NAC Scale Prevention Media Refill for CHF Systems

Switch your CHF system from traditional resin softening to salt free scale prevention. This is NAC (nucleation assisted crystallisation) scale prevention media on its own, supplied loose in a bag to refill the same CHF cartridge your resin currently sits in. Shipped Australia wide with free delivery.

If you're tired of resin that exhausts every year, this is the long life alternative. Empty the spent resin, rinse and pour in the NAC media. No new cartridge, no plumbing changes. The refilled cartridge then runs last in the row and the carbon block moves to the middle: carbon first takes the chlorine out, protecting the media so nothing disrupts the crystal formation the NAC relies on.

What you get (PW-M-NAC-875): salt free NAC scale prevention media, enough to charge one CHF cartridge.

How NAC works: NAC stands for nucleation assisted crystallisation. Instead of softening your water by stripping out minerals, it conditions it, converting dissolved calcium into stable microcrystals that flow through your pipes, elements and glassware without bonding to anything. The minerals stay in your water. Only their ability to form scale is reduced. No salt, no wastewater, no electricity.

Why switch from resin to NAC:

• No salt and no sodium added to your water
• No wastewater, no backwashing, no electricity
• Long media life. Replace approximately every 2 years, depending on your water hardness, rather than yearly
• TDS and pH left unchanged
• Low maintenance scale protection with the minerals retained

The honest trade-off: resin softening gives you that soft water feel on skin and hair because it reduces the minerals. NAC deliberately leaves them in, so you won't get that slippery softened water feel, but you get long term scale protection for your pipes, hot water system and appliances with very little upkeep. If the soft water feel matters most to you, stick with resin. If it's scale protection you're after, NAC is the better long term choice.

The difference in kind: resin is consumed by the softening it does. Its capacity is strongest in the early weeks of a fresh refill and tapers as it's used up, which is why the soft water feel fades before the refill is due. NAC isn't consumed by the crystallisation it drives, so it works the same in month twenty as it does on day one.

Certification: the NAC media we supply is certified to NSF/ANSI/CAN 61 and NSF/ANSI/CAN 372 by the Water Quality Association (WQA) and IAPMO for use in potable water systems. These are material safety certifications. They confirm the media is safe in contact with drinking water. They are not a performance certification and we make no certified performance claim.

Before you order: for use with mains water only, not for water that is microbiologically unsafe or of unknown quality. NAC media conditions scale rather than reducing minerals. It is not a water softener and it is not a substitute for disinfection.
