To prevent foam from obstructing chemicals, water or food production processes, it is necessary to use sprays that can uniformly knock down foam over a wide area. Full cone spray designs are typically recommended for this purpose, despite sacrificing some impact. However, most foam does not require high impact spraying to suppress it, so impact reduction is not usually a concern.
For applications where foam can form over a large area, nozzles with a wide spray point are necessary. Synergy offers several wide spray point nozzles for this purpose, although increasing spray point reduces impact even further. While this is not usually a problem for foam suppression, it is something to consider for quickly forming solid foam.
The TF series of spiral nozzles is a good option for foam control as they can produce a full cone spray pattern with a spray point of up to 170 degrees. This means a single nozzle can treat a large area underneath it, which is particularly important when headroom is limited. The MP and MPL series of nozzles are also popular choices, as they can spray at angles of up to 120 degrees but produce a more even cone pattern than spiral nozzles, resulting in a more uniform foam knockdown effect.
