The performance range of the SCHLICK model series 822-854 begins at the upper limits of model series 940 and 970. Two-substance units are used throughout this range, where a large reaction or exchange surface is needed by large air flow rates.
External-mix two-substance nozzles allow independent control of the flow rate and fineness of the atomization. The flow rate for all models is controlled through the current liquid pressure difference. In the model with a regulating needle (design 1) the flow rate can also be regulated in accordance with the needle setting. There are two possible designs of nozzle system.
Design 0 with central liquid feed
The nozzle design without pre-atomisation is especially well suited to the atomisation of highly viscous media. Depending on the ability to regulate, the contamination risk and the viscosity, a full-cone swirl chamber or even a three-slotted swirl chamber can be fitted for atomisation. The three-slotted swirl chamber provides better pre-atomisation but is more susceptible to blockages.
Design 1 with a liquid regulation needle
With design 1 the liquid flow can also be set using the liquid-regulating needle.
