L-4946 TAB Title Self-Flushing Filter

DISCOVER
  • Customer experienced clogged furnace spray nozzles due to a neglected cooling tower.Industries for Self-Flushing Filter
  • Small plastic fines from the cooling tower stopped cooling water to furnace wall resulting in a melted wall. Luckily no one was injured.
DIAGNOSE
  • Filtration of 100 micron was targeted for a 36 inch flooded water pipe.
  • A basket strainer would have to be very large to meet the flow and pressure drop requirements.
  • The basket strainer would require periodic maintenance to clean, stopping the water flow and system processes – at $10,000 per hour of lost production.
DESIGN

What We Did: Schroeder Industries employed the RF-3-5 self-flushing filter with uninterrupted flow and only 3-7 PSI drop while flushing.

Course of action

  1. Schroeder Industries chose to use the Automatic Flush Filter RF Series because it removes particulate and flushes automatically.
  2. The variable housing configurations provide the inlet and outlet flanges and the back-flush line to be arranged in various positions, making it possible to integrate the filter easily into any system geometry.
