Joyonway Ozone Generator P78B138 - 50mg/hr Corona Discharge Ozonator

Improve water quality and reduce chemical usage with the Joyonway P78B138 Ozone Generator. Designed for use in hot tubs and spas, this compact corona discharge (CD) ozonator produces up to 50mg of ozone per hour, helping to destroy bacteria, break down organic contaminants, and keep water cleaner and fresher between treatments.

Using advanced Corona Discharge technology, the P78B138 delivers a consistent ozone output and offers greater efficiency and longevity than traditional UV-based ozone systems. Ozone is injected into the water through a venturi system, where it works alongside your existing sanitiser to improve water clarity and reduce unpleasant odours.

Suitable for most hot tubs fitted with a venturi injection system, the Joyonway P78B138 is an ideal replacement ozonator for existing spa systems or a reliable upgrade for new installations. The compact design allows for easy installation in confined equipment areas.
