HEM Series 30 Duplex Reverse osmosis desalinator, 2 x 9,000 to 2 x 15,000 litres/day

The HEM 30 Duplex system is designed to combine two complete RO systems including the sand filters, rehardening filters and membrane cleaning system in one single frame.

Capacities range from 2 x 9 m³/day, 2 x13 m³/day and 2 x 15m³/day, according to whether the unit has two, three or four membranes.
