Verification of Functionality and Coverage
Toftejorg Sanitary Rotacheck
Application
 Toftejorg Sanitary Rotacheck represents an important tool for increasing quality assurance in tank cleaning, since it provides an electronic means of verifying the 3D 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 verification standards are required, e.g. PAT for pharmaceutical industry, 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. The Rotacheck Sensor System is self adjusted according to the tank pressure.
Cleaning Pattern
The above shows the cleaning pattern achieved by a Toftejorg rotary jet head. Toftejorg Sanitary Rotacheck enables the user to confirm that this operation has taken place on individual tank cleaning cycles.
