Salt-Free Systems
The Crusader Avenger is a simple, efficient salt-free system that prevents hard-water scale and corrosion using Active Armour — and controls chlorine and chloramine tastes and odors.

The Crusader Avenger is a simple, effective and budget-friendly salt-free system that prevents hard-water scale and protects your plumbing and appliances from corrosion. It harnesses Active Armour™, a “boundary-zone inhibitor” that stops calcium and magnesium carbonate from forming scale and bonds with exposed metal to form a protective nanolayer — all without adding salt, using electricity, or producing wastewater.
Active Armour works uniformly from 40°F to 140°F (it doesn’t break down like many phosphate compounds), and the Avenger also helps control chlorine and chloramine tastes and odors. It is a water conditioner, not a softener — it controls scale and corrosion rather than removing hardness minerals.

Helps protect plumbing and appliances from corrosion and scale
Scale and corrosion control at a lower operating cost than alternatives
Bonds with inorganic metals and forms a protective nanolayer
Helps prevent costly water-heater and appliance repairs
Say goodbye to chlorine tastes and odors

The Avenger harnesses Active Armour™, a conditioner that acts as a “boundary-zone inhibitor”: it keeps hardness compounds from sticking to themselves — or to your pipes and fixtures — and forming scale. Its proprietary formula works uniformly from 40°F to 140°F, instead of breaking down like many phosphate compounds that clog pipes or build up deposits.
Beyond controlling scale, the safe chemistry of Active Armour™ bonds to the exposed metal of plumbing, faucets, water heaters and appliances, forming a protective nanolayer that guards against corrosion. Active Armour™ is a conditioner, not a softener — it controls scale and corrosion rather than removing hardness minerals.
