Cathelco H2O T6.5 Reverse osmosis desalinator

A versatile range of desalinators covering the requirements of small to medium sized luxury yachts.

These fully automatic machines incorporate water quality sensing. As the water is produced it is tested electronically and the pure water is passed to a holding tank. Any which does not reach the standard is rejected and passed overboard via automatic divert valves.

All Cathelco H20 models are available in frames or can be supplied in component form enabling items to be distributed around the yacht to make the most efficient use of available space.

The desalinators are most commonly powered by AC generator, but can also be belt driven from the vessel’s engine or powered by the DC battery supply.
