HEDP
High Efficiency Dual Pass Softening System
On very hard water supplies (> 75 Gpg), it’s common for hard water to “slip” through the system to your taps and appliances.
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.
Certifications
System Certification: IAPMO R & T Certified against NSF/ANSI 44 and CSA B483.1
Fibreglass Pressure Tank and Control Valve Certifications: NSF/ANSI 44 certified for materials and structural integrity
Resin Certification: IAPMO R & T against NSF/ANSI 61 for material safety only
This system is available with your choice of the 89 or 765 valve
Features
Two tank system provides softer, more consistent water quality and reduces hardness slippage or channelling which can occur in single tank systems
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
Brine safety valve provides added overflow protection
Plastic salt grid prevents bridging
48 hour self charging battery back-up
Includes one-piece bypass integrated meter
