185 HEDP High Efficiency Dual Pass Softening System

On very hard water supplies (> 75 gpg), a common problem with single tank water softeners is the occurrence of hardness leakage or ‘slippage’ as the extreme hardness will find a channel through the resin bed.

The High-Efficiency Dual Pass (HEDP) Water Softener uses a two tank system to prevent this problem.

The first tank acts as the workhorse by significantly reducing the water hardness. The second tank acts as a ‘polisher’ and prevents slippage as the overpowering high hardness condition has been significantly reduced.

This also increases the contact time with the softening resin meaning more consistent, softer water. Salt efficiency is even more important on high hardness situations.

The WaterGroup HEDP offers salt-efficient reverse flow regeneration with precision brining for ultimate salt savings.

  • Perfect for high hardness (typically > 75 gpg) residential and light commercial applications such as boiler feed systems

  • More cost effective than larger single tank systems

  • Reverse Flow Regeneration preserves unused portion of softening bed from unnecessary exchange saving salt

  • Precision Brining calculates the exact amount of brine required to regenerate saving up to 30% more salt

  • Backwash Frequency Preset for clean municipal water saves water by matching backwash to water quality need

  • Soft Water Brine Tank Refill keeps tank & injectors clean 0 Automatic Vacation Mode flushes stagnant water

  • Soft Water Recharge Mode ensures soft water during unusually heavy water usage

  • NSF Certified control valve with electronic sensors, adjustable cycles & proven piston, seal & spacer design

  • WQA Tested & Certified against CSA B483.1

  • NSF Certified fibreglass pressure tank

  • WQA Gold Seal Certified cation resin

  • Unique bypass with integrated turbine meter saves space, eliminates connections

  • Time saving quick connect fittings on bypass, drain line, brine line & power cord

  • Brine safety valve provides added overflow protection

  • Plastic salt grid prevents bridging

  • 48 hour self charging battery back-up
