Toftejorg Sanitary Rotacheck

Increase Quality Assurance by Verifying Coverage
Toftejorg Sanitary Rotacheck


Toftejorg Sanitary Rotacheck represents an important tool for increasing quality assurance in tank cleaning, since it provides an electronic means of validating the 360° impact coverage of the Toftejorg rotary jet head. The system is appropriate wherever rotary jet heads are employed in cleaning tanks. The signal generated by the system can be audible, visual or integrated into the customer’s process control specification. Toftejorg Sanitary Rotacheck is particularly suited to industries where improved validation standards are required, e.g., the pharmaceutical, food and beverage industries.

Working principle

The Toftejorg Sanitary Rotacheck sensor is precisely installed to detect the sweep and impact of fluid jets released as the rotary jet head performs its cleaning cycle. From the geared operation of the cleaning device, and by receiving the impact force from the jets, the sensor provides verification of satisfactory operation. Any back pressure in the tanks is accounted for.
