※ Based on an inlet temperature of 70℉/21.1℃. The flow (ℓ/min) of the above table is based on 7 bar of the supplied compressed air and the flow rate changes according to the changes in the pressure.
A Vortex Tube is a spot cooling device that will convert an ordinary stream of compressed air (3~9.9Kgf/㎠) into two streams-one hot and one cold. It does not need electricity or any moving parts. Vortex Tube is an appropriate product for industrial or laboratory spot cooling.
Using Vortex Tube, the normal temperature of the primary pressure of 26℃ can be adjusted down to -40℃, and the hot side can be adjusted up to a temperature of 126℃(260F).

(Note) Cold Fraction is the percentage of the total flow which comes out as cold air.
(Note)As shown in the efficiency table above, the drop and increase of temperature are indicated as brief figures, based on the compressed air supplied at 21.1℃, at the inlet side. The figures of drop and increase of temperature change according to the secondary pressure and the temperature of the supply air fed to the line. If the supply pressure is constant in the air line, the air cooler shows errors within±0.5℃(±32.9℉).
Air flow :The SCFM of Vortex Tube is proportional to the inlet pressure by calculating:(PSIG+15)×(Generator Rating) / 115 = Total air consumption

Features
Vortex Tube can separate the plant's compressed air into a hot and cold stream, which is a simple and practical product.
At21.1℃(70℉) for the compressed air in the airline, it can compress the temperature to -40℃(-40℉) at the cold air outlet, and to 110℃ (230℉) at the other side outlet.
The maximum cooling capacity is 3500 BTU/h (881 Kcal).
No moving parts, easy to carry, lightweight, and low cost.
Vortex Tube is a semi-permanent product. If you install and use it in accordance with the regulations, it will not fail.
No electricity and chemicals such as Freon are required. Intrinsically safe. Only clean and dry air is needed in the airline.
Spark does not occur, and is not subject to the interference of RF/EMI.
ON / OFF switch can be controlled immediately in use.
It has a structure that generator exchange(generation) is possible that can respond immediately to changes in the cooling capacity of the Vortex Tube.
No maintenance is required in the case of extended use. Being made of Stainless Steel structure, there is no worry about oxidation or corrosion with it.
Model Selection
Vortex Tubes are classified into small, medium and large models, including SMVT10008M~10035M, and all products are made of stainless steel materials. For themedium and large products except small ones, the prices of the products are the same and the size of each product is also the same. However, the cooling capacity of each model is determined by the generator in the Vortex Tube.
By replacing the generator with one suitable for the capacity of the Vortex Tube, operations can be performed by the appropriate cooling capacity according to the change in the effective cross-sectional area in the inside.
As the temperature of the compressed air in the airline supplied to the Vortex Tube is increased, the temperature discharged to the condenser is decreased. In order to generate maximum efficiency, it is recommend that the secondary pressure supplied to the air line (gauge pressure) should be within 5~7kgf/㎠ (5~7bar).
The maximum operating range should be within Max. 17kgf/㎠ and the minimum operating range should be more than at least Min.1.4kgf/㎠. However, if exceeding thecooling capacity of the Vortex Tube for the equipment to be used, it may lead to the loss of compressed air. So, please select the best model for the equipment to be used.
