Water purification system
JUNISLAND's water purification system incorporates filtration, working in concert with Ozone Generator, Lucite Acrylic shell, together they produce clean, safe water while reducing spa tub maintenance.
Ozone system of spa tub
Ozonator work by converting oxygen into ozone via a corona discharge (CD) chip. A clear air line from the ozone generator is connected to your spa tub's plumbing system. The flow created by the pump creates a venturi suction, which draws the ozone into the spa tub water where it dissolves. The ozonator itself is connected to your spa control system, which supplies power and regulates its cycles of operation. Combined with the control pack, the ozonator is actived once the preset circulation is actived.
Power:10 W. Noise: less than 35dB. Pump output: 2-3L/Min .Ozone output: 300mg/hr.
