours does. The hottest I've seen on a 98 degree day has been around 171 degrees F. Both pumps are pressure lubricated and I'm running 240 psi into 210 gallon air tank with an additional reserve storage tank on the far end of the system of the same size with its own water drain system and separator. At one time the system was running a full machine shop but these days its only for my personal use, mostly running a few machines and some painting. I have four dedicated 'painting lines' each with a charcoal canister and desiccant based water separator and mechanical regulator.

@SR-gt350 4 жыл бұрын

On the copper exchanger, run the 6 tubes in parallel by having a top/btm header then the velocity and pressure drop will be less to allow for more moisture to drop out. It will allow you to have one auto drain separator on the bottom header to drain moisture. Excellent job!

Imagine six tubes, all running vertically and all tied together by tees on the top and on the bottom. Inlet of air gets separated six ways on the bottom and the outlet receive that air at the top. The idea is to slow down the flow rate of air by splitting the total flow into six separate vertical pipes. Much like a header on an engine but with reverse flow rate. Then just tie the auto separator down at the bottom, eliminating the need for expensive ball valves. Also this can be done in large diameter, large schedule PVC or PEX for reduced cost. Makes sense now, my friend?

Everyone does what they can and with a budget but I simply cannot believe how many air dryer's I've seen done on you tube and NONE (almost none found 2 that did separate the compressor hot air to a dryer before returning to the tank) for nearly perfectly dry air, which saves on consumables in my Plasma cutter. Painting requires an inline desiccant filter and regulator.

@@Jeff_Seely What do T's at the top of the runs do for you specifically ????? I've seen a number of designs and most of them use the T at the bottom with 90's on the top and usually incorrectly install the T. The T needs to be on the 2nd, 4th, and 6th run of copper lines to form a turbulent vortex which helps eliminate the water to your drain valves. Mine are 6" drain catcher's. I've seen anywhere from 2-8" and anything less than 4" is too small. I sent all this back to my TANK and then installed a 5 filter / desiccant system to get pure air for my plasma table. Clearly this guy installed the T's on the wrong pipe and oriented incorrectly. Flip them to the 2,4 and 6th pipes with the drain under them and you have a better mouse trap.

You still have a small amount of condensation that forms inside the tank. I've had about a tablespoon sized amount come out of the tank drain. Just like a fuel tank of a car that's in storage, condensation will form inside a sealed container if it's left for a long period of time. You still may want to look at an automatic tank drain just in case.

One large mistake, that I think you distribution system video touched on, was to not run your long distribution system low, but run it high; run the primary pipes as large as practical (150% of necessary flow design at a minimum), with a slight down hill grade in the direction of flow. When you make a 90 degree turn, left, right or down, plan a drain leg and valve- Each drop point should come out of the top of your primary tube about 1-2 inches; you will have trapped most of the moisture remaining in the air in the primary- local drier/filters will get most of the rest. This method avoids the expense and complication of refrigerated driers, has no real moving parts (just the drain valves- which can be as small as possible"/economical) and uses no more electricity. I've built small shop systems (5hp/20gal) to large mfg (125hp/ 3x 80 gal tanks) and been very happy with my customers reactions. Including drain legs at most drops helps both actually and assures the port user they have safer cleaner air.FR

If you need the pressure dropped for the end use you could always utilize that decompression to take extra heat with it by adding an enclosed evaporator between the first cooler and the trap and dropping the bulk of the pressure through an expansion valve there.

It's all about lowering the dew point of the "saturated" water vapor in the line. Your intercooler is a good idea, and will lower the temperature of your tank, therefore the water content of your air. I painted my car by running high-pressure air from the compressor tank thru a 50-ft coil of 3/8" copper tubing submerged in a tray of ice/water, then thru a filter/separator and finally the regulator. This setup would be impractical for regular use, but in my case it worked very well.

I now can run my media blaster for hours, paint run tools or whatever and never have any water at the final regulator - ZERO visible moisture. Big side benefit is your compressor runs cooler. After cooler gave me a big temperature drop from the cylinder head outlet to the tank inlet. I tried downstream copper cooling coils but they were waste of money and time for me. Biggest bang for the buck is an after cooler setup. Need to fight the moisture as far upstream as possible. Trying to control the moisture downstream with only regulator filters and desiccant is a losing battle. If I had only figured this out years ago...

I'm sure glad to see the struggle of others before I start my journey. I have a opportunity to use an amalgam of these ideas such as substituting the after cooler for a manifold that can be ran into an existing heat sink (ground water exchanger) that is right next to my compressor. I have sought to find ways to control and utilize as many sources of temp difference required as I can in my place. Well water for Dehumidifiering in the shop and other semi enclosed areas is another prototype I have been installing infrastructure to use over the last decade's of evolution. IDEALLY I would use only one cooling device to run my environmental needs and a walk in pantry/refrigerator/deep freeze. All have been taken into account for every move while building my engineered homestead. Patience has been rewarding.

The reason the aftercooler after pump is efficient in removing moisture is because the tube is preassurizing more than in tank or after tank. For optimal removal of moisture preassure is important, the more preassure and the greater the temprature difference the more efficient removal. You can also use running cold water on fins of cooler that would remove even more water. You can also use a vortex tube to cool the air and then feed into water separator but vortex tube will consume 6cfm constant.

