The nozzle CSL and the principle of atomization developed by CALDYN has
been proven as avery economical spraying technology. Liquid and gas are mixed at low velocities
in a mixing chamber and accelerated to the sonic velocity of the two phase mixture (patented
The atomization is achieved by the pressure jump at the outlet of the nozzle when the mixture
is expanded in a gas. The largest stable droplet can exactly be defined!
The angle of atomization of a single CSL nozzle is 15°, therefore the atomization can be
realized in very small channels.
For larger flow cross sections and any injection geometry several nozzles or nozzle clusters
can be used.
