DEL Ozone Eclipse-4
The DEL Ozone Eclipse-4 leads the list among ozone generators thanks to its robust ozone output and proven reliability for high‑demand hydrotherapy and contrast therapy systems, where powerful oxidation accelerates biofilm and contaminant control. Financially it can reduce chemical consumption versus UV-only units, though it requires appropriate ventilation and ozone management compared with UV technologies like ClearRay and Paramount.
