Because of the design and technique Stratos aspirating detectors are suited for a wide variety of environments. Practically every protected room contains a certain amount of pollution. To make sure that the aspirating pipes don’t get clogged, periodic cleaning is needed. For most areas cleaning during the normal annual service interval will be sufficient.
In heavier polluted areas, such as garbage waste plants and cocoa warehouses, a shorter cleaning interval shall be chosen. For installations with very short intervals the SenseTek automatic purge unit is the perfect solution. This unit fully automatically cleans the piping system by blowing compressed air through from the detector side of the pipes. An extra advantage is that the built in particle filter of the detector doesn’t pollute quickly, so the life of the filter expands dramatically.
By blowing pulsating, a vibration occurs in the aspirating pipe so the pollution comes loose more easy and gets blown out of the pipe via the aspirating holes. This pulsating blowing gives the great advantage that the necessary amount of air is reduced, so that the compressed air system or compressor has to start up less frequently. When a compressor is used the kettle volume can be reduced as well.
