Pulse-Pure provides a complete water treatment system for your evaporative cooling equipment which significantly reduces the environmental impacts associated with the production, shipping, handling, and storage of chemicals. This environmentally responsible alternative utilizes pulsed electric fields to control microbiological growth, scale, and corrosion.

Evapco Pulse-Pure is a physical water treatment technology. Recirculating water from the evaporative cooling system passes through the Pulse-chamber where it is exposed to alternating high-frequency electric fields. These pulsed electric fields impact both the surface charge of small suspended particles and free-floating microbial organisms found in cooling water. Pulse-Pure solves all three critical challenges of water-cooled systems; scaling, biological contaminates, and corrosion.
