SCALE-TECH®

Cartridge-based salt-free scale prevention with FILTERSORB® SP3 and SpinX® distribution technology

Cartridge Scale Prevention

Prevent scale. Protect equipment. Prolong service life.

SCALE-TECH® is a cartridge-based scale-prevention system containing FILTERSORB® SP3 nucleation-assisted crystallization media.

Installed on a cold-water line upstream of water heaters, beverage systems, steam equipment and other water-using appliances, SCALE-TECH® helps reduce calcium-carbonate scale attachment without salt, electricity, chemical dosing or regeneration. The cartridge retains naturally occurring calcium and magnesium while SpinX® distribution technology promotes improved water contact and more uniform utilization of the FILTERSORB® SP3 media bed.

Salt-free / Mineral-preserving / Simple cartridge installation

SCALE-TECH Introduction

One cartridge platform.
Multiple scale-sensitive applications.

SCALE-TECH® is installed on a cold-water supply before equipment requiring protection from calcium-carbonate scale. Model selection depends on continuous flow demand and housing size.

Water Heaters

Scale-management support for compatible storage and instantaneous water heaters.

Coffee and Beverage Equipment

Protection for coffee machines, hot-beverage stations and connected brewing equipment.

Steamers and Catering Equipment

Scale prevention for commercial steam equipment and compatible food-service appliances.

Washing Machines and Appliances

Cold-water pretreatment for scale-sensitive domestic and commercial appliances.

Showers and Salon Equipment

Scale-management support for shower fittings and salon water-heating equipment.

Commercial and Light-Industrial Systems

Parallel cartridge arrangements for applications requiring higher continuous flow.

Four scale-management functions engineered into one cartridge platform

NAC

Nucleation-Assisted Crystallization (NAC-CONTROL™)

FILTERSORB® SP3 promotes formation of microscopic calcium-carbonate crystals with a reduced tendency to attach to equipment and plumbing surfaces.

SX

Dynamic Media Distribution (SPINX-FLOW™)

Angled openings in the bottom distributor create internal water movement intended to improve distribution across the media bed and reduce channeling.

MK

Calcium and Magnesium Retention (MINERAL-KEEP™)

The process does not intentionally remove hardness minerals or replace them with sodium, helping maintain the water’s original mineral composition.

MF

Scalable Cartridge Configuration (MODULAR-FLOW™)

Four cartridge sizes and parallel installation options allow the system to serve different continuous flow requirements.

Additional Operational Parameters
  • Media: FILTERSORB® SP3
  • Distribution system: SpinX®
  • Installation position: Cold-water line before protected equipment
  • Chlorine tolerance: Up to 3 mg/L or ppm
  • Recommended cartridge replacement: Every two years
  • Utilities required: Electricity, salt/brine regeneration, and backwashing are not required. General pH/TDS reduction is not intended.

Science & Technology

SCALE-TECH® changes the crystallization behavior of temporary hardness rather than removing calcium and magnesium from the water.

  • Heterogeneous Nucleation – FILTERSORB® SP3 provides active surfaces on which dissolved calcium and carbonate species can begin forming microscopic crystals.
  • Reduced Surface Attachment – Once crystallization occurs in the water phase, a portion of the calcium carbonate has less tendency to crystallize directly on heating elements and equipment surfaces.
  • Mineral-Preserving Treatment – Because SCALE-TECH® is not an ion-exchange softener, it does not intentionally reduce total hardness, calcium, magnesium or general TDS.
  • SpinX® Distribution – Internal water movement promotes contact between the influent water and the media, supporting more uniform treatment during service.

Frequently
Asked Questions

Important information about SCALE-TECH® operation, model selection, installation and cartridge replacement.

Contact Support
What is SCALE-TECH®?
It is a cartridge-based scale-prevention system containing FILTERSORB® SP3 nucleation-assisted crystallization media.
Does SCALE-TECH® soften water?
No. It does not remove calcium or magnesium and does not lower measured hardness like an ion-exchange water softener.
How does it help prevent scale?
FILTERSORB® SP3 promotes formation of microscopic calcium-carbonate crystals in the water, reducing the tendency of temporary hardness to crystallize directly on equipment surfaces.
Does the system add salt or phosphate?
No salt, brine or phosphate dosing is required for the published treatment mechanism.
Does it change pH or TDS?
SCALE-TECH® is not intended to produce a significant general reduction in pH or TDS. Actual water chemistry should be verified for the application.
What is SpinX® technology?
SpinX® is an internal distribution design that creates water movement through angled openings, helping distribute flow across the FILTERSORB® SP3 media.
Which model should I select?
Select the model whose continuous service flow meets or exceeds the normal demand. Do not size the system using the temporary maximum flow alone.
Can multiple cartridges be installed in parallel?
Yes. Parallel installation can increase system flow, but the manifolds must provide balanced flow through each cartridge.
Where should SCALE-TECH® be installed?
Install it on the cold-water supply upstream of the appliance or equipment requiring scale protection.
Does it remove chlorine, sediment or contaminants?
SCALE-TECH® is primarily a scale-prevention cartridge. A separate sediment or catalytic-carbon filter may be required for suspended solids, chlorine, chloramine, taste or odor.
How often should the cartridge be replaced?
The manufacturer recommends replacement every two years. Actual replacement may need to occur earlier depending on water quality, usage, fouling and operating conditions.
Will SCALE-TECH® remove existing scale?
It is designed primarily to reduce new scale attachment. Existing deposits may change gradually in some systems, but guaranteed descaling should not be claimed without application-specific evidence.
