Hi, I'm Les Rapchak
CEO for Nex Flow Air Products Corp.
We're a worldwide manufacturer of specialized compressed air technology
for moving, cooling, drying and cooling
With me today, I have our vortex tube technology
A vortex tube is a device that takes compressed air and literally splits the stream up into hot and a cold stream of air
one inside gets hot, this side gets cold. Just to show you how it works
If you can see this thermometer here the environment that I'm right now in is actually at 37°C
it's very hot. The compressed air we're using is very hot
so what I'm going to do now is turn on the compressed air to the vortex tube
and we're going to measure the temperature drop that occurs on the inside
You look at the thermometer as you see it working on the vortex tube now if you zoom into the thermometer
We'll see the temperature dropping
So as you can see even with an environment at 37°C with warm compressed air
we were able to achieve a cold temperature of less than -4°C coming out of the vortex tube
You actually control the temperature coming out and the flow rate coming out at the cold end
with this adjustable hot end screw
which you use and adjust with the screwdriver
If you don't want to use a screwdriver, we have another version
That's hand adjustable
That can be used on both this size vortex tube and one size smaller
There are 3 different sizes of vortex tubes
the small one
The medium one which I just demonstrated
and the large size
Vortex tubes are capable of producing a cooling rate of up to 10,800 BTU/Hour of cooling with the large size
To control the flow of air in the vortex tube and the consumption of the air in the vortex tube
We have different generators for the different sizes
We have two types of generators,
a generator that gives you maximum cold temperature and a generator gives you maximum cooling effect
Contact Nex Flow for their technical expertise and they can assist you
What's very popular is our packaged version of vortex tubes
We have the adjustable spot cooler. Which is here
you have a knob which can adjust the cold temperature
We have the small mini cooler ideal for very small spot cooling applications
We have the very popular tool cooler
Which is used for dry machining applications such as in cutting glass and cutting plastic
and finally we have the Nex Flow patented mist cooler
which actually tool coolant or any sort of material area where you need maybe some lubrication
in a machining application ideal for mist cooling applications
you can reduce your lubricant or your coolant used in mist cooling up to 20%
by cooling it with the mist cooler and by cooling the compressed air
One of our most popular package versions of the vortex tubes is our panel cooler.
We have two sizes for different applications
of all the manufacturers of this technology, we are the only one that have the widest range of approvals for use
We have them approved for NEMA 12 applications or IP 52
We have it approved for outside use which is IP 14 or NEMA 3R
And we have versions which are patented with a patented system by Nex Flow
for NEMA 4, 4X or  IP 66 applications
Unlike our competitors who make their generators out of plastic
We produce ours only out of metal
We machined them out of brass with consistent quality for consistent operation throughout
Our vortex tube bodies and most of the accessories are manufactured out of stainless steel
