RO Series
Reverse osmosis systems engineered to your site's feed-water TDS and hardness — not a generic off-the-shelf unit.
Why ClairHydra RO
Engineered Around Your Site's Water, Not a Shelf Spec
Sized to Your Site's Water
Every RO system is specified against your site's actual feed-water TDS, hardness, and duty cycle before a quotation is issued — not picked off a shelf.
High-Recovery Engineering
Up to 60% recovery* — more purified water delivered per liter of feed, less sent to drain.
Consistent Permeate Quality
Up to 98% salt rejection*, holding permeate TDS below 150 PPM across the RO Series.
Scales With Demand
Five models from 125 up to 1000 LPH*, sized to match your site's peak draw.
*"Up to" values represent maximum theoretical capacity under ideal test conditions — applies to flow rate, salt rejection, recovery. Salt rejection applies across the RO Series (CH125RO–CH1000RO); the 60% recovery figure applies to CH250RO–CH1000RO (CH125RO's maximum recovery is 50%); 1000 LPH is the CH1000RO model's rated output.

†Pre-treatment (Auto Sand Filter) is mandatory above stated TDS/hardness/turbidity thresholds to achieve stated performance.
‡Continuous supply/uptime claims assume adherence to recommended duty cycle and maintenance schedule.
