CIP (cleaning in place)
The wet cleaning (CIP) collectors have an integrated cleaning system. It’s important that the pressure from the spray nozzle is not too high.
After cleaning the drying process can be speeded up by blowing clean warm air at 50 % of the normal flowrate through the filter elements.
Important: No air pressure pulses during the drying process. No washing from the inside of the tubes.
Approximately one hour after the drying process has begun the filter elements should be dry. The permeability of the filter is sufficient enough and the filter can be reused.
Clean the SINBRAN® Filter Elements from the external membrane side only. Washing from the inside of the tubes destroys the membrane.
Pressure washer: This is a simple and effective way to clean the elements. It is important that the water is sprayed at a distance of greater than 40 cm and the water stream hits the elements at an angle of roughly 15 – 20°.
Important: The nozzle has to be as far away from the surface that no hard water jet hits the surface. Otherwise it may damage the membrane surface of the filter element.
Hose pipe: The dust can be rinsed off by using a low pressure method such as a hose pipe.
For hygroscopic dust the surface can be cleaned by using a soft brush, a soft broom to remove the powder from the membrane surface. Occasionally small crusts should remain on the surface as they do not reduce filtration surface noticible but removing may damage the membrane surface. No rubbing!
For the wet cleaning process the temperature of the cleaning liquid should not get above 50 °C. Left over powder or crusts should stay on the surface, as manual removal may cause surface damage to the membrane.
Flushing the elements from the inside out destroys the membrane.
During the wet or dry cleaning process the element gasket must be kept clean and checked for damage. If any damage is visible or you are unsure replace the seal.
Remember that bottom load fitted elements are installed with a distance spacer!
1. Quick Cleaning:
The very smooth ePTFE membrane surface prevents strong dirt or product deposits
2. Easy flushing:
The ePTFE membrane is hydrophobic and supports the wet cleaning process.
3. Wet and dry cleaning:
Hygroscopic product can be removed in a dry state.
4. Entire regeneration:
After cleaning, the filter elements operate at almost the same filtration performance levels and differential pressure than a new filter element.
