HeroFilters Resin Traps – High Filtering Efficient & Durable Life

Resin traps, also named as media traps, are designed to install on either existing and new build strainer bodies to capture the media and resins from loss and prevent them from traveling downstream.

The resin trap screen is normally closed on one side and has a flange on the other for easy installation to the equipment. The resin trap screen has a continuous slots and smooth surface. It can be made for flow-in-to-out (FITO) or flow-out-to-in (FOTI) filtration. The slot sizes are as small to capture very small particle resins.

The resin traps are commonly made of stainless steel rather than carbon steel in order to avoid problems which often leads to accelerated corrosion.

Working principle

A resin trap is installed at the outlet of ion exchange equipment.

Resin trap is a simple, protective sieving device to ensure ion exchange resin or other filtraion media does not leave the water treatment equipment and travel downstream where it doesn’t belong. Wedge wire screens (Vee wire screens) are installed near the outlet of the water system line and protected by mostly stainless steel housing or plastic housing.

When the resin or media passes by, it can be intercepted and captured by the wedge wire filter screens. At the same time, the captured resin can be discharged out of the system by flushing automatically through the differential pressure between front and rear.

Since the slots in the wedge wire are low to 20 microns and up to 3000 microns to suit different filtration fineness requirements.

Features

  • Continuous slots supply high percent of open area to minimize pressure loss through the system.
  • V-shaped surface wires allow for easy cleaning by backwashing.
  • Stainless steel material owns corrosion resistance and long service life to reduce replacing cost.
  • Anti-plugging structure can reduce downtime and improve efficiency.
  • Customized slots and sizes to accommodate your existing and new-build spooling restrictions, flow rates, pressure and other needs.

Applications

Resin traps or media traps should be installed in the product water line of most resin and media based water treatment equipment like: Softeners, Dealkalizers, Condensate Polishers, Demineralizers, Carbon Filters, Sand Filters, Portable DI Tanks, Greensand Filters,and/or Multi-Media Filters.

Also, a resin trap should be considered in the backwash lines of most ion exchange and carbon systems because temperature related flow changes can cause these expensive materials to be sent down the drain.

 

Benefits of our resin traps include:

  • Continuous-slot design provides an increased open area

  • Minimal pressure drop

  • Strong and durable

  • Sight glasses, pressure gauge and blowdown ports supplied

  • Multiple custom housing designs to meet your specific requirements

  • V-shaped surface wires allow for easy cleaning by backflushing

  • Ensures against complete loss of media in the event of a catastrophic failure

  • Great solution for protection of downstream equipment
