The alternative to (cooling) lubricants or in combination: Ensures cooling, reduces wear and welds -absolutely without residue.
The cooling nozzles operate on the principle of the vortex tube and serve to generate a rapid cooling of the tool and/or workpiece.
The incoming compressed air is swirled in the generator chamber and is divided into two air streams.
The outer, smaller part of the air stream is compressed, due to the geometry, along the vortex tube, accelerated (speed of sound) and escapes as hot air through a needle valve. The inner air spiral has a slower movement, gives off heat to the faster air and is supplied as cold air via the cold pipe to the tool or workpiece
The cooling nozzles of the KD series are available in different versions and differ in air volume and cooling capacity.
They consist of the aluminum vortex tube, the built-in generator, the mounted external cold tube, a threaded port and a hot air valve control valve.
Further optional equipment such as connections, control, filter regulator, brackets and air nozzles are available on request.
