The BETE MicroWhirl nozzles deliver exceptional fine mist or fog, featuring a robust, pinless design that guarantees drip-free operation. Each nozzle is equipped with a 70-micron polypropylene filter, while a 200-mesh 316 stainless-steel filter is also available as an alternative option. A safety wire hole is also available for added security.

The nozzle functions effectively at a minimum pressure of 100 PSI (7 BAR), offering a range of spray options that include mist at lower pressures and fog at higher pressures. The droplets produced are generally small enough for buoyancy to play a significant role, making them appear to float rather than fall. In reality, these particles descend very slowly when there is no upward airflow present.

In 2002, BETE engineers secured a patent for the MicroWhirl fine misting nozzle, which represents a significant advancement in misting technology. Traditional misting and fogging nozzles typically rely on either impingement or air-atomizing designs to generate small droplets. In contrast, the innovative design of misting nozzles employs a swirl chamber to transform fluid head pressure into kinetic energy. This process allows the discharged fluid to break into droplets through centrifugal force. The MicroWhirl nozzles enhance this concept by utilizing a vortex to produce a fine mist, thereby improving both reliability and performance over conventional methods.

Customers trust the MicroWhirl misting nozzles for the finest hydraulic atomization, especially under critical conditions. They are ideal for cooling, humidification and complete evaporation. If you have questions about the MicroWhirl nozzle, or anything regarding EXAIR and BETE products, please do not hesitate to reach out.