A few thoughts, I'd be slightly concerned about the copper cooling manifold, I was always told that airlines should be braised and not soldered. And the fittings you used are the pre-soldered or clamp style (??) I would have went with the regular style so I could pump more solder into them. Maybe on editing, mute the compressor noise and add background music! Is that an hour meter you put on your compressor? I'd love to know if that is standard equipment or an add-on, I love it. Again great job.

The aftercooler maybe dropping your discharge air to a 15 degree delta T but what is doing the job is your coalescing filter. DO NOT use a desiccant dryer after a reciprocating compressor they cannot handle the oil vapor and will clog the media. You are also just reducing the heat load, but the moisture is still entrained into the system. The only way you can "remove" moisture is by reaching a minimum of a 38 degree dew point.

@darkshadowsx5949 4 жыл бұрын

i dont know your setup but you can make your cooling coil colder by adding a respectable restriction on the input and a expansion chamber on the other side. the expansion of the gas after the restriction will cool the air down more. its also a part of how AC works. they have expansion chambers to increase efficiency.

@bobb7494 4 жыл бұрын

@oldowl4290 Жыл бұрын

I would wager that if you used the copper system first as the pre-cooler / condenser and the small black condenser as the post tank unit you would get better results and may not need the small condenser grill post tank at all. I say this because the copper, being much larger in diameter, as well likely longer in linear feet too, has more surface area available to help cool the air. I've seen a few other people using the copper set-up only along with a water separator, and that was in fact all that was needed. I've been weighing the costs / benefits of either and while the copper set-up will actually cost about 33% more overall with the fittings and hoses, I simply think it's a better way to go, especially for larger compressors like this. I've also seen several reports of guys busting seals on these little Derale oil cooler units that have become popular and my guess is that over time the water vapor corrodes the aluminum enough to pop a seal because don't forget, they're actually made for oil cooling, not air. If you were to switch it up however, I'd want to sweat the copper joints. Id be weary of compression fittings with rubber seals that could become damaged over time from the hot air, especially at the inlet connection where the air will be at least 200F.

It's a 1/2 brass flare nut. It threads right on to the AN fittings. Supposedly AN fittings are a 37 degree flare and the brass fittings are 45 degree. On paper it shouldn't work, I realize that. So far I haven't had any leaks connecting the two together. Flare the copper tube and use the bass flare nut to hold the tube to the cooler. I didn't spend a lot of time on the fittings because the odds on someone having the exact same compressor as mine are slim at best. Thanks for supporting the channel by using the links.

Unless you have a high temp refrigerated air dryer... which is really just an oversized refrigerated dryer. Also recommend having an electronic drain on the bottom of the tank.

@douglasthompson2740 4 жыл бұрын

Did you notice any reduction in flow with the transmission cooler in line? Most I have seen run a fairly small tubing size. I would also wonder just what their working pressure is rated at? Most interesting setup, something I would consider for my own compressor if the above two questions were satisfied. I know my setup is highly inefficient as I get no water at my filter at all after years of operation and I monthly drain the bottom of the tank and usually get only three or four ounces of water. This is with a fair amount of use certainly not extreme and in a very humid climate. Thanks for the informative video. Doug

@RepairGeek 4 жыл бұрын

The short answer is no it will not restrict air flow as long as the filter is not pugged. Here is why: A straight 1/2" I.D. pipe will flow over 50 CFM @ 100psi. The water separator is rated at 65CFM. The cooler admittedly does not have a flow rating but, even if it's half of a regular 1/2" I.D. pipe that's still over 25CFM. The compressor will only put out around 15CFM @ 100psi. By that logic, my setup has at least another 10 CFM of capacity before the compressor becomes restricted. Also, shown in the video my temperature readings did not drastically increase on the compressor head which would indicate a restriction.

The best dewpoint you can achieve with this is going to be ambient temperature. The majority of the water will be captured by the aftercooler separator, but not much more after that. Every 20 degree drop is a new dewpoint and every 20 degree rise the air will hold twice a much water vapor.

I have a question for you, would there be a benefit of having longer tubes at the bottom going to the 4 drain valves so that more moisture could drain to the bottom? Also, could this same system be build out of the plastic air compressor pipes or PEX that is often seen in commercial shops or large garages? The question is, are the pipes that make up this "air dryer system", required to be copper or brass? Both of those are far more expensive that PEX tubing. What is you opinion? Thank you.

@RepairGeek 3 жыл бұрын

Since I installed the aftercooler on the compressor the copper piping on the wall doesn't collect any moisture. If I had to do it over again there is absolutely no way I would waste my time or money building one. You use copper because copper rejects heat very well. This cools the air and causes the water vapor to cool and condense into liquid where it can be drained. Pex is plastic. Plastic is an insulator. It does not transfer heat therefore will not remove moisture nearly as well as copper.

I was thinking about this. It could be that your first cooler gets more water because it is first in line. The air dryers that use refrigerant above freezing is what I am thinking about buying. My homemade dryer using a freezer - Also I was thinking if you had a chest freezer and put a oh say 20 gallon tank inside of it. Run in and out lines into the top. And as the water freezes it will just fall to the bottom. So you would have to have a small drain at the bottom of the tank, but it could run up and out of the top of the freezer and have a valve or air blower on a 1/4" line after defrosting daily. The advantage to the freezer is the lower air temperature would dry the air to a lower humidity than a dryer that used temperatures above freezing. If you had a freezer that could get say 50 below zero. I am sure there is a table to see what the dew point and water content of the air would be at such low temperatures.
