Aqua Vortex Tube – Make Hot and Cold Water using Free Water Pressure

The vortex tube, also known as the Ranque-Hilsch vortex tube, is a mechanical device that separates a compressed gas into hot and cold streams. It has no moving parts.

Vortex Tube

This is a curious device that uses compressed air as the energy source and makes cold air (coming out the left side) and hot air (coming out the right side).

See the Wikipedia article at:

Even though one can make instant hot or cold air with this device, it is not considered efficient because no-one has come up with an efficient device to make compressed air.  I have a very efficient way to make compressed air very inexpensively, but that is the subject of another page.

I am an American and we have water pressure in most locals within the United States that is standardized at 30 pounds per square inch (PSI).  I am not sure about the rest of the world, but most places probably have something similar.  My point here is that when most of us turn on our water faucets or outside garden hose, we get pressurized water; we are already paying for it.

As we have this “free” energy, I turned my inventiveness on how to make modifications to the above “vortex tube” so that it could be used to make instant hot and cold water; no electrical “heating” elements or refrigeration needed.

My new Aqua Vortex Tube uses the same approach, but is significantly different in that it uses water (or other liquids) and can be designed for hot water only, cold water only or both hot and cold water.  With this new device, depending on the pressure behind the water (we are using 30 PSI), “room” temperature water at 72 degree Fahrenheit can be instantly made into 180 degree very hot water.  This very hot water can be moderated by adding cold water into the line before use, if desired.  Equally, 72 degree water can be made into very cold water that forms ice cubes instantly.

This Aqua Vortex Tube is so efficient at making hot and cold water that it will require a minor change in plumbing to accommodate hot water tubing around the cold exit pipe and cold water tubing around the hot exit pipe but that could be incorporated into the same device commercially.

This device can be used in the home, in restaurants, offices and industrial/manufacturing facilities.  It can also be used on boats, ships, yachts, trains and aircraft of all varieties that use or dispense water or other “drinks.”

Just imagine, no water heater or refrigerator or freezer is needed, just already free, water pressure.  In the Tropics or summer months, this device will cut significant electricity costs when making ice cubes.

This device is also ideal for oil and natural gas pipelines that must be heated in cold climates for efficient transit.

    I am very interested in your hot and cold water device. How many gallons per minute can it produce with 30 psi? I have a need for thousands of these units immediately so I would greatly appreciate a rapid response. I have access to mass manufacturing to help with production if necessary.

    • Merln says:

      This, too, can be released for manufacturing in short order. These can be made from strong, food grade plastic, but it must be able to withstand 45 PSI minimum and up to boiling water temperatures. Perhaps stainless steel may be better. Like the Cone2Cone valve device and the Improved Ball Bearings, the Aqua Vortex Tube can be manufactured using 3D Printing, probably (I believe it can be done).
      Using 30 PSI (Pounds per Square Inch), whatever your flow rate is now, the Vortex Tube will accommodate that flow in either hot water, cold water or a mix of each. Call it 2 gallons/minute, but very similar to filling a bucket with your hose.
      The Vortex devices can be stand alone and inserted into the hot and cold water lines, or it can be a more complex combo unit; either way local laws may require the units to be installed by a plumber.
      Having said that, remember, this does not require any electricity to make hot or cold water (it uses water pressure) and a DYIer could install these after turning the water flow off.
      The Aqua Vortex Tube units are either tuned for hot or cold water and a combo unit would use one of each tuned units; Hot ones could be red and cold ones, blue.
      Email me on the proposed unit manufacturing cost, licensing fee and unit cost. Review the size and complexity of a hot air Vortex Tube; this will be similar, but will fit under the kitchen sink or other cabinets or, alternatively, down by the water intake area in the basement or utility closet.
      One last point, more pressure makes the water colder or hotter; you can make boiling or steaming hot water or make ice cubes much more quickly (water coming out at 33 degrees F). These devices will revolutionize hot and cold beverage service as well. All you need is water pressure that you are getting free from the water utility you are now using. Yes, it can be used to revolutionize refrigeration, without gas compression/compressors, as well.
      I have a cistern with a bladder pump that is set for 45 PSI all of the time; this technology is readily available for everyone.

    What would the “icecubes” look like? Snow/Hail/bigballs?
    Can you contact me for this device and how to get it working making “snow”.?

    • Merln says:

      Yes, the pressurized, nearly freezing water can be “sprayed” out as a fine mist and can be used to make various kinds of snow. Depending on how cold the atmosphere is, this device could be used to create “powder,” not just snow.
      The trick would be having a heated tank of water as in a vehicle with a gasoline or diesel engine (for the heat). Up slope, the heated water tank(s) could be built in to buildings or underground piping; six (6) feet down, the earth temperature is 50 degree Fahrenheit all year long. This technology could be used to open the slopes sooner and keep them open longer.

    Doesn’t volume need to compress and expand to get cold? I just retired and have time to play around with things that fascinated me fro years ago. I would love to look into this only for my curiosity. Thanx-ray

    • Merln says:

      Hi Ray, look up how the original vortex tube operates; it produces heat or hot air. It is using compressed air and has some expansion in the process. I took that baseline model and modified to work with another fluid – water, that is also under pressure. You are right, there is a different approach for how cold water is made vs hot. So, yes, there are two versions; hot and cold. This variation in how to produce cold fluid is also applicable to the original vortex tube (1923) for making cold air.

      So. Thank you for making me think it through. This is another revolution in air conditioning and freezing air; I was just focused on making hot and cold water. Think other fluids like coffee/tea makers that brew first, but don’t keep heating. This fluid technology would allow the coffee to be served hot (or cold) without having to be microwaved (or ice cubes).

      On the gas side, I suppose that the new vortex tube approach could be used to liquefy oxygen and nitrogen much more economically. A double-walled scuba tank could also hold a lot more liquefied air; be smaller or allow longer dives. Of course, this applies to space walks as well. This would tie into my alloy that takes the carbon out of carbon dioxide/monoxide and allows the oxygen to be re-breathed efficiently.

      Sounds awesome, I just learned about vortex tubes for heating gas inside a pipeline. I was curious to see if these could be used for water and I came upon this site, my question is how do I get one? I have several uses for something like this if I knew how to find it, thanks

      • Merln says:

        Hi Dave, Several people have asked me for versions of the Aqua Vortex Tube. All of these technologies have had to wait until we got fully into Aquarian Energies. We are there now and I expect that the Fluid Dynamics Vortex Tube (to include hot and cold air, hot and cold water and hot and cold other liquids/gases)will be out into the world by this time next year. Just think, make natural gas into liquid natural gas (LNG) without expensive, additional compression and without miles of pipes.

  4. Dave czar says:

    Ok,thank you, will they be available through this site? I would love to use these for my water heater, and possibly a pool or hot-tub? I will keep my eyes open for when they are available. Thanks for the reply!

  5. L Hope says:

    Any update on the Aqua Vortex Tube?

    • Merln says:

      Yes. it is on the list to be brought out into the world as soon as the world is ready for it. My problem is that I do not have, nor believe in Patents. So, I must wait until I have success in one technology before I can fund others. I, like Tesla before me, am an idea man. Tesla had to hook up with Westinghouse and later, Morgan, to get funding for his technologies and he brought many technologies into our world.

      If I can bring any of these technologies into the world, I will have all of the funding needed to bring the others along. Somehow, I have been given this rare talent to pull technologies from a creative source. At some point, providence will allow me to do something with them.

      If you have any ideas, share them? Either this way or via my email.
