Using Hydrospers, press felts and guide rolls are continuously cleaned and remain free of soiling.
- Hydrospers is added by means of low or high pressure showers.
- To obtain best results, it is recommended to treat two felts so that each side contacts a felt. Thus, sticky deposits in the dryer section are significantly reduced as a side effect. Additionally, then can be reduced further by treating the drying fabrics with Polyprevent.
- Depending upon the contamination, the dosage rate is roughly 5 to 20 ml per minute per m wire width.
