GEA Niro CIP nozzle uses a design where the nozzle head retracts when not in use and is, therefore, ideal for mounting on any plant component.
- Easy to install
- Automatically retracting when not in use
- No compressed air needed.
During CIP operation, the water or another cleaning fluid is pumped to the nozzle under pressure, which forces the nozzle head into the correct position for cleaning the plant. The CIP nozzle head is fitted with a spray ring that rotates according to the feed pressure. Once the feed is stopped, the CIP nozzle head automatically returns to its starting position.
The CIP units can be fitted to both thin and thick gauge equipment, both insulated and non-insulated. The CIP nozzles can be fitted on spray drying chambers, cyclones, fluid beds, tanks, and ducts. The units can also be supplied in different lengths.
A hole is cut at the appropriate position and the unit is tack welded into place. This avoids warping of the unit and component when the CIP nozzle is finish-welded. In addition to the CIP unit, a drainage pipe is fitted to drain away excess fluid and, if the liquid is been recirculated to the nozzle, a liquid filtering procedure is also fitted.
The spray angle of the CIP nozzles range from 70-130º. As the CIP liquids are supplied at only 2 bar (with a maximum total capacity of 4 cubic metres/hour), the units are inherently safe.
