Jet coolerseries MJC |
|
Jet out cooler air maximum 60°C(max. temp. drop) lower than
the inlet air only by supplying compressed air. Uses the theory of vortex, no moving parts are used in the construction, hence long life sustainability. Does not require coolant or an electrical source, utilises the high speed flow of compressed air for generating cool air from hot air. Ideal for applications where rapid cooling is required, (ie) Spot Welding. Can produce consistent supply of cool air even when the supply in is 40 Degrees C. By changing air consumption you can simply change the cooling temperature.

Cool air temperature adjustment
Use the adjustment screw at the rear of the main unit for adjustment of temperature. Counterclock-wise turning (loosening) of the adjustment screw will lower the temperature, decreasing the cold air temperature, Clockwise turning (tightening) of the adjustment screw will bring opposite results. |
Notes on operation
- Do not use this product for other purposes than its original usage or the range of its specifications.
- Do not use this product with other gases than air.
- Do not remove any part to use it for any other equipment, or do not use any other parts than the specified items.
- Use the product in the range of working pressure being 0.3~0.7 MPa.
- Note that hot air is discharged from the hot air exhaustion port during the product use. Take care not to get burnt because the section protected with mesh may become as hot as 70°C at the maximum when the inlet air temperature is 20°C depending on the use conditions.
- Abmission of dust or oil may reduce the cooling ability. Supply only clean air.
- Moisture contained in the compressed air to be supplied will cause freezing in the cold air nozzle section.l If the nozzle is frozen, ice particles will take place in the cooling air. For prevention of such trouble, be sure to supply dry air that have been dehydrated by an air drier or similar other devices.
- Install an air filter (40um or finer) and an oil mist separator in order to prevent the cooling ability from lowering due to dust, oil or other substances.
- Use large inner diameter tubes and fittings as large as possible for input ports. Small inner dimeter tubes and fitting make insufficient air supply and cause the cooling performance decrease. Please check the capacity page of catalog for recommended air sonsumption value.
- While piping the cool air port, the fittings and tube must be insulation materials.Or the surface of tube will occur condensed water or ice and cause the output port of tube reduce the cooling performance
Temperature drop of cool air
Graph description (example - MJC-150K)
1. One time of rotating the adjust
screw from tightening condition. 2. Temperature drop is around 48°C under the condition of air pressure = 0.5 MPa and cold air flow rate = 58 L/min(ANR) |
Cooling capacity
* The heat quantity which is able to be absorbed (cooling).
