Custom Spray Nozzle Solutions – Material Injection Coverage
Application #061070
Industry: Chemical Processing
Application: Material Injection
Product Description: Full Cone, Modified Bete XAAD Air Cap
Situation: A customer approached Bete asking if there was any way to improve the coverage out of an XA-type nozzle. They needed a very full cone spray in order to sanitize a container roughly the size of a ½ gallon (2 liter) milk carton. They had been offered several catalog solutions from competitors, but nothing was working.
Solution: Full cone spray patterns are very difficult to generate with air atomizing nozzles. The droplet-laden air being ejected from an orifice can only expand so much after exiting. After this, the air will simply continue moving forward in a cloud without expanding further. This is why the Bete XAPR is a low angle (10-20°) spray.
The Bete XAAD nozzle addresses this limitation by using six separate holes to create a wider pattern, although the spray is a hollow cone. To create a full cone pattern, BETE’s Application Engineers added three additional holes inside the standard six-hole pattern of an XAAD Air Cap 1602. Doing this created an air cap that performed similarly to the XAAD AC1603, but was much fuller.
