Dampening Solution Fine Filtration System

  1. 1. technotrans asia-pacific alpha.f1
  2. 2. alpha.f fine filtration Do I need fine filtration? We will help you to find out and at the end of this presentation you will know !2
  3. 3. Content Dampening solution fine filtration Why filtration Filtration principle alpha.f filtration system Operation Conclusion3
  4. 4. Why filtration? Economic pressure demands increased machine availability Stable and reproducible printing quality demand consistent dampening solution IPA-reduced offset printing requires ideal dampening solution quality Special printing processes (e.g. white ink) lead to further dampening solution contamination Conventional, varnish or UV printing White ink IPA-free4 Paper dust
  5. 5. Why filtration? If your dampening solution / dampening pan looks like this, how can you control the printing process? alpha.f fine filtration5
  6. 6. Why filtration? Contamination Q3(x) 100 Particle size distribution Fine dirt, clouding Coarse dirt 0 0,10 1,00 2,00 3,00 5,00 8,00 [µm] Dampening solution dirt can consist of various components such as ink, paper, germs, varnish, etc. Contamination varies with every print job Particles always vary in size distribution, by means the6 contamination is not homogeneous
  7. 7. Filtration Principle technotrans 2 step deep filtration technology Step 1: Cartridge pre-filter The pre-filter serves to remove coarse particles and the contamination from the main fine filter Step 2: Deep-bed main filter The main fine filter has a very high capacity for collecting dirt7
  8. 8. Filtration Principle By-pass filtration 7 main filter + 2 cartridge pre filter By-pass filtration … … does not effect the flow and circulation to the printing units … is consistent and attuned to the filter elements … is a continuous process also when press stops or production ends8 … filter quality is continuously monitored by pressure sensor
  9. 9. technotrans filtration systems alpha.f For all press sizes High filtration quality with 2-step filtration Suitable for long productions runs (24/7) Highly competitive solution for every printing application Pre-filtration system with 2 filter cartridges (coarse filtration) Main fine filtration with 7 filter cartridges9
  10. 10. technotrans filtration systems technical data alpha.f10
  11. 11. Operation alpha.f beta.f Filter maintenance and life time Pre- and main filter are the only consumables Filter life time depends on contamination, and contamination depends e.g. on ink and paper quality as well as the application itself (special colours, little or a lot of spray powder, etc) First time filtration users should clean the entire dampening circulation system (dampening tank, intermediate tank, pipes, trays) Filtration quality is controlled by filter mash size / filter characteristic In general the pre-filter has to be replaced more often than the main filter11
  12. 12. Conclusion Your benefits with technotrans fine filtration systems Permanently clean and clear dampening solution ensures consistent printing conditions and enables high print quality Continuous filtration process reduces the requirement for dampening solution exchange and thus increases productivity and machine availability Significantly reduction in dampening solution exchange cut cost for additives, disposal and overall press operation Continuous filtrations results in a clean dampening solution system (unit, trays, etc.) and thus reduces maintenance costs and press down time.12
  13. 13. Conclusion Do I need fine filtration? …if your dampening solution is dirty …pans and pipes require a lot of maintenance …the printing quality shall be further stabilized …you will go for IPA reduced or free printing …your target is to reduce waste …the press down time shall be further reduced …reduced consumption of press chemicals …general improvement of quality …increase productivity If you say yes to one or all of the above, technotrans alpha.f is one solution to achieve your target13
