Product overview
The salt-free alternative to water softeners.
Calmat is an eco-friendly physical water treatment system that protects piping and appliances against scale deposits and rust. Electronic impulses change the crystallization process so hard scale loses its adhesive power.
The system operates without salt or chemicals and installs without cutting the pipe. Material-specific programs support metal, copper, stainless steel, plastic, PVC, PE-X and compound piping.

Calmat FAQs
Answers before you decide.
Final suitability and product selection should be confirmed through an application assessment.
No. Calmat is a physical treatment system. It changes the
crystallization behavior of calcium rather than removing
naturally occurring minerals.
Yes. The impulse cables wrap around the outside of the
existing pipe, allowing do-it-yourself installation on
supported pipe sizes and materials.
The Calmat product described here supports pipe diameters
up to approximately 1.5 inches (38 mm). Suitability should
be confirmed for the specific application.
