  1. AUTOMATIC ON-LINE BRUSHING FOR AUTOMATIC ON LINE BRUSHING FOR HEAT EXCHANGERS AND CONDENSERS Energy Saving – Performance Enhancing Energy Saving Performance Enhancing

  2. What is EQOBRUSH? Q • An automatic on line cleaning system • An automatic on line cleaning system  for chiller condensers and heat  exchangers  g • Cleans fouling from piping without  shutting down the equipment • Various cleanings per day avoid any  fouling or scaling in pipes • Energy savings and capacity gains  allow an earn‐back period of less  h h than 6 months

  3. Benefits of EQOBRUSH • 10 40% Energy Savings • 10‐40%  Energy Savings • Reduction of machine down‐time for  cleaning cleaning  • Reduction of chemicals for water  treatment and periodical cleaning treatment and periodical cleaning • Increased production capacity • Reduction of water consumption Reduction of water consumption

  4. Principles of Operation p p • The automatic valve reverses the water flow in the Heat • The automatic valve reverses the water flow in the Heat  Exchanger every few hours for 30 sec. • Nylon brushes (housed in baskets connected to the tube • Nylon brushes (housed in baskets connected to the tube  ends) are then propelled through the pipes, cleaning any  scaling or fouling • After the reversion the brushes position in  their baskets, causing no pressure loss Reversed

  5. Benefit: Energy saving gy g Fouling Factor FF Scale  Power   increase  required Examples of the amount of scale  build‐up, and the increase in  power consumption for various  fouling factors is illustrated in the fouling factors is illustrated in the  Fouling Factor Table. thickness in  mm 0.000 0.000 0.00% 0 0001 0.0001 0 03 0.03 1 10% 1.10% 0.0005 0.15 5.50% 0 0010 0.0010 0 30 0.30 11 0% 11.0% 0.0020 0.61 22.0% 0 0030 0.0030 0 91 0.91 33 0% 33.0% 0.0040 1.22 44.0%

  6. Benefit: Energy saving gy g The Graph illustrates potential savings for  diff t d different condenser sizes based on 0.00025 FF  with OLC, compared to 0.002 FF without OLC i b d 0 00025 FF

  7. Benefit: Reduced maintenance cost and  machine down‐time Periodical maintenance of chillers is eliminated by the  EQOBRUSH‐system which means reduction in: – Costs of labor,  – Cost of chemicals – Cost of cleaning equipment g q p – Human exposure to corrosive chemicals

  8. Benefit: Reduced water consumption p • EQOBRUSH allows a higher level of salt concentration (higher  cycle of concentration) in the cooling water cycle of concentration) in the cooling water. – Reduction of blow‐down volumes (eg sewage cost) – Reduction of suppletion water volumes (water cost) pp ( )

  9. Benefit: Capacity p y • Optimal cooling performance  guarantees equipment can run at  i S b top capacity. Sub‐optimal cooling  leads to underperformance • Down time for manual cleaning • Down time for manual cleaning =  capacity loss (up to 5%) i l li

  10. Comparing EQOBRUSH with Ball Based  p g systems WACON‐OLC • Lower investment, simpler  system system • Lower system maintenance,  lower replacement cost Ball Systems • More complex system, requires  higher investment higher investment • Strainer to catch balls needs  replacement, balls get lost and  need replacement  • Pipes in “slow zone” of unit  (outside) get less cleaning cycles (outside) get less cleaning cycles • All pipes get brushed on each  cycle ? all pipes remain clean y p p

  11. Components  p • Standard product lines: – OLC‐Valves in 8 standardsizes ranging from 150‐500 mm (increase by  50 mm) – Brush and Basket sets (2 baskets, 1 brush) in most common sizes from Brush and Basket sets (2 baskets, 1 brush) in most common sizes from  10‐28 mm – Special sizes on request
