ChlorKing® CHLOR 7.5SM Salt Chlorinator

Powerful Salt Chlorination for Demanding Commercial Pool Environments

The ChlorKing® CHLOR 7.5SM is a high-output salt chlorination system engineered for large commercial pools and aquatic facilities. Using patented single-cell technology and operating with just 3,500–5,000 ppm salt, it safely and automatically generates up to 7.5 lbs of chlorine per day, eliminating the need for hazardous chemical storage.

Its compact, bypass-plumbed design fits easily into tight pump rooms, while a digital salinity display, reverse polarity self-cleaning cell, and 15,000-hour lifespan make the CHLOR 7.5SM a top choice for safety, sustainability, and operational efficiency.
