KSD nozzles are twin-fluid nozzles that inject with a particularly uniform full-cone with a spray angle of up to 30°. The nozzles operate according the principle of external mixing, i.e. gas and liquid are mixed outside the nozzle body.
Compared to internal mixing nozzles, external mixing nozzles have a low tendency to crystallization of the urea. With internal mixing nozzles, blockages occur more frequently, resulting in poor spray performance and requiring extensive cleaning..
In a field test, it was confirmed that the maintenance effort for the KSD0 nozzles during operation with urea solution is significantly lower compared to internal mixing nozzles. With the external mixing KSD nozzles, cleaning is possible during operation without dismantling the nozzles.
