Pulse~Pure: Your Cutting-edge Green Alternative to a Chemical Water Treatment.

Being green is no longer an option in our industry, but a necessity. EVAPCO's Pulse~Pure is an eco-friendly alternative for effectively treating cooling water without chemicals.

This solution utilizes pulsed electric fields to control microbiological growth, scale, and corrosion.

Recirculating water from the evaporative cooling system passes through the Pulse-chamber where it is exposed to alternating high-frequency electric fields.

These fields impact both the surface charge of small suspended particles and free-floating microbial organisms found in the cooling water. Pulse-Pure solves all three critical challenges of water-cooled systems; scaling, biological contaminants, and corrosion.
