Cleaning efficiency class 3

Efficient removal of light and medium soiling

Due to their special nozzle geometry and flow rates from 3 to 169 gal/min at 30 psi, the rotating nozzles in efficiency class 3 are suitable for cleaning medium soiling from tanks and equipment. Such soiling is especially found in the food and beverage industry, but also in the chemical and pharmaceutical industry.

Cleaning efficiency class 3

The free-spinning rotating nozzles in class 3 are made from especially high-grade materials and are available in tank sizes from small to large.

The  HygienicWhirly is perfectly suited for sanitary applications and can also be used for spraying of foam. The Whirly series is also available as an ATEX version and can be used in explosive environments.
